Rails 3-嵌套资源路由-一对一关系 [英] Rails 3 - Nested Resources Routing - One to One relationship

问题描述

某些嵌套资源路由遇到麻烦。我想做的是链接到用户的个人资料页面以进行编辑。在我看来，它写为：

Having some trouble with some nested resources routing. What I'm trying to do is link to a user's profile page for editing purposes. In my view it is written as:

<%= link_to "Edit Profile", edit_user_profile_path(current_user) %>

出现以下错误：

No route matches {:action=>"edit", :controller=>"profiles", :user_id=>#<User id: 1, email: "EDITEDOUT", hashed_password: "EDITEDOUT", created_at: "2011-01-20 18:30:44", updated_at: "2011-01-20 18:30:44">}

在我的route.rb文件中，看起来像这样：

In my routes.rb file, it looks like so:

resources :users do
  resources :profiles, :controller => "profiles"
end  

我检查了Rake路线，并将其作为有效选项：

I checked my Rake routes, and it gave me this as a valid option:

edit_user_profile GET    /users/:user_id/profiles/:id/edit(.:format)   {:action=>"edit", :controller=>"profiles"}

我可以手动设置导航。为了获得良好的效果，这里是我的控制器的证明：

Which I am able to manually navigate to. For good measures, here's proof of my controller:

class ProfilesController < ApplicationController
  def edit
    @user = current_user
    @profile = current_user.profile
  end

  def update
    @user = current_user
    @profile = current_user.profile


    respond_to do |format|
      if @profile.update_attributes(params[:profile])
        format.html { redirect_to(orders_path, :notice => "Your profile has been updated.") }
        format.xml  { head :ok }
      else
        format.html { render :action => "edit" }
        format.xml  { render :xml => @profile.errors, :status => :unprocessable_entity }
      end
    end
  end
end

无论如何，我一直在追踪这个问题。任何指针都会有所帮助。对于我的数据库设计，概要文件以一对一关系属于用户。我希望这只是新事物，我没有注意到新的眼睛可能会有所帮助。

Anyway, I've been having some problem tracking this down. Any pointers would help. For my DB design Profiles belong to Users in a one-to-one relationship. I'm hoping it's just something newbish I'm not noticing a new set of eyes might help.

推荐答案

在您的路线上，您会看到它同时期望：user_id 和：id 。在这种情况下，后者指的是用户个人资料。

If you look closely at your route, you'll see that it expects both a :user_id and an :id. The latter, in this case, refers to the user profile.

为了告诉Rails您想要该特定个人资料，您必须同时指定用户和链接中的个人资料，例如：

In order to tell Rails that you want that particular profile, you'll have to specify both the user and the profile in your link, like this:

edit_user_profile_path(current_user, @profile)

现在，Rails将对 current_user ） >：user_id 的一部分，而：id @profile ） $ c>。

Now, Rails will use the first argument (current_user) for the :user_id part of the route, and the second argument (@profile) for the :id.
