Programmatically generate Django models for legacy databases
I'm trying to find out if there is a way to programmatically generate Django models for legacy databases. So given a list of legacy tables, create a model for each one. Here is an example of what I mean class Person_001(models.Model): id = models.IntegerField(primary_key=True) huge_dataset = models.CharField(max_length=70) class Meta: managed = False db_table = 'person_001' So for example, create this model for person_001, person_002 etc... I realize there may be a more efficient way of storing this data and I am opened to suggestions, but the data has been stored this way because huge_dataset is, well, huge. -

hey guys I'm trying to implement a feature in the user system where if you click the "is_staff" option another options pops up saying to enter your staff_id number.

Django: update a model with the current user when an non-model form field is changed
I'm building a page that allows users to edit Task and related Activity records (one task can have many activities), all on the same page. I want to allow the user to "adopt" one or more activities by ticking a box, and have their user record linked to each activity via a ForeignKey. Here are extracts from my code... models.py from django.contrib.auth.models import User class Task(models.Model): category = models.CharField(max_length=300) description = models.CharField(max_length=300) class Activity(models.Model): task = models.ForeignKey(Task, on_delete=models.CASCADE) title = models.CharField(max_length=150) notes = models.TextField(blank=True) owner = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, blank=True) The activity "owner" is linked to a User from the Django standard user model. I added an extra field in the form definition for the adopt field - I don't want to add it to the model as I don't need to save it once it's done it's job. forms.py class ActivityForm(forms.ModelForm): adopt = forms.BooleanField(required=False) class Meta: model = Activity fields = '__all__' views.py def manage_task(request, pk): task = Task.objects.get(pk = pk) TaskInlineFormSet = inlineformset_factory(Task, Activity, form = ActivityForm) if request.method == "POST": form = TaskForm(request.POST, instance = task) formset = TaskInlineFormSet(request.POST, instance = task) if form.has_changed() and form.is_valid(): form.save() if formset.has_changed() and formset.is_valid(): ## ?

Django rest framework Detail not found while deleting
i have a a problem deleting an object via API. So i have 2 models, Answer and Vote vote is connected to Answer via foreignKey like this class Vote(models.Model): class AnswerScore(models.IntegerChoices): add = 1 subtract = -1 score = models.IntegerField(choices=AnswerScore.choices) answer = models.ForeignKey('Answer', on_delete=models.PROTECT) user = models.ForeignKey('users.CustomUser', on_delete=models.PROTECT) class Meta: unique_together = ('answer', 'user',) Now i have an API endpoint for creating a Vote for user on a particular answer path('answers/<int:pk>/vote', VoteCreate.as_view()), Looks like this: class VoteSerializer(serializers.ModelSerializer): user = serializers.PrimaryKeyRelatedField(read_only=True, default=serializers.CurrentUserDefault()) answer = serializers.PrimaryKeyRelatedField(read_only=True) class Meta: model = Vote fields = '__all__' class VoteCreate(ParentKeyAPIView, generics.CreateAPIView): model = Vote parent_model_field = 'answer_id' serializer_class = VoteSerializer def perform_create_kwargs(self, **kwargs): return super().perform_create_kwargs(user=self.request.user, answer_id=self.kwargs['pk'], **kwargs) And i also want to delete the same vote using url like this path('answers/<int:pk>/voteDelete', VoteDelete.as_view()), Because i know that only 1 user(request.user) can have 1 Vote per answer. So i tried doing it similarly to creating class VoteDelete(generics.DestroyAPIView): serializer_class = VoteDeleteSerializer def get_queryset(self): queryset = Vote.objects.get(user=self.request.user, answer_id=self.kwargs['pk']) return queryset Im using the same serializer just like above* I get an error: Not Found: /api/v1/answers/55/voteDelete There is no any traceback, i have checked in fact that in database the Vote with answer_id 55 exists and i can delete them via … -

SMTPAuthenticationError in Weblate (which uses Django)

Options for running on user demand asynchronous / background tasks in Django?
My Django app generates a complex report that can take upto 5 minutes to create. Therefore it runs once a night using a scheduled management command. That's been ok, except I now want the user to be able to select the date range for the report, which means the report needs to be created while the user waits. What are my options for running the tast in the background? So far I've found these: Celery - might work but is complex django-background-tasks looks like the right tool for the job but hasn't been updated for years, last supported Django is 2.2 The report/background task could be generated by AWS Lambda, basically in a microservice, which Django can call, Lambda can execute the background task then call the Django app with output once finished. This is what I did last time but not sure it would work now as I'd need to send the microservice 10mb of data to process. Use subprocess.popen which someone here said worked for them but other reports say it doesn't work from Django. -

