Im使用rails 3.2.3,并且遇到与HABTM关系有关的问题。Ruby on Rails - HABTM NoMethodError
基本上,我有一个用户模型,有一个HABTM与角色模型。
一切工作正常,但是,我现在想要在用户模型和酒店模型之间添加另一个HABTM关系。
除了当我尝试运行我的网页,我收到了(尾-f日志/ development.log):
NoMethodError (undefined method `[]' for :hotels:Symbol):
app/models/user.rb:7
config/routes.rb:6
config/routes.rb:1
我的路线:
Oops::Application.routes.draw do #this is my line 1
get "managers/index"
root :to => "hotels#index"
devise_for :users #this is my line 6
resources :roles
resources :users
resources :managers
resources :hotels
ActiveAdmin.routes(self)
我的用户模型:
devise :database_authenticatable, :recoverable, (...)
has_and_belongs_to_many :roles, :hotels #This is my line 7, if I delete :hotels and all its references in this HABTM relationship, everything works
accepts_nested_attributes_for :roles
attr_accessible :username, :email, :password, :password_confirmation, :remember_me, :role_ids, :hotel_attributes
我的酒店模式:
has_and_belongs_to_many :facilities, :users
has_one :address
accepts_nested_attributes_for :facilities, :address, :users
attr_accessible <all hotel attributes>, :facility_ids, :address_attributes, :user_ids
一切都在努力,直到这种新的关系。我无法在项目中运行任何页面。 任何提示?
谢谢大家。
