switch images with onclick

Question

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

Answer 1

Are you sure the error is coming from the partial? You are using entity_id in the form_tag. Where is it being defined? title isn't used in the partial. It is used inside of legend though. Is that defined?
