Getting fields_for and accepts_nested_attributes_for to work with a belongs_to relationship

Question

I cannot seem to get a nested form to generate in a rails view for a belongs_to relationship using the new accepts_nested_attributes_for facility o

Answer 1

I think your accepts_nested_attributes is on the wrong side of the relationship. Maybe something like this would work?

class Account < ActiveRecord::Base
  belongs_to :owner, :class_name => 'User', :foreign_key => 'owner_id'
  has_many :users
end

class User < ActiveRecord::Base
  belongs_to :account
  has_one :account, :foreign_key => :owner_id
  accepts_nested_attributes_for :account
end

For building the account you want to use build_account.

You can see more examples in the docs.
