Thinking Through the Business Startup App Structure for Stages Models

You're at the core design stage for how business creation models should be structured in your Startup Business Builder App. You have four different approaches:

1. Lean Startup (Eric Ries) -- Focuses on MVPs and fast iteration.
2. Effectuation (Sarasvathy, 2001) -- Starts with existing resources rather than external planning.
3. Business Model Canvas (Osterwalder & Pigneur) -- Visual framework for defining a business model.
4. 9 Stages of Enterprise Creation (Your structured framework).

Key Decision: One Model vs. Separate Models?

You need to decide:

• Should you have one universal model with nested sub-models?
• Or separate models for each approach?

Let's analyze both approaches to help you decide.

Approach 1: One Universal Model with All Stages

Structure:

• One Stage model that holds all 9 stages.
• Each Stage contains references to Lean Startup, Effectuation, Business Model Canvas as needed.

Example Model Structure:

ruby

CopyEdit

class Stage < ApplicationRecord
has_many :lean_startup_steps
has_many :effectuation_steps
has_many :business_model_canvas_steps
end

Pros:

✅ More flexible: You can mix approaches and use different methods per stage.\
✅ Scalability: Easy to add new frameworks in the future.\
✅ Guided Flow: Users go through 9 stages, but different approaches can be suggested at each step.

Cons:

❌ More complexity: Users might be confused about which method to follow.\
❌ Not all approaches fit neatly into 9 stages.

Approach 2: Separate Models for Each Business Creation Framework

Structure:

• Separate models for each approach (LeanStartupStage, EffectuationStage, BMCStage, etc.)
• Each follows its own logical progression.

Example Model Structure:

ruby

CopyEdit

`class LeanStartupStage < ApplicationRecord
belongs_to :business_idea
end

class EffectuationStage < ApplicationRecord
belongs_to :business_idea
end

class BMCStage < ApplicationRecord
belongs_to :business_idea
end`

Pros:

✅ Cleaner structure: Each method has its own roadmap without interfering with others.\
✅ User-focused: Users can choose the best model for their idea.\
✅ Less confusion: No mixing of unrelated approaches.

Cons:

❌ Harder to compare methods: Switching between frameworks isn't seamless.\
❌ Duplication risk: Some steps may overlap (e.g., MVP in Lean Startup and Business Model Canvas).

Which Approach Is Better?

If You Want FLEXIBILITY:

Go for Approach 1 (One Universal Model) if:

• You want all users to follow a structured 9-stage process but allow them to pick from different frameworks at each stage.
• You want to integrate AI-powered recommendations (e.g., "Based on your business, we recommend Lean Startup for this stage.").
• Your focus is on blending best practices from multiple methods.

If You Want SIMPLICITY & CLEAR SEPARATION:

Go for Approach 2 (Separate Models) if:

• You want users to choose a single framework at the beginning (e.g., "I want to follow Lean Startup" → System loads only Lean Startup stages).
• You prefer simpler database models without excessive linking.
• You want future-proofing for adding new frameworks easily.

🚀 My Recommendation (Hybrid Approach)

The best approach might be a hybrid of both:

• Main Stage model follows 9 stages.
• Inside each stage, allow users to apply a method (Lean Startup, Effectuation, etc.).
• If a business idea follows only one approach, allow them to stick to it.

Example Rails Models:

ruby

CopyEdit

`class Stage < ApplicationRecord
belongs_to :business_idea
has_many :stage_methods
end

class StageMethod < ApplicationRecord
belongs_to :stage
enum method_type: { lean_startup: 0, effectuation: 1, business_model_canvas: 2 }
end`

This way, users can mix approaches but still follow the 9-stage flow.

Final Thought for Your Walk 🚶‍♂️💭

🔥 Ask yourself:

• Do I want a strict step-by-step flow (one model) or freedom of choice (separate models)?
• Should AI guide users to the best method, or should they choose at the start?
• Do I plan to add more frameworks in the future (e.g., Design Thinking)?

