Django ManyToManyField field: render formset in template
There are two models with a many to many relationship like this: class Client(models.Model): first_name = models.CharField( max_length=50, ) last_name = models.CharField( max_length=50, ) class Event(models.Model): event_name = models.CharField( max_length=50, ) start = models.DateTimeField() end = models.DateTimeField() clients = models.ManyToManyField( Client, db_table='ClientsAttendingEvent', blank=True, ) I want to create 2 templates with basic forms. A "create_event.html" page, and an "edit_event.html" page. Assuming really simple forms like: class EventForm(ModelForm): class Meta: model = Event fields = ['all'] class ClientForm(ModelForm): class Meta: model = Client fields = ['all'] I am struggling a lot with the view. def UpdateEvent(request, EventID): obj = get_object_or_404(Event, pk=EventID) form = SessionsForm(instance=obj) clients_formset = inlineformset_factory(parent_model=Event, model=Client, fields=('first_name', 'last_name',)) if request.method == 'POST': form = EventForm(request.POST, instance=obj) clients_forms = clients_formset(request.POST) if form.is_valid() and clients_forms.is_valid(): final_form = form.save(commit=False) final_form.save() form.save_m2m() return HttpResponseRedirect(reverse('homepage', kwargs={'EventID': EventID})) return render(request, './forms/edit_event.html') Problem: Here I tried various solutions using formset_factory and inlineformset_factory. But I usually get "X has no ForeignKey to Y" or "No fields with name ... ", and so on. Basically I don't get how to use formset factories with a m2m field instead of foreign keys or a dedicated m2m model. Using dot-Notation, "through" and other attempts didn't succeed either. Desired outcome: Having … -
Why serializer.is_valid() is always false in this scenario?
I'm try to Update this model in Django rest-api but I don't get any idea why serializer is always not valid when I try to Update; models.py class Profile(models.Model): user = models.ForeignKey(MyUser, on_delete=models.CASCADE, to_field='email') gender = models.CharField(max_length=20, null=True, blank=True) blood_group = models.CharField(max_length=20, null=True, blank=True) dept = models.ForeignKey(Department, on_delete=models.CASCADE, to_field='short_name', null=True, blank=True, default="CSE") program = models.CharField(max_length=20, null=True, blank=True) student_id = models.CharField(max_length=20, null=True, blank=True) phone = models.CharField(max_length=20, null=True, blank=True) photo = models.ImageField(upload_to='Student/Profile/Profile_Photos/', null=True, blank=True) address = models.CharField(max_length=100, null=True, blank=True) current_semester = models.CharField(max_length=20, null=True, blank=True) level = models.IntegerField(null=True, blank=True) term = models.IntegerField(null=True, blank=True) sec = models.CharField(max_length=20, null=True, blank=True) sub_sec = models.CharField(max_length=20, null=True, blank=True) complete_cr = models.FloatField(null=True, blank=True) sgpa = models.FloatField(null=True, blank=True) cgpa = models.FloatField(null=True, blank=True serializer.py class ProfileSerializer(serializers.ModelSerializer): class Meta: model = Profile fields = '__all__' views.py class ProfileUpdateView(generics.UpdateAPIView): model = Profile serializer_class = ProfileSerializer permission_classes = [IsAuthenticated] parser_classes = (MultiPartParser, FormParser) def post(self, request): token = request.headers.get("Authorization").split(" ")[-1] print(token) try: token_obj = get_object_or_404(Token,key = token) user = token_obj.user data =Profile.objects.get(user=user) serializer = ProfileSerializer(instance = data, data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data) else: return Response({"invalid"}) except: return Response({'failed': _('bad request'),},status = status.HTTP_406_NOT_ACCEPTABLE) Already 12hrs pass.

