Iterating through model fields - Django

问题

I'm trying to iterate through fields as they are written down within my model:

currently I'm using this:

def attrs(self):
  for attr, value in self.__dict__.iteritems():
    yield attr, value

but the order seems pretty much random :(

Any ideas?

回答1:

The _meta attribute on Model classes and instances is a django.db.models.options.Options which provides access to all sorts of useful information about the Model in question.

For fields, it will give you them in the order they were created (i.e. the same order they were declared).

def attrs(self):
    for field in self._meta.fields:
        yield field.name, getattr(self, field.name)
