Question

I am trying to pass a variable to a partial so that it can be called within the partial
This is how i am rendering the partial

 = render :partial => "layouts/reveal_delete", :resource => @schedule

and this is how i am calling the variable within the partial, though it doesnt appear to be working

#RevealDelete.reveal-modal
%a.close-reveal-modal ×
  %h3= "Delete #{@resource}"
  %p Are you sure you want to delete this?
  =link_to "Delete #{@resource}", @resource, :method => :delete, :class => "button close-reveal-modal"
  %a.button.alert.close-reveal-modal Cancel

Answer 1

Call it this way:

= render :partial => "layouts/reveal_delete", :locals => { :resource => @schedule }

And then within the partial, you can use it by referring to resource (no @), like this:

%h3= "Delete #{resource}"

Typically, though, you would name your local variable schedule to match the instance variable, so:

= render :partial => "layouts/reveal_delete", :locals => { :schedule => @schedule }

And then you can refer to schedule in your partial.

Also if you want, you can drop the :partial and :locals option keys, and use this shorter syntax:

= render "layouts/reveal_delete", :schedule => @schedule

Here, Rails assumes that if you pass in a string as your first argument, then the first argument is your partial name and the remainder is interpreted as local variable assignments. Here’s an answer discussing this syntax:
