Can you get a Rails partial's name from within the partial?

Is there a variable that contains a partial's name accessible from within the partial?

render partial: 'foo'

In _foo.haml:

.name
  = partial_name # would output "foo"

You can use a helper in application_helper for this and use rubys introspection abilities so you dont have to explicitly pass FILE like in Mikes answer.

def foo                                                                                                                 
  caller_locations(1, 1).first.path                                                                                     
end

In your partial:

    <%= partial_class(__FILE__) %>

In application_helper:

    def partial_class(partial)
        partial.split(".").first.split("/").last.sub(/^_/, "")
    end

Result: partial is '_customer-existing.html.erb', output is 'customer-existing'. I use this constantly for class names on a wrapper div inside the partial, so that I can use the same name in jquery to show/hide the partial.

Example:

<div class='<%= partial_class(__FILE__) %>'>
  stuff here that will be show/hideable by partial name.
</div>

__FILE__ will give you the file name

<% __FILE__.split("/").last.sub(/^_/, "") %>
