Django allauth and custom 404 page
My question is partly two. Question 1 (allauth): I have set allauth for my project to accept facebook login which works well. However i will like the user to fill a form before he complete his signup. To do this i added the following to my profile app : class CustomSignupForm(SignupForm): first_name = forms.CharField(max_length=30, label='First Name') last_name = forms.CharField(max_length=30, label='Last Name') role = forms.CharField(max_length=30, label='Role( client or pilot )',) def signup(self, request, user): user.first_name = self.cleaned_data['first_name'] user.last_name = self.cleaned_data['last_name'] user.role = self.cleaned_data['role'] user.save() return user seetings.py ACCOUNT_FORMS = { 'signup': 'profile.forms.CustomSignupForm', } **allauth settings:** SITE_ID = 1 After the facebook signin, it only ask for email and user name. Question 2(404): I have launched my app on digital ocean and i have set up a custome 404, 500, and 403 error page in my pages app: def handler404(request, exception, template_name="404.html"): response = render_to_response("404.html") response.status_code = 404 return response def handler403(request, exception, template_name="403.html"): response = render_to_response("403.html") response.status_code = 403 return response def handler500(request, exception, template_name="500.html"): response = render_to_response("500.html") response.status_code = 500 return response Project urls.py handler404 = 'pages.views.handler404' handler403 = 'pages.views.handler403' handler500 = 'pages.views.handler500' The 403 page works however both the 404 and 500 fails to work. -

Compare datetime values in django models
I have an Offer model that has a datetime field and I have two records in the database >>> oldOffer.offerDate datetime.datetime(2019, 10, 29, 15, 19, 43, 755325) >>> currOffer.offerDate datetime.datetime(2019, 10, 29, 15, 20, 2, 456100) >>> Offer.objects.filter(offerDate__lt= currOffer.offerDate) <QuerySet []> >>> Offer.objects.filter(offerDate__gt= currOffer.offerDate) <QuerySet [<Offer: Offer object (5)>, <Offer: Offer object (6)>> The currOffer.offerDate is clearly greater than the oldOffer.OfferDate. Then why am I getting an empty result with the __lt clause? Also why do I get both the oldOffer (object 5) and currOffer (object 6) when I use __gt clause? What am I doing wrong? Thanks in advance -

Error collection and propagation in Django serializers
I am struggling with collecting exceptions when using multiple Django serializers. Here is the situation. With multiple serializers, I want the last serializer (such as Beta in the following example)to collect all errors/exceptions generated while invoking the others. However, if a serializer higher in the chain (such as Alpha)raises an exception, the server stops and reports it and the view class was even reached. What should I do to propagate these exceptions to Beta and eventually send them to the front though the view? class Alpha(Serializer): def validate(self, user_data): if something wrong: raise Exception(..) return user_data class Beta(Serializer): def validate(self, data): serializer_alpha = Alpha(data['user']) if serializer_alpha.is_valid(): [do something] else: raise Exception(serializer_alpha.errors) return data In a view, the attempt is to report all the errors/exceptions that took place along the validation chain, class ParticularAppView(APIView): def post(self, request, **kwargs): serializer = Beta(data=request) if serializer.is_valid(): try: [do something] Response(response, ...) except Exception as e: Reponse(serializer.errors, ...) -

