Django override save method for resize image only works forn one function. Why is this happening?
I got those two functions in my Model but only the cover_photo one is working. class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, blank=True, null=True) profile_picture = models.ImageField(upload_to='users/profile_pictures', blank=True, null=True) cover_photo = models.ImageField(upload_to='users/cover_photos', blank=True, null=True) ... def save(self, *args, **kwargs): super().save(*args, **kwargs) if self.profile_picture: img = Image.open(self.profile_picture.path) if img.height > 50 or img.width > 50: new_height = 100 new_width = int(new_height / img.height * img.width) img = img.resize((new_width, new_height)) img.save(self.profile_picture.path) def save(self, *args, **kwargs): super().save(*args, **kwargs) if self.cover_photo: img = Image.open(self.cover_photo.path) if img.width > 100 or img.height > 100: new_width = 600 new_height = int(new_width / img.width * img.width) img = img.resize((new_height, new_width)) img.save(self.cover_photo.path) If i swap then, only the profile_picture works but the other one stops. Does any one have any idea why this happens? Is there a way to make both works. Thank you very much! -
I have 69 Heads in git. I don't see recent commits on reflog. How can I find recent commits?
My Problem in Git Bash is that the most recent version that I can find is Head@{0} and is 2 months old. When running recent commits the feed back stated that everything was up to date. Is there anywhere my recent commits might be? I looked into the history and cannot find commits that I made just last night. I had been trying git push to send my commits to Github but it did not work the last couple of times I tried. I pulled the file from Github and now my program is as it was 2 months ago. I have 69 Heads and cannot find any sha that contains new versions. I tried the Github desktop program and cannot find any recent commits there either. I did not have any branches going at the time. -
Django DRF on kubernetes and max concurrent requests tuning
I migrated a Django 4 DRF app running in a Docker container to kubernetes on OVH and I cannot figure out how to determine the max concurrent requests supported by a single replica (to later be able to increase that with more replicas/nodes) My configuration is the following 1 node : 16 core 3ghz / 60GB RAM Django / gunicorn gunicorn api.wsgi --workers=64 --timeout=900 --limit-request-line=0 --bind 0.0.0.0:8000 I first tried with a simple DRF function (no DB / no model / no serializer). Later it will database queries and a CPU demanding function. class BenchView(APIView): permission_classes = (AllowAny,) def get(self, request, format=None): return Response({"bench":"bench"},status=200) I would expect that with 16 cores, a such simple function and 64 workers I get the same response time for one request that for 64 requests launched in parallel but I get this kind of result using apache bench for example ab -n 64 -c 1 'https://server/api/bench/' 50% 96 66% 98 75% 99 80% 100 90% 103 95% 111 98% 120 99% 121 100% 121 (longest request) ab -n 64 -c 16 'https://server/api/bench/' 50% 127 66% 130 75% 133 80% 137 90% 141 95% 142 98% 145 99% 150 100% 150 (longest request) ab -n … -

Django admin - building HTML page with 2,000 inlines is slow, while DB query is fast
Question in short: I have a model admin with tabular inlines. There are around 2,000 related records. Fetching them from the database takes only 1 ms, but then it takes 4-5 seconds to render them into an HTML page. What can I do to speed this up?

Django adds quotes in template to each TextField. How to get rid of them?
I have some TextFields in my MySQL Database, like: body = models.TextField(default = 'initial') When I call out it in my template doing this: <p class = "service_description"> {{ post.body }} </p> I get this: <p class = "service_description"> " This is the text from the database, but it is with 2 quotes and 2 spaces around itself. " </p> As you can see, it adds excess quotes around the text. I tried to add |safe to the post.body it doesn't help. I also tried to add {% autoescape off %} {{ post.body }} {% endautoescape %} it doesn't help as well. Please let me know, why do I get these excess quotes and how to remove them correctly without slicing? Thanks. -

Unable to expose docker container port to another container

How to Store file_paths for fast matching queries?
I am trying to store the file path of all files in a BUCKET. In my case a bucket can have millions of files. I have to display that folder structure in a UI for navigation. storage_folder: - bucket_1 - bucket_files.txt - bucket_metadata.txt - bucket_2 - bucket_files.txt - bucket_metadata.txt # bucket_file.txt contains folder1/sub_folder1/file1.txt folder1/sub_folder1/file2.zip folder1/sub_folder2/file1.txt folder2/..... .... .... Current approach: I will create a .txt file corresponding to each BUCKET which will contain absolute paths of each file in that bucket. Then whenever a query comes the whole file goes through lots of string matching which is really slow. What I want: I want to store those files in a tree based structure for optimized queries. Is there any solution for this? for context I am building my backend in Django. -

Django css and javascript app not served in production
I have a django project which in development mode css are loaded just fine but not in production. In my settings.py file I've set these trhee variables STATIC_ROOT = BASE_DIR / 'staticfiles/' STATIC_URL = 'static/' STATICFILES_DIRS = [ BASE_DIR / 'static', ] I also set DEBUG = False When I run python manage.py collectstatic command the staticfiles folder receives the files properly. I created a static folder in the root of the project to install bootstrap there, again, in developent runs just fine. I'm using Apache server throug XAMPP becasuse I'm on Windows. the configuration for the project is next: `LoadFile "C:/Python310/python310.dll" LoadModule wsgi_module "C:/Users/life/.virtualenvs/outgoing-qJCH8A9k/lib/site-packages/mod_wsgi/server/mod_wsgi.cp310-win_amd64.pyd" WSGIPythonHome "C:/Users/life/.virtualenvs/outgoing-qJCH8A9k" WSGIScriptAlias /outgoing "D:/DEV/PYTHON/GASTOS/software/outgoing/project/wsgi.py" application-group=%{GLOBAL} WSGIPythonPath "D:/DEV/PYTHON/GASTOS/software/outgoing" <Directory "D:/DEV/PYTHON/GASTOS/software/outgoing/project"> Require all granted Alias /static/ "D:/DEV/PYTHON/GASTOS/software/outgoing/staticfiles/" <Directory "D:/DEV/PYTHON/GASTOS/software/outgoing/staticfiles"> Require all granted ` The point is, the app load well but without the bootstrap css and javascript files. Also the browser console tells this. `Refused to apply style from 'http://localhost/outgoing/static/node_modules/bootstrap/dist/css/bootstrap.min.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled. GET http://localhost/outgoing/static/node_modules/bootstrap/dist/js/bootstrap.bundle.min.js` Help please. -
