Better way to query from multiple tables using django ORM
I have the following models: class Client(BaseModel): #other fields engineers = models.ManyToManyField(Engineer, null = True, blank = True, related_name='clients') class OrganizationMember(MPTTModel): designation = models.CharField(max_length = 100, blank = True) user = models.OneToOneField(User, on_delete=models.CASCADE) parent = TreeForeignKey('self', null=True, blank=True, related_name='children', on_delete=models.SET_NULL) Now I would like to get all engineers of a client instance and check if each engineer has an organizationmember instance or not. Then if they belong to some organization then I should get_ancestors of that organizationmember and then the users. If they do not have any organizationmember then just get the user of that engineer instance. For this I have written a method in Client model as below: class Client(BaseModel): def get_users_from_engineers(self): users_in_organization = [] users_outside_organization = [] engineers = self.engineers.all() if engineers: for engineer in engineers: user = engineer.user if hasattr(user, "organizationmember"): users_in_organization += [orgmember.user for orgmember in user.organizationmember.get_ancestors(include_self=True)] else: users_outside_organization.append(user) Now this code is working correctly but I am sure that I can use django filters here instead of two for loops and optimize this code. But I do not know how. For eg: OrganizationMember.objects.filter(user__engineer__in=self.engineers.all()) can be used to get all the organizationmembers of the engineers of that particular client instance. But I need the users of … -

For Entering the Exam_Score, first the user Should query the database using a form to get the right set of students and then enter the scores. I got the first part but I don't know how to solve the last part which is entering the students scores. This is the form: forms.py class CourseMemberForm(forms.Form): course = forms.CharField(max_length=50) department = forms.CharField(max_length=10) year = forms.IntegerField() semester = forms.IntegerField() This is the view: def ent_exmscr(request): form_fields = ['course', 'department', 'semester', 'year'] form = CourseMembersForm() if request.method == 'POST': form = CourseMembersForm(request.POST) if form.is_valid(): course = form.cleaned_data["course"] dep = form.cleaned_data["department"] smstr = form.cleaned_data["semester"] yr = form.cleaned_data["year"] crs = Course.objects.get(name=course) stdnts = Members.objects.filter(department=dep, semester=smstr, course=crs.id, year=yr) return render(request, 'office/exm_mrk.html', {'stdnts': stdnts}) else: return form return render(request, 'office/exmrk_form.html', {'form': form}) The above view queries the database based on parameters entered by the user and returns a list of students in a new template. So how can I enter the students' scores in the new template? Thanks in advance. This is the model: dep_choices=[ ('MIS','MIS'), ('BBA','BBA') ] course = models.ForeignKey(Course, null=True, on_delete=models.SET_NULL) student … -

What is the use of False in delete() function in django?
I'm working on code refactoring of django project which was like 4 years old and came across a syntax which confused me. They passed a boolean parameter False to django ORM like object.delete(False). I checked the docs for delete() function in django ORM. But couldn't find False parameter to it. And there is no method overriding in Django Model for delete() method. What is this False parameter for? -
How to get value of model method in Django Rest Framework?
So basically I have a django model that has a ManyToManyField of friends and two methods that run on it. Here are my files: Models.py: from django.db import models from django.contrib.auth.models import User class Profile(models.Model): first_name = models.CharField(max_length=50, blank=True) last_name = models.CharField(max_length=50, blank=True) user = models.OneToOneField(User, on_delete=models.CASCADE) friends = models.ManyToManyField(User, blank=True, related_name='friends') def friends_list(self): return self.friends.all() def number_of_friends(self): return self.friends.all().count() Serialzers.py: from rest_framework import serializers from .models import Profile class ProfileSerializer(serializers.ModelSerializer): class Meta: model = Profile fields = '__all__' Views.py: from rest_framework import viewsets, permissions from .models import Profile from .serializers import ProfileSerializer class ProfileViewSet(viewsets.ModelViewSet): queryset = Profile.objects.all() permission_classes = [ permissions.AllowAny ] serializer_class = ProfileSerializer The issue is that in the Api, the return values of the method aren't there. The friends_list method for example is supposed to return a list of friends you have and even though this does work in a traditional django project, the Django Rest Framework is not showing any value for this method. How can I fix this and get the return values for both methods to show up in the api?
