Heroku Django Postgre
So, I was building a Django app, I created an intro field for a post formular, I did that in my models.py file: class Post(models.Model): title = models.CharField(max_length=100) intro = models.CharField(max_length=1024) content = models.TextField() pub_date = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.title def get_absolute_url(self): return reverse('donut-post-detail', kwargs={'pk': self.pk}) I renamed 'description' into 'intro' so, when I did the makemigrations command it maked me a file named: 0002_rename_description_post_intro.py I hosted it into heroku, commited changes and migrated it when this happened: ~ $ python manage.py migrate Operations to perform: Apply all migrations: admin, auth, blog, contenttypes, sessions, sites, users Running migrations: Applying blog.0002_rename_description_post_intro...Traceback (most recent call last): File "/app/.heroku/python/lib/python3.10/site-packages/django/db/backends/utils.py", line 89, in _execute return self.cursor.execute(sql, params) psycopg2.errors.UndefinedColumn: column "description" does not exist The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/app/manage.py", line 22, in <module> main() File "/app/manage.py", line 18, in main execute_from_command_line(sys.argv) File "/app/.heroku/python/lib/python3.10/site-packages/django/core/management/__init__.py", line 446, in execute_from_command_line utility.execute() File "/app/.heroku/python/lib/python3.10/site-packages/django/core/management/__init__.py", line 440, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/app/.heroku/python/lib/python3.10/site-packages/django/core/management/base.py", line 414, in run_from_argv self.execute(*args, **cmd_options) File "/app/.heroku/python/lib/python3.10/site-packages/django/core/management/base.py", line 460, in execute output = self.handle(*args, **options) File "/app/.heroku/python/lib/python3.10/site-packages/django/core/management/base.py", line 98, in wrapped res = handle_func(*args, **kwargs) File "/app/.heroku/python/lib/python3.10/site-packages/django/core/management/commands/migrate.py", line 290, … -
Custom rest_framework_simplejwt authentication class for reading HTTPonly cookies ignores permission_classes = (permissions.AllowAny,)
I have defined a custom authentication class that extends the default rest_framework_simplejwt.authentication.JWTAuthentication as follows: myaccount.authenticate.py def authenticate(self, request): header = self.get_header(request) if header is None: # If header is None, get token from cookie raw_token = request.COOKIES.get(settings.SIMPLE_JWT['AUTH_ACCESS_COOKIE']) or None else: raw_token = self.get_raw_token(header) if raw_token is None: return None validated_token = self.get_validated_token(raw_token) return self.get_user(validated_token), validated_token I then added the following to settings.py 'DEFAULT_PERMISSION_CLASSES':[ 'rest_framework.permissions.IsAuthenticated' ], 'DEFAULT_AUTHENTICATION_CLASSES':[ 'myaccount.authenticate.CustomJWTAuthentication' ] } views.py class Login(APIView): permission_classes = (permissions.AllowAny,) def post(self, request): pass When I make a call to the above view despite having permissions set to AllowAny, I get the following response. { "detail": "Given token not valid for any token type", "code": "token_not_valid", "messages": [ { "token_class": "AccessToken", "token_type": "access", "message": "Token is invalid or expired" } ] } What could I have missed?

Python list overwritten each time the previous items
The objective of my application is to create a copy of documents and insert them into the database for each annotator, for example, let's say the master user has 3 documents and two annotators, let's say the first annotator has the email testmail1@mail.com and the second one has the email testmail2@mail.com, finally, I need to insert in the database 3 documents for testmail1@mail.com and 3 other documents for testmail2@mail.com. So to do this, I created first a list containing the copy of documents, and I didn’t assign the annotator created_documents_in_iaa = [] created_documents_in_iaa += [DocumentIAATask( name=document.name, spans=document.spans, entity=document.entity, original_document=document, IAA_Task=iaa_task) for document in all_documents_in_iaa.iterator(chunk_size=1)] And after that, I added an annotator to each document, and I append each modified created_documents_in_iaa list to the tsks_list: tasks_list = [] for user in users_instance_list: try: for i in range(len(created_documents_in_iaa)): created_documents_in_iaa[i].annotator = user tasks_list.append(created_documents_in_iaa) except Exception as e: print(e) Finally, I created a copy of documents in the PostgreSQL database: for task in tasks_list: DocumentIAATask.objects.bulk_create(task) However, in the result, I found 6 documents inside the table of the first annotator, and nothing for the other one, after I debugged the code, I found that tasks_list overwritten each time the list, that's means when I … -
Best approach to implement server-side caching on a Django GraphQL API?
I have an Angular frontend that uses Apollo Graphql client to interface with a Django Graphql backend (using graphene). It all works well, but the API is very slow, especially when there are concurrent users. I am trying a few things to speed up the API server. One of the things that I am seriously considering is to use server-side caching. I'm aware that there are some caching solutions that exist for Django out of the box, but these seem to be for caching the views. Is it possible to use these methods to cache Graphql API requests? What is the most effective caching solution for caching the responses to graphql queries in Django? I'm posting some of my project's code here so that you get a sense of how my API works. This is a sample of the Query class containing the various graphql endpints that serve data when queries are received from the client. And I suspect this is where we'll need most of the optimization and caching applied:- class Query(ObjectType): # Public Queries user_by_username = graphene.Field(PublicUserType, username=graphene.String()) public_users = graphene.Field( PublicUsers, searchField=graphene.String(), membership_status_not=graphene.List(graphene.String), membership_status_is=graphene.List(graphene.String), roles=graphene.List(graphene.String), limit=graphene.Int(), offset=graphene.Int()) public_institution = graphene.Field(PublicInstitutionType, code=graphene.String()) public_institutions = graphene.Field(PublicInstitutions, searchField=graphene.String(), limit = … -

