Question

I have the following tag partial

%span.tag-label
  = link_to "#{tag}"  , :controller => "searches", :action => "search_tags", :search_type => search_type,
  :tag_type => tag_type, :tag =>"#{tag}"

and I pass tags to the partial as collection:

= render "shared/tag_item", :collection => @listing.keyword_list, :as => :tag, 
:search_type => "Listing", :tag_type => nil

For some reason, I got this error:

wrong number of arguments (0 for 1) 

in my partial.

If I just put plain text on link_to "text" and :tag =>"text" then it works.
Why my embedded text in "#{tag}" doesn’t work in this case?

Thank you.

When passing local variables to your partial, you have to pass the render method the key :locals.

 render "shared/tag_item", :collection => @listing.keyword_list, :as => :tag, :locals => { :search_type => "Listing", :tag_type => nil }

Though I have to admit, I would have expected this to give a NameError and not an ArgumentError. Do a search_type or tag_type method exist somewhere in your code?
