Question

I have two models, subject and page. I created a one-to-many association between them.

class Subject < ActiveRecord::Base
  has_many :pages
  attr_accessible :name
  attr_accessible :position
  attr_accessible :visible
  attr_accessible :created_at
end

and

class Page < ActiveRecord::Base
  belongs_to :subject

  attr_accessible :subject_id
  attr_accessible :name
  attr_accessible :permalink
  attr_accessible :position
  attr_accessible :visible
  attr_accessible :created_at
end

As mentioned above, I have two models, and I want to access all subject names which are in the Subject model to the page model/controller…

Answer 1

If you want to get all the subjects saved in a subject model use:

Subject.pluck(:name)

or to access a subjects associated with particular page:

page = Page.first
page.subject  #subject object associated with the page