If you're still unsure, I suggest starting with one model with multiple approaches inside stages. You can always separate models later if needed. 🚀

Let me know what you decide after your walk! 😊🔥

Ok, I ask more clearly. I want to have to disposition all kinds of models: Lean Startup, Effectuation, Business Model Canvas and 9 Stages of Enterprise Creation. For now I have implemented first step of business owner characteristics, ater I will add more. I have implemeted somehow business_idea that has SWOT and PESTEL, I implemented business branding which I think we will use inlater stages or mixed somwher so during process of moving through stages we will fill information needed to branding. Give me plese advices how to start for all models, and show all neccessery steps with implementig it. Particuar pints like market reaserch I will imlement next, just i need base to do relations

🚀 Structuring Your Business Creation Models in Your Startup Builder App

You're building an intelligent, structured approach to business creation, combining Lean Startup, Effectuation, Business Model Canvas, and 9 Stages of Enterprise Creation. Since you've already implemented Business Idea, SWOT, PESTEL, and Branding, now is the time to create a strong foundation for these models.

1️⃣ Key Decision: One Model vs. Multiple Models

You need a framework that allows users to choose their preferred business creation model (or mix elements from different ones).

🔹 Recommended Approach: "Universal Stage Model"

• One Stage model, where each stage can belong to any of the four business creation models.
• Each Stage can have optional methods attached (Lean Startup, Effectuation, etc.).
• Users can follow one model strictly OR mix different methods at each stage.

2️⃣ Implementing the Core Models

🔹 Base Models

Business Idea (Already Implemented)

ruby

CopyEdit

class BusinessIdea < ApplicationRecord
has_many :stages
has_many :swot_analyses
has_many :pestel_analyses
has_one :branding
end

Stage Model (New)

ruby

CopyEdit

class Stage < ApplicationRecord
belongs_to :business_idea
has_many :stage_methods
end

Stage Method (New - Connects Lean Startup, Effectuation, BMC, etc.)

ruby

CopyEdit

class StageMethod < ApplicationRecord
belongs_to :stage
enum method_type: { lean_startup: 0, effectuation: 1, business_model_canvas: 2, nine_stages: 3 }
jsonb :details # Stores additional data specific to the method
end

📌 Why use jsonb?

• details field stores unique information per method (e.g., MVP for Lean Startup, Resources for Effectuation).
• Keeps the database clean while allowing flexibility.

3️⃣ Defining Stages for Each Model

Each business creation method has its own stages. We now map them to your system.

🔹 Universal Stage List (Mapped to Models)

4️⃣ Implementing Stage Progression

📌 Each Stage belongs to a BusinessIdea and follows one or more methods.

Assign Stages Dynamically Based on Model

ruby

CopyEdit

`def create_stages_for_business_idea(business_idea, model_type)
stage_definitions = case model_type
when "lean_startup"
[{ name: "Build MVP" }, { name: "Measure & Learn" }, { name: "Validate Idea" }]
when "effectuation"
[{ name: "Start with Available Means" }, { name: "Who You Are" }, { name: "What You Know" }]
when "business_model_canvas"
[{ name: "Key Partners" }, { name: "Key Activities" }, { name: "Value Propositions" }]
when "nine_stages"
[{ name: "Business Owner Characteristics" }, { name: "Business Idea Definition" }, { name: "Market Research" }]
end

stage_definitions.each do |stage_data|
stage = business_idea.stages.create(name: stage_data[:name])
stage.stage_methods.create(method_type: model_type)
end
end`

📌 Now, when a user selects a method, their business idea automatically gets assigned the correct stages.

5️⃣ Handling Stage Transitions

🔹 How Users Progress Through Stages

• Users complete a stage, and then AI recommends the next best step.
• Some stages can be skipped (e.g., a user might not need Lean Startup validation).
• Store progression state in Stage model.

Track Progress

ruby

CopyEdit

`class Stage < ApplicationRecord
belongs_to :business_idea
has_many :stage_methods

enum status: { not_started: 0, in_progress: 1, completed: 2 }
end`

6️⃣ UI/UX: How This Works in the App

1️⃣ User creates a Business Idea.\
2️⃣ They select a Business Creation Model (or multiple methods).\
3️⃣ The system assigns them the correct Stages.\
4️⃣ As they complete Stages, new recommendations appear.\
5️⃣ AI helps them refine their plan.

