当我发布时，我收到此错误。

未定义的方法“community_community_topic_url”

我的代码是

显示.html.erb

<%- model_class = @community_topic.class -%>
<div class="page-header">
  <h1><%=t '.title', :default => model_class.model_name.human %></h1>
</div>

        format.json { render json: @community_topic.errors, status: :unprocessable_entity }
      end
    end
  end

路线.rb

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

Rake 路由的结果

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

我得到的错误

您的 rake 路线显示该路线实际上是community_topic，因为您使用了:as => 'topic'.

只需将其称为

community_topic_url

在communities_controller.rb，尝试改变

    format.html { redirect_to community_topic_path[@community, @community_topic], notice: 'Community topic was successfully created.' }

至

    format.html { redirect_to community_topic_path(@community, @community_topic), notice: 'Community topic was successfully created.' }

注意括号。

它有效吗？
