How to avoid FileNotFound Error in django model ImageField when file does not exist
I have a Django model which has ImageField img and I have thousands of rows in the db while I also know some of the images in the db do not exist in the directory. But its an existing project and I cant do anything on that for now while the clients produce the missing images later. But the issue is while retrieving a queryset without any reference or specific use of the image files, I get a FileNotFound error. This happens both in Django admin once I paginate to a page that contains one of the records with missing file and also in a ViewSet's queryset I try to create for frontend. And because I have not paginated the ViewSet queryset, I can't even test the endpoint without having the FileNotFound error. How to catch this error or avoid it? -

Django with Auth0
Currently learning about Auth0 and django. https://github.com/auth0-blog/django-feed-auth0/blob/main/feed/feed/urls.py I saw the URL pattern is like this urlpatterns = [ path('admin/', admin.site.urls), path('', include('feedapp.urls')), path('', include('social_django.urls')), ] From what i learned previously we should have 1 path('', views.xyz) as it will be redundant to have same url pointing to the different views unless we have put other input like int or str. But auth0 have same path with other views. Not really understand why is it okay for it to be like this? Hope you guys can explain to me. Thanks -

malloc error when migrate in Django using mySQL database
I'm using Django in VSCode and want to connect to the MySQL database, I've created the database in MySQL. When changing the database configuration from mysqlite to MySQL in settings.py, and do the migrate, the error pops up (in the picture below). Basically it says malloc error and asks me to set a breakpoint in malloc_error_break to debug. I have no idea of what's going on here. Anyone knows how to fix this error? The error message disappears once I changed the settings back to sqlite, it only happens when using MySQL. screenshot of error -
Django User Form Update with Groups

Passing a pk from one template to another
I am relearning django/python recently and trying to build an app to manage a season ticket draft between friends. I've become stuck while searching for this answer, could be my phrasing, but I'm trying to understand how to pass a value from one template to another. Here is an example of what I am doing. views.py def home_page_view(request): sessions = DraftSession.objects.filter(session_status="ACTIVE") return render(request, "index/index.html", { 'arena_mappings': ARENA_MAPPINGS, 'team_mappings': TEAM_MAPPINGS, 'sessions': sessions, }) index.html {% for session in sessions %} <tr> <td> {{ session.season_year }} </td> <td> {{ team_mappings|get_item:session.home_team }} </td> <td> {{ arena_mappings|get_item:session.home_team }} </td> <td> {{ session.create_date }} </td> <td> {{ session.session_owner }} </td> <td> <button type="button" class="btn btn-primary">Join Now!</button> </td> </tr> {% endfor %} Using the button in the last column I want the user to be able to go to a new page that has awareness of the row that was selected, my assumption is this would be passed in via the pk for the db row. I've setup the view, urls, etc; just lost on how to pass the selection on the the new page. Appreciate any help! -
django 3rd party API Event Loop?
I'm quite new to back-end development so please forgive my ignorance. I need to connect my Django backend to a 3rd party API to fetch live location data from GPS trackers. This needs to be done server side as it triggers other events, so it can't just be run in the browser. What's the best way to go about doing this please? So far I have thought of something like an event loop which calls the API every 60 seconds, but can I run this on a separate thread for example? Is that even the best thing to do? Is it possible to do something like a websocket form my backend to the 3rd party? What's the best way of keeping this data updated? Finally, how does a solution like this scale, what if I had 5,000 vehicle trackers which all needed updating? Any advice would be greatly appreciated. Thank you. -
Can't use assertTemplateUsed with unitest.TestCase
Please help, i'm fairly new to Django and not sure what's the best way to proceed with my unit-tests. So, i have a large django app, and it has dozens of views-methods, and the postgresql schemas get pretty complex. I've read that if I use "from django.test import TestCase" then the test database is flushed after running each unit-test. I wanted to prevent from flushing the db in between unit-tests within the same class, so i started using "from unittest import TestCase". That did the trick and the db is preserved in between unit-tests, but now the statement self.assertTemplateUsed(response, 'samplepage.html') gives me errors AttributeError: 'TestViews' object has no attribute 'assertTemplateUsed'. What can I do? Is there an alternative to 'assertTemplateUsed' that can be used with unittest.TestCase? Many thanks in advance! -

Django adding colon to the path out of nowhere
I have a pretty simple Django project based on the one from the tutorial that I am slowly morphing into my own app. It was working fine locally. I tried to deploy it to Heroku, so I made a few changes, but it was still working fine locally (I am still working on getting it to work on Heroku). But then I ran it once more and out of nowhere I am getting this error: Invalid argument: 'C:\\Users\\cusack\\PycharmProjects\\pythonProject\\website\\:\\index.html' So it is adding :\\ or \\: to the path for some reason. I have looked at settings.py, views.py, urls.py, and I can't find anywhere where I have told it to do this. My urls.py file looks (partially) like this: urlpatterns = [ path('', views.index, name='index'), path('images/random.png',views.my_image,name='randomImage'), path('admin/', admin.site.urls) ] The main page and admin both give this error, but 'images/random.png' works just fine. For the admin page, it is adding the extra :\\ before admin\\index.html. My views.py for this index is trivial: def index(request): return render(request, 'index.html') It happened when I was playing around with DEBUG and ALLOWED_HISTS, although changing them back to True and [] didn't seem to help. Any idea where this could be coming from? -

Python Django "surrogates not allowed" error on model.save() call when text includes emoji character
We are currently in the process of building a system that stores text in a PostgreSQL DB via Django. The data gets then extracted via PGSync to ElasticSearch. At the moment we have encountered the following issue in a testcase Error Message: UnicodeEncodeError: 'utf-8' codec can't encode characters in position 159-160: surrogates not allowed We identified the character that causes that issue. It is an emoji. The text itself is a mixture of Greek Characters, "English Characters" and as it seems emojis. The greek is not shown as greek, but instead in the \u form. Relevant Text that causes the issue: \u03bc\u03b5 Some English Text \ud83d\ude9b\n#SomeHashTag \ud83d\ude9b\ translates to this emoji:🚛 As it says here: https://python-list.python.narkive.com/aKjK4Jje/encoding-of-surrogate-code-points-to-utf-8 The definition of UTF-8 prohibits encoding character numbers between U+D800 and U+DFFF, which are reserved for use with the UTF-16 encoding form (as surrogate pairs) and do not directly represent characters. PostgreSQL has the following encodings: Default:UTF8 Collate:en_US.utf8 Ctype:en_US.utf8 Is this an utf8 issue? or specific to emoji? Is this a django or postgresql issue?