7️⃣ Future Enhancements

🔥 AI-Powered Recommendations

• Suggest whether a startup should follow Lean Startup or Effectuation based on capital/resources.
• Dynamically adjust BMC elements based on industry research.

🔥 Hybrid Model Support

• Allow users to mix different models per stage (e.g., Lean Startup in Stage 2, then BMC in Stage 4).

🔥 Automated Business Plan Generation

• At the end, the app compiles all completed stages into a structured business plan.

🚀 Final Summary

✅ One Stage model that supports multiple methods (Lean Startup, Effectuation, etc.)\
✅ Each Stage has methods assigned dynamically.\
✅ User selects a framework (or combines them) at the start.\
✅ Tracking progress with status (not started, in progress, completed).\
✅ Future-proof for AI-driven recommendations & auto-generated business plans.

💡 🔥 This structure keeps your app flexible, scalable, and AI-ready. Let me know if you want refinements! 🚀

Why here: def create_stages_for_business_idea(business_idea, model_type) stage_definitions = case model_type when "lean_startup" [{ name: "Build MVP" }, { name: "Measure & Learn" }, { name: "Validate Idea" }] when "effectuation" [{ name: "Start with Available Means" }, { name: "Who You Are" }, { name: "What You Know" }] when "business_model_canvas" [{ name: "Key Partners" }, { name: "Key Activities" }, { name: "Value Propositions" }] when "nine_stages" [{ name: "Business Owner Characteristics" }, { name: "Business Idea Definition" }, { name: "Market Research" }] end stage_definitions.each do |stage_data| stage = business_idea.stages.create(name: stage_data[:name]) stage.stage_methods.create(method_type: model_type) end end you for example give just [{ name: "Business Owner Characteristics" }, { name: "Business Idea Definition" }, { name: "Market Research" }] 3 stages insted 9 and same with rest

ChatGPT said:

Great question! The reason I included only 3 stages per model in the example was to keep the implementation simple and easy to understand. However, in the actual implementation, you should include all 9 stages for each model.

Why Were Only 3 Stages Shown?

1. Demonstration Purposes: The example was meant to illustrate how to structure stage_definitions, not the full data set.
2. Scalability: Once you confirm the logic works, it's easy to expand to all 9 stages.
3. Incremental Development: Instead of overwhelming the system with 9 stages at once, you can first test a few and then expand.

How to Expand to 9 Stages for Each Model

Here's the correct version with all 9 stages per model:

ruby

CopyEdit

`def create_stages_for_business_idea(business_idea, model_type)
stage_definitions = case model_type
when "lean_startup"
[
{ name: "Build MVP" },
{ name: "Measure & Learn" },
{ name: "Validate Idea" },
{ name: "Pivot if Necessary" },
{ name: "Customer Feedback Loop" },
{ name: "Iterations" },
{ name: "Growth Hacking" },
{ name: "Scaling Strategies" },
{ name: "Expansion" }
]
when "effectuation"
[
{ name: "Start with Available Means" },
{ name: "Who You Are" },
{ name: "What You Know" },
{ name: "Who You Know" },
{ name: "Affordable Loss" },
{ name: "Leverage Partnerships" },
{ name: "Adapt to Environment" },
{ name: "Iterate & Co-create" },
{ name: "Exit Strategy" }
]
when "business_model_canvas"
[
{ name: "Key Partners" },
{ name: "Key Activities" },
{ name: "Value Propositions" },
{ name: "Customer Segments" },
{ name: "Channels" },
{ name: "Revenue Streams" },
{ name: "Cost Structure" },
{ name: "Customer Relationships" },
{ name: "Key Resources" }
]
when "nine_stages"
[
{ name: "Business Owner Characteristics" },
{ name: "Business Idea Definition" },
{ name: "Market Research" },
{ name: "Competitor Analysis" },
{ name: "Business Model Definition" },
{ name: "Strategy Development" },
{ name: "Financial Planning" },
{ name: "Legal & Operations" },
{ name: "Business Plan Finalization" }
]
end

# Create each stage for the business idea
stage_definitions.each do |stage_data|
stage = business_idea.stages.create(name: stage_data[:name])
stage.stage_methods.create(method_type: model_type)
end
end`

How This Works in Practice

1. User selects a Business Creation Model (e.g., Lean Startup).
2. The app runs create_stages_for_business_idea(business_idea, "lean_startup").
3. All 9 stages are created for that business idea.
4. The user progresses through the stages step by step.

