Authenticate method in django returns None
It is the first time I do a project in Django. As a first step, I am creating methods to sign-up and sign-in users. The sign-up works well. However, after registering an user, I try to sign-in without success. My models.py file is: from django.db import models from django.contrib.auth.models import AbstractBaseUser, BaseUserManager, PermissionsMixin class UserManager(BaseUserManager): def create_user(self, username, email, password=None, **extra_fields): user = self.model(username=username, email=email, **extra_fields) # set_password will handle the password before saving it in the database # It hash the password before saving it user.set_password(password) user.save(using=self._db) return user def create_superuser(self, username, email, password=None, **extra_fields): extra_fields.setdefault('is_staff', True) extra_fields.setdefault('is_superuser', True) return self.create_user(username, email, password, **extra_fields) class User(AbstractBaseUser, PermissionsMixin): username = models.CharField(max_length=20, unique=True) email = models.EmailField(unique=True) password = models.CharField(max_length=256) fname = models.CharField(max_length=100) lname = models.CharField(max_length=100) is_active = models.BooleanField(default=False) is_staff = models.BooleanField(default=False) objects = UserManager() USERNAME_FIELD = 'username' REQUIRED_FIELDS = ['email'] def __str__(self): return self.username class Meta: managed = True db_table = "users" and the sign-in method in views.py is the following one: def signin(request): if request.method == "POST": username = request.POST.get("username") password = request.POST.get("password") # Authenticate the user user = authenticate(request, username=username, password=password) # If it is not None - user exists and right credentials if user: login(request, user) fname = … -
Implementing Autocomplete for M2M Fields in Wagtail CustomUser Model
I have added two additional fields to my CustomUser model in my Wagtail project. These two fields are many-to-many (m2m) fields, and in the form, I want these fields to be represented as an Autocomplete feature. How can I achieve this? models.py class User(AbstractUser): journal = models.ManyToManyField("journal.Journal", verbose_name=_("Journal"), blank=True) collection = models.ManyToManyField("collection.Collection", verbose_name=_("Collection"), blank=True) forms.py class CustomUserEditForm(UserEditForm): journal = forms.ModelMultipleChoiceField(queryset=Journal.objects.all(), required=False, label=_("Journal")) collection = forms.ModelMultipleChoiceField(queryset=Collection.objects.filter(is_active=True), required=True, label=_("Collection")) class CustomUserCreationForm(UserCreationForm): journal = forms.ModelMultipleChoiceField(queryset=Journal.objects.all(), required=False, label=_("Journal")) collection = forms.ModelMultipleChoiceField(queryset=Collection.objects.filter(is_active=True), required=True, label=_("Collection")) -
Python - remove commas and leave decimal points from string as number
As of title, I need to remove commas from string number and leave decimal point, but the problem is input can be with . or ,. This input will be saved for Django model's DecimalField For example: Input: 250,000,50 250,000 250000.00 25,000 Output: 250000.50 250000.00 250000.00 25000.00 What I have tried: def _normalize_amount(self, value -> str): normalized_amount = value[:-3].replace(",", "") + value[-3:] return Decimal(normalized_amount) Problem is that this function can not handle the cases where user enters , as decimal point. How to solve this case ? -
Website wont load! How do i get my website files online via Hostinger?
Im starting up a website company that compares dentists' prices and lets you book online. Ive had a freelancer develop a python coded website using Django creating the back end and the front end. Think he used ubuntu. He showed me a loom recording of the website working and then sent me the files. I just cant get the website to load/work Ive set up my domain in godaddy - www.toothpik.co.uk I have hosting on hostinger, got a VPS server at their instruction to allow python code. Ive uploaded the files to the shared web server, then i also configured the SFTP via WinSCP and i can see the files that the Dev send me from an expanded zip file. I have linked my VPS IP to keys generated in puTTY for SSH which is enabled on my hostinger using a public key into hostinger Sorted all my DNS out so it points from godaddy to hostinger (i want to do cloud flare in future, god help me on that) getting Hello World message when visiting the website URL to Hostinger.

