Django ModelChoiceField queryset keeps returning same result regardless of input
I am trying to create a choicefield in a form which only contains those fields which relate to a previously selected option. So far on the site a user can select a parent option ( I Call discipline) and then submit at which time they are ask to select from a set of fields which are a subset of the selected discipline. Currently the pages all work and render except that on the second page I also get the same 6 results regardless of which discipline I select. I ran a print command and can see the objects.filter are returning the correct results but those results are not appearing in the drop down menu. I am stumped.... any suggestions? I have tried a number of online tutorials and checked several questions in stack exchange but nothing matches my issue. I am really confused how fieldOptions = Field.objects.filter(discipline_Main=discipline) print("The available fields are: %s" % fieldOptions) returns the correct results yet: field_name = forms.ModelChoiceField(queryset=Field.objects.filter(discipline_Main=disciplineID)) only ever shows the same 6 results. My Models are: class Discipline(models.Model): #This is the top level category ie: Math, physics, chemistry, biology, history, english, etc discipline_name = models.CharField(max_length=50) description_text = models.CharField(max_length=200) discipline_create_date = models.DateTimeField(default=datetime.now, blank=True) def __str__(self): … -

NGINX 502 bad gateway gunicorn timeout
502 bad gateway error pops up on saving data to the db. Once the user logs into the django app (OLE 7). Data is pulled regarding that user from ldap server and saved in my local db(postgres).

Why post_save signal is not working here?
I created a signal that creates profile when a user is created. Previously, the same code was working fine in other projects. Here, I don't know what I am doing wrong that it doesn't work and doesn't create profile for created users. This is the signal. @receiver(post_save, sender=User) def create_profile(sender, instance, created, **kwargs): print(instance) if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User) def save_profile(sender, instance, **kwargs): instance.profile.save() All the imports are done properly, and here I imported that in my app: class UsersConfig(AppConfig): name = 'users' def ready(self): import users.signals In case if you want to look at profile model: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.jpg', upload_to='profile_pics') def __str__(self): return "{} Profile".format(self.user.username) Since I created a signal, for all new created users it should add that default.jpg as default profile picture. But if I create a new user, login then go to profile page it shows something like this: and if I go to admin and add this profile picture manually it works fine. One final thing I added the following settings in urls.py as well: if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Please help me fix it, it has been 3 hours I tried all possible ways but couldn't make … -

django: Why can't I use __year lookup inside F() expression?
Suppose I have a model with two DateField's: class Event(models.Model): start_date = models.DateField() finish_date = models.DateField() This allows me to make queries that compare these fields, like ee=Event.objects.filter(finish_date=F('start_date')) and I can deal with the year of the date, like ee=Event.objects.filter(finish_date__year=2000) but when I try to use the same lookup __year inside F(), like this: ee=Event.objects.filter(finish_date__year=F('start_date__year')) , it fails: FieldError: Cannot resolve keyword 'year' into field. Join on 'start_date' not permitted. Is there any reason for such behavior, or does it look like a bug? I am using Django 1.11, and I see no such restricitions at https://docs.djangoproject.com/en/1.11/topics/db/queries/#using-f-expressions-in-filters . -
How to make triggers in backend with Django?
I am developing a personal project where teacher accounts can design their own multiple-choice exams for student accounts. One of the Exam class attributes is exam_time, an integer attribute which sets how many minutes are provided to the students when they are doing an exam. When a student starts running an exam, the Student class has two important fields, one is running_exam, which sets the exam id that the student is currently doing, and the other is exam_time, an integer that stores how many seconds are left for that student. def start_exam(request, exam_id): exam = Exam.objects.get(id=exam_id, students=Student.objects.get(email=request.user.email)) if exam: Student.objects.filter(email=request.user.email).update( doing_exam=exam.id, exam_time=exam.time*60, ) return etc... Now I need a way to trigger an event for each second to update the student's exam_time field, subtracting -1 for each second and checking if it is not in 0. Other way would be doing this with JavaScript but it is maybe very vulnerable since it is pure front-end. Suggestions? -

Apache not serving Django on 443 (aws)
I've got a django app I'm trying to serve over HTTPS and struggling. I'm not strong in Apache configs and trying to piece this together.

Custom User model error on changing password form through admin interface
Trying to set up custom user model on the start of django project, but i am facing a recurrent problem that i have only been able to patch, that now is affecting the changepassword of admin interface. On change password form submit, it crashes with error: AttributeError at /admin/custom_users/customuser/7/password/ 'NoneType' object has no attribute 'strip' on stack trace, i can see that the problem is that is_staff=NULL and is_superuser=NULL on the attempted query. I dont know why django passes this parameters as null on passwordchange since they are set to false on model and nowhere are they as fields on the CustomUserPassForm. Had this same issue on user change form, but after adding fieldsets to CustomUserAdmin(UserAdmin) class, i was able to edit a user.

I have some function based views in Django that are fairly simple, I followed the instructions here: https://docs.djangoproject.com/en/2.2/ref/contrib/admin/admindocs/ to set it up and it seems to work just fine for a view given by the Django REST Framework: rest_framework.authtoken.views.ObtainAuthToken As an example, this is what is generated in admindocs for the above view: /endpoint/auth View function: rest_framework.authtoken.views.ObtainAuthToken. Name: endpoint. But in the same namespace, the other function based views look like this: /endpoint/config View function: endpoint.views.WrappedAPIView. Name: endpoint. All of the other function views have the above endpoint.views.WrappedAPIView listed as the view function, and when I click that I obviously get a 404 because that is incorrect and doesn't exist as far as I can tell. The documentation I followed seems to indicate that function based views should work with admindocs, so I'm just confused on why they're not getting picked up. Thanks!! -
Django query: Sort objects by the number of occurrences of a value?
I'm trying to use Django to return a list of objects with duplicate values, sorted from most-duplicated to least-duplicated. For example, let's say I have the following model: class Person(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) name = models.CharField(max_length=128) I want to return a list of Persons, sorted from those with the most common name to those with the least common name. I know that I can use values and annotate to create a sorted list of name values like this: Person.values('name').annotate(Count('id')).order_by('id__count') But I don't want a list of names; I want a list of Person objects. Is there a way to accomplish this? -
is it possible to search two fields with one passed in reference django rest framework
I have a django rest framework project. I have a friend models which has a friender and friended model. the friender is a foreign key for the user which contains a username and friended is a char field that is going to be a username. I have a username passed in through the url that calls the serialize. I want it to be used to search through both fields and see if any records contain username for friender and friended. Would it be better to set both of the as charfields and store usernames in both or is there an easy way to seach both fields and combine the results... right now it checks the friended... i want to to check friended and friender.username here is my code: models: class Friend(models.Model): friender = models.ForeignKey(User, on_delete=models.CASCADE) friended = models.CharField(max_length=50) status = models.SmallIntegerField() blocked = models.BooleanField(default=False) favorite = models.BooleanField(default=False) created = models.DateTimeField(auto_now_add=True) def __str__(self): return self.friender.username + self.friended serializer: class FriendSerializer(serializers.ModelSerializer): class Meta: model = Friend fields = ( 'friender', 'friended', 'status', 'blocked', 'favorite', ) depth=2 views: from users.models import Friend from ..serializers import FriendSerializer from rest_framework import viewsets class FriendViewSet(viewsets.ModelViewSet): queryset = Friend.objects.all() lookup_field = 'friended' serializer_class = FriendSerializer -
