Is it wise to construct a custom string (combination of entity, year and alphanumeric) to have as a primary key for a postgres database in Django?
I'm working on creating a Django backend for an application and I want the primary key of our entities to fulfil certain criteria. First criteria is that it is always 10 characters long so that it is easy to read and share verbally if needed. Second criteria is that it always follows the same format:- First 2 characters => Code for the entity (for example "US" is for User records, "TO" is for topics, "BO" for books etc.) so that anyone can easily say what a certain ID is for Second 2 characters => Year of the date of creation ('24', '23 etc.) Remaining 6 characters are randomly generated alphanumeric characters I've written the following code to generate the id:- def auto_increment_id(): alphanumeric_chars = string.ascii_letters + string.digits last_chars = ''.join(random.choice(alphanumeric_chars) for _ in range(6)) user_id = 'US' + str(datetime.date.today().year)[2:] + str(last_chars) return user_id And I have it setup in the user model like this class User(models.Model): id = models.CharField(max_length=10, primary_key=True, default=auto_increment_id, editable=False) My question is, will this lead to performance issues or other issues as we scale up? Is this a wise setup? -

Connecting an old MySQL server to the latest Django installation
I'm making a Django project that connects to an external MySQL database for a college project. The problem is that the database is outdated, and I keep getting the error message, "MySQL 8.0.11 or later is required (found 5.6.40)." I cannot update the database server and I would like to keep using the latest version of Django. If I were to create a middleware to convert the response from the database to a format readable to the Django 5.0.1, what would be the topics I would need to learn? I added the external database to the settings.py along with the main database. I also used connections from django.db to make queries so I would not have to add the entire database to models.py. -

Large number of rejected connections in memcached using django

Module not found error with Django Channels
I'm completely new to using channels, but have tried two separate installations, and setups to just get a basic version of channels running and am encountering a small issue. I'm assuming I'm probably just missing a small thing, but I cannot figure it out. The error is at handshake error I'll also show the current file structure, as well as the files that I've actually made modifications to. asgi.py settings.py settings.py consumers.py consumers.py routing.py Originally, in settings.py having ASGI_APPLICATION set as mysite.asgi.application was resulting in an error so I changed that to mysite.settings and it seemed to work correctly when starting. However, on handshake now this issue occurs, so I feel like that could potentially contribute to it. I've tried on different projects and both encounter this issue. -

django-how to upload image using ImageField in a model form?
My form doesn't save the uploaded image in the path given, my code: models.py: class MyClass(models.Model): user = models.OneToOneField(SomeClass, on_delete=models.CASCADE) address_line_1 = models.CharField(blank=True, max_length=100) address_line_2 = models.CharField(blank=True, max_length=100) profile_picture = models.ImageField(blank=True, upload_to='static/zzz/xxx/') forms.py class edit_profile_form(forms.Form): profile_picture = forms.ImageField(label='Avatar',widget=forms.FileInput( attrs={ 'class': 'form-control input_data', 'placeholder': 'Upload',})) views.py def validate_edit_profile(request): template = loader.get_template('account/edit_.html') user_form = edit_profile_form(request.POST,request.FILES) userprofile = EcomCustomerProfile.objects.get(user_id=request.user.id) #if user submit if request.POST: if user_form.is_valid(): # get the data first_name = user_form.cleaned_data['first_name'] last_name = user_form.cleaned_data['last_name'] phone = user_form.cleaned_data['phone'] profile_picture = user_form.cleaned_data['profile_picture'] #change db get_user = EcomCustomer.objects.get(id = request.user.id) get_user.first_name = first_name get_user.last_name = last_name get_user.phone = phone get_user.profile_picture = profile_picture user_form.save() get_user.save() return HttpResponse(template.render({'userprofile':userprofile}, request)) I'm using two forms: one for text, the other for uploading the image. But it doesn't upload anything. What's the problem ? -
