我仍然有嵌套窗体的问题。这里是我的表单代码:双嵌套模型表格
<%= form_for @account do |f| %>
<%= f.label :account_type %><br />
<%= f.text_field :account_type %><br />
<%= f.fields_for :organizations do |builder| %>
<%= builder.label :name %><br />
<%= builder.text_field :name %><br />
<%= builder.label :website %><br />
<%= builder.text_field :website %><br />
<%= f.fields_for :locations do |builder| %>
<%= builder.label :phone %><br />
<%= builder.text_field :phone %><br />
<%= builder.label :toll_free_phone %><br />
<%= builder.text_field :toll_free_phone %><br />
<%= builder.label :fax %><br />
<%= builder.text_field :fax %><br />
<% end %>
<% end %>
<%= f.submit "Add account" %>
<% end %>
账户模式:
class Account < ActiveRecord::Base
has_many :organizations
accepts_nested_attributes_for :organizations
end
的组织模式:
class Organization < ActiveRecord::Base
belongs_to :account
has_many :locations
accepts_nested_attributes_for :locations
end
和定位模式:
class Location < ActiveRecord::Base
belongs_to :organization
end
最后,帐户控制器:
class AccountsController < ApplicationController
def new
@account = Account.new
organization = @account.organizations.build
organization.locations.build
@header = "Create account"
end
def create
@account = Account.new(params[:account])
if @account.save
#handle success
else
render 'new'
end
end
end
这里是我得到的错误:
ActiveRecord::UnknownAttributeError in AccountsController#create
unknown attribute: locations
Rails.root: C:/Documents and Settings/Corey Quillen/My