Indirect way of usine Model.objects.all() in a formset
I'm using something like this to populate inlineformsets for an update view: formset = inline_formsetfactory(Client, Groupe_esc, form=GroupEscForm, formset=BaseGroupEscInlineFormset, extra=len(Groupe.objects.all())) (Basically I need as many extra form as there are entries in that table, for some special processing I'm doing in class BaseGroupEscInlineFormset(BaseInlineFormset)). That all works fine, BUT if I pull my code & try to makemigrations in order to establish a brand new DB, that line apparently fails some django checks and throws up a "no such table (Groupe)" error and I cannot makemigrations. Commenting that line solves the issues (then I can uncomment it after making migration). But that's exactly best programming practices. So I would need a way to achieve the same result (determine the extra number of forms based on the content of Groupe table)... but without triggering that django check that fails. I'm unsure if the answer is django-ic or pythonic. E.g. perhaps I could so some python hack that allows me to specific the classname without actually importing Groupe, so I can do my_hacky_groupe_import.Objects.all(), and maybe that wouldn't trigger the error? -
chart.js Line chart doesn't display line past a certain point in the chart
For some reason, my line chart isn't correctly displaying the lines past a certain point in the dataset and I can't figure out the reason why this is the case.

Overwriting django Integer choices output in graphene
I'm working with graphene and graphene-django and I have a problem with a IntegerField with choices. graphene create an Enum and the output is "A_1" if the value is 1; "A_2" if the value is 2 and so on. Example: # model class Foo(models.Model): score = models.IntegerField(choices=((1, 1), (2, 2), (3, 3), (4, 4), (5, 5))) # query query { foo { score } } # response { "data": { "foo": { "source": "A_1" } } } How I can overwrite this output?

SMTP mail getting bounced using Heroku, Django and Outlook (goDaddy)
So I'm having some issues with sending emails using SMTP with Django, Heroku and a GoDaddy (office 365) email. My email setup is as such: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.office365.com' EMAIL_HOST_USER = HOSTUSER EMAIL_HOST_PASSWORD = LOCALPASSWORD EMAIL_PORT = 587 EMAIL_USE_TLS = True If I send a standard test e-mail LOCALLY (i.e. by running my app locally) like this: import django django.setup() from django.conf import settings from django.core.mail import send_mail send_mail( subject = 'That’s your subject', message = 'That’s your message body', from_email = settings.EMAIL_HOST_USER, recipient_list = [some_email_address,], fail_silently = False ) It works just fine. Also, I am able to send e-mails as normal through my Outlook webmail. However, when I launch this app to Heroku and try to send a test e-mail, I get a bounce-back to my webmail that looks like this: Remote Server returned '550 5.7.708 Service unavailable.

Django administration error after changing the model
good morning, I have a problem with a django app deployed as a web app on Microsoft Azure. Basically after adding an imageField to a model, when from administration I enter in the modification of one of those objects (related to that model) I get the following error: No module named 'backend' Request Method: GET Request URL: http://......myurl...../adminforsuperuser/auth/tenants/tenant/4791c751-bc04-4bb5-aa9f-82732b7c3217/change/ Django Version: 2.2.8 Exception Type: ModuleNotFoundError Exception Value: No module named 'backend' Exception Location: in _find_and_load_unlocked, line 953 Python Executable: /opt/python/3.6.12/bin/python3.6 Python Version: 3.6.12 Python Path: ['/opt/python/3.6.12/bin', '/tmp/8d942cfe6a508ea', '/tmp/8d942cfe6a508ea/antenv3.6/lib/python3.6/site-packages', '/opt/python/3.6.12/lib/python36.zip', '/opt/python/3.6.12/lib/python3.6', '/opt/python/3.6.12/lib/python3.6/lib-dynload', '/opt/python/3.6.12/lib/python3.6/site-packages'] Server time: Fri, 9 Jul 2021 12:04:19 +0000 More details about the error: image The field I add to the model: logo= models.ImageField(upload_to=path_and_rename, default='tenant_logos/default_logo.png') Practically the fact that in edit must also show me the form to change the image (and the path of the image currently saved in that object) breaks the whole page. The strange thing is that it works locally! They, local and prod, have the same apps installed: INSTALLED_APPS = [ 'django.contrib.auth', 'django.contrib.admin', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'crispy_forms', .....my app here... , ] Thank you! -