🔹 Next Steps for You

• Test this with one Business Idea and ensure all stages generate correctly.
• Make sure the stages appear in the correct order when displaying them in the UI.
• Decide whether users can switch methods (e.g., move from Lean Startup to BMC mid-way).

🚀 Now you have all 9 stages for each model, and your framework is ready to scale! Let me know if you need further refinements. 😊

You said:

And second why 9 I told 9 because of one of business creation model by 9 Stages of Enterprise Creation - Dr David Bozward and i need lean and BCM and core 9 Stages of Enterprise Creation - Dr David Bozward there are most important and rest can be mixed and it dosent mean all of theme should be done in 9 stages

🚀 Refining the Stage Structure for Your Business Startup App

Now that we've clarified that 9 Stages of Enterprise Creation is a core framework, while Lean Startup and Business Model Canvas (BMC) follow their own logic, let's refine how we structure the models.

1️⃣ Core Concept: Not All Methods Follow 9 Stages

Since Lean Startup and BMC don't strictly follow 9 stages, we need to structure our system so that:

1. The "9 Stages of Enterprise Creation" remains a structured framework (step-by-step progression).
2. Lean Startup and BMC operate independently but can still integrate into stages where needed.
3. Other models like Effectuation can be mixed in as optional tools.

2️⃣ Recommended Model Structure

Instead of forcing Lean Startup and BMC into 9 stages, we allow each framework to have its own structure while keeping 9 Stages as a central pathway.

🔹 Stage Model (9 Stages Framework)

ruby

CopyEdit

class Stage < ApplicationRecord
belongs_to :business_idea
has_many :stage_methods # This allows Lean, BMC, etc. to integrate into stages
enum stage_type: { nine_stages: 0 } # More types can be added if needed
end

🔹 StageMethod Model (Links to Lean, BMC, Effectuation)

ruby

CopyEdit

class StageMethod < ApplicationRecord
belongs_to :stage
enum method_type: { lean_startup: 0, business_model_canvas: 1, effectuation: 2 }
jsonb :details # Stores additional data per method
end

3️⃣ Implementing Business Models Without Restricting Them to 9 Stages

Instead of trying to fit Lean Startup and BMC into 9 stages, we define them independently but allow them to be linked when needed.

🔹 LeanStartupStage (Independent Flow)

ruby

CopyEdit

class LeanStartupStage < ApplicationRecord
belongs_to :business_idea
enum step: { build_mvp: 0, measure_learn: 1, validate_idea: 2, pivot: 3, growth: 4 }
end

🔹 BMCStage (Independent Flow)

ruby

CopyEdit

class BMCStage < ApplicationRecord
belongs_to :business_idea
enum element: { key_partners: 0, key_activities: 1, value_propositions: 2, channels: 3 }
end

4️⃣ How This Works in Practice

🔹 Example 1: A User Chooses "9 Stages" as Their Path

1. They start with the structured 9 Stages of Enterprise Creation.
2. When they reach the Business Model Definition stage, they can activate the Business Model Canvas.
3. If they are working on Market Research, they can apply Lean Startup for customer validation.

➡️ Result: A structured flow with integrated flexibility.

🔹 Example 2: A User Chooses "Lean Startup" as Their Path

1. They start with Build MVP.
2. They iterate through Measure & Learn → Validate Idea.
3. They reach Pivot and need structured guidance → They can opt into the 9 Stages framework at this point.

➡️ Result: Users don't have to follow 9 stages but can jump in if needed.

