How to save the values of one model in another?

I have user model and Language model where the language model contains different languages and i want the user to select the languages from that model and it should be stored for the corresponding user. Consider there are five languages A, B, C, D, E then the user has to select from the languages. Suppose user 1 selects A and C whereas user 2 selects B and D then the languages has to be stored for that user. How can i do this? please help me.

You can do it through association,in your case you can try like:

class User < ActiveRecord::Base

has_and_belongs_to_many :languages

end

and

class Language < ActiveRecord::Base

has_and_belongs_to_many :users

end

or may be you can go through with the following links.

You need to model a many-to-many relationship. As explained in the link, this can be done by declaring

class User < ActiveRecord::Base
  has_and_belongs_to_many :languages
end

class Language < ActiveRecord::Base
  has_and_belongs_to_many :users
end

and creating a new table called something like language_users to store user_id and language_id. Each record in this table indicates that a particular user has selected a particular language.
