I am using Django and I want a field for URLs I know there is a URLField in Django but I want that field to be a charfield and I don't want users to submit anything other than URL in that charfield take a look at my models.py: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) email = models.EmailField(max_length=500, blank=True, null=True) social_github = models.CharField(max_length=200, blank=True, null=True) social_twitter = models.CharField(max_length=200, blank=True, null=True) social_linkedin = models.CharField(max_length=200, blank=True, null=True) social_youtube = models.CharField(max_length=200, blank=True, null=True) social_website = models.CharField(max_length=200, blank=True, null=True) created = models.DateTimeField(auto_now_add=True) id = models.UUIDField( default=uuid.uuid4, unique=True, primary_key=True, editable=False) def __str__(self): return str(self.username) Please answer how can I make a char field behave like a URL field -
Add more than 1 folder (network path) to static files with Django on IIS
I have a django website deployed on an IIS Server. in it, I have 2 different network paths I need to access via static STATICFILES_DIRS = [ "//server1/Shared1/folder/", "//Server2/folder2/", ] Now, currently my IIS has a static virtual directory that is set to "server1" this allows me to work with all the files I have in that shared network drive and opertate properly. The issue comes when I try to work with any files in the "server2" I don't know how to add it. I understand that exists something called "static root" but for that I need to do a "collect static" in this case, I can't do a collect static since both servers have over 60gb of data that I need to access. Is there a way I'm not seeing for adding this second server to be able to be used via IIS? -
How to apply multiple filters in a Django query without knowing if some filters are null or not
Let's say we have the following filters: filter1 = request.GET.get("blabla") filter2 = request.GET.get("blabla") filter3 = request.GET.get("blabla") filter4 = request.GET.get("blabla") filter5 = request.GET.get("blabla") filter6 = request.GET.get("blabla") Let's say we have the following query: user_projects = Project.objects.filter(element1=filter1, element2=filter2, element3=filter3, element4=filter4, element5=filter5, element6=filter6).distinct().values("id", "name", "customer_id", "dev_status", "manager_id", "total_billable") Some of the filters might be of type None (depends on the request) I would like to create a dynamic query that based on whether the filter exists or not, executes the query only with the non-null filters. Let's say for example filters 1, 2, and 3 have values, but filters 4, 5, and 6 are empty/null/None. Expected query: user_projects = Project.objects.filter(element1=filter1, element2=filter2, element3=filter3).distinct().values("id", "name", "customer_id", "dev_status", "manager_id", "total_billable") What I've tried: if filter1 is None or filter1.strip() == "": filter1 = "" elif is_valid_queryparam(filter1): user_projects = Project.objects.filter(element1=filter1).distinct().values("id", "name", "customer_id", "dev_status", "manager_id", "total_billable") And it works, but only for one filter, if I want that for 6 or N filters, it's extremely inefficient to execute multiple queries. Is it possible to achieve the desired result with a simple query? -

Django CBV form submission returned JSON is displayed as a new page
I am using Django 3.2 I am creating a simple newsletter subscription form.

Why are django-q scheduled tasks delayed randomly?
I'm finding that django-q is not executing tasks I schedule on time. There can be delays of several seconds to almost a minute. I schedule a task like so: from django.utils import timezone from django_q.models import Schedule def schedule_auction_deadlines(self): now = timezone.now() if self.deadline: name = "end_phase_%d" % self.id Schedule.objects.filter(name=name).delete() if now < self.deadline: Schedule.objects.create(name=name, func="myapp.views.end_phase", args=str(self.id), next_run=self.deadline, schedule_type=Schedule.ONCE) And here is my configuration in the settings.py file: Q_CLUSTER = { 'name': 'myproj', 'label': 'Django Q', 'timeout': 30, 'catch_up': True, 'guard_cycle': 1, 'redis': os.environ.get('REDIS_URL', 'redis://localhost:6379'), } From the docs it seemed like guard_cycle might be relevant, but I've got it set at the minimum setting. What could be causing these delays? -

Offline Cache Web Application with Django
I have faced some problems with offline web application which used VueJS(frontend) and Django(Backend) with postgres database. Currently postgres database are installed on cloud while frontend and backend are on local computer, in order to avoid retrieve or update data every time from cloud, I have used cache in Django to store data temporary.

How to avoid sending error from a specific Python library to sentry?
I'm using django and logging errors to sentry via sentry_sdk. However, I do not want to log errors from specific library. For example, libraries such as elastic apm generate various errors(Like TransportException, ..., etc) depending on the state. import sentry_sdk from elasticapm.transport.exceptions import TransportException sentry_dsk.init( dsn='SENTRY_DSN', ignore_errors=[ TransportException() ] ) The example above is how to write down a specific error and ignore it. Is there a way to ignore errors that occur in a specific library other than this way? -

How to use 2 engines with the same database in Django?
Note: This question is NOT about using 2 databases. So I have been using timescaledb with my django project and my DATABASE portion in my settings.py file is something like this: DATABASES = { 'default': { 'ENGINE': 'timescale.db.backends.postgresql', 'NAME': os.getenv('DB_NAME'), 'USER' : os.getenv('DB_USER'), 'PASSWORD' : os.getenv('DB_PASSWORD'), 'HOST' : os.getenv('DB_HOST'), 'PORT' : os.getenv('DB_PORT'), }, } Now, I want to use postigs with the same database. Under the hood, i can just install the postgis extension to postgres but how should i configure the settings in django? All the documentation of using postgis suggests to use different settings for the 'ENGINE' property, but i have to use timescale too. This article shows it is possible to use both with single DB. But I am just not sure how to do it with django? -

""" so i have this view function, def simple_upload(request): if request.method == 'POST' and request.FILES['image']: file = request.FILES['image'] print(sys.getsizeof(file)) chunk_size = 0 dd = list(file.chunks(chunk_size=20000)) print(len(dd[0])) // this gives me some figures like the size of the image print('...') for chunk in list(file.chunks(chunk_size=10000)): chunk_size += sys.getsizeof(chunk) print(chunk_size) return redirect('index') return render(request, 'upload.html') generally, my expectation is that if the image is 50000bytes and i choose a chunk_size of 10000 the length of the generator should be 5. i dont know if i am missing something. -
How do i provide a default image for a django project
In my project, I want users to be able to create a post without an image and if they create it, the default dummy image would be there rather than it Beign blank In my models.py related_image = models.ImageField(default='defaultimg.jpg', upload_to='images/’, null=True) Now if I create a post in the admin section, it would put the default image but if I create it from the users point of view(the form), it does not upload or use the default image forms.py class BlogPostForm(forms.ModelForm): related_image = forms.ImageField(label='', required=False) views.py def uploadPost(request): form = BlogPostForm() if request.method == 'POST': form = BlogPostForm(request.POST, request.FILES) if form.is_valid(): form.save() return redirect('home') The problem is that when a user create a post, the related image would be empty but from the admin section, the default image would show. I want the default image when a user don't provide an image to be 'defaultimg.jpg' Thanks for your contribution -