5️⃣ Implementing the Relationships in Code

🔹 Allowing Business Ideas to Follow Any Approach

ruby

CopyEdit

class BusinessIdea < ApplicationRecord
has_many :stages # For users following 9 Stages
has_many :lean_startup_stages # If they choose Lean Startup
has_many :bmc_stages # If they choose Business Model Canvas
end

🔹 Assigning Stages Dynamically

ruby

CopyEdit

def create_stages_for_business_idea(business_idea, selected_models)
selected_models.each do |model_type|
case model_type
when "nine_stages"
["Business Owner Characteristics", "Market Research", "Competitor Analysis"].each do |stage_name|
business_idea.stages.create(name: stage_name, stage_type: "nine_stages")
end
when "lean_startup"
["Build MVP", "Measure & Learn", "Validate Idea"].each do |step|
business_idea.lean_startup_stages.create(step: step)
end
when "business_model_canvas"
["Key Partners", "Value Propositions", "Revenue Streams"].each do |element|
business_idea.bmc_stages.create(element: element)
end
end
end
end

6️⃣ Final Summary

✅ 9 Stages of Enterprise Creation remains structured.\
✅ Lean Startup & BMC operate independently but can integrate where needed.\
✅ Users can choose one approach or mix different models dynamically.\
✅ System is flexible for future business creation methods.

🚀 Next Steps:

• Implement dynamic selection where users pick their approach at the beginning.
• Ensure stages appear in the correct sequence on the dashboard.
• Allow users to switch approaches mid-way if needed.

🔥 This keeps your app structured yet flexible, perfect for different entrepreneur types! Let me know what you think! 😊🚀

agian my lady you given me for ech tipe of business creation model just 3 stages but it depens on model and second where ishould put this code: def create_stages_for_business_idea(business_idea, selected_models) selected_models.each do |model_type| case model_type when "nine_stages" ["Business Owner Characteristics", "Market Research", "Competitor Analysis"].each do |stage_name| business_idea.stages.create(name: stage_name, stage_type: "nine_stages") end when "lean_startup" ["Build MVP", "Measure & Learn", "Validate Idea"].each do |step| business_idea.lean_startup_stages.create(step: step) end when "business_model_canvas" ["Key Partners", "Value Propositions", "Revenue Streams"].each do |element| business_idea.bmc_stages.create(element: element) end end end end thanks

ChatGPT said:

1️⃣ Fixing the Stage Counts Per Model

You're absolutely right! I previously showed only 3 stages per model as examples, but each model should have its own full stage progression. Below is the corrected version with full stages per business creation model.

🔹 Corrected Stage Assignments for Each Model

ruby

CopyEdit

def create_stages_for_business_idea(business_idea, selected_models)
selected_models.each do |model_type|
case model_type
when "nine_stages"
[
"Business Owner Characteristics",
"Business Idea Definition",
"Market Research",
"Competitor Analysis",
"Business Model Definition",
"Strategy Development",
"Financial Planning",
"Legal & Operations",
"Business Plan Finalization"
].each do |stage_name|
business_idea.stages.create(name: stage_name, stage_type: "nine_stages")
end
when "lean_startup"
[
"Build MVP",
"Measure & Learn",
"Validate Idea",
"Pivot if Necessary",
"Customer Feedback Loop",
"Iterations",
"Growth Hacking",
"Scaling Strategies",
"Expansion"
].each do |step|
business_idea.lean_startup_stages.create(step: step)
end
when "business_model_canvas"
[
"Key Partners",
"Key Activities",
"Value Propositions",
"Customer Segments",
"Channels",
"Revenue Streams",
"Cost Structure",
"Customer Relationships",
"Key Resources"
].each do |element|
business_idea.bmc_stages.create(element: element)
end
end
end
end

✅ Now, each model has its full stage sequence.\
✅ This allows users to follow their chosen approach completely.

2️⃣ Where to Put create_stages_for_business_idea in Your Rails App

This method is responsible for creating the stages when a business idea is initialized. It should be placed inside a service object or a model callback.

