Rails accepts_nested_attributes_for Error, please help me determine this

Question

I try to follow the Active Record Nested Attributes Guide without much success.

I have the following models:

class Contact < ActiveRecord::Base has_many :telephones accepts_nested_attributes_for :telephones end class Telephone < ActiveRecord::Base belongs_to :contact end 

When trying to create a contact:

 contact = { :name => "John", :telephones => [ {:telephone => '787445741'}, {:telephone => '478589658'} ] } Contact.create(contact) 

I get the following error: ActiveRecord::AssociationTypeMismatch: Telephone(#80827590) expected, got Hash(#72886250)

Could you help me find a bug? Is there any code that I should include in contact_controller.rb ?

Answer 1

I started working with the following code:

 params = { :contact => { :name => 'Joe', :permanentcomment => "No Comment", :telephones_attributes => [ {:telephone => '787445741'}, {:telephone => '478589658'} ] }} Contact.create(params[:contact]) 

I passed the wrong arguments to the Contact.create controller ...
