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

Question

我正在遵循本教程链接进行JQuery验证。

在这条线路上，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

当它抛出错误时，我更改了：

  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添加到资产/javascripts中。

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

在会话/新建中，登录表单后面跟着忘记密码。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>

我用遥控器在上面的脚本中调用控制器。所需的和电子邮件验证是好的，但它是抛出错误时，检查方法。实际上，它不会转到check_email方法并在日志中显示id=check_email。这是我的日志：

请帮助helpActiveRecord::RecordNotFound -无法用id=找到用户

Answer 1

问题就在你的路线上。检查rails文档说了什么：

Rails路由按照指定的顺序进行匹配，因此，如果您有一个资源: get“照片/轮询”上方的照片将在get行之前匹配该资源行的show路由。要解决这个问题，请将get行移到资源行的上方，以便首先匹配。

当您调用URL：/users/check_email时，实际上是在执行users#show操作。

将您的check_email路由更改为

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

它会成功的。

ps:不要忘记更新javascript上的url。
