How to inherit a model from 2 classes that are being inherited from same parent class django?
I have the following models: class Grade(models.Model): grade = models.CharField(max_length=255, unique=True) class Student(models.Model): class Meta: unique_together = ("rollno", "grade") name = models.CharField(max_length=255) grade = models.ForeignKey(Grade,related_name='StudentList', on_delete=models.CASCADE) rollno = models.BigIntegerField(unique = True) class GradeTotal(models.Model): grade = models.ForeignKey(Grade, related_name='GradeMarks', on_delete=models.CASCADE) average = models.IntegerField() total = models.IntegerField() class StudentTotal(models.Model): rollno = models.ForeignKey(Student, related_name='StudentMarks', on_delete=models.CASCADE) gradeno = models.ForeignKey(GradeTotal, related_name='Fromgrade', on_delete=models.CASCADE) marks = models.IntegerField() I am using the model Grade to create GradeTotal and then StudentTotal. The object StudentTotal is only created when the foreignkey grade of GradeTotal and Student is same to the instant of Grade being used for the process. To do this I have the following serializer: class StudentDataSerializer(serializers.ModelSerializer): rollno = serializers.CharField() class Meta: model =StudentTotal fields = ('marks', 'rollno' ) class GradeSerializer(serializers.ModelSerializer): Fromgrade = StudentDataSerializer(many=True) class Meta: model = GradeTotal fields = ('average', 'total', 'Fromgrade', ) class MultipleGradeSerializer(serializers.ModelSerializer): GradeMarks = GradeSerializer(many=True) grade = serializers.CharField() class Meta: model = Grade fields = ("grade", "GradeMarks") def update(self, instance, validated_data): g_data = validated_data.pop('GradeMarks') for datas in g_data: a1 = datas["average"] t1 = datas["total"] g1 = GradeTotal.objects.create(grade=instance, average=a1, total=t1) data2 = datas.pop('Fromgrade') for data in data2: e1 = data["rollno"] r1 = Student.objects.get(rollno=data["rollno"]) if s1["grade"] == instance: StudentTotal.create(gradeno = g1, rollno = r1, marks =data["marks"]) return … -

Django count nested m2m objects

How to do efficient reverse foreign key check on Django multi-table inheritance model?
I've got file objects of different types, which inherit from a BaseFile, and add custom attributes, methods and maybe fields. The BaseFile also stores the File Type ID, so that the corresponding subclass model can be retrieved from any BaseFile object: class BaseFile(models.Model): name = models.CharField(max_length=80, db_index=True) size= models.PositiveIntegerField() time_created = models.DateTimeField(default=datetime.now) file_type = models.ForeignKey(ContentType, on_delete=models.PROTECT) class FileType1(BaseFile): storage_path = '/path/for/filetype1/' def custom_method(self): <some custom behaviour> class FileType2(BaseFile): storage_path = '/path/for/filetype2/' extra_field = models.CharField(max_length=12) I also have different types of events which are associated with files: class FileEvent(models.Model): file = models.ForeignKey(BaseFile, on_delete=models.PROTECT) time = models.DateTimeField(default=datetime.now) I want to be able to efficiently get all files of a particular type which have not been involved in a particular event, such as: unprocessed_files_type1 = FileType2.objects.filter(fileevent__isnull=True) However, looking at the SQL executed for this query: SELECT "app_basefile"."id", "app_basefile"."name", "app_basefile"."size", "app_basefile"."time_created", "app_basefile"."file_type_id", "app_filetype1"."basefile_ptr_id" FROM "app_filetype1" INNER JOIN "app_basefile" ON("app_filetype1"."basefile_ptr_id" = "app_basefile"."id") LEFT OUTER JOIN "app_fileevent" ON ("app_basefile"."id" = "app_fileevent"."file_id") WHERE "app_fileevent"."id" IS NULL It looks like this might not be very efficient because it joins on BaseFile.id instead of FileType1.basefile_ptr_id, so it will check ALL BaseFile ids to see whether they are present in FileEvent.file_id, when I only need to check the BaseFile ids … -
How to run django and angular into a single development server?
I have a project where I am using Angular js to consume the API that I built with Django-Framework. Currently I have to start up the django api using django development server e.g., python manage.py runserver 192.168.0.185:8080' and then I have to start up the angular (this is my webclient) js server using 'python manage.py runserver 192.168.0.185:8000 ' Is there any way I can setup my django project to to run and web client so that i will no longer be seperating the development server of api and web client . That when i run api server it will also include the web client. Any idea? . Thank you. -

