Re: Dynamically adding a field to a model - via contribute_to_class

If I may suggest a better approach: - Make the code as ImageField does (see it's width_field and height_field) - Then focus on writing the migration for this field Unfortunately, I don't see a way for custom fields to provide hints to the migrations framework. So a field that automatically

Re: More bizarre URL behaviour after deploying

That particular issue may be a lighttpd issue, but my question is more general. Unfortunately I don't remember the kind of trouble I was having with uwsgi. Are there any people who have used both uwsgi and gunicorn and have a preference for the former? What benefits have they seen? Antonis

Re: More bizarre URL behaviour after deploying

You're missing the fact that it's the scgi module of lighttpd is what is causing it. uwsgi shouldn't fix it, as it has no idea if this is intentional, for example when using mounts [1]. As can be seen in the WSGI spec, the WSGI client (uwsgi / gunicorn / whathaveyou) should trust what is provided

Re: Migration Woes: TypeError: int() argument must be a string... on ForeignKeys

The issue didn't crop up, because there were no rows when you added the field, so default isn't called. If you had existing data, then it would've triggered. What default should return for foreign keys is actually documented: > For fields like ForeignKey that map to model instances, defaults

RE: FROM ONLY in Postgres back-end

If you want to do auditing of the database, I would look at packages available for Django. This is the first I've read about "temporal tables," and my first impression is that of grave concern. Django-reversion is a popular package: https://github.com/etianen/django-reversion -Original

Re: FROM ONLY in Postgres back-end

Thanks for your replies. I have looked at the other options available. While they are suitable for version control, they're not well suited for queries where you want to see the state of a given object at a given time. "Show me what X looked like on Y date" can be useful, and shouldn't require

Re: More bizarre URL behaviour after deploying

Antonis, Well truth be told I'm with uwsgi only because of the snowball effect you're alluding to, namely we have so many options I'm like looking on-line for what the most popular and recommended one is, and uwsgi has a huge fan base.  As to server, I opted for lighttpd only because I

Re: Email validation in form

First, make sure the field is rendered as an input tag with type "email". If it's not, your Django version is out of date or you're overriding the widget somewhere. Second, read this: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/email#Validation The standard pattern isn't good

Re: Am a new Django User and am finding difficulties making a query to my database

Well, the simplest answer is you used the python shell and not the django shell via `python manage.py shell`. The app not being in installed apps gives a slightly different error and migrations have little to do with it as importing a model doesn't hit the database. So simply use `python

Re: Am a new Django User and am finding difficulties making a query to my database

Did you include your app in the installed apps list in your settings.py file? Did you do the makemigration and migration after creating the model? Check these two steps and then try again. That's what I'm suspecting given the error trace. On Sep 13, 2017 7:13 AM, "Abdul-Waris Dawuda"

What's not clear about the error? There are two admin classes that have invalid list_display_links values. The format is documented: https://docs.djangoproject.com/en/1.10/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_display_links And chances are you have: list_display_links =

RE: Migration Woes: TypeError: int() argument must be a string... on ForeignKeys

Okay, after much investigation, I found that the default value on this exact field was actually a callable that returned an instance of DisplayName rather than the pk. After changing that, the migrations ran successfully. I wonder if Django could provide a better hint of such issues. It’s
