ActiveRecord::RecordNotFound - 在 Rails 中找不到 id= 的用户

Question

我正在关注本教程 link 进行 JQuery 验证。

在链接中，他们给出的路线如下：

在 routes.rb 中

map.check_email “users/check_email”, :controller => “users”, :action => “check_email”
map.resources :users

因为它抛出错误，我改变了：

  match '/check_email' => 'users#check_email', :as => 'check_email'

  devise_for :users, :controllers => {:sessions => 'sessions'}, :path => '', :path_names => { :sign_in => "login", :sign_out => "logout" }

将 jquery.validate 添加到 assets/javascripts。

users_controller.rb:

def check_email
  Rails.logger.debug "check_email..................."
  @user = User.find_by_email(params[:user][:email])
  respond_to do |format|
   format.json { render :json => !@user }
  end
end

  def show
    @user = User.find(params[:id])
    @hide_logo_section = Rails.application.config.custom.force_report_logo_accounts.include?(@user.account.name)

    respond_to do |format|
      format.html # show.html.erb
      format.json { render :json => @user }
    end
  end

在 session/new 中，登录表单后面是忘记密码。 app/views/sessions/new.html.erb：

<%= semantic_form_for(resource_name, :url => password_path(resource_name), :remote => true, :format => :json, :html => { :id => 'password_reset' }) do |f| %>
          <%= f.inputs do %>        
              <%= f.input :email, :label => 'Your email address', :input_html => {  :id => 'user_email_field',:placeholder => "Enter your email..."}%>
                          <label id="error_explanation1" class="error errorExplanation" style="margin-top:-10px;"></label>

          <% end %>
          <%= f.buttons do %>
            <%= f.commit_button :label => 'Send me that link', :button_html => {:class => 'submit button', :id => 'forgot_password_button', :disable_with => 'Wait...' }%>
          <% end %>

        <% end %>

<script type="text/javascript">
$(document).ready(function () {
  alert('hellllllll');
  $('#password_reset').validate({
    debug: true,  
    rules: {
      'user[email]': {required: true, email: true, 
        remote:'/users/check_email' }
    }
  });
});
</script>

我在上面的脚本中用遥控器调用控制器。 所需的验证和电子邮件验证都很好，但是在检查方法时会抛出错误。事实上，它不会使用 check_email 方法并在日志中显示 id=check_email 。 这是我的日志：

请帮助ActiveRecord::RecordNotFound - 找不到 id= 的用户

Answer 1

问题出在您的路线上。查看rails docs 所说的内容：

Rails 路由按照指定的顺序进行匹配，因此如果您在 get 'photos/poll' 上方有一个资源 :photos，则资源行的显示操作的路由将在 get 行之前匹配。要解决此问题，请将 get 行移到资源行上方，以便首先匹配。

当您调用 URL：/users/check_email 时，实际上您正在执行 users#show 操作。

将您的 check_email 路由更改为类似

get '/users/validation/check_email', to: 'users#check_email', as: :check_email

它会起作用的。

ps：不要忘记更新 javascript 上的 url。
