Image Fetching

[Chukwudi Onwusa]

I am only being able to fetch image registered only through the admin on
browser user interface. But the one I registered on browser user interface,
whenever I try fetching it through the user interface, it only shows image
icon, but if I upon the image in the admin interface it shows me error like
the one below.
But the one registered through the admin interface has no error, I have
done all the do-ables , but yet no positive results

Sanity check please

[Mike Dewhirst]

In the Django Admin I have a model central to a bunch of FKs and M:Ms 
plus a lot of processing on saving.


This is my solution which seems to work but frightens me a bit.

class Chemical(models.Model):

    # lots of fields

    def save(self, *args, **kwargs):

    self.process_stuff_based_on_field_values_pre_save()

        first = False

        if not self.id:

    first = True

    super().save(force_insert=True, *args, **kwargs)

    if self.id:

            self.create_or_update_a_bunch_of_related_records(first=first)

    super().save(force_insert=False, *args, **kwargs)

    self.create_or_update_a_bunch_of_m2m_records(first=first)

def process_stuff_based_on_field_values_pre_save(self, first=False):
...



def create_or_update_a_bunch_of_m2m_records(self, first=False):
...


    # lots of other methods

Thanks for any warnings, caveats

Cheers

Mike
