I'm using rails 3.2 and I building a nested form. But things are not working as I expect. First of all, my model is a Company with has many Addresses. Here is the model
class Company
include Mongoid::Document
include Mongoid::Timestamps
field :name, :type => String
field :description, :type => String
field :order_minimun, :type => Float
belongs_to :user
has_many :addresses
validates_presence_of :name, :description, :order_minimun
validates_length_of :name, minimum:2, maximum: 30
validates_length_of :description, minimum:5, maximum: 140
validates :order_minimun, :numericality => { :only_integer => true, :greater_than_or_equal_to => 0 }
accepts_nested_attributes_for :addresses
validates_associated :addresses
end
class Address
include Mongoid::Document
include Mongoid::Timestamps
include Mongoid::Spacial::Document
field :street, :type => String
field :number, :type => Integer
field :phone, :type => String
field :location, :type => Array, spacial: {lat: :latitude, lng: :longitude, return_array: true }
embeds_many :delivery_zones
belongs_to :company
belongs_to :city
has_many :openingTimeRange
validates_presence_of :street, :number
validates_length_of :street, minimum:1, maximum: 30
validates_length_of :number, minimum:1, maximum: 6
validates_length_of :phone, minimum:5, maximum: 60
attr_accessible :street, :number, :company_id, :city_id, :location, :phone, :delivery_zones, :latitude, :longitude
end
As you can see the Company model has:
accepts_nested_attributes_for :addresses
validates_associated :addresses
So, I think a can build a nested form. Here is the code of the form
<%= form_for [:admin,@company],:url =>admin_company_path(@company), :html => {:class => "form-horizontal"} do |f|%>
<legend><%= t '.legend' %></legend>
<%= group_input_field f, :name%>
<%= group_field_for f, :description do%>
<%= f.text_area :description, :rows => 5%>
<% end -%>
<%= group_input_field f, :order_minimun%>
<%= f.fields_for :addresses do |builder|%>
<%= render 'address_fields', :f=> builder%>
<% end %>
<div class="form-actions">
<%= f.submit :class => 'btn btn-primary btn-large', :disable_with => t('button.saving') %>
<%= link_to t('.cancel', :default => t("helpers.links.cancel")),
admin_companies_path, :class => 'btn btn-large btn-danger' %>
</div>
<% end %>
the _address_fields.html.erb
<%= group_input_field f, :street%>
<%= group_input_field f, :number%>
I have a simple helper to generate the form fields with bootstrap
def group_input_field(f,field, options={})
has_error = f.object.errors.has_key? field
klass = has_error ? "control-group error": "control-group"
content_tag(:div, :class => klass) do
f.label(field, :class => 'control-label')+
content_tag(:div, :class => 'controls') do
f.text_field(field, :class => 'input')+
show_error(f.object,field,has_error)+
show_help(options)
end
end
end
Finaly the controller:
class Admin::CompaniesController < ApplicationController
def new
#crea una nueva compañia
@company = Company.new
end
def edit
@company = Company.find params[:id]
end
def create
@company = Company.new(params[:company])
if @company.save
redirect_to :action => 'index'
else
render 'new'
end
end
def update
@company = Company.find(params[:id])
if @company.update_attributes(params[:company])
redirect_to :action => 'index'
else
render 'edit'
end
end
end
What is happening a couple of things. First, I have a company with two addresses, and I am able to edit the first one, any change on the second one is not persisted. Then the addresses fields are not validated (if i leave everything in blank when i open the form again the addresses were not save and I can see the original values). And when edit a field in any address, and any field value of the company is not valid, after the form is submited i can see the errors on the company model, but the address are displayed with the original values, so the edited values were lost.
Hope be clear.
Thanks in advance.
