The proper Django way to make a form field required on CreateView, but optional on UpdateView?
Let's say I create an model MyModel instance that has a FileField using CreateView and associated MyModelCreateForm, and now I want to update it without uploading the same avatar image: class MyModel(models.Model): name = models.CharField() avatar = models.ImageField() class MyModelCreateForm(forms.ModeForm): class Meta: model = MyModel exclude = None class MyModelCreate(CreateView): model = MyModel form_class = MyModelCreateForm class MyModelCreate(UpdateView): model = MyModel form_class = ? On the CreateView's form the image is compulsory. If I want to make it optional on the update field, what's the most Django-ish way of doing this? Do I need to make a new form for the UpdateView that inherits from MyModelCreateForm but overrides the ImageField required attribute? Or is there a more "batteries-included" way? -
Django: Avoid showing error details in production
I am trying to make sure that my site is properly protected from showing the details of the error in production. I've been struggling with this for a while, as at beginning I understood that in order to avoid Django from showing the error (module, line of code, etc.) all that was needed was changing DEBUG from TRUE to FALSE in settings.py. However, I realized that Django was still showing error details, so investigating a bit more and I came to know that the following was also needed: TEMPLATE_DEBUG = DEBUG in settings.py 404.html and 500.htmlinside the templates folder Is there anything else needed to make sure that the user does not get those messages? And how does Django deal with the other kind of errors, like 400? I saw here that there are handlers for 400 and 403, but I do not understand it and I don't know if they are needed at all for a basic using case. -
Django migrations mixed up with 'PROTECT' and 'CASCADE'
I am stuck with migrations in django. I have two really basic models that will not migrate: from django.db import models # Create your models here. class Instanz(models.Model): type = models.CharField(max_length=30) angelegt_am = models.DateField(auto_now_add=True) class Person(models.Model): instanz_fk = models.ForeignKey('Instanz', on_delete=models.CASCADE) last_name = models.CharField(max_length=30) first_name = models.CharField(max_length=30) geburtsdatum = models.DateField() It will raise the following exception. I dont get why it will search for a field named PROTECT. I used models.PROTECT in earlier migrations, before switching to CASCADE, but not any longer...

Conditional expressions on numerical data - Python/Django
Let me show you a situation like this: data = [Station.objects .filter(nr=form.cleaned_data['station']) .aggregate(avg=Avg('residual'), stdev=StdDev('residual'), number=Count('residual'), good_observations = Count(Case(When(abs('residual')<250))), outliers=Count(Case(When(abs('residual')>=250))), )] I want to count rows in database with "residual" (float value) smaller or greater than 250 but it doesn't work. First of all: I've got the TypeEror: init() takes either a Q object or lookups as keyword arguments Secondly: abs() function doesn't work due to TypeError and string value as an input. I hope some of you could help me with this problem :) -

Connecting Django +1.10 with MongoDB
Does anybody replaced the default database engine in Django (+1.10) for MongoDB in the last months? All the info I get in Google is like 6 or 4 years ago. The most commons results includes mongodb-engine which requires django-nonrel (a really old fork from Django 1.5), or mongoengine, also an outdated library that give many errors, so when you patch one, you get a new one. I don't know if there is any "new" way to accomplish this. -

Periodic task schedules set through view functions (Django app)
I schedule repeat tasks for my Django app via including them in the CELERYBEAT_SCHEDULE dictionary in my settings.py. For instance: CELERYBEAT_SCHEDULE = { 'tasks.rank_photos': { 'task': 'tasks.rank_photos', 'schedule': timedelta(seconds=5*60), }, 'tasks.trim_whose_online': { 'task': 'tasks.trim_whose_online', 'schedule': timedelta(seconds=10*60), }, } These tasks periodically run (for the life of the app). I was wondering whether there's a way for a regular user of my app to kick off a periodic task? I.e. is there a way to control this kind of scheduling from views.py? If not, why not? And if yes, an illustrative example would be great. Thanks in advance. -

Redirect to referrer page after modal submission in Django
In my Django app, I have a couple of pages to Create poll question /poll/create-question Edit poll question /poll/edit-question/<question_number> Each of those pages has an option to associate the question with a category name from a drop down list. The user can also create a category on the fly, if the required category is not present in the list. On clicking a button to create the category, a Bootstrap modal pops up and the user can input the category name and submit it. This POST request is handled by a separate view function (with urlpattern /poll/create-category). Also, the create category option is available in both the pages (Create & Edit) Things are working fine. Except that I wanted to redirect to the original page (i.e., Create or Edit) after the modal is closed. The request object has a property call HTTP_REFERER which holds the complete url http://servername:port/poll/create-question. But I wanted just the urlpattern of the referrer page /poll/create-question. Is there a way in Django to get that and redirect to the original page upon submitting a modal? How is this kind of feature usually handled in Django? -
