UpdateView post() returns success message even if user tries to submit disabled form field
I've made a custom django form and mark email field as disabled. If someone tries to remove readonly attribute from browser's developer console and submits the form, email isn't updated but it doesn't show error message either it just shows success_message I've in my Update view. Is there any way to handle this and return error message instead of success. Below are the code snippets class ProfileView(AdminRequiredMixin, SuccessMessageMixin, UpdateView): template_name = '/profile.html' form_class = UpdateProfileForm success_message = 'Profile Updated Successfully' and the UpdateProfileForm class UpdateProfileForm(forms.ModelForm): email = forms.CharField(disabled=True) class Meta: model = User fields = ['image', 'name', 'role', 'email'] Now i want if user tries to submit the email forcefully, it shows an error message that email isn't editable or so. -
LookupError: App 'app' doesn't have a 'CustomUser' model
So I added the following line in my settings.py: AUTH_USER_MODEL = 'app.CustomUser' And I got the error: LookupError: App 'app' doesn't have a 'CustomUser' model. The last line in error is: django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'app.CustomUser' that has not been installed Here is my CustomerUser class in app/models.py: from django.db import models from django.contrib.auth.models import User from django.contrib.auth.models import AbstractUser from django.utils import timezone class CustomUser(AbstractUser): user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='CustomUser') name = models.CharField(max_length=500) phone = models.CharField(max_length=30) email = models.CharField(max_length=500) class Meta: abstract = True I get this error while trying to run makemigrations.

creating pandas dataframe from large list of records: how to make more efficient?
I am creating an epidemiological model which takes inputs and produces outputs. A standard output is a python dictionary with the following information { 'Location': 'Australia', 'Age group': '1 to 4', 'Sex': 'm', 'Cancer': 'cervical', 'Stage': 'stage IV', 'Coverage': 'Covered', 'Year of cohort': 2022, 'Year': 2025, 'Mortality': 0.0 } However, the current model produces 330,000 dictionaries which look like this. I'd like to create a dashboard using this information, which maintains the data in each entry. My first thought was to create the dataframe iteratively as follows: pd.DataFrame([x for x in huge_list_of_dictionaries], index=[0]) This produces the intended result, but takes several minutes to aggregate the data (using my personal computer, intel i7, nothing fancy). The hope is that this data can be used fairly quickly in a webapp using django, so reducing the speed is essential. I have had two thoughts about quicker solutions, Encode the strings as integers (e.g. male sex = 0), then remap the data once in the dataframe, or even when plots are generated. Have an intermediary step where the relevant data is selected (e.g. only prostate cancer) and only return this data Is there a more obvious solution that I am missing? -

Django Multiple Types of Users, one base usertype?
I am attempting to create a food delivery app clone. Which has two types of users Restaurant User and Customers. I want the restaurant user to be able to also be customers, using the same login info. This is how my models are setup right now: class Restaurant(models.Model): user_name = models.OneToOneField(User, on_delete=models.CASCADE, related_name='restaurant') full_name = models.CharField(max_length=500) phone = models.CharField(max_length=500) employee_id = models.CharField(max_length=500) class Customer(models.Model): user_name = models.OneToOneField(User, on_delete=models.CASCADE, related_name='customer') full_name = models.CharField(max_length=500) email = models.CharField(max_length=500) avatar = models.CharField(max_length=500) phone = models.CharField(max_length=500) address = models.CharField(max_length=500) I don't believe this works as intended. Would it be better to create a base usertype, for login and shared information, like user_name, full_name, phone? I created the following for that purpose: class CustomUser(AbstractUser): user_name = models.OneToOneField(User, on_delete=models.CASCADE, related_name='CustomUser') full_name = models.CharField(max_length=500) phone = models.CharField(max_length=30) But I'm not sure how to connect this between the other user models. Or if this is even the proper way to do it. So how can I achieve what I am trying to do, what would my models look like? -

django.db.utils.DatabaseError when updating upvotes of a post

Is modifying Django urlconf via set_urlconf and request.urlconf in a middleware safe?
I am changing the default urlconf in a middleware based on the requested hostname and it's working as expected during development, however I am concerned about racing/threads as I am modifying a Django setting at runtime! My concern is that Django would confuse the urlconfs with many concurrent requests. Is that a valid concern? -

Set a reverse foreignkey relationship in django without saving
if you have an instance of a django object, you can set a field and if you don't save it, it goes away. if you have a foreignkey relationship and you use set, clear, etc. the change you made is immediately written to the db. this makes sense, but is there a way not to do this. As in to temporarily modify the relationship objects, similar to what you can do for a charfield, etc. https://docs.djangoproject.com/en/3.1/topics/db/examples/many_to_many/ class Foo(model): name = charfield() class Bar(model): name = charfield() foo = Foreignkey(Foo, related_name="bars", null=True) bar1 = Bar.objects.create(name="bar1") bar2 = Bar.objects.create(name="bar2") foo = Foo.objects.create(id=1, name="dog") foo.bars.add(bar1) foo.bars.add(bar2) foo.name >> "dog" foo.name = "cat" foo.name >> "cat" len(foo.bars.all()) >> 2 foo.bars.clear() len(foo.bars.all()) >> 0 foo1 = Foo.objects.get(id=1) foo1.name >> "dog" len(foo1.bars.all()) >> 0. ---->>>> i want this to remain 2 -
modify the @login_required Decorator in Django to do authentication Role wise - Django, Python
I am working on a project in Django 3.1.2, here I have several models and views, and I have three entities admin, designer and customer.

How do I sort a Django queryset by frequency of occurance from a list and ensure the remaining objects follow?
I have a Django application running Django 3+ and Python 3.8+. I am trying to fill the front page of my site with relevant accounts to the user currently logged in. I have a list of common tags (belonging to the logged in user), let's call this: common_tags=['tag1','tag2','tag3'] This list can vary in length. My goal: I need to be able to query all my users and filter it in such a way that I get an ordered queryset where the users who have the most common_tags as their tags come up on top. That set of people need to be sorted by who has more tags in common (not based on how many of each tag they have, just the common occurrences with logged in user). This same query set should also contain the remaining users who do not have any of the common tags. Lastly, this queryset should not have any repeats. So far I have: relevant_accounts= User.objects.all()\ .annotate(count_resources=Count('resources')).order_by('-count_resources')\ .order_by(Case(When(resources__tags__name__in=common_tags, then=0),default=1, output_field=FloatField())) This appears to work, but I get repeated values. Running .distinct() does not resolve the issue. Edit: Sample Input/Output User A: Tags = ['A','A','B','C'] User B: Tags = ['A','B','B','C'] User C: Tags = ['A','B','B','B'] Sample User … -

Django - Cannot pass id of Django form to javascript variable
So I read the django documentation and a django form field id should have the format id_(form field name), but when I try to reference this id when assigning the form field to a javascript variable it returns null. To test this, I used auto_id to make sure the id I used in javascript matches the field id I am trying to reference and it does. Additionally, I passed another html element ("testid") to my javascript to make sure it works with the rest of the elements in the template and it does.

Django Heroku not displaying all images when DEBUG=False
I have deployed my app on Heroku and all works fine when DEBUG=True however when I set this to False some of my images do not show up.
