Question

I am pretty new at this, so any help is much appreciated.

While building a tabbed interface I am trying to reuse the same partial and controller and pass a :conditions to a controller to build every tab differently.

@wishes_category = Wish.find :all,
:order => 'id DESC',
:conditions => {:user_id => @current_user.id}

First tab would need something like :category_id=>1 in the controller’s :conditions thus limiting what I show in it.
I am trying to pass this condition to a partial which would use the a pre-limited @wishes_category with :category_id=>1

Thanks!

Based on what Erik said, I then limited the @wishes_category this way
<% if category_id == wish.category_id %> in the partial thus solving the problem

You can pass local parameters to a partial through its render tag using something like:

<%= render :partial => 'tab', :locals => {:category_id => 1} %>

This sets a local variable in the partial named category_id equal to 1. In your partial, it would be referenced simply using <%= category_id %>. Now you are able to render the same partial file multiple times in a page with different local variables.

Of course the variable category_id must exist in the partial before being used or it will throw an error. You can protect against this by checking <% if local_assigns[:category_id] %> first.