🔹 Option 1: Place in a Service Object (Recommended)

Create a new service:\
📂 app/services/stage_creation_service.rb

ruby

CopyEdit

class StageCreationService
def self.create_stages_for_business_idea(business_idea, selected_models)
selected_models.each do |model_type|
case model_type
when "nine_stages"
[
"Business Owner Characteristics",
"Business Idea Definition",
"Market Research",
"Competitor Analysis",
"Business Model Definition",
"Strategy Development",
"Financial Planning",
"Legal & Operations",
"Business Plan Finalization"
].each do |stage_name|
business_idea.stages.create(name: stage_name, stage_type: "nine_stages")
end
when "lean_startup"
[
"Build MVP",
"Measure & Learn",
"Validate Idea",
"Pivot if Necessary",
"Customer Feedback Loop",
"Iterations",
"Growth Hacking",
"Scaling Strategies",
"Expansion"
].each do |step|
business_idea.lean_startup_stages.create(step: step)
end
when "business_model_canvas"
[
"Key Partners",
"Key Activities",
"Value Propositions",
"Customer Segments",
"Channels",
"Revenue Streams",
"Cost Structure",
"Customer Relationships",
"Key Resources"
].each do |element|
business_idea.bmc_stages.create(element: element)
end
end
end
end
end

How to Use It in Your Controller (e.g., BusinessIdeasController)

ruby

CopyEdit

`class BusinessIdeasController < ApplicationController
def create
@business_idea = BusinessIdea.new(business_idea_params)

if @business_idea.save
  StageCreationService.create_stages_for_business_idea(@business_idea, params[:selected_models])
  redirect_to @business_idea, notice: "Business idea created with stages!"
else
  render :new
end

end
end`

🔹 Option 2: Use a Model Callback (Less Recommended)

Inside BusinessIdea model:

ruby

CopyEdit

`class BusinessIdea < ApplicationRecord
after_create :generate_stages

def generate_stages
StageCreationService.create_stages_for_business_idea(self, selected_models)
end
end`

📌 Why This Is Less Recommended:

• Model callbacks can make debugging harder.
• You can't control when the stages are generated easily.

🚀 Final Summary

✅ Each model now has all its correct stages.\
✅ Use a StageCreationService for better organization.\
✅ Call it inside your BusinessIdeasController#create method.

🔥 Now, your app is structured, scalable, and flexible! 🚀 Let me know if you need anything else! 😊

So it is too many. I am sorry my lady by my brain is fighting with me all the time asking GOD about Dhruvisha. Please do it with me step by step rails scaffolding, or g models etc step by step please

ChatGPT said:

No worries! Let's go step by step to implement your business creation models in Rails. We'll use Rails generators (rails g model, rails g scaffold) to keep things simple and structured.

Step 1: Generate the Business Idea Model

Since every business creation process starts with a Business Idea, let's create that first.

Run in your terminal:

sh

CopyEdit

rails g scaffold BusinessIdea title:string description:text country:string

This will generate:

• business_ideas table with title, description, and country
• Controller, views, and routes for CRUD operations (Create, Read, Update, Delete)

Now, migrate the database:

sh

CopyEdit

rails db:migrate

Step 2: Generate the Stage Model

Each business idea will have stages based on the selected business creation model (Lean Startup, BMC, 9 Stages).

Run:

sh

CopyEdit

rails g model Stage name:string stage_type:string business_idea:references status:integer

What This Does:

• Creates a stages table linked to business_ideas
• Stores name (e.g., "Market Research"), stage_type (e.g., "lean_startup"), and status (not_started, in_progress, completed)

Migrate the database:

sh

CopyEdit

rails db:migrate

Step 3: Generate the Stage Method Model

Each stage can have different business methods (Lean Startup, BMC, etc.).

Run:

sh

CopyEdit

rails g model StageMethod method_type:string stage:references details:jsonb

What This Does:

• Links to a Stage
• Stores which method is used (lean_startup, bmc, etc.)
• Uses details:jsonb to store extra data dynamically

Migrate the database:

sh

CopyEdit

rails db:migrate

Step 4: Define Relationships in Models

Now, open your models and set up relationships.

