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 ar开发者_如何学运维ray?
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] %>