How to create a required Boolean field in recent Django REST Framework?
I'm not using Django forms, so this & this are not duplicates. I've tried this workaround, but del kwargs['required'] fails with "KeyError: 'required'". This other workaround doesn't seem to do anything, possibly because the field is defined on the model as well. Ditto for this workaround. -
Interactive web application with Django/Flask issue
I want to build a website that shows some data from a CSV file and collects some user data (which should be provided through some textbox widgets) and saves it in a CSV file(the same file). I already have a working Python code for the CSV handling. The problem is that I'm not sure what programming languages I need to use besides Python in order to achieve that using Flask or Django. And I'm not familiar with web development. Can I make it using only Python and Django/Flask(or any other web framework)? If not, what languages and resources do I need? And do I need a database for that? I tried some tutorials for both frameworks but Flask seems to need HTML and CSS, and Django wasn't much clear to me. Thank you. -
How to page result and filter it by ForeignKey field in Graphql?
I am writing a graphql api in Django. I want to do the search like the example below. I am new to use graphql and I only know how to return all the object. So, I would like to know 1) how to split the result into different page which each page contain 10 result. 2) How can I filter the result by the ForeignKey field? Like, I want to filter the Expense.objects by the ExpenseDetail.date and also output it. I have tried to use expense_set to do the search but graphql report error. How can I solve the above two problems. Many Thanks. Models.py (simplified a lot): class Expense(BaseModel): id = models.AutoField() price = models.FloatField() class ExpenseDetail(BaseModel): id = models.CharField() date = models.DateField() expense = models.ForeignKey(Expense, on_delete=models.CASCADE, default=None, null=True, blank=True) Schema.py: class ExpenseType(DjangoObjectType): class Meta: model = Expense class Query(graphene.ObjectType): list_expense = graphene.List(ExpenseType, search=graphene.String()) def resolve_list_expense(self, info, search=None, **Kwargs): return Expense.objects.all() Graphql: query{ listExpense(ExpenseId:"", page:1, pageSize:10) { page pageSize totalSize expense_set{ date } } } -
Authenticating Android with firebase Authentication and send token to verify to backend Django
the issue that I will address here is a pretty common, my concern is on one part of it that I will highlight: My Android App authenticates users using firebase Authentication (either create or verify that exists), then calls various APIs on my django backend. To call APIs I need to send a token in each request so that I prevent unauthorized requests. I was planning first of using Django Authentication but since I am using firebase Auth, I'm thinking of the following approach: When a user sign-in or log-in to Android device. the Android will generate a custom token (from firebase), store it on the phone and then send it in each API to the backend. In backend, I will use firebase API to get the user from firebase (the first time) and store the token in my users model. If the token is not found in my database and not available in firebase then I return a non-authorized user. For subsequent requests I validate the token with my local users table. Please advise if this approach is the best in this case. Thank you -
form's is_valid method skipped self.full_clean method while debugging
Question: I debug the form.is_valid step. I can clearly see it called self.errors but it skipped the self.full_clean() ; What I tried: I think it is because self._errors is not None but a empty dict. but have no idea where and when self._errors was set(I followed the form instantiate step but it's too complex so nothing found) Anyone knows about this? -

Overwriting Image with same name - Django
Through my project, I have users upload a profile picture. I save the profile picture as userID.jpg. If they upload a new profile picture, I want to overwrite the old profile picture, so I don't waste storage space. By browsing previously asked questions on stackoverflow, I redefined the OverwriteStorage: class OverwriteStorage(FileSystemStorage): def get_available_name(self, name, max_length=None): if self.exists(name): os.remove(os.path.join(settings.MEDIA_ROOT, name)) return name When I upload the profile picture, I can see in the directory on my computer that the picture has been overwritten successfully.The image is saved with the path "media/profile/userID.jpg". However, when I display the image on my site, it is still the old picture. Through the Django site, when I open the path, I see the old picture, and when I try to change it through the admin, I get the following error: [WinError 32] The process cannot access the file because it is being used by another process: '\media\\profile\\userID.jpg' I guess I am incorrectly overwriting the file and another instance is still open, and to solve it, I need to properly close the image before overwriting. I tried doing that, but to to no success. -

In Django how to mock an object method called by views.py during its import?
I am writing System Tests for my Django app, where I test the complete application via http requests and mock its external dependencies' APIs. In views.py I have something like: from external_service import ExternalService externalService = ExternalService data = externalService.get_data() @crsf_exempt def endpoint(request): do_something() What I want is to mock (or stub) ExternalService to return a predefined response when its method get_data() is called. The problem is that when I run python manage.py test, views.py is loaded before my test class. So when I patch the object with a mocked one, the function get_data() was already called. This solution didn't work either. -

I want all of the posts that have the tag apple to appear when I search. A few of the ways I have tried so far are... Post.objects.filter(tags__name__in=[""]) and Post.objects.filter(tags__post__icontains=tagquery) Neither of these returned anything so any help would be appreciated. Model: class Post(models.Model): title = models.CharField(max_length=200) live = models.BooleanField(default=False) tags = TaggableManager() slug = models.SlugField(unique=True, blank=True, null=True, default='', max_length=256) Views: class SearchListView(ListView): model = Post template_name = "public/search.html" def get_queryset(self): queryset = super().get_queryset().filter(live=True) # query = self.request.GET.get("q") # if query: # queryset = queryset.filter(title__icontains=query) tagquery = self.request.GET.get("tag") if tagquery: queryset = queryset.filter(tags__post__icontains=tagquery) return queryset
