rails_steps.md

Steps in creating a basic rails app

1. Define your model(s)

• What tables should exist in the database?
• What fields should each table have?

2. Define your associations

• What are the relationships between your tables?

3. Generate models
4. Create your controllers
5. Create your views

• Your forms will go in here

6. Define your routes

• Consider using resources
• Consider using nested resources
• You can view your routes on your server at localhost:3000/rails/info/routes

7. Steps for creating validations and displaying errors in the view

• Add validation to your model
• For example: validates_presence_of

8. Within the else statement of your controller (in case it doesn't save)

• Assign the errors to flash
• For example flash[:danger] = model_name.errors.full_messages

9. In your application's layout file (app/views/layout/application.html.erb), display your flash messages

• For example:

  <% flash.keys.each do |f| %>
    <%= flash[f] %> 
  <% end %>
