I would like to do the following:
class WSMRTask(GridTask):
tasktype = "wsmr"
mtz_fp = FileField("MTZ file", upload_to=WSMRTask.path_gen)
class GridTask(Model):
tasktype = "unspec"
def path_gen(instance, filename):
return "%s/%s" % (WSMR_RELPATH, self.tasktype, self.taskname,
self.filename)
since the properties to generate the upload_to pathname+filename come from
the model instance itself. I can't do this since the WSMRTask isn't defined
at the point when I reference it (inside the class def). Any good
suggestions about how I can do this *other* than the obvious option of
creating a separate module of functions that support the specific class?
That is *so* not OO, but I'll do it if it is the only option.
