Question

这是错误：

No route matches {:action=>"send_to_client", :controller=>"stages"}

它对应于这一行：

<%= link_to "<span class='icon send-to-client-icon' title='Send to Client' id='send-to-client'> </span>".html_safe, send_to_client_stage_path(@stage), :id => stage.id, :confirm => "This will send #{stage.name.capitalize} to #{stage.client.email}. Are you sure you are ready?" %>

在此_show_table.html.erb

中

<%

if @upload != nil
    stage = @upload.stage
end

%>
<h1 class="panel-header">Images</h1>

<% if stage == nil %>
    <div class="images_menu">
        <%= link_to "<span class='icon send-to-client-icon' title='Send to Client' id='send-to-client'> </span>".html_safe, send_to_client_stage_path(@stage), :id => stage.id, :confirm => "This will send #{stage.name.capitalize} to #{stage.client.email}. Are you sure you are ready?" %>      
        <span class="icon compare-icon" data-url="<%= compare_stage_path(stage)%>" title="Compare Images" id="compare-images"> </span>
    </div>
<% end %>

这是我的routes.rb：

resources :stages do
    member do
      get :step
      get :compare
      get :send_to_client
    end
  end

问题是此部分_show_table.html.erb位于我的uploads模型的视图文件夹中...而不是stages模型。

当我在link_to模型中执行stages时，它运行正常。一旦我将它带入uploads模型，就会抛出该错误。

为什么会出现这种情况？

Edit1：以下是send_to_client控制器的stages操作：

def send_to_client
        stage = Stage.find(params[:id])
        ClientMailer.send_stage(stage).deliver
        if ClientMailer.send_stage(stage).deliver
            flash[:notice] = "Successfully sent to client."
            redirect_to("/")
        else
            flash[:notice] = "There were problems, please try re-sending."
            redirect_to("/")
        end
    end

Answer 1

如果你使用send_to_client_stage_path(nil)，

Rails会引发一个ActionController :: RoutingError。

您正在混淆@stage和stage。如果您未在控制器操作中定义@stage，则它将为nil并且错误会增加。在这种情况下，只需使用@upload.stage。

像：

<% if @upload.stage %>
  <%= link_to "...", send_to_client_stage_path(@upload.stage), :confirm => "..." %>
<% end %>

如果您想使用@stage，只需在@stage = @upload.stage的操作中定义它，然后使用它而不是@upload.stage：

<% if @stage %>
  <%= link_to "...", send_to_client_stage_path(@stage), :confirm => "..." %>
<% end %>

Answer 2

应该是

send_to_client_stage_path(stage)

而不是

send_to_client_stage_path(@stage)

它应该是“除非”，而不是“如果”在这里，对吧？

<% unless stage.nil? %>

另外，不要忘记你可以使用“除非”，它有时更好

if @upload != nil
    stage = @upload.stage
end

- ＆GT;

stage = @upload.stage unless @upload.nil?

对于存在的路线，为什么我会得到“无路线匹配”？
