nested attributes with polymorphic has_one model
- by Millisami
I am using accepts_nested_attributes_for with the has_one polymorphic model in rails 2.3.5
Following are the models and its associations:
class Address < ActiveRecord::Base
attr_accessible :city, :address1, :address2
belongs_to :addressable, :polymorphic => true
validates_presence_of :address1, :address2, :city
end
class Vendor < ActiveRecord::Base
attr_accessible :name, :address_attributes
has_one :address, :as => :addressable, :dependent => :destroy
accepts_nested_attributes_for :address
end
This is the view:
- form_for @vendor do |f|
= f.error_messages
%p
= f.label :name
%br
= f.text_field :name
- f.fields_for :address_attributes do |address|
= render "shared/address_fields", :f => address
%p
= f.submit "Create"
This is the partial shared/address_fields.html.haml
%p
= f.label :city
%br= f.text_field :city
%span City/Town name like Dharan, Butwal, Kathmandu, ..
%p
= f.label :address1
%br= f.text_field :address1
%span City Street name like Lazimpat, New Road, ..
%p
= f.label :address2
%br= f.text_field :address2
%span Tole, Marg, Chowk name like Pokhrel Tole, Shanti Marg, Pako, ..
And this is the controller:
class VendorsController < ApplicationController
def new
@vendor = Vendor.new
end
def create
@vendor = Vendor.new(params[:vendor])
if @vendor.save
flash[:notice] = "Vendor created successfully!"
redirect_to @vendor
else
render :action => 'new'
end
end
end
The problem is when I fill in all the fileds, the record gets save on both tables as expected.
But when I just the name and city or address1 filed, the validation works, error message shown, but the value I put in the city or address1, is not persisted or not displayed inside the address form fields?
This is the same case with edit action too.
Though the record is saved, the address doesn't show up on the edit form. Only the name of the Client model is shown.
Actually, when I look at the log, the address model SQL is not queried even at all.