Display unique records in a django table
I have three models: class Member(models.Model): person_id = models.CharField(max_length=100, null=True) first_name = models.CharField(max_length=100, null=True) last_name = models.CharField(max_length=100, null=True) minit = models.CharField(max_length=1, null=True) dob = models.DateField(null=True) class Project(models.Model): project_name = models.CharField(max_length=100) project_description = models.CharField(max_length=100) project_owner = models.CharField(max_length=100) dos_from = models.DateField() dos_to = models.DateField() class Review(models.Model): member = models.ForeignKey(Member, on_delete=models.CASCADE, related_name='review_rel') project = models.ForeignKey(Project, on_delete=models.CASCADE) dos= models.DateField() review_type= models.CharField(max_length=25) Some members will have no reviews at all, some will have multiple reviews even within the same project. I would like to create a table with one row per member and project for the members who are assigned a review. When I start with the Review model, I get multiple rows for the same member (if the member has more than one review within the same project) I don’t know how to dedup it. import django_tables2 as tables class Reviews_Table(tables.Table): class Meta: model = Review fields = ( "project__project_name", "member__person_id", "member__first_name", "member__last_name", "member__minit", "member__dob", ) I also tried starting with the Member Model, but I can’t figure out how to go backwards and link to the Review model. I have been stuck on this for a while. I would truly appreciate help. Thank you -
Managing ALLOWED_HOSTS in Django for Kubernetes health check

Adding several object on the same djangoform
There is this code to register devices in a database. You fill the form with some data, like MAC, and save it. I want to implement a function where you split up several MACs with ,(comma) and for each MAC a new device is added to DB(this table has an autoincrement sequence). Basically my code is: for i in listmac.split(","): form2 = form.save(commit=False) #next_id = Net.objects.order_by('-id_seq').first().id_seq+1 #form2.id_seq=next_id form2.mac = i form2.save() The problem:\ Let's say my next id is 150.\ With the code like that, if I put 3 MACs, the code tries to add 3 devices with the seq=150, therefore only the last one is saved.\ If i uncomment those two lines, it adds correctly 150, 151 and 152, but it does not save the sequence in the autoincrement field. So if I try to insert another register directly through the database for example, it tries to insert 151 and it gives me an error. -

SimpleListFilter does nothing - but neither does any other list_filter
when applying a SimpleListFilter in Django 5 admin, I get the same queryset no matter the value. After some testing I realized, the matter is not only with the SimpleListFilter, but all fields of list_filter. class Monitor(models.Model): serial = models.CharField("serial", max_length=9, primary_key=True) status = models.PositiveSmallIntegerField("status", default=0) class StatusFilter(admin.SimpleListFilter): title = "status" parameter_name = "status" def lookups(self, request, model_admin): return [(0, "off"), (1, "busy"), (2, "on")] def queryset(self, request, queryset): print("value:", self.value(), type(self.value())) if self.value() == 0: qs = queryset.filter(status=0) print("queryset count", qs.count()) return qs elif self.value() == 1: qs = queryset.filter(status=1) print("queryset count", qs.count()) return qs elif self.value() == 2: qs = queryset.filter(status=2) print("queryset count", qs.count()) return qs print("no filter") return queryset The example of the SimpleListFilter shows the correct amount tough: The numbers in this screenshots are correct (29, 0, 6) When pressing once (!) on a filter, for example "on" I get multiple prints returned, which is many more than I would expect: value: 2 <class 'str'> no filter value: 0 <class 'int'> queryset count 29 value: 1 <class 'int'> queryset count 0 value: 2 <class 'int'> queryset count 6 value: 2 <class 'str'> no filter value: 2 <class 'str'> no filter value: 2 <class 'str'> no filter … -

How to edit list_editable only to be available before 30 days pass Django_Admin

Django migrations on celery not stoping after .save()

How to implement subquery in Django ORM?
I have a Postgres sql query that looks like below SELECT Date_trunc('hour', batch_time) + Date_part('minute', batch_time) :: INT / 10 * interval '10 min', Round(Avg(min_metric) :: NUMERIC, 2), metric_notify FROM (SELECT batch_time, Min("uptime") AS min_metric, Coalesce(CASE WHEN notify LIKE '%HIGH%' THEN 'HIGH' ELSE '' END, '') AS metric_notify FROM lt_store WHERE batch_time >= '2024-01-14 09:01:26.656059' AND batch_time <= '2024-01-15 09:01:26.656055' GROUP BY 1, 3 ORDER BY 1 ASC) AS subq GROUP BY 1, 3 As you can see, there are two queries. In the inner query, I do min aggregation on the metric with a group by on time and in the outer query, I do avg aggregation on the metric with a 10 min time interval truncation. Now I plan to replicate the same in django query and this is what I do result1 = LtStore.objects.filter(batch_time__gte='2024-01-14 09:01:26.656059', batch_time__lte='2024-01-15 09:01:26.656055' ).values ('batch_time').annotate(min_metric=Round(Min('uptime')), metric_notify=Coalesce(Max( Case( When(notify__contains='HIGH', then=Value('HIGH')), default=Value(''), )), Value('') ), ).order_by("batch_time") trunc_query = "date_trunc('hour', LtStore.batch_time) + date_part('minute', LtStore.batch_time)::int / 10 * interval '10 min'" result2 = LtStore.objects.annotate( min_metric=Subquery(result1.values('min_metric')[:1]), metric_notify=Subquery(result1.values('metric_notify')[:1]) ).extra({"trunc": trunc_query}).values( 'trunc', 'metric_notify' ).annotate( avg_metric=Avg('min_metric') ).order_by("trunc") The above django query works but I get a different result as compared to the one with sql query.