📂 app/models/business_idea.rb

ruby

CopyEdit

class BusinessIdea < ApplicationRecord
has_many :stages, dependent: :destroy
end

📂 app/models/stage.rb

ruby

CopyEdit

`class Stage < ApplicationRecord
belongs_to :business_idea
has_many :stage_methods, dependent: :destroy

enum status: { not_started: 0, in_progress: 1, completed: 2 }
end`

📂 app/models/stage_method.rb

ruby

CopyEdit

`class StageMethod < ApplicationRecord
belongs_to :stage

enum method_type: { lean_startup: 0, business_model_canvas: 1, nine_stages: 2 }
end`

Step 5: Add Stage Creation Service

Now, create a service to generate stages dynamically.

Run:

sh

CopyEdit

mkdir app/services
touch app/services/stage_creation_service.rb

📂 app/services/stage_creation_service.rb

ruby

CopyEdit

`class StageCreationService
def self.create_stages_for_business_idea(business_idea, selected_models)
selected_models.each do |model_type|
stage_definitions = case model_type
when "nine_stages"
[
"Business Owner Characteristics",
"Business Idea Definition",
"Market Research",
"Competitor Analysis",
"Business Model Definition",
"Strategy Development",
"Financial Planning",
"Legal & Operations",
"Business Plan Finalization"
]
when "lean_startup"
[
"Build MVP",
"Measure & Learn",
"Validate Idea",
"Pivot if Necessary",
"Customer Feedback Loop",
"Iterations",
"Growth Hacking",
"Scaling Strategies",
"Expansion"
]
when "business_model_canvas"
[
"Key Partners",
"Key Activities",
"Value Propositions",
"Customer Segments",
"Channels",
"Revenue Streams",
"Cost Structure",
"Customer Relationships",
"Key Resources"
]
end

  # Create Stages
  stage_definitions.each do |stage_name|
    stage = business_idea.stages.create(name: stage_name, stage_type: model_type)
    stage.stage_methods.create(method_type: model_type)
  end
end

end
end`

Step 6: Modify Controller to Use Service

Open 📂 app/controllers/business_ideas_controller.rb and update the create method:

ruby

CopyEdit

`class BusinessIdeasController < ApplicationController
def create
@business_idea = BusinessIdea.new(business_idea_params)

if @business_idea.save
  StageCreationService.create_stages_for_business_idea(@business_idea, params[:selected_models])
  redirect_to @business_idea, notice: "Business idea created with stages!"
else
  render :new
end

end

private

def business_idea_params
params.require(:business_idea).permit(:title, :description, :country)
end
end`

Step 7: Update Views

Now, we need to let users select which models they want to follow.

Open 📂 app/views/business_ideas/_form.html.erb, and add:

erb

CopyEdit

<%= form.label :selected_models, "Select Business Models" %><br>
<%= check_box_tag 'selected_models[]', 'nine_stages' %> 9 Stages of Enterprise Creation <br>
<%= check_box_tag 'selected_models[]', 'lean_startup' %> Lean Startup <br>
<%= check_box_tag 'selected_models[]', 'business_model_canvas' %> Business Model Canvas <br>

Step 8: Test the Implementation

1️⃣ Start Rails Server

sh
rails s

2️⃣ Go to the Form:\
Navigate to http://localhost:3000/business_ideas/new and create a new business idea.

3️⃣ Check Database for Stages:\
Run:

rails console

Then check:

BusinessIdea.last.stages

If everything is working, you should see stages generated!

Final Summary

✅ Step 1: Created BusinessIdea model (with title, description, country).\
✅ Step 2: Created Stage model (linked to BusinessIdea).\
✅ Step 3: Created StageMethod model (to store Lean Startup, BMC, etc.).\
✅ Step 4: Defined relationships between models.\
✅ Step 5: Added StageCreationService to generate stages dynamically.\
✅ Step 6: Modified BusinessIdeasController to use service.\
✅ Step 7: Updated form to allow users to choose models.\
✅ Step 8: Tested in Rails Console.
