hello guys

hello guys
both of these 2 automatically update the fields after save()
i want to update just "updated_at" everytime.
created_at = models.DateField(auto_now_add=True)
updated_at = models.DateField(auto_now=True)
I think that is what auto_now=True does, it updates every time there's a change to the field while auto_now_add=True only updates when it is created, might be wrong though, but I think that is what it does
...
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
I think this which is the same as what you posted should work fine
...
the auto_now will updated each time there is a change to that model element, while the auto_now_add will only update when the model element is created
Real
the auto_now will updated each time there is a change to that model element, while the auto_now_add will only update when the model element is created
well
it seems auto_now_add and auto_now dosent work when both are true :))
i removed auto_now_add and it worked
thank you BTW.

You should put your all_data object in context and return the context
Please tell me how do I do
Amir

You may need to update application code to resolve this error.
Or, you can disable collectstatic for this application:

I'd like to model sale of products by weight and measures. So for example a butcher would price chicken by kilo but sell it by piece and the final price would depends on the actual chicken weight. How would you do this with Django-oscar ?

Thank you so much for your reply i recently got to know that,
Now the main problem is to combine pagination, searching and filtering, I used ListAPIView and inhertite the pagination class but due to that i'm.unable to apply filtering in get_queryset function.
Thank you so much
