Inconsistency when rolling back a migration that adds a primary key

Hi all, I've been looking at bug #28542, in which a migration can be played forwards but not reversed. I think I can see what's happening, but I'm not 100% sure what the right resolution is, so I wanted to get some input. The migration in question looks something like this: # Start out with

Hello Brice, Here is the query I sent today, which improves my first suggestion: 1. WITH 2. maybe_found AS (SELECT * FROM t WHERE t.name='nameD'), 3. to_be_inserted AS (SELECT 'nameD' as "name", 'comment13' as "comment"), 4. just_inserted AS ( 5. INSERT INTO t (name, comment) SELEC

Your idea about ignoring conflicts in bulk_create is a great idea, i've made a merge request that attempts to implements this. If anyone has any time to review it it would be much appreciated. I couldn't find a very elegant way of adding it though - Sqlite and mysql need something added just after

Re: WOULD LIKE TO CONTRIBUTE TO DJANGO

Hello, Since I haven't seen positive feedback from a committer, I'm not convinced there's consensus about this change. Also this doesn't look like a particularly easy topic for a beginner. It raises the following questions: - INSERT ON CONFLICT UPDATE would likely be a better option on Postgres

Re: WOULD LIKE TO CONTRIBUTE TO DJANGO

Hello Muhereza, I assume you understand by now Django quite well and are willing to give something "in return". Currently QuerySet.get_or_create() consists of two SQL commands: SELECT + optional INSERT. They cause a concurrent problem, if another get_or_create() is called between the SQL st

Re: Prevent DateRangeField overlap in model?

A pythonic way to do this would be extremely useful if it existed. As you suggested, I did this using a sql exclusion constraint statement on the table and a migration. For example: 000x_your_migration_name.py # -*- coding: utf-8 -*- from __future__ import unicode_literals from django.db im
