metaclass on model class calling db.models.options method vs django 1.7

Hi guys, I am using a metaclass to standardize how I link two classes, on Django 1.6. This is done in order to have a generic way of connecting classes without having to know the name of the fields being linked. Basically, I have in my metaclass '*post_new*' method to get the 'other' model, us

Re: Is it wrong to disable a lot of the core django features?

Hi all, I agree that it's perfectly fine to not use the built in auth and admin apps, and people do it all the time. But, I wanted to give a quick proof of concept of using the admin with custom permissions. # models.py from django.contrib.auth.models import AbstractBaseUser from django.db impo

Hi All, If it helps, at work we have upgraded all of our websites to django 1.7, and are only now starting to think about using migrations. It's totally possible to use 1.7 without migrations. It's also worth noting that although Django supports 1.6 for another 4-5 months, that's only for secu

Hi, Wow. Everything you've shown looks right. Here's something to try: replace base_site.html with a completely empty file. That should cause the admin page to be completely blank. If that works, could you post a snippet of where you're changing the template? Are you changing the and expectin

Re: Meta inheritance across abstract base class

Hi, If you define a new class Meta on C, then it will _replace_ the previous class Meta. You can, however have class Meta inherit other class Meta. class Student(CommonInfo): # ... class Meta(CommonInfo.Meta): db_table = 'student_info' https://docs.djangoproject.com/en/dev/topics

Tim, Simon, Thanks for the responses. Looks like django-concurrency is a good fit, and it works the way Tim suggested (so no need to write your own mixins!) One follow-up question: do you have any ideas for conflict resolution? The django-concurrency resolution is pretty basic, but it would be

Hi Jann, I think you'll need to write a custom deletion handler for this. The following should work: from django.db import models class SetNull(object): """Deletion handler that behaves like `SET_NULL` but also takes a list of extra fields to NULLify.""" def __init__(self, *fields

Re: Preventing race conditions when submitting forms

+1 - conflict resolution is not an easy task, and really depends on your business logic/use case. It's worth mentioning that the approach django-concurrency uses may not be suitable for your use case, and in my opinion implementing this restriction on a per model basis is not the best approach, es
