Using class variable

Beginner here, learning ruby on rails by jumping into a project. This question is probably pure ruby and has nothing to do with rails. I also want to note that I'm using Active_Admin.

I have the following 2 classes: Owner and Phone.

class Owner < ActiveRecord::Base
  attr_accessible :email, :password,
  has_many :phones
end

class Phone < ActiveRecord::Base
  attr_accessible :owner_id :model
  belongs_to :owner
end

How would I go accessing the owners email from within the phones model, for example:

form do |f|
  f.inputs "Phone Details" do
    f.input :model
    f.input :owner_id   # This is where I want the email, not the owners id.
  end
  f.buttons
end

It looks like I should review the pickaxe book and refine my ruby before jumping into rails.

Thanks

In this case you should use nested form. Usage of nested form is explained very well in this railscast.

to have both the owner and the phone in one form, your form should look something like this:

form_for @phone do |phone_form|
  phone_form.label :model
  phone_form.text_field :model
  fields_for @phone.owner do |owner_fields|
    owner_fields.label :email
    owner_fields.text_field :email

If you use this method, make sure you can update the Owner from the Phone model by setting accepts_nested_attributes_for :owner on you Phone model.
