tried the django discord? https://discord.gg/sPxZME3q

yes posted there

#

what I'd do: I'd use "git bisect".

If you're not using "git", well, ... 🤷

bronze veldt Apr 5, 2024, 12:45 PM

#

well i am using git but this is the first pull on the prod server

#

so there is no good commit to reference to in the first place

maiden hound Apr 5, 2024, 1:06 PM

#

I guess simplify it one bit at a time until it works 😐

bronze veldt Apr 5, 2024, 1:37 PM

#

issue resolved

#

something was wrong with how i defined the abstract model, i needed to use

class Meta:
   abstract=True
``` in the default model
