我正在尝试使用双嵌套路由在simple_form_for
的Rails 3.2中构建@objects
,例如:
/users/1/projects/2/objects
表格是:
<%= simple_form_for @object, :url => user_project_objects_path(@user, @project), :html => { :class => 'form-horizontal' } do |f| %>
在routes.rb中:
resources :users do
resources :projects do
resources :objects do
collection { post :import }
end
end
end
我的问题是:new
控件的create
和Object
操作中包含哪些内容?
到目前为止 - 我收到路由错误 - 我有:
def create
@user = current_user
@project = Project.find_by_user_id(@user)
@object = @project.objects.build(params[:object])
if @object.save
flash[:notice] = "Object was successfully created"
redirect_to user_project_objects_path
else
render 'new'
end
end
def new
@user = current_user
@project = Project.find_by_user_id(@user)
@object = @project.objects.build
end
非常感谢任何建议。
No route matches {:action=>"edit", :controller=>"objects", :user_id=>#<Object id: 8, source_lang_id: 1, source_content: "Kaffehaus", target_lang_id: 2, target_content: "cafe", domain_id: 2, owner_id: nil, created_at: "2013-01-04 06:36:55", updated_at: "2013-01-04 06:36:55", project_id: 2>}
owner_id
(用户,即current_user)未更新 - 这可能是问题(?)

在表单中,您可以使用
simple_form_for([@user, @project, object]) do
您可以使用该关系来获取
等数据@project= current_user.projects
而不是
@project = Project.find_by_user_id(@user)

我在此期间解决了这个问题。也许这可能是其他人在使用双重嵌套路由时的常用指南,例如用户 - &gt;项目 - &gt;对象(has_many,has_many)
在对象控制器新操作中:
@user = current_user
@project = Project.find(params[:project_id])
@object = Object.new
在对象控制器创建操作中:
@user = current_user
@project = Project.find(params[:project_id])
@object = @project.objects.build(params[:object])
@object.owner_id = @user.id #owner id maps to User
路由错误是未指定所有对象,用户,项目和对象的结果 在
user_project_objects_path(@project)
