iterate through list

[Kai Kobschätzki]

Hi:

I want to do something with the content of a table. Problem is, that the
IDs are not continuous. I tried:

import .models from Journal

last = Journal.obejects.last()
last += 1
for i in range(last):
  try:
    data = Journal.objects.get(pk=i)
    doing something with this data
  except:
    pass

This solution runs but it seems not smart...

I need the try because there a gaps in the table, so I have got e.g.
element 1, element 3, element 8. If there is not an try/except the for
will crash. And I need the last +=1 otherwise the last element won't be
interpret.

Could anyone show me how I could improve it?

Thansk and Greetings

Use:

for data in Journal.objects.all():
