I had previously found this method referred to in an older API document but it
was marked as being deprecated/removed in later version of Rails.
Does this still work and if so is it going to be removed or replaced with
something else?

to do with the Base.inheritance_column. According to the api docs:

The behaviour of the do-end block with respect to the render method and the
template_path/template_name keys in the method argument list is by design.
These two keys are intentionally discarded by the render method.
However, it there also appears to be a problem when passing the

I would like to use a single form to display multiple existing
associations and to permit additions to those that already exist. In
its simplest form a row in U has an association to a row R through a

Now, in my case both R and U must exist before they may be associated
