I have a Rails question for anybody who can help...
I have a database table of faculty members for a school. The table has the following columns:
- id
- first_name
- last_name
- salutation
- suffix
- years_teaching
I'm trying to render a template to show details about each faculty member on a page. To do so, I tried the following:
<%= render :partial => 'list_entry', :collection => @faculty_members %>According to the Rails documentation, using the :collection property should force the partial to be rendered for each object in the collection. Each time the partial is rendered, a local variable whose name is the singular version of the collection name is created.
To make sure everything was working, I created a simple partial containing the following:
<li><%= faculty_member.last_name %></li>Of course, it didn't work. After toying around for a while, I got this to work:
<% @faculty_members.each do |f| %>
<%= render :partial => 'list_entry', :locals => { :faculty_member => f } %>
<% end %>As far as I can tell, these two commands should be doing the same thing. Am I missing something?

if you are doing:
<%= render :partial => 'foo', :collection => @bars %>Then your erb partial code should be:
<li><%= foo.last_name %></li>not bar.last_name. When you render a partial through a collection, the model fields are made available in a local var with the same name as your partial.
to quote the rails docs:
# Renders a collection of the same partial by making each element # of @winners available through the local variable "person" as it # builds the complete response. render :partial => "person", :collection => @winners -
kyko... Thanks for replying. I should have come back and closed this, because I figured this out a while ago. Since I figured it out, I can't imagine it working any other way.
