Compare with:

setup(context, options, block)

Sets up instance variables needed for rendering a partial. This method finds the options and details and extracts them. The method also contains logic that handles the type of object passed in as the partial.

If options[:partial] is a string, then the +@path+ instance variable is set to that string. Otherwise, the options[:partial] object must respond to to_partial_path in order to setup the path.

Parameters

context req
options req
block req
