Can 'locals' be used with 'collection' when rendering partials in Rails?

Question

Everything works okay when I try to render a partial like this:

= render :partial => "/shared/enquiry/car_type", :collection => @enquiry.available_car_types

However, if I also want to pass a variable (in this case 'path', because I'm sharing this partial across two forms), the path is not available to me:

= render :partial => "/shared/enquiry/car_type", :collection => @enquiry.available_car_types, :locals => {:path => customers_enquiry_path}

I've tried moving things around, but nothing appears to work, leading me to believe one cannot use locals with collections. Any help would be appreciated.

Answer 1

Like the guides said, specify the :as option in the call to the partial

Answer 2

For Rails 4.x, if you pass the collection directly to render (which you must do if you want to use automatic partial selection for a heterogeneous collection), the next parameter is interpreted as a hash of locals.

Try the following:

= render @enquiry.available_car_types, :path => customers_enquiry_path

Answer 3

What version are you using? Using my 2.3.5 I'm able to do just that:

render :partial => "/site_articles/article", :collection => @site_articles, :locals => { :footer => true }

, which you can find explained in other places, such as 3.4.6 of this.
