using django with multiple apps

Can anyone point to me in the right direction regarding how to use Django with Multiple apps. I am trying to build website that can work seamlessly that would direct from one view to the other based on some logic. Obviously, I have both o2m (one to many) and m2m (many to many) relationships.

Or you could return a http status 400 if the transaction couldn't be committed. So, the client should re-run the request later. If this is not an option, you should lay upon a queue as you suggested. Bad things always can happen. So, try your best to avoid i/o problems if your clients cannot

Re: Deployment/NameError Problem

The error occurs in line 68 of admin.py. The admin.py you're showing doesn't seem to have 68 lines. Maybe the admin.py you have in development is not the same you have in production. Or the admin.py the system's reading is not the one you think it is (maybe it's reading it from another directory).

Re: DateField default value in SQLite and Postgres

well the ORM does abstract the different API's for each backend, you may give an datetime object and it will take care to format to the appropriate thing the backend needs. you are right that it does not check the type of the value passed, it is a valid point that the library should check the

Re: DateField default value in SQLite and Postgres

Instead of default='17/06/2017', you should write default=datetime(2017, 6, 17). The bug in Django (if it is a bug, and I think it is) is that it does not require you to do so. There's probably a reason for it, but I don't really know.. Regards, Antonis Antonis Christofides

Re: DateField default value in SQLite and Postgres

The fact that some backends are more forgiving is exactly my point. Maybe the migrations engine should always force a datetime object (or at least a -MM-DD notation) to make it work consistently on all backends. On Wednesday, January 4, 2017 at 11:35:38 AM UTC+1, Avraham Serour wrote: > >