Django Github CI cannot connect to mysql 'db'
Issue When trying to setup a Github action to test a Django project automatically, we ran into an issue with the django.yml setup. Whenever we ran the .yml, we got this exception on the last step (python manage.py test): django.db.utils.OperationalError: (2005, "Unknown MySQL server host 'db' (-3)") To state, our docker environment and tests alone work fine, just when trying to do this in a Github action, we get issues. What we have tried We have tried running a docker-compose up -d before running the test, to know for sure that our DB is running. Tried adding environment variables with DB info like this: https://github.com/Cuda-Chen/django-mysql-github-actions-demo/blob/main/.github/workflows/django-ci.yml Current code name: Django CI on: push: branches: [ main ] pull_request: branches: [ main ] jobs: build: runs-on: ubuntu-latest strategy: max-parallel: 4 matrix: python-version: [3.8] steps: - uses: actions/checkout@v3 - name: Set up Python ${{ matrix.python-version }} uses: actions/setup-python@v3 with: python-version: ${{ matrix.python-version }} - name: Install Dependencies run: | python -m pip install --upgrade pip pip install -r requirements.txt - name: Run Tests run: | python manage.py test Does anyone know what is going on here, and how we can resolve this? -

I wanted to add the Skills in the custom user, realized that there has been some drawbacks, things like, I can not add this skill field properly and when adding the age in django, I dont kno, but the age field seems a bit confusing.

Following is my View Class: from apps.embla_services.filters import RentPostFilters from django_filters import rest_framework as filters from apps.embla_services.models import RentPost from apps.embla_services.serializers import RentPostBriefSerializer class SearchRentPosts(generics.ListAPIView): def get_queryset(self): city = self.request.query_params.get("city") if city: return RentPost.objects.filter(city__name=city) else: return RentPost.objects.all() serializer_class = RentPostBriefSerializer filter_backends = (filters.DjangoFilterBackend,) filterset_class = RentPostFilters Following is my Filter Class: from django_filters import rest_framework as filters from apps.embla_services.models import RentPost class RentPostFilters(filters.FilterSet): title = filters.CharFilter(lookup_expr="icontains") is_available = filters.BooleanFilter() rent_type = filters.ChoiceFilter(choices=RentPost.RentTypeChoices.choices) category__id = filters.NumberFilter() available_from = filters.DateFromToRangeFilter() price = filters.RangeFilter() class Meta: model = RentPost fields = ["title", "is_available", "rent_type", "category", "available_from", "price"] Following is my Serializer Class: from apps.embla_services.models import RentPost class RentPostBriefSerializer(serializers.ModelSerializer): uploaded_media = FileSerializer(source='media', many=True, read_only=True) category = serializers.CharField(source="category.title") is_expired = serializers.SerializerMethodField() def get_is_expired(self, obj: RentPost): if obj.available_To and obj.available_To < date.today(): return True return False class Meta: model = RentPost fields = ["id", "available_from", "title", "created_at", "latitude", "longitude", "is_available", "uploaded_media", "delivery", "price", "rent_requests", "is_available", "is_expired", "city","category"] What i want is that after all the filters are applied to queryset, i can split this queryset into sub arrays depending upon the category. For example if query set contains 30 items of 3 different categories (10 items in each category). i want the response that is sent … -
Django: How to filter model with multiple whitespaces?
I have a model with char field with values like this: "Justin Roseman" (one single whitespace betwen words) "Justin Roseman" (two whitespaces betwen words) " Justin Roseman " (a lot whitespaces betwen words) etc. etc... I want get all records searching "Justin Roseman". My database is MySQL. I have tried the icontains function, but it does not work if there is more than one whitespace between words: results = MyModel.objects.filter(name__icontains="Justin Roseman") # Only returns values whit one whitespace between words, none whit two or more whitespaces :( Any ideas? please. Maybe whit regex? Thanks :D