Safari Takes Excessive Time to Load and Render Server-Sent Events (SSE) in Django Application
Here's a brief overview of our implementation: Backend (Django): Sends SSEs using django-eventstream. Events are sent to a URL like https://devbackend.marshallgoldsmith.ai/events/{session_id}, where {session_id} is a unique identifier. Frontend: Uses fetchEventSource to listen to the events from the above URL. We handle various event scenarios such as onmessage, onerror, and onclose. The event stream opens fine in Chrome and even displays correctly when the URL is opened directly in a Chrome browser tab. Issue with Safari: When accessing the event stream URL in Safari, it keeps loading indefinitely and does not display any events, unlike in Chrome. There are no apparent error messages in the Safari console. we checked cross-origin issues and other compatibility issues and searched. But no luck. So if anyone face this kind of issue, please let us know. that will be more helpful. Thanks -

Issue with Forbidden Error when Accessing Django Backend through AWS API Gateway
My web application faces a perplexing 403 Forbidden Error when calling the Django backend (hosted on Railway.app) through AWS API Gateway (proxy). This error curiously only manifests in live scenarios, as testing the API Gateway endpoint from the AWS console works flawlessly. I've meticulously ruled out potential culprits like authorization mechanisms, Web ACL, and API key requirements. Interestingly, swapping out Django for a different backend, the Starwars API in this case, completely eliminates the error, hinting at a potential compatibility issue between AWS and Django in my specific configuration. To further isolate the source of the problem, I undertook the following actions: Deployed the Django app on both Railway.app and an EC2 instance, eliminating any platform-specific hosting issues. Configured Django to allow all origins and request headers, preemptively addressing potential CORS restrictions. Verified that no access-limiting resource policies were associated with either the API Gateway or the Django app. These steps successfully ruled out both hosting and CORS as potential culprits, narrowing the investigation down to the intricate configuration of the API Gateway or the logic within the Django application itself. -

