I don't think controllers have anything to do with your question. A controller is a program that receives requests from the browser and processes them, most likely involving models, and then sends a response back to the browser.
What you are talking about, I think, is about activerecord associations. You can make as many associations between models (tables) as you wish. A comment can belong to a poem and also to a post:
class Comment < ActiveRecord::Base belongs_to :poem belongs_to :post end
class Poem < ActiveRecord::Base has_many :comments end
class Post < ActiveRecord::Base has_many :comments end
Hi nirosh,
belongs_to associations represent other models/tables not controllers.
You can have as many different Controllers as you like, created through migrations or manually - they are simply the way of 'getting in' to your application. All the heavy lifting should be done in the models.
You can set your models up as so:
comment has_many: poems has_many: posts
poem belongs_to: comment
post belongs_to: comment
Your poem and post tables would then each have a column/attribute: comment_id
Each poem and each post could then 'attach' themselves to the same comment_id so that each single comment could be associated with both a poem and a post.
You create your post migration the same way you created your poem migration, apart from any additional attributes specifically related to post.
