Allow users to fill out a Django form on their own personal website?
I am wondering if anyone has dealt with allowing Users to fill out a form on their own personal website, which is connected to the Django applications database? The general idea behind this, is allowing say a User (Party Planner in the Django app) to not have to come to the "Django Application" to input an event, rather they go to their own personal website, and input form information there which is POSTed to the Django applications database? It's an idea I have been throwing around, and just looking for some guidance in the right direction. Thank you in advance! -

Django display content of Google Storage PDF within Heroku Site
I have an issue where the service account used to allow the Django application has the permissions to edit and delete the Google storage bucket. However, I use an iframe to load a preview for a PDF, this preview indicates the following: '''AccessDeniedAccess denied.Anonymous caller does not have storage.objects.get access to the Google Cloud Storage object.''' If I use an tag and load the same file from the Google bucket it works completely fine. However, using the messes it up due to insufficient permissions. Keep in mind that the files can not be publicly available due to privacy. Moreover, I would like to use the tag due to the variety of content being displayed. As it sometimes might be a PDF or Video. ScreenshotThe preview of the file unavailable -
How to get a reference to the already loaded leaflet map in Djano's admin page using Django-leaflet
I'm trying to add markers to the leaflet map loaded in Django's admin pages with data retrieved from an ajax call. However I cannot get a reference to the map that I can use in my template used to override the Django admin template. If I load the page, open the console, and run the code below it works. The marker is added to the map. Console: var map = window['leafletmapid_location-map']; L.marker([40.3830621, -111.773658]).addTo(map); However if I include the exact same code in my template it doesn't work because it is not getting the reference to the map, and I can't figure out why. Template: {% extends "admin/change_form.html" %} {% load i18n admin_urls %} {% block content %}{{ block.super }} <script> var map = window['leafletmapid_location-map']; L.marker([40.3830621, -111.773658]).addTo(map); </script> {% endblock %} If I replace the entire script tag with the following I get undefined which I believe is the cause of the problem. Template: <script> console.log(window['leafletmapid_location-map']) </script> However if in change the template to the following I get the window object, and it shows it has the leafletmapid_location-map object available. Template: <script> console.log(window) </script> -
How can I deploy a django to app to heroku?
I am trying to deploy my django app to heroku. I have followed this tutorial word for word. After I have successfully deployed the application and open the app on the browser it says to me that there is an application error. It tells me to look at my logs.

Python/Django routing messed up when clicking a button
I am working through a basic django tutorial and I have become stuck. When the favorites button is clicked I am trying to redirect the user to reviews/favorite, which will then redirect to reviews/review_id, which is where they started. Instead, whenever I click the favorite button on the page it redirects me to reviews/reviews/review_id which fails. Interestingly enough if I remove the /reviews/ part from the form action in single-review.html then it routes me to /favorite, which fails because it doesnt exist, but when I put it back to reviews/favorite I go back to reviews/reviews/favorite as the routing. Anyone know what I am doing wrong?

Django model Foreign key serialization
In a django model, I want to custom the natural foreign key for the model to be serialized as it would be directly with the serializers.serialize function (and not just an array or tuple). Then, what prevents me doing this? class Player(models.Model): def natural_key(self): player = serializers.serialize('json',[self],use_natural_foreign_keys=True) return json.loads(player)[0] Is there a better way to return a json model for a foreign key of this form: { model: "play.player", pk: "72026f4d-3c74-4edd-9f88-5ab8330218b1", fields: {…} } -
Django filter - is DateTimeField filled
to my model I added a simply DateTimeField: expired = models.DateTimeField(default=None) . The value of the field can be either None or a Datetime. I'd like to filter for objects where the expired is filled with any datum, however I'm struggling to find the right filter. I think I tried all the combinations of filter / exclude and expired__isnull=True / expired=None, but I never get back the exact number. What's the right way to filter if the field has a DateTime in it, or not? Django: 1.11.16 Thanks. -
Django Middleware does not modify request in tests
I am trying to create test class for my custom middleware. The project is using Django REST framework. Middleware class works fine when server is running, but when I run test it behaves not quite as I would expect it to do. Maybe I misunderstood something, as I am quite new to testing in Django. my_middleware.py: class FX: a = False b = None c = '' def __init__(self) -> None: pass def __str__(self): return 'fx ok' class MyMiddleware(object): def __init__(self, get_response): self.get_response = get_response def __call__(self, request): request.fx = FX() response = self.get_response(request) print('done') return response views.py: class TestView(APIView): def get(self, request, format=None): print('View ok') print('FX: ', request.fx) return Response({'result':'ok'}) tests.py: class TestMyMiddleware(APITestCase): @classmethod def setUpTestData(cls): pass def setUp(self): pass def test_fx(self): response = self.client.get(reverse('TestView'), content_type="application/json") request = response.request self.assertTrue(hasattr(request, 'fx')) The code above actually runs the middleware. It prints "done" form the middleware call, then prints 'View ok' and also prints FX instance. However request.fx is not available in the test_fx method, thus giving assertion failure: self.assertTrue(hasattr(request, 'fx')) AssertionError: False is not true Any idea what I might be doing wrong? -
Django-import-export update_or_create with UniqueConstraint

I tried adding this to my ProfileResource: def before_import_row(self, row, row_number=None, **kwargs): try: self.email = row["email"] except Exception as e: self.email = None try: self.investor_type = row["investor_type"] except Exception as e: self.investor_type = None def after_import_instance(self, instance, new, row_number=None, **kwargs): """ Create any missing Profile entries prior to importing rows.

How to update Wagtail static files, they stopped working when I used STATIC_DIRS
I'm trying to update Wagtail from version 2.8 to the latest 2.15. Also, I had to update from Django 3.0 to 3.2. However, I noticed that when I use STATICFILES_DIRS, the style of the Wagtail admin (2.15) gets distorted as if it's using the files from the old version (2.8). PROJECT_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) BASE_DIR = os.path.dirname(PROJECT_DIR) ... STATICFILES_FINDERS = [ 'django.contrib.staticfiles.finders.FileSystemFinder', 'django.contrib.staticfiles.finders.AppDirectoriesFinder', ] STATICFILES_DIRS = [os.path.join(PROJECT_DIR, 'static'),] STATICFILES_STORAGE = 'django.contrib.staticfiles.storage.ManifestStaticFilesStorage' STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' Conversely, when I delete the STATICFILES_DIRS, the style on the Wagtail admin gets fixed, but the all the style on my project its gone. I already checked and it's not the cache. I tried that several times, different browsers, etc. -

Whitenoise Not Working when DEBUG = FALSE - Django - Hosting Static Files
I am running a Django website and it's about to go into production. I am now at the point where I need to set DEBUG = False in my settings.py file. I am getting the typical 500 errors because I have static files that are being hosted locally. I am working on getting Whitenoise to work to host my static files so I can move on with DEBUG = False. I have followed a lot of documentation and a lot of tutorials and think all of my configurations are all set but I am still getting the same error. When DEBUG = False I am still getting 500 errors on my production pages that have static files. Also when I inspect any static files on the page when DEBUG = True the URL has not changed at all.
