Question

在编辑页面，如果我将验证码留空，然后按“保存按钮”，则会转到#new页面并说“错误的验证码”。事实上，它应该让我再次编辑页面为什么我的控制器不会检测到请求来自编辑页面？

comunity_topics_controller.rb

before_filter :simple_captcha_check, :only => [:update, :create] 


def simple_captcha_check
    if !simple_captcha_valid?
        flash[:error] = 'Wrong Captcha!'

        if request.put? # We came from an edit request
          @community_topic = CommunityTopic.find(params[:id])
          @community_topic.attributes = params[:community_topic]
          render :action => :edit
        elsif request.post? # We came from a new request
          @community_topic = CommunityTopic.new params[:community_topic]
          render :action => :new
        end

    end
end

_form.html.erb

<%= form_for :community_topic, url: community_topic_index_url, :html => { :class => 'form-horizontal' } do |f| %>
  <div class="control-group">
    <%= f.label :title, :class => 'control-label' %>
    <div class="controls">
      <%= f.text_field :title, :class => 'text_field' %>
    </div>
  </div>
  <div class="control-group">
    <%= f.label :body, :class => 'control-label' %>
    <div class="controls">
      <%= f.text_area :body, :class => 'text_area' %>
    </div>
  </div>

  <div class="control-group">
      <div class="controls">
  <%= show_simple_captcha(:label => "human authentication") %>
    </div>
  </div>


  <div class="form-actions">
    <%= f.submit nil, :class => 'btn btn-primary' %>
    <%= link_to t('.cancel', :default => t("helpers.links.cancel")),
                community_topic_index_path, :class => 'btn' %>
  </div>
<% end %>

更新：

的routes.rb

resources :communities, :path => "shop", do
    resources :community_topics, :path => "topic", :as => :'topic'
end

新更新：

耙路线| grep community_topic

           community_topic_index GET    /shop/:community_id/topic(.:format)          community_topics#index
                                 POST   /shop/:community_id/topic(.:format)          community_topics#create
             new_community_topic GET    /shop/:community_id/topic/new(.:format)      community_topics#new
            edit_community_topic GET    /shop/:community_id/topic/:id/edit(.:format) community_topics#edit
                 community_topic GET    /shop/:community_id/topic/:id(.:format)      community_topics#show
                                 PUT    /shop/:community_id/topic/:id(.:format)      community_topics#update
                                 DELETE /shop/:community_id/topic/:id(.:format)      community_topics#destroy

Answer 1

因为请求方法是post而不是put。要使用put请求，您应该写：

<%= form_for @community_topic, url: community_topics_url,

Answer 2

@MKK <%= form_for :community_topic, url: community_topic_url(@community_topic), :html => { :class => 'form-horizontal' } do |f| %>但请在您的佣金路线中查看

为什么它不会检测到请求来自编辑页面？
