really confused.
I don't know Django, so if this is really Django specific, I can't help.
The model definition is omitted but can anyone explain how this methed
(was_published_recently) is given these attributes:
Which attributes are you confused about?
The admin_order_field, boolean, ande short_description attributes of the
method are bound in class code, immediately after the method is defined.
The pub_date is probably an instance attribute of either the Poll class
or the models.Model class. It should probably be defined in the
appropriate __init__ method. In any case it's not a method attribute.
class Poll(models.Model):
# ...
def was_published_recently(self):
return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
was_published_recently.admin_order_field = 'pub_date'
was_published_recently.boolean = True
was_published_recently.short_description = 'Published recently?'
are the names of the attributes already attached to these
functions/methods, or are they being created on the fly with whatever
name you want? As i am unable to comprehend what is going on, i dont
really have a clue as to what each definition is doing and how it
affects the model, even after reading this section of the docs over
and over again im still lost.
This fragment isn't big enough for much else to be told. But I don't
really understand what aspect is confusing you.
Perhaps you didn't realize that a function can have attributes, and that
they can be added to the function at any time after the function is
created. Being a method doesn't change that.
