Django rest framework "Var must be a User Instance" vs "Object of type 'type' is not JSON serializable"
I'm trying to serialize a model having a foreign key "User". The concerned view snippet is: data = JSONParser().parse(request) serializer = SiteSerializer(data=data) if serializer.is_valid(): userid = data['supervisor'] user = User.objects.get(id=userid).__dict__ ## tried case I user = User.objects.get(id=userid) ## tried case II serializer.save(supervisor=user) return JsonResponse(serializer.data, status=201) The serializer is as : class SiteSerializer(serializers.ModelSerializer): supervisor = serializers.RelatedField(source='User', read_only=True) class Meta: model = Site fields = ('sitename', 'start_date', 'supervisor') The model is : class Site(models.Model): sitename=models.CharField(max_length=255) start_date=models.DateTimeField supervisor=models.ForeignKey(User,on_delete=models.PROTECT) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) def __str__(self): return "{}".format(self.sitename) When I pass supervisor object it says that object of type "Type" is not serializable and when I pass supervisor as dictionary it says that the dict variable supervisor must be a User instance. How do I sort this out and proceed?? -
Django 2 Adding Custom Template / View
i ve been looking around for couple of hours yet only old posts or kind of not simple explanations , here is my problem i customized the admin templates and now i have a left panel ( side navigation ) and a right panel for content , the thing is i want to make the django admin recognize my Additional templates so that the navigation finally works where each button refers to an HTML file . i'd be happy if someone out there guides me through this Error i'm getting : Using the URLconf defined in AdminDashWithNPMandBS.urls, Django tried these URL patterns, in this order: admin/ [name='index'] admin/ login/ [name='login'] admin/ logout/ [name='logout'] admin/ password_change/ [name='password_change'] admin/ password_change/done/ [name='password_change_done'] admin/ jsi18n/ [name='jsi18n'] admin/ r/<int:content_type_id>/<path:object_id>/ [name='view_on_site'] admin/ auth/group/ admin/ auth/user/ admin/ ^(?P<app_label>auth)/$ [name='app_list'] The current path, admin/index.html, didn't match any of these. -

boto3 ec2 & django
I'M new using django and python, i try to use aws ec2 API to create, start and stop instances in aws ec2: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/ec2.html#instance I found boto3 and i think that's the solution, but i don't know how to install in django framework i try using this in a view: import boto3 #import directly ec2 = boto3.resource('ec2') I think it's works but i receive the message: botocore.exceptions.NoRegionError: You must specify a region. According to boto docs i need to set my api keys and the region: https://boto3.amazonaws.com/v1/documentation/api/latest/guide/quickstart.html, but where i put this data in django? For me this is not the best solution because I don't use INSTALLED_APPS in settings, is there a django package or a better solution to do? -

Django date fields never evaluate equal when compared
I have two instances of a model object, and I want to do something if they differ in one field, that happens to be a DateField but, when I evaluate wether they are different, they always are, even when they have the same date. This is the code that performs the comparison: for field in fields: if 'name' in field.__dict__: field_name = field.__dict__['name'] if field_name in instance.__dict__: new_value = instance.__dict__[field_name] old_value = old_instance.__dict__[field_name] if new_value != old_value: # This line always avaluates true when fields are DateField print("{} - {}".format(old_value, new_value)) if first: first = None else: detail = detail + '\n' detail = detail + field_name + ' = ' + str(old_value) + ' --> ' + str(new_value) I am printing new_value and old_value for debugging, and I find that date fields always evaluate different, even when they have the same date: I don't know if there is an specific way for comparing date values. -
Django (PostgreSQL) query filter to exclude given letters
The user sends one of the letters from the following alphabet and I want to sent appropriate response. As you can notice there is some mixture of Cyrillic and Latin. I have the following get_queryset method: def get_queryset(self): SPECIAL_CHARACTERS = [ 'Аь', 'Гl', 'Кх', 'Къ', 'Кl', 'Оь', 'Хь', 'Хl', 'Цl', 'Чl', 'Юь', 'Яь' ] queryset = WordChechenModel.objects.all().order_by('word_chechen') first_letter = self.request.query_params.get('letter', None) if first_letter is not None: if len(first_letter) == 2: queryset = queryset.filter( word_chechen__iregex=r"^w+%s" % first_letter) else: queryset = queryset.filter(Q(word_chechen__startswith=first_letter) | Q( word_chechen__startswith=first_letter.upper())).exclude( word_chechen__startswith__in=SPECIAL_CHARACTERS) return queryset In case that user sends a request for double(mixture) letter I can filter that using regex, but if a user sends request lets to say with Аь or some of the SPECIAL_CHARACTERS characters than I have problems. Currently, I tried to exclude all words that start with one of the letters defined in SPECIAL_CHARACTERS using the following query: queryset = queryset.filter(Q(word_chechen__startswith=first_letter) | Q( word_chechen__startswith=first_letter.upper())).exclude( word_chechen__startswith__in=SPECIAL_CHARACTERS) return queryset But this gives me the following error: django.core.exceptions.FieldError: Unsupported lookup 'startswith' for CharField or join on the field not permitted, perhaps you meant s tartswith or istartswith? I would be very grateful for the ideas. The speed of processing the request is important. Therefore, it would nice … -
What's the fastest way to filter a django queryset based on a custom method?
I have a model that's recursive. Let's call it Organization. I have another model that is a child of Organization called Store. When Store's are listed in the application it is in a hierarchical format so we actually get the Organization's and include the recursive hierarchy below them. In the serializer we pass in parameters to filter the Store and we return None if the store does not match the filters. However, the catch is that the Organization will be still be returned even if it has no Stores which causes the table to have a bunch of empty pages if the Store does not match the filters. To counter this, in the viewset I want to filter the organizations based on whether or not they will have a store. queryset = [x for x in queryset if x.will_have_store()] def will_have_store(self): willHaveStore = False for organization in self.organizations.all(): willHaveStore = organization.will_have_store() if (willHaveStore): return True if (hasattr(organization, 'store') and organization.store.id ): willHaveStore = True return willHaveStore This is really close to working but it's painfully slow because it does a recursive check on every row in the database for every query. Is there anyway to make this faster? -

Creating Model instance with a randomly generated, human sized, unique id
I need a Model that has a field with a Random, Human-Sized, Unique key. We intend to use this for a human to brain-net the id to another computer and recall the data. What I have: def make_code(): numbers = "".join(random.choice(string.digits) for x in range(4)) letters = "".join(random.choice(string.ascii_lowercase) for x in range(2)) return numbers + letters class PinRecord(models.Model): pin = models.CharField(max_length=16, primary_key=True) data = models.TextField(blank=False, null=False) created = models.DateTimeField(auto_now_add=True) @classmethod def create_uniq(cls, action, data): created = False while not created: pin, created = cls.objects.get_or_create(pin=make_code(), defaults={'data':data}) return pin.pin Is there a better way to do create_uniq? Right now, there is a small chance that it loops for a long time, especially if the PinRecords don't get cleaned up properly or traffic is higher then expected. An alternate version that limits attempts to a finite number leaves us with nothing to give the user except a middle finger error. The recommended solution to the Random, Unique key problem seems to be uuid, but the users will object to writing down and retyping a uuid. -
Problem with foreign key field - Cannot assign "1": must be a "EstadoPessoa" instance
I'm creating a django app which contains user registration, but i'm stuck while I try to set the foreign key which indicates the user status (not defined, wanted or missing).
