when using the :object option, the name of the object in the partial
takes the name of the partial. its part of the DRY principal in that
you can reuse the partial without requiring the partial to know the
name of the object you are passing to it. think of it like a method
call. the method itself is not aware of the name of the parameter on
the outside of the function.
def mymethod(arg)
# isn't aware of the name of the argument outside the function
end
