where do these "not-found" wagtail errors come from?
This is a chunk of my HTTP logs from django v3.2 running wagtail. Looks as though django is trying to tell me where the missing media is but not able to. Because this is a thicket page with gallery sub-images of "featured pages" the view source in my browser doesn't reveal the image file attempt, but I am assuming it is the same issue as OP's with misconfigured MEDIA_ROOT. Strangely, not seeing any errors in the page's linked images when I bring the child page up in wagtail admin. Anyone have an idea why the missing image won't bubble up to the HTTP logs, or what causes the "media/not-found" substitution for the "real" item causing the 404, or how to unravel the error stack? I've found multiple instances of "not-found", but only in the wagtail "site-packages" /lib/python3.8/site-packages/wagtail folder. None of them give me an indication of why the page (or usually image) causing the 404 isn't returned in the HTTP logs but just the "not-found" URL. I could see what the missing image was (part of a block), and it actually wasn't missing, but possibly a cached copy of the page was causing the "not-found" error to be substituted. [25/Aug/2021 … -
How do I switch a dictsort in Django with a click of a button?
I'm trying to make a button that whenever someone clicks on it it'll change my dictsort to sort by a different attribute instead. Here's my code. I don't have any errors but the button isn't doing anything. I want the dictsort to switch to sorting by date if someone clicks on the button instead of sorting by authors which is the default. Thanks in advance. <button type="submit" onClick="{change text.for-loop|dictsort:'date'}"></button> <ol class="text"> {% for paragraph in paragraphs|dictsort:"authors" %} <div>{{paragraph.text}}</div> {% endfor %} </ol> -

Linux python django site-packages not recognized in envelope
I have tried to create envelope on my linux pop os system using miniconda. When I activate it, I can install packages using pip, but when I run my django instance it doesn't find the modules. If I type which python is shows the miniconda path correctly. I can look in the site-packages folder and see the packages installed. I've tried installing django-anymail and corsheaders and they are both not being found. It does find my locally installed apps. If I use the command line and open python and then import, it does not recognize my modules installed in the virtual envelope either. I thought it was a problem with conda, so I also created an envelope using python's native method: python3 -m venv I have the same problem with it finding pip install site-packages. Is there a command I can run to show all available packages? -
Model-wide validation for a Field type in Django ie., validate that all DecimalField of a model is greater than 0
I have three Decimal fields that all have the same validator: ` class MyModel(models.Model): one = models.DecimalField(validators=[great_than_zero]) two = models.DecimalField(validators=[great_than_zero] three = models.DecimalField(validators=[great_than_zero] ` Is there a pythonic way to enforce this validator for the entire model, so that no Decimal Field can have a negative number. If I know that all of my Decimal fields will be positive, it would be nice to not right the same piece of code for each one. -

Django - add required auto-generated `uuid4` to existing project
I'm trying to add internal_code to a Django Model in the existing project. internal_code = models.CharField(max_length=128, default=uuid.uuid4, unique=True) The problem is that when running migrate, Django raises IntegrityError: DETAIL: Key (internal_code)=(b24f1ca6-bd90-4c91-87b0-5f246a4057e1) is duplicated. I understand that this problem exists only during migrate as it is generated just once.
