Keep It to Just One File

Generally, the idea is keep your app small and store in a single file. Your app will end up with five sections:

1. Camping setup:

       #!ruby
       #!/usr/local/bin/ruby
       require 'rubygems'
       require 'camping'
   
       Camping.goes :Blog
   

2. Models

       #!ruby
       module Blog::Models
         class User < Base; end
         class Post < Base; belongs_to :user end
       end
   

3. Controllers

       #!ruby
       module Blog::Controllers
         class Index < R '/'
           def get; render :index end
         end
       end
   

4. Views

       #!ruby
       module Blog::Views
         def layout
           html { body { self << yield } }
         end
         def index
           div.page "Welcome!"
         end
       end
   

5. PostAmble:

       #!ruby
       if __FILE__ == $0
         Blog::Models::Base.establish_connection :adapter => 'sqlite3', 
           :database => 'blog3.db'
         Blog::Models::Base.logger = Logger.new('camping.log')
         puts Blog.run
       end
   

   • (Optional) You may choose to Give Us a `create' Method right before the postamble.
   • If you're running in a camping server a postamble isn't compulsory

What if Things Get Out of Hand?

If you're piling up models and controllers, your file may begin to exceed 200 lines, which means lots of paging up and down. Go ahead and store your models, controllers and views in three separate files. Your directory structure should end up like this:

 blog.rb
 blog/
   models.rb
   controllers.rb
   views.rb

(Note, for the development reloading to work, your required files (models.rb etc.) must be in a subdirectory named after your app.)

Your blog.rb would still contain the setup (No. 1) and the postamble (No. 5):

 #!ruby
 #!/usr/local/bin/ruby
 require 'rubygems'
 require 'camping'

 Camping.goes :Blog

 require 'blog/helpers'  # if needed
 require 'blog/models'
 require 'blog/views'
 require 'blog/controllers'

 if __FILE__ == $0
   Blog::Models::Base.establish_connection :adapter => 'sqlite3', 
     :database => 'blog3.db'
   Blog::Models::Base.logger = Logger.new('camping.log')
   puts Blog.run
 end

I would place the requires in the order above. Helpers. Then Models, Views, Controllers. The reason being: Controllers often depend on the others.