My application's dependencies are bigger than 1GB in size for this reason I am using slim_handler:true parameter in zappa settings as well as increasing ephemeral size of lambda using "ephemeral_storage": {"Size": 10240}, but still i am getting error django not found in my cloudWatch logs. All my configurations are attached below: My zappa_settings.py file: { "test-staging": { "ephemeral_storage": {"Size": 10240}, "aws_region": "us-west-1", "django_settings": "lu_development.settings", "profile_name": "default", "project_name": "linkedunion-bac", "runtime": "python3.10", "s3_bucket": "zappa-sultan-test-migration", "slim_handler": true } } All the packages installed in my virtual env: aioredis==1.3.1 amqp==2.6.1 anyio==4.0.0 argcomplete==3.2.1 asgiref==3.7.2 async-timeout==4.0.3 attrs==23.1.0 autobahn==23.6.2 Automat==22.10.0 autopep8==2.0.4 backoff==2.2.1 billiard==3.6.4.0 boto==2.49.0 boto3==1.24.8 botocore==1.27.8 celery==4.4.3 certifi==2023.7.22 cffi==1.15.1 cfn-flip==1.3.0 channels==3.0.5 chardet==3.0.4 click==8.1.7 constantly==15.1.0 cryptography==41.0.3 daphne==3.0.2 Deprecated==1.2.14 Django==4.0.10 django-cacheops==7.0.1 django-cors-headers==3.14.0 django-debug-toolbar==4.0.0 django-environ==0.4.5 django-mysql==3.9.0 django-ninja==0.22.2 django-redis==5.3.0 django-simple-history==2.12.0 django-storages==1.10 djangorestframework==3.14.0 djangorestframework-simplejwt==4.6.0 durationpy==0.6 exceptiongroup==1.1.3 factory-boy==3.3.0 Faker==19.3.1 funcy==1.18 gcloud==0.18.3 geographiclib==2.0 geopy==2.4.0 googleapis-common-protos==1.52.0 grpcio==1.60.0 gunicorn==20.0.4 h11==0.14.0 hiredis==2.2.3 hjson==3.1.0 httpcore==0.17.3 httplib2==0.22.0 httpx==0.24.1 hyperlink==21.0.0 idna==2.10 importlib-metadata==6.11.0 incremental==22.10.0 jmespath==0.10.0 JSON-log-formatter==0.5.2 jws==0.1.3 kappa==0.6.0 kombu==4.6.11 markdown-it-py==3.0.0 MarkupSafe==2.1.3 mdurl==0.1.2 mysql-connector==2.2.9 mysql-connector-python==8.0.21 mysqlclient==2.0.1 numpy==1.25.2 oauth2client==4.1.2 onesignal-sdk==2.0.0 opentelemetry-api==1.19.0 opentelemetry-distro==0.40b0 opentelemetry-exporter-otlp==1.19.0 opentelemetry-exporter-otlp-proto-common==1.19.0 opentelemetry-exporter-otlp-proto-grpc==1.19.0 opentelemetry-exporter-otlp-proto-http==1.19.0 opentelemetry-instrumentation==0.40b0 opentelemetry-instrumentation-celery==0.40b0 opentelemetry-instrumentation-dbapi==0.40b0 opentelemetry-instrumentation-django==0.40b0 opentelemetry-instrumentation-logging==0.40b0 opentelemetry-instrumentation-psycopg2==0.40b0 opentelemetry-instrumentation-redis==0.40b0 opentelemetry-instrumentation-requests==0.40b0 opentelemetry-instrumentation-urllib3==0.40b0 opentelemetry-instrumentation-wsgi==0.40b0 opentelemetry-proto==1.19.0 opentelemetry-sdk==1.19.0 opentelemetry-semantic-conventions==0.40b0 opentelemetry-util-http==0.40b0 pandas==2.0.3 pdf2image==1.16.3 pep8==1.7.1 Pillow==10.0.1 placebo==0.9.0 protobuf==3.20.3 pyasn1==0.5.0 pyasn1-modules==0.3.0 pycodestyle==2.11.0 pycparser==2.21 pycryptodome==3.10.1 pydantic==1.9.1 Pygments==2.17.2 PyJWT==2.8.0 pymssql==2.2.5 … -
Django Rest Framework generic views, so clunky to get the object/instance
Often I wish to use the created/updated object, for say to log it in some history, or use it in an email. E.g.1. CreateAPIView def create(self, request, *args, **kwargs): ret = super().create(request, *args, **kwargs) # Do something with the create object here, e.g. create a history log return ret E.g.2. UpdateAPIView def update(self, request, *args, **kwargs): ret = super().update(request, *args, **kwargs) # Do something with the create object here, e.g. create a history log return ret Answers that are not solutions Use ret.data to see a dict of the object data ... because I wish to access the object so so I can look up foreign keys, call methods on it etc. Create a new object using ret.data ... wasteful to create object, through it away, and recreate it again Copy and paste most of the original create/update method just so one can save a reference to the object ... this is terrible because it's the meat of the generic view, so why event use it in the first place. The best I have come up: A CreateAPIView, e.g.: def perform_create(self, serializer): self.object = serializer.save() return self.object def create(self, request, *args, **kwargs): ret = super().create(request, *args, **kwargs) # Do something … -
pytest-django could can't find modules correctly
I have a django project with a structure like below project_root/ │ ├── Tia/ │ ├── manage.py │ ├── Tia/ │ │ ├── __init__.py │ │ ├── my_settings.py │ │ └── ... │ └── repository/ │ ├── __init__.py │ ├── tests/ │ └── ... └── pytest.ini I installed pytest-django and created a pytest.ini file. the context of the file are below: [pytest] DJANGO_SETTINGS_MODULE=MKalender.settings_local_prod_connection python_files = tests.py test_*.py *_tests.py Now I'm getting this Error when running the test only. runserver command works fine: ModuleNotFoundError: No module named 'Tia.repository' Any Idea on how to solve this?
