如何在用户姓名丢失时修复用户个人资料网址？

Question

我使用Devise gem在功能中进行用户注册。我只通过用户注册表单获得email id and password的值。

如果我转到用户的展示页面，则该网址不能很好地描述其内容。它会在网址中显示primary id's值，如下所示

http://localhost:3000/users/17

然后，我决定使用friendly_id Gem。

覆盖默认行为

因此，我没有在注册表单中获得用户的名称。现在，我没有在网址中使用任何其他值。

在这种情况下我该怎么做。请提出一些想法。我该如何处理这个问题！...

Answer 1

No, I don't allow to see other's profile

We have this setup:

This gives us the ability to call the edit and update actions of the users controller with the url: url.com/profile

You'd be able to set it up as follows:

#app/controllers/users_controller.rb
class UsersController < ApplicationController
   def edit
      #use current_user
   end

   def update
      redirect_to profile_path if current_user.update profile_params
   end
end

#app/views/users/edit.html.erb
<%= form_for current_user do |f| %>
   <%= f.text_field ....... %>
   <%= f.submit %>
<% end %>

This sounds like what you need.

If you wanted to set up friendly_id without the comparative username etc, we use a Profile model which allows you to add a username if you wish:

#app/models/user.rb
class User < ActiveRecord::Base
   has_one :profile
   before_create :build_profile
   delegate :name, to: :profile
end

#app/models/profile.rb
class Profile < ActiveRecord::Base
   belongs_to :user

   extend FriendlyId
   friendly_id :name
end

We then manage to look up the profile with a little bit of a hack:

#app/controllers/users_controller.rb
class UsersController < ApplicationController
   def show
      @user = Profile.find(params[:id]).user #-> friendly_id looks up the :name column in users
   end
end

Answer 2

使其成为一种独特的资源

resource :user

然后它就会转到/user

在您的表单中，您需要明确显示网址，因为铁路无法推断它是一种独特的资源

<%= form_for @user, url: user_path %>
