Can I change the default forms name template that Django uses?
I know that Django uses default names for it's template engine, for example if I have a Form for Comments Model, Django it's going to search for comments_form.html for render that form. But can I change that? Instead of using comments_form for the form render can I use another html as template? How can I do this using Class Based Views? -

Django REST: Files\Images Uploading

Django migrate: no migrations to apply
I just added a simple model to my Django app in models.py, I added a view, a form and a template for it as well but I don't believe this matters: class SoldKit(models.Model): number = models.CharField(max_length=100) quotation = models.CharField(max_length=100) Running ./manage.py makemigrations used to be enough but apparently since I don't know when I have to add the app name, so I run: ./manage.py makemigrations files This shows various changes, of which I am sure only the SoldKit is a true change, but OK. Output: Migrations for 'files': files/migrations/0001_initial.py - Create model Contact - Create model Document - Create model Kit - Create model Profile - Create model Project - Create model PubkeyFile - Create model Setting - Create model SoldKit Then, I was tought to run migrate, to actually perform the changes, so I type: ./manage.py migrate Result: Operations to perform: Apply all migrations: admin, auth, contenttypes, files, sessions Running migrations: No migrations to apply. Which clearly is false because I did add a model... Also, I still receive an error on the page where the model is used, namely: (1146, "Table 'databaseA.files_soldkit' doesn't exist") The only way I know is to remove and recreate the database but this … -
Django multiplechoicefield not rending on page
I'm trying to get a form that takes in a name and month and will return students with that name and month (attendance system).

How to check if instance of model exists in django template
I have a django app with a basic model (Job). Now in my template I would like to check if an instance exists of that model or not. I want to project a text if there is nothing yet to show, otherwise I'd like to show the model attributes. Somehow like so (which obviously doesn't work): {% if job.title != "" %} {{ job.title }} {% else %} hola {% endif %} Also tried: {% for job in jobs %} {% if job.title %} {{ job.title }} {% else %} Hola {% endif %} {% endfor %} It makes sense it doesn't work because how can I loop through it or return something if it doesn't exist. Is there a simple way to even do that in a template? Or do I have to write my own function? Or what would be a way to do that? Help is of course very much appreciated -
Where do I have to put test_*.py files in Django?

I don't know how to show my files like most do, but here is an image! This app is also added in settings.py Thanks -
How do I get my Django query to only return an average and another column?
I'm using Django and Python 3.7. I have these models ... class Article(models.Model): website = models.ForeignKey(Website, on_delete=models.CASCADE, related_name='articlesite') title = models.TextField(default='', null=False) path = models.TextField(default='', null=False) url = models.TextField(default='', null=False) created_on = models.DateTimeField(db_index=True, default=datetime.now) class ArticleStat(models.Model): objects = ArticleStatManager() article = models.ForeignKey(Article, on_delete=models.CASCADE, related_name='articlestats') elapsed_time_in_seconds = models.IntegerField(default=0, null=False) hits = models.FloatField(default=0, null=False) I want to write a Django query that returns two columns of data -- an elapsed_time_in_seconds (from the ArticleStat model above) and an average of the hits for this particular interval. There are a couple of other constraints in the mix. I have no idea how to do this. I tried the below qset = ArticleStat.objects.annotate(avg_score=Avg(F("hits")), hour=(Func( Func( F("article__created_on"), function='HOUR FROM'), function='EXTRACT'))).filter( article__website=website, hour=hour) but this results in the error, "TypeError: expected string or bytes-like object". I'm confused about how to specify the "GROUP BY" part of my SQL statement, and then I'm confused about how to return the two columns of data I want, since I think the above only returns ArticleStat objects, which wouldn't include my average in there. -
Should I always trust W0613 pylint warnings in Django, especially for functions which have **kwargs as parameters?
Using Pylint on Django code, I frequently get the W0613 warning. 90% of the time the cases are relevant, when the variable is declared and not used. But sometimes I think it's not. W0613: Unused argument 'kwargs' (unused-argument) Example that triggers the warning, a view that handles the 500 error: def error_500(request, *args, **kwargs): ''' A 500 error handling view ''' data = {} return render(request, '500.html', data) In the above case if we remove **kwargs, starting by Django 2.2 (as I remember), any 500 error situation leads to an unhandled exception which turns into a crash. So I am confused if Pylint really understands all the situations that can appear or not. Should I always treat the warning as a real warning because my code lacks something, or should I know these exceptional case? I noticed that by using the special Pylint for Django this type of warning usually doesn’t appear as often (pylint-django). But this is a case where the W0613 gets triggered even with the Pylint-django plugin loaded in Pylint: @csrf_exempt def ipn(sender, **kwargs): ''' Paypal IPN listener. It gets triggered after every each payment. ''' msg = sender.POST.get('payer_email') print(msg) sys.stdin = sender return HttpResponse(msg) -
DRF Return 201 if user has not voted and 400 if voted
I need to make simple API where I am sending a form that creates a vote instance and return 201 status code, but if user have already voted it returns 400 bad request. my models looks like: class Company(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) short_name = models.CharField(max_length=24) def __str__(self): return f"{self.short_name}" class Vote(models.Model): voter = models.ForeignKey(Company, on_delete=models.CASCADE) date_voted = models.DateField(auto_now=True) def __str__(self): return f"{self.id}/{self.voter}" views.py: class VoteView(CreateAPIView): queryset = Vote.objects.all() serializer_class = TaskCreateSerializer permission_classes = (IsAuthenticated,) def perform_create(self, serializer): pass and serializers class TaskCreateSerializer(ModelSerializer): class Meta: model = Vote fields = [ ] For now it just always returns 201. I am looking for a way where I can write logic that can check if Vote instance for current user exists then return Response(data={"message":"You have already voted"}, status=status.HTTP_400_BAD_REQUEST). The simplest way. -