Field 'id' expected a number but got <User: ben>
I created a population script for a django website however, after running the script and making migrations, I logged in to the django admin page for my site to access the objects created using the script and could not do it for my Business model. It works fine for my other models. I get this error when I try to access the registered Businesses in my database from the Django admin page. It does not seem to trace back to any of my code but rather to a template in the admin folder of my python environment. Here's the error message: error message Here are my models: class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) profile_pic = models.ImageField(upload_to="profile_images", blank=True, default="profile_images/default.png") description = models.TextField(max_length=1024, default="") # boolean flag for identifying business owners is_business_owner = models.BooleanField(default=False) def __str__(self): return self.user.username class Business(models.Model): owner_fk = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=128) address = models.CharField(max_length=128) img = models.ImageField(upload_to="business_images", blank=True) slug = models.SlugField(unique=True) class Meta: verbose_name_plural = 'Businesses' def save(self, *args, **kwargs): self.slug = slugify(self.name) super(Business, self).save(*args, **kwargs) def __str__(self): return f"{self.name} owned by {UserProfile.objects.get(pk=self.owner_fk).username}" Here is how I created the objects through the population script: def add_user(username, firstname, lastname, password, profile_pic, description, is_business_owner): new_user = User.objects.get_or_create(username=username, password=password, … -

sorting search result in django rest framework
I have written a search api for my website in django rest framework. when you search a name (e.g. "jumanji") there might be more than one result for the search for many reasons. what I want is for the result to be ordered by the "rating" field or "releaseDate" field of the Film model. here are my codes. # models.py class Film(models.Model): filmID = models.AutoField(primary_key=True) title = models.CharField(max_length=150) duration = models.PositiveIntegerField() typeOf = models.IntegerField(validators=[MaxValueValidator(3), MinValueValidator(1),]) rating = models.FloatField(default=0, validators=[MaxValueValidator(10), MinValueValidator(0),]) releaseDate = models.DateTimeField(null=True) # serializers.py class FilmSerializer(serializers.ModelSerializer): class Meta: model = Film fields = [ "filmID", "title", "price", "duration", "typeOf", "numberOfFilminoRatings", "filminoRating", "rating", "releaseDate", "detailsEn", "salePercentage", "saleExpiration", "posterURL", "posterDirectory", ] # views.py '''Override get_search_fields method of SearchFilter''' class DynamicSearch(filters.SearchFilter,): def get_search_fields(self,view, request): return request.GET.getlist('search_fields',[]) '''Override page_size_query_param attribute of PageNumberPagination''' class CustomizePagination(PageNumberPagination): page_size_query_param = 'limit' """Pagination Handler""" class PaginationHanlerMixin(object): @property def paginator(self): if not hasattr(self, '_paginator'): if self.pagination_class is None: self._paginator =None else : self._paginator = self.pagination_class() else : pass return self._paginator def paginate_queryset(self,queryset): if self.paginator is None: return None return self.paginator.paginate_queryset(queryset, self.request, view=self) def get_paginated_response(self,data): if self.paginator is None: raise "Paginator is None" return self.paginator.get_paginated_response(data) class SearchFilm(APIView,PaginationHanlerMixin): authentication_classes = () permission_classes = (AllowAny,) def __init__(self,): APIView.__init__(self) self.search_class=DynamicSearch self.pagination_class=CustomizePagination def filter_queryset(self,queryset): … -
How to reuse an existing python Enum in Django for chocies?
Django has its own Enumeration types like model.TextChoices. However, if you already use traditional python Enum objects in your codebase, it would be nice to reuse them for fields definition without redefining all the values. Is there an elegant straightforward way to do this without too much boilerplate? What I tried: building a models.TextChoices class from the Enum seems impossible without manually declaring the values building the choices parameter from the Enum instead of dealing with models.TextChoices but then things like obj.field == ENUM.XXX won't work because Enums don't do value comparisons like models.TextChoices does among other things. Any elegant way to do this? form enum import Enum class YEAR_IN_SCHOOL(Enum): FRESHMAN = 'FR' SOPHOMORE = 'SO' JUNIOR = 'JR' SENIOR = 'SR' GRADUATE = 'GR' class MyModel(models.Model): year_in_school = django_model_field_choices_using_enum(YEAR_IN_SCHOOL) So that: Comparaison with the ENUM works my_model.year_in_school == YEAR_IN_SCHOOL.FRESHMAN Saving using the Enum works my_model.year_in_school = YEAR_IN_SCHOOL.FRESHMAN my_model.save()