It all worked well before, but all of a sudden I can't add any new model fields: If I add any new field even if the most simple one like this: def_episode = models.IntegerField(blank=True, null=True) And manage.py makemigrations, this will happen: Traceback (most recent call last): File "D:\MyProjects\Python\Django\env\venv\lib\site-packages\django\db\backends\utils.py", line 84, in _execute return self.cursor.execute(sql, params) File "D:\MyProjects\Python\Django\env\venv\lib\site-packages\django\db\backends\sqlite3\base.py", line 383, in execute return Database.Cursor.execute(self, query, params) sqlite3.OperationalError: no such column: novelrecorder_novel.def_episode The above exception was the direct cause of the following exception: Traceback (most recent call last): File "manage.py", line 21, in <module> main() File "manage.py", line 17, in main execute_from_command_line(sys.argv) File "D:\MyProjects\Python\Django\env\venv\lib\site-packages\django\core\management\__init__.py", line 381, in execute_from_command_line utility.execute() File "D:\MyProjects\Python\Django\env\venv\lib\site-packages\django\core\management\__init__.py", line 375, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "D:\MyProjects\Python\Django\env\venv\lib\site-packages\django\core\management\base.py", line 323, in run_from_argv self.execute(*args, **cmd_options) File "D:\MyProjects\Python\Django\env\venv\lib\site-packages\django\core\management\base.py", line 361, in execute self.check() File "D:\MyProjects\Python\Django\env\venv\lib\site-packages\django\core\management\base.py", line 390, in check include_deployment_checks=include_deployment_checks, File "D:\MyProjects\Python\Django\env\venv\lib\site-packages\django\core\management\base.py", line 377, in _run_checks return checks.run_checks(**kwargs) File "D:\MyProjects\Python\Django\env\venv\lib\site-packages\django\core\checks\registry.py", line 72, in run_checks new_errors = check(app_configs=app_configs) File "D:\MyProjects\Python\Django\env\venv\lib\site-packages\django\core\checks\urls.py", line 40, in check_url_namespaces_unique all_namespaces = _load_all_namespaces(resolver) File "D:\MyProjects\Python\Django\env\venv\lib\site-packages\django\core\checks\urls.py", line 57, in _load_all_namespaces url_patterns = getattr(resolver, 'url_patterns', []) File "D:\MyProjects\Python\Django\env\venv\lib\site-packages\django\utils\functional.py", line 80, in __get__ res = instance.__dict__[self.name] = self.func(instance) File "D:\MyProjects\Python\Django\env\venv\lib\site-packages\django\urls\resolvers.py", line 584, in url_patterns patterns … -
Is it possible to somehow print 'i+1' in django template?
Scenario:I want to make a page for available slots for booking ,for which I want print time slot for 1 hour that is from i To i+1 and color it according to the availability. I am newbie to django and can't figure out the way to make a calendar and that is why I am printing time values in HTML template. Is there any other way to make this page and also is printing 'i+1' possible. Views.py @login_required def slots(request): k={ 'pro':range(8,17) } return render(request, 'login/slots.html',k) slots.html {% for i in pro %} <tr> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td id="demo">{{ i }} to {{ i+1 }}</td> </tr> {% endfor %} I know this might be a silly question but I am not able to figure it out, any help is appreciated. -

I set an 'ImageField' in the model, using postman to post data. The image uploaded successfully. However, when my view returns serializers.data, the image field is null, which is supposed to be the URL of the image. Does anyone have any ideas? I appreciate it so much. This is the response { "user": 7, "category": "2018", "cover": null, "name": "Louisville" } This is my model class Journey(models.Model): def user_directory_path(self, filename): return 'media/journey_cover/{0}/{1}'.format(self.user_id, filename) user = models.ForeignKey(to=UserProfile, related_name="journeys", on_delete=models.CASCADE) category = models.CharField(null=False, max_length=50) cover = models.ImageField(upload_to=user_directory_path) created = models.DateTimeField(auto_now_add=True) name = models.CharField(null=False, max_length=50) My serializer: class JourneySerializer(serializers.ModelSerializer): user = serializers.PrimaryKeyRelatedField(queryset=UserProfile.objects.all()) cover = serializers.ImageField(use_url=True) class Meta: model = Journey fields = ['user', 'category', 'cover', 'name'] My View class JourneyList(APIView): permission_classes = [IsOwnerOrReadOnly, permissions.IsAuthenticatedOrReadOnly] parser_classes = [MultiPartParser, FormParser] def post(self, request): print(request.content_type) serializer = JourneySerializer(data=request.data) if serializer.is_valid(raise_exception=True): journey = serializer.create(serializer.validated_data) journey.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) -
Is It Possible To Have A Theme Selector For Users Possibly In The Admin CP To Choose The Style of Their Site?
I was wondering if it's possible to have a option for users to pick from a set of themes/styles they want for there site like wordpress or forums like MyBB? I plan on releasing a script for people to use but I don't want them to all have the same theme so I would like to have a option for them to select one they like that I created or have them be able to upload/create there own. Thanks for your help!
