Store languages for a model

Here is the context : I have Users and I want to store what languages they speak.

How should I do this ? Create a Languages table with association has_many for Users ? Store it as a hstore in a languages User's column ?

Also, I'm using simple-form, I would like to populate a select (:multiple because a User can speak multiple languages) with all the languages, any idea how to achieve that ? Should I create a constant with all the languages ? Maybe a gem that accomplishes that ?

I did my research but couldn't find anything that fits this need.

Looks like a basic M:M relation between User and Language (which is thoroughly described in the Active Record Associations guide).

How about a User model like:

class User < ApplicationRecord
  has_many :user_languages
  has_many :languages, through: :user_languages
end

And a Language model like: 

class Language < ApplicationRecord
  has_many :user_languages
  has_many :users, through: :user_languages
end

And a UserLanguage model like: 

class UserLanguage < ApplicationRecord
  belongs_to :user
  belongs_to :language
end

I imagine you would seed your languages table.
