Question

我有一个link_to，可以将用户带到他们的个人资料页面。以前它曾经工作但现在我继续获得一个未初始化的常量UsersController。

路线：

Rails.application.routes.draw do
  resources :users
  resources :questions

  devise_for :users
  root 'home#index'
  get '/users/:id' => 'home#profile'
end

Index.html.erb：

<div class="row">
    <div class="col-md-8">
    <% if @questions.any? %>
        <% @questions.each do |question| %>
      <div class="well">
          <div class="media">
            <a class="pull-left">
            <% if question.user.avatar.blank? %>
                <img src="http://www.adtechnology.co.uk/images/UGM-default-user.png" style="width: 75px;">
            <% else %>
                <%= image_tag question.user.avatar, :style => "width:75px;" %>
            <% end %>
            </a>
            <div class="media-body">
                <h4 class="media-heading"><%= link_to question.title, question_path(question), :class => "ques" %></h4>
              <p class="text-right">By <%= link_to question.user.username, question.user, :class => " bg" %></p> <!-- that's what's causing the error -->
              <p class="text-muted"><%= truncate(question.description, :length => 50) %></p>
              <ul class="list-inline navbar-right list-unstyled">
                <li><span style="padding-right: 10px;" ><i class="fa fa-calendar"></i> asked <%= time_ago_in_words(question.created_at) %> ago </span></li>
              </ul>
           </div>
        </div>
      </div>
        <% end %>
        <% else %>
            <p>No content yet</p>
      <% end %>

PATCH   /users(.:format)    devise/registrations#update
PUT /users(.:format)    devise/registrations#update
DELETE  /users(.:format)    devise/registrations#destroy
root_path   GET /   home#index
GET /users/:id(.:format)    home#profile

正如我之前所说，我真的不知道导致错误的原因。它昨天工作正常，我根本没有做任何改变。

Answer 1

您应该使用<%= link_to home_profile(question.user.id) %>。

假设 question.user.id 获取用户的相应ID。

使用params [：id]在Profile控制器中访问用户的ID。

Answer 2

我通过将资源放在底部来修复它：

Rails.application.routes.draw do
  devise_for :users
  root 'home#index'
  get '/users/:id' => 'home#profile'
  resources :users
  resources :questions
end

我的猜测是它覆盖了devise_for :users

路由错误UsersController
