Why is a shared partial view in a nested layout not working in a Rails functional test?

I have the following code in app/views/foo/index.rhtml:

  <% render :layout => 'bar_group', :locals => {:id => 'gold_bars'} do %>
    <%= render :partial => "bar_score_box", :locals => {:scores => scores} %>
    <%= render :partial => "common/translate_bar_link", :locals => {:bar => bar} %>
  <% end %>

_bar_group.rhtml and _bar_score_box.rhtml are both also in app/views/foo/, but _translate_bar_link.rhtml is in app/views/common/.

This view works just fine when running my Rails app in development mode and hitting it with a web browser. But when I run a functional test that hits the view, I get an error like this:

Exception: Missing template _translate_bar_link.erb in view path
app/views/foo/_bar_group.rhtml:2

app/views/foo/_bar_group.rhtml looks something like this:

<div id="<%= id %>" class="tile">
  <%= yield %>
</div>

So the error is being reported on the yield line.

Again, this works fine through the Rails server, but not when running a functional test. Does anyone have any idea what could be going on here?

Update: It turns out that I had a second render call for the same partial later in my view, which I forgot to change to common/translate_bar_link when I moved the partial from 开发者_JS百科app/views/foo to app/views/common:

    <%= render :partial => "translate_bar_link", :locals => {:bar => bar} %>

Operator error. Sorry for wasting your time. Flagging this question for deletion.

Try tinkering around with the path used in your render(:partial) statements.

Example (notice the slash in front of 'common/translate_bar_link'):

<% render :layout => 'bar_group', :locals => {:id => 'gold_bars'} do %>
  <%= render :partial => "bar_score_box", :locals => {:scores => scores} %>
  <%= render :partial => "/common/translate_bar_link", :locals => {:bar => bar} %>
<% end %> 

Also, sometimes it helps to put the file extension, too, like this (notice the .rhtml):

<% render :layout => 'bar_group', :locals => {:id => 'gold_bars'} do %>
  <%= render :partial => "bar_score_box", :locals => {:scores => scores} %>
  <%= render :partial => "/common/translate_bar_link.rhtml", :locals => {:bar => bar} %>
<% end %>

I am not sure what version of Rails you are using, but maybe you can rename common/translate_bar_link.rhtml to common/translate_bar_link.html.erb
