帖子无法更新

标签： ruby-on-rails ruby routing rake

我尝试更新帖子，它告诉我“目标语言已成功更新”但实际上只要我点击更新按钮，帖子就会恢复原状。我在日志中找不到任何错误消息，任何人都可以帮助我吗？

运行rake路线时的结果

   project_target_langs GET    /projects/:project_id/target_langs(.:format)          target_langs#index
                         POST   /projects/:project_id/target_langs(.:format)          target_langs#create
 new_project_target_lang GET    /projects/:project_id/target_langs/new(.:format)      target_langs#new
edit_project_target_lang GET    /projects/:project_id/target_langs/:id/edit(.:format) target_langs#edit
     project_target_lang GET    /projects/:project_id/target_langs/:id(.:format)      target_langs#show
                         PUT    /projects/:project_id/target_langs/:id(.:format)      target_langs#update
                         DELETE /projects/:project_id/target_langs/:id(.:format)      target_langs#destroy
                         POST   /projects/:project_id/target_langs/:id(.:format)      target_langs#update

我的控制器代码

def update

    @project = Project.find(params[:project_id])
    @targetLang = @project.targetLangs.find(params[:id])


    respond_to do |format|
      if @targetLang.update_attributes(params[:targetLang])
        format.html { redirect_to project_path(@project), notice: 'Target language was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: "edit" }
        format.json { render json: @project.errors, status: :unprocessable_entity }
      end
    end
  end

Show.erb 

<% @project.targetLangs.each do |targetLang| %>

    <%= form_for([targetLang.project, targetLang]) do |f| %>

            <%= f.text_field :language, :class => 'textbox1' %> 
            <%= f.text_field :status, :class => 'textbox1' %>
            <%= f.text_area :notes, :size => "30x2", :class => 'textbox1' %>
            <%= link_to 'Remove', [targetLang.project, targetLang],
                    :data => {:confirm => 'Confirm deletion!'},
                    :method => :delete %>
            <%= link_to 'Update', [targetLang.project, targetLang],
                    :method => :update %>

的routes.rb 

Dashboard::Application.routes.draw do
    resources :projects do
    resources :target_langs
    match '/target_langs/:id' => 'target_langs#update', :via => :post   

 end

1 个答案:

答案 0 :(得分：0)

我认为这里存在一个简单的问题。

你有两个链接，一个到：删除（我猜这是有效的），另一个是：更新（不起作用）

简单地说，在HTML中，<a>标记（link_to返回的内容）不会提交表单。

在示例中单击“更新”时，您发送的唯一参数是id。

相反，你应该说submit_tag("Update")

这将提交表格，一切都应该很好。
