【问题描述】:
我在生成用于添加和编辑现有用户的表单时遇到问题。它会生成一个错误的 URL 来提交。我有以下型号:
用户:
class User < ActiveRecord::Base
has_many :organization_users, :class_name => "::OrganizationUser", :foreign_key => :user_id, :dependent => :destroy
has_many :organizations, :through => :organization_users
老师:
class User::Teacher < User
组织:
class Organization < ActiveRecord::Base
has_many :organization_users
has_many :users, :through => :organization_users
组织用户:
class OrganizationUser < ActiveRecord::Base
belongs_to :user, :class_name => "::User"
belongs_to :organization
在我的路线文件中,我创建了以下规则:
namespace :manager do
resources :organizations, :only => [:edit, :update], :controller => "organizations/organizations" do
resources :users, :only => [:index, :show, :new, :create, :edit, :update, :destroy] do
end
end
结束
用户控制器如下所示:
class Manager::UsersController < Manager::ApplicationController
def new
@user = user_scope.new
respond_to do |format|
format.html
end
end
def edit
respond_to do |format|
format.html
end
end
这是我创建的表格:
= simple_form_for [:manager, @organization, @user], :as => :user, :html => {:class => 'form-horizontal', :multipart => true} do |f|
= f.input :type, :as => :hidden, :input_html => {:name => :type, :value => @type}
%ul{:class=>%w(nav nav-tabs)}
......
使用此表单,我可以毫无问题地创建新用户。问题是更新现有的,得到这个错误:
undefined method `manager_organization_user_teacher_path'
我不知道为什么 simple_form 会生成带有用户(老师)类型的 url,这个路径不存在。如何避免这种行为?
谢谢!
编辑
这里我展示了我如何加载@user
用户控制器:
class Manager::UsersController < Manager::ApplicationController
require_power_check
power :crud => :users, :as => :user_scope
before_filter :load_record, :only => [:show,:edit,:update,:destroy]
def load_record
@user = user_scope.find(params[:id])
end
这是我的用户范围权力:
power :users do
types = []
types << 'User::Teacher' if can_organization_teacher_index?
types << 'User::Student' if can_organization_student_index?
types << 'User::Parent' if can_organization_parent_index?
User.active.where("type in (?)",types).includes(:organization_users).where('organization_users.organization_id'=>@organization)
end
我已经尝试过 MaximusDominus 解决方案并且它有效,但很高兴知道它为什么会发生。
