Jquery not working with Whitenoise when adding compression and caching support
I have an app that is working fine with static files and jQuery when simply using WhiteNoise. However, I am trying to add the compression and caching support and I am facing some problems. As explained in their documentation, I added: #settings.py STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage' Then I run python manage.py collectstatic, which creates many gzip compressed files. Finally, when I push it to Heroku some Javascript code is not working anymore, and the console shows several errors like this one: Uncaught ReferenceError: $ is not defined And also this one: Uncaught ReferenceError: jQuery is not defined These errors only happen when I push to Heroku, in my local environment with python manage.py runserver everything still works just fine. I tried what the legacy documentation suggests: Troubleshooting If you’re having problems with the WhiteNoise storage backend, the chances are they’re due to the underlying Django storage engine. This is because WhiteNoise only adds a thin wrapper around Django’s storage to add gzip support, and because the gzip code is very simple it generally doesn’t cause problems. To test whether the problems are due to WhiteNoise or not, try swapping the WhiteNoise storage backend for the Django one. If you’re running Django … -
Saving a Model and get it after save to use it as ForeignKey to create another Model
I have the following 2 models: class Note(models.Model): name= models.CharField(max_length=35) class ActionItem(models.Model): note = models.models.OneToOneField(Note, on_delete=models.CASCADE) target = models.CharField(max_length=35) category = models.ForeignKey(Category, blank=True, null=True, on_delete=models.CASCADE) In other models(based on some conditions) I trigger an utility function that create a Note: def create_note(target=None, action=None): note = Note(target=target, name=name).save() transaction.on_commit( ActionItem(note=note, target=target).save()) I get the following error: null value in column "note_id" violates not-null constraint DETAIL: Failing row contains (6, null). If I use: So, I presume the error appears because save, doesn't return anything. I need the Note to pass it as a FK to ActionItem, an be sure it was saved. -

Django signals is functioning even for django - admin when written for a model

I read the source code I found the: There has another type USERNAME_EMAIL : class AppSettings(object): class AuthenticationMethod: USERNAME = 'username' EMAIL = 'email' USERNAME_EMAIL = 'username_email' Where can I set the allauth use the AuthenticationMethod.USERNAME_EMAIL? -
Django modal loginview - error: "form" should contain a valid Django Form

Using django-ipware get_client_ip instead of get_real_ip
In django-ipware version 2.1 ; old get_real_ip function is deprecated. When I use the new get_client_ip ; my test units are not showing the same results. Means that the two functions do not behave the same. The following is an original test from django-ipware test unit (not mine) def test_http_x_forwarded_for_multiple(self): request = HttpRequest() request.META = { 'HTTP_X_FORWARDED_FOR': '192.168.255.182, 10.0.0.0, 127.0.0.1, 198.84.193.157, 177.139.233.139', 'HTTP_X_REAL_IP': '177.139.233.132', 'REMOTE_ADDR': '177.139.233.133', } ip = get_real_ip(request) self.assertEqual(ip, "198.84.193.157") The above works fine of course, but I want to ensure that using the new get_client_ip will give the same results (for a system upgrade purposes). But the test is actually failing the assertion: def test_http_x_forwarded_for_multiple(self): request = HttpRequest() request.META = { 'HTTP_X_FORWARDED_FOR': '192.168.255.182, 10.0.0.0, 127.0.0.1, 198.84.193.157, 177.139.233.139', 'HTTP_X_REAL_IP': '177.139.233.132', 'REMOTE_ADDR': '177.139.233.133', } ip, is_routable = get_client_ip(request) self.assertEqual(ip, "198.84.193.157") resulting: AssertionError: '177.139.233.132' != '198.84.193.157' After digging into the code, I found that the new get_client_ip is not iterating inside the meta like get_real_ip . It checks out the left-most ip (or right-most depending on the settings) and skips to the next meta if a Public IP is not found My question(s) now are: How can I call get_client_ip in a way that returns the same ip returned by … -

Python Django pdfkit wkhtmltopdf UnknownContentError
I'm getting an UnknownContentError when generating a PDF document from a project URL (https://ourcodeworld.com/articles/read/241/how-to-create-a-pdf-from-html-in-django) - using pdfkit (wkhtmltopdf).
