I just converted a 1.1 project to edge rails (1.2). In development
with cache_classes set to false I keep getting these weird class
loading errors. A page will load fine, but after going to another page
and coming back I get NoMethodErrors saying a method on my model object
doesn''t exist, when it clearly does exist and worked fine on previous
requests. In another case I get a message saying ''unexpected class
Team, expecting: Team''. I did some minimal debugging and it seems like
the same class name (Team) is getting a different object id. I was
also stepping through reflections.rb and it looks like it''s reloading
classes that don''t need to be reloaded (I hadn''t changed
anything) and
the reloaded classes are incomplete, missing some methods. Or
something. I''m confused at this point.
Setting cache_classes to true makes all the problems go away. I don''t
have these problems in 1.1. Curiously getting rid of a composed_of
aggregation in one model class seems to help I think. At least I seem
to get farther as the rhtml template blows up because it''s expecting
the composite to be there, the one I just removed (so it''s a valid
error). The composite object is a multi-part custom Name object, which
is dead-simple. And I still have problems with other model objects
that don''t have any composed_of declarations. So that might be a
red-herring.
I do have several custom classes that I require in my models and
controllers. In some cases I have several little classes in one file
that gets required in. I also have several model sub-classes for one
inheritance hierarchy in one file.
I''m trying to create a smaller failing test case that I can post by
creating a mini-app that has the problem. However I haven''t managed to
isolate the problem yet. Every time I extract out a smaller bit of the
app the problem goes away. But I haven''t tried that hard yet.
Any clues or ideas as to what to look for?
Thanks.
Steve
