Using partials on arrays?

I'm confused by how partials behave with respect to arrays.

Simple Example

I have the following in a view:

render :partial => "foobars", :object => [1, 2, 3]

And in _foobars.html.erb, I have

<%= foobars.size %>
<%= foobars[0] %>

The weird thing is that what gets displayed is "444" and "101", not "3" and "1". Is something special happening because I'm passing in an array?

What Jed says works but what you are looking for is really

render :partial => "foobars", :collection => [1,2,3]

Inside the partial, the iteration will happen by itself on the passed array and foobars will hold the array element of each iteration

<%= foobars %>

will give 1, 2 and 3 inside the partial.

I think what you want is:

render :partial => "foobars", :locals => {:object => [1, 2, 3]}

and inside the partial

<%= object.size %>
<%= object[0] %>