Returned a template response with no `template_name` attribute set on either the view or response It seems that I need to define template_name= on return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) on post method, but I can't find how. -
Django: How to add multiple class-based forms in a single view?
In my models.py I have a parent class with one child and one grandchild class. The parent has a one-to-many relationship with the child and the child has a one-to-many relationship with the grandchild. I would like to create a view (preferably a class-based view as these seem easiest to implement) which includes 3 class-based forms, one for the parent, multiple for the child and multiple for grandchild. What I would like to get is a view in which I can submit a form that will create one parent with multiple children with multiple grandchildren. How would I go best about designing such a view? models.py: class Parent(models.Model): parent_propery_one = models.CharField(max_length=200) parent_propery_two = models.CharField(max_length=100) parent_propery_three = models.TextField() parent_property_four = models.URLField(max_length=300, null=True) parent_property_five = models.DateTimeField(default=timezone.now) parent_property_six = models.DateTimeField(auto_now=True) parent_property_seven = models.ForeignKey(User, on_delete=models.PROTECT) ... class Child(models.Model): child_propery_one = models.CharField(max_length=200, unique=True) child_property_two = models.ForeignKey(Vilt, default=1, verbose_name="Bierviltje", on_delete=models.PROTECT) child_property_three = models.BooleanField() ... class Grandchild(models.Model): grandchild_property_one = models.CharField(max_length=200) grandchild_property_two = models.ForeignKey(Pand, default=1, verbose_name="Pand", on_delete=models.PROTECT) grandchild_property_three = models.DecimalField(max_digits=4, decimal_places=2) grandchild_property_four = models.PositiveIntegerField() grandchild_property_five = models.DecimalField(max_digits=8, decimal_places=2) grandchild_property_six = models.DecimalField(max_digits=8, decimal_places=2, default=0) grandchild_property_seven = models.DecimalField(max_digits=8, decimal_places=2, default=0) grandchild_property_eight = models.DecimalField(max_digits=8, decimal_places=2) views.py class ParentCreateView(LoginRequiredMixin, CreateView): model = Parent template_name = 'parent/parent_form.html' fields = ['parent_property_one', 'parent_property_two', 'parent_property_three', 'parent_property_four', … -

Django: how to fetch records only that matches the region belongs to login user?
Data: Transaction table with region field (Oracle database-Only read access). Users tables in excel with region field. (I can add this to data in another database) LDAP Authentication is used.

Why can I not show my current_url with my detail_view?
I am a bit confused. I have a django app and I am trying to print out my current urls. Or better my current path of my website. I have two views which I gave the names: list_view (for listing all instances) detail_view (for showing details of my instances) On my main page I'd like to get the current path. I do that like that: {% url 'detail_jobs' as detail %} {% url 'list_jobs' as list %} {{ detail }} {{ list }} My urls are: urlpatterns = [ path('jobs', list_jobs, name="list_jobs"), path('jobs/<int:id>/', detail_view, name="detail_jobs"), ] Now the {{list}} variable gives me back my current path, whereas the detail_view is giving me back nothing. Why? I don't get that.... I also have this function, which shouldn't interfere: def get_absolute_url(self): return reverse("detail_jobs", kwargs={"id" : self.id}) Any help is appreciated, thanks!! -

Check my frontside. my serializers.py: from django.shortcuts import render from rest_framework import viewsets, generics, permissions, filters, decorators from django.contrib.gis.db import models from django.contrib.gis.geos import * from django.contrib.gis.db.models.proxy import SpatialProxy from .models import * from .serializers import * class FcaUseSet(viewsets.ModelViewSet): queryset = FcaUse.objects.all() serializer_class = FcaUseSerializer permission_classes = (permissions.AllowAny,) and my models.py: from classification_list.models import* from django.contrib.gis.db import models from django.contrib.gis.geos import * from django.contrib.gis.db.models.proxy import SpatialProxy class FcaUse(models.Model): id_fca = models.ForeignKey(Fca, blank=True, null=True, on_delete=models.DO_NOTHING) fell_form = models.ForeignKey(ShapeFelling, blank=True, null=True, on_delete=models.DO_NOTHING, verbose_name='kind1') fell_type = models.ForeignKey(TypeFelling, blank=True, null=True, on_delete=models.DO_NOTHING, verbose_name='kind2') main_type = models.ForeignKey(TypesForestry, blank=True, null=True, on_delete=models.DO_NOTHING, verbose_name='kind3') sortiment = models.ForeignKey(ForestSort, blank=True, null=True, on_delete=models.DO_NOTHING, verbose_name='compos') ed_izm = models.ForeignKey(UnitMeas, blank=True, null=True, on_delete=models.DO_NOTHING, verbose_name='values') vol_drew = models.FloatField(blank=True, null=True) fca_res = models.SmallIntegerField(blank=True, null=True) vol_res = models.FloatField(blank=True, null=True) kind_id_id = models.ForeignKey(ForestKind, blank=True, on_delete=models.DO_NOTHING, verbose_name='group'), class Meta: verbose_name = 'using' verbose_name_plural = 'usings' managed = True
