Rails - Ransack - search through associations

Question

User has_many profiles and profile has_many email address. I have search form for User and I have field for email. How can I achieve this.

form_for @User.search do |U|
 f.text_field :name, :name_cont
 f.text_field :email, #what should I write here?

Answer 1

I'm unsure if this is the perfect way to do it. You can try adding a

has_many :email, through: profiles in the User model. After doing this, all you might have to do is, :user_emails_cont

Also try :user_profiles_emails_cont , without the has many through relationship.

Answer 2

Example override in the model :

ransacker :devices_count, formatter: proc{ |v|
    data = ContractSection.csa.includes(:contract_section_devices)
    .where("
            (select count(*) from contract_section_devices 
            where contract_section_devices.contract_section_id = contract_sections.id) = #{v.to_i}
    ").map(&:id)
  } do |parent|
parent.table[:id]

end

views: :devices_count_in
