What is the right association between these two models?

I am building a blog and I am a Rails newbie. The doubt is about how to stablish the association between these too models: Posts and Languages.

There will be just two languages, and each post will only (belong_to/has) one language. I was thinking that the right thing would be:

class Post < ActiveRecord::Base
  belongs_to :language
end

class Language < ActiveRecord::Base
  has_many :posts
end

Is it the right approach? Cause sounds more natural to think开发者_开发知识库 that a post has_one language and a language belongs_to_many posts but this kind of association isn't possible in rails, am i wrong?.

Sorry for such an newbie question. Thanks in advance.

You are correct. If you have two models in a many-to-one relationship, your only option is to put has_many on the "one" model and belongs_to on the "many" model. So, in your case, you do indeed want the snippet you provided.

Remember that this means your posts table will carry a language_id column (which feels right), and that your code will refer to post.language and language.posts.
