Django Rest Framework API POST receiving status code 200 instead 201

What is the most efficient way to store images feature vector?
I'm working on project that needs to deal with images, I extract their feature vector instantly when any image uploaded then I store the feature vectors in MySQL database as text per each image. Also I'm using django framework. def search_images_by_features(query_image: ImageFieldFile, images): featured_images = [ (calculate_similarity(load_features_from_str(image.features), get_image_feature(query_image)), image.item) for image in images if image.features is not None] ... But looping on each image isn't a big deal as it takes more time as images increase. Also my feature vector in database stored like that: 0.0010601664,0.0003533888,0.8969008,0.0014135552,... Also is there a way to make MySQL database engine calculate similarity from feature vectors? -

Why is the "on_update" option not present in Django Relationship fields?
I'm using Django 3.0 + MariaDB. I've created a models.py from an existent database with the "python manage.py inspectdb > models.py" command. I need now to set the options for the Foreign Keys. As you know in a database you can have multiple options for the Foreign Keys: the first classic is "ON_DELETE" and the second is 'ON_UPDATE' (You can even have more options in PostgreSQL). In Django, there is just an "on_delete", but no "on_update" option, what I found very surprising. I found nothing on the official documentation about this. Neither on some old posts with the same question, the responses were not conclusive and focused on the "on_delete". I'm asking about the "ON_UPDATE' option, nothing else. So, where is this option, or why is it not present in Django's ORM ? -

Django DateTimeField Doesn't Translate Time While Saving To Db
I have a Django model named "Event". class Event(models.Model): screen_name=models.CharField(max_length=256) description=models.TextField(max_length=512) date_time=models.DateTimeField() Everyhing looks nice, and I see the datetime picker on the Admin interface. My settings.py has the following: LANGUAGE_CODE = 'en-us' TIME_ZONE = 'UTC' USE_I18N = True USE_L10N = True USE_TZ = True My question is: My browser time is 2 hours ahead of the server time. When I pick a date and time (e.g 05:00:00), it is saved in the Db as 05:00:00. The Db record does not keep record of the timezone. As far as I know, Django considers DB records as UTC strings. I want it to be translated from my timezone (GMT +2) to (UTC) before saving it to the Db. (e.g 03:00:00) What am I doing wrong? I would be glad if you help me solve this. Thanks! -
Login Authentication - Django
I am having a really hard time trying to understand the following: I am new to web development and i use django for my project, i already added the @login_required decorator to the views that need an authenticated user to show up, everyhting works fine until there, but when i hit the logout button which redirects me to the index page of the webapp and i hit the back arrow of the navigator again, everything that must need to show up only if there is a user authenticated shows up again, i don't think that is the correct behavior of django or what am i doing wrong? Is there any other decorator or function call i must do so that this doesnt happen anymore? -

Writing an efficient node.all_siblings_leaf() method for django-mptt
I have a tagging system, where the tags exist in a hierarchy. I've used django-mptt to build the Tag model. I want to display a group of tags differently if every sibling in the group is a leaf node. To do this, I want a model method called all_siblings_leaf(). Here's my first take on that method: def all_siblings_leaf(self): """Return True if all siblings, including self, are leaf nodes.""" siblings = self.get_siblings() return all([sibling.is_leaf_node() for sibling in siblings]) This works, but it's one trip to the db for the get_siblings() call. When I want to call all_siblings_leaf(), I've already queried for all the tags I want to use. Using this method repeatedly with a set of several hundred tags means several hundred new db calls. Since I already have all the tags, I feel like I should be able to get the information about leaf nodes without any additional trips to the db. Here's what I've come up with: def all_siblings_leaf(self, all_tags): """Return True if all siblings including self are leaf nodes. all_tags should be a queryset that used select_related('parent') """ if self.level == 0: siblings = [t for t in all_tags if t.level == 0] else: siblings = [t for … -

Delete posts on profile django
I have been working on a project and one of the functions that it has it to delete posts, when in the imagelist view, I am able to delete those posts but when I am in the profile view which shows the user's posts when I try to delete it, a 404 error page not found shows up.

Django Database Structure for Users in Teams
This is probably a very easy question. I want to create the following functionality in django. Someone can create a team and add people to the team. So, at any point, there could be several teams with several users in them. The team data structure has CRUD capabilities. Kind of like github teams. What would be the best database structure for this? I know there are many ways - so what are the advantages and disadvantages of each way?! New to this so really appreciate any questions. -
