使用 onclick 切换图像
我有一个名为 _avatar.html.erb 的部分 我想传递一个 id 作为名为entity_id 的局部变量，它将是一个对象的id。
<% form_tag({:controller => "avatar", :action => "upload", :id => entity_id}, :multipart => true ) do %>
<fieldset>
<legend><%= title %></legend>
<% if avatar.exists? %>
<%= avatar_tag(avatar) %>
[<%= link_to "delete", {:controller => "avatar",:action => "delete", :id => entity_id},:confirm => "Are you sure" %>]
...
这是对 parital 的调用：
<%= render :partial => 'avatar/avatar', :locals => {:avatar => @avatar, :title => @title, :entity_id => @board.id } %>
当我尝试这样做时，我收到以下错误：
#
当我取出它时，我也得到一个错误，告诉我它找不到局部变量“title” ”。
任何人都可以帮忙这似乎是正确的方法。
提前致谢
I have a partial called _avatar.html.erb
I want to pass in an id as a local variable called entity_id which will be the id of an object.
<% form_tag({:controller => "avatar", :action => "upload", :id => entity_id}, :multipart => true ) do %>
<fieldset>
<legend><%= title %></legend>
<% if avatar.exists? %>
<%= avatar_tag(avatar) %>
[<%= link_to "delete", {:controller => "avatar",:action => "delete", :id => entity_id},:confirm => "Are you sure" %>]
...
Here is the call for the parital:
<%= render :partial => 'avatar/avatar', :locals => {:avatar => @avatar, :title => @title, :entity_id => @board.id } %>
When I try this I get the following errors:
undefined local variable or method `entity_id' for #
When I take that out I also get an error telling me it can't find the local variable "title".
Can anyone help this seems to be the correct way to do this.
Thanks in advance

您确定错误来自部分吗？您在
form_tag中使用entity_id。它是在哪里定义的？部分中未使用title。不过它是在legend内部使用的。是这样定义的吗？Are you sure the error is coming from the partial? You are using
entity_idin theform_tag. Where is it being defined?titleisn't used in the partial. It is used inside oflegendthough. Is that defined?
