How to do multiple request POST in django?
I have a view that sends a form to another view so that the user can review his form, and then after making another request post to save at that moment... so when the user enters the review view, he enters in request.POST and the form ends up being saved at the wrong time def resumo(request, avaliado_id): print(request.method == 'POST') perfil = Perfil.objects.filter(user_id=avaliado_id) queryDict = request.POST notas = (list(queryDict.values())) criterios = (list(queryDict.keys())) valores = (list(queryDict.values())) valores = [float(x.replace(",",".")) for x in valores[2:]] pesos = (queryDict.getlist('pesos')) pesos = [float(x.replace(",",".")) for x in pesos] res_list = [valores[i] * pesos[i] for i in range(len(valores))] media = sum(res_list) lista = zip(criterios[2:], notas[2:]) print(list(lista)) query_criterio = Criterio.objects.filter(ativo = True).values_list('id', flat=True) lista_criterio_id = list(query_criterio) if request.method == 'POST': avaliado = Perfil.objects.get(pk = avaliado_id) avaliador = request.user.perfil avaliacao = Avaliacao.objects.create(avaliador = avaliador, avaliado= avaliado, media = media) avaliacao.save() print(avaliacao.id) for nota, criterio in zip(notas[2:], lista_criterio_id): nota = Notas.objects.create(avaliacao = Avaliacao.objects.get(pk = avaliacao.id), notas = nota, criterios = Criterio.objects.get( pk = criterio)) nota.save() context = { 'media' : media, 'chaves_e_valores' : zip(criterios[2:], notas[2:]), 'perfis' : perfil, } return render(request, 'admin/resumo.html', context) in the first line "request.method == 'POST'" returns True and because of that it ends up hitting … -
Django REST - Invalid data. Expected a dictionary, but got {datatype}
Using DRF I'm attempting a PUT request to update a file in my database. I'm receiving the error seen in the title, exactly Invalid data. Expected a dictionary, but got {datatype}.. The full body says this (serializer.error_messages): { "required": "This field is required.", "null": "This field may not be null.", "invalid": "Invalid data. Expected a dictionary, but got {datatype}." } I don't see any additional helpful information in the terminal, just this exactly.

Django request doesn't save the logged in user

Why is Django generating a new session_key every time I refresh and hit a route?
I don't have SESSION_EXPIRE_AT_BROWSER_CLOSE set to true, I don't have req.session.modified set to true. And it seems like my browser cookie has a session id that's not changing on refresh. BUT, when I refresh the page and it re-hits the route, poof, I get a new session_key. So what could be causing this? I would like to keep the same session key, because I'm using it for user analytics tracking. -

Dynamically Sending Email
I have email verification working in Django, it sucessfully sends an email to inbox when I click the submit button at the bottom of the signup page, but the only problem is that it does not yet have the function where it sends an email to the address of the user who just signed up, instead, it only sends the email to the email address hard coded in the views .py file . Signup page: Views.py: Settings.py Register.html I don't even know where to begin here. I think I need a get function to pull the value from the email address form field, but I have no clue how I would even get that. Anyone have any idea? -

Django 'list' object attribute 'startswith'
I've been working to deploy my Django app to AWS but suddenly can't run in local due to an attribute error: 'list' object has no attribute 'startswith' Tracebacks i'm getting when I attempt to runserver include bootstrap and various django/core listings.

How to disable a form from views.py .?
How do I achieve the below: @login_required def close_auction(request,listing_id): listing = Listing.objects.get(pk=listing_id) if request.method == "POST": listing.Auction_closed = True **Disable the Bids on the Listing And display some message such as "The auction is Closed"** return render(request, "auctions/index.html",{ "listing": Listing.objects.get(pk=listing_id), "user": User.objects.get(pk=request.user.id), "owner": listing.owner }) Below is my code in index.html: <!-- if the user is the one who created the listing: they can close the listing go to the close_auction view to close --> {% if user == owner %} <form action="{% url 'close_auction' listing.id %}" method="post"> {%csrf_token%} <button>Close this Listing</button> </form> {% endif %} Below is my models.py: class Listing(models.Model): Title = models.CharField(max_length=64) Description = models.TextField(max_length=500) Category = models.CharField(max_length=16) Starting_Bid = models.IntegerField() Image = models.ImageField() Auction_closed = models.BooleanField(default=False) #def bid(self): #return self.Starting_Bid class User(AbstractUser): watchlist = models.ManyToManyField(Listing, blank= True, related_name="watcher") listing_owner = models.ForeignKey(Listing,on_delete=models.CASCADE,related_name="owner",null=True) class Bid(models.Model): Bid_amount = models.IntegerField() listing = models.ForeignKey(Listing, on_delete=models.CASCADE, related_name="bids") bid_placed_by = models.ForeignKey(User, on_delete=models.CASCADE, related_name="bid_placer", null=True) What I am trying to achieve here: If the user is the owner of the listing then he/she should be able to 'close the listing'. Once the listing is closed, the 'Place a Bid' form should be disabled and some message should be shown instead. -
Showing items on or after the current date and time
I asked a similar question before, regarding my Django site that I am developing and I am trying to only show users appointments on or after the current date and current time. It was recommended that I try this: now = datetime.today() appointment_wanted = Appointment.objects.filter( title=title_wanted, date__gte=now) However, once I started to test it, I noticed it works correctly for all appointments except ones that are within four hours of the current time today. -

Get input from user to use in django class based view

Within each entity, the consultant has only one profile, and so the profile can therefore be uniquely associated with the applicable entity. The problem is when the consultant works with more than one entity. That is what I would like to handle with the revised code.

psycopg2.errors.UndefinedTable: relation "libman_classbooks" does not exist
I had mistakenly deleted my migration folders for all my apps in my project. I therefore had to redo makemigrations and migrate for each of those apps. When thence I try to access the specific areas with relational paths I get an error. relation "libman_classbooks" does not exist When I try to make some changes on the models, save and try to run makemigrations and migrate. this does not go on well but returns. django.db.utils.ProgrammingError: relation "libman_classbooks" does not exist. I have been forced to guess that I need to manually create the tables in the database. Using CREATETABLE. I don't know if this is the best option though. So I think my option may be possible in development thro' the pgAdmin, but what about in production? If CREATETABLE is the best option to take, how will I do it for the production database??. I already have data in my database which do not need interference. -

When I try to update a profile_picture I get a null value for the picture and this error: Method Not Allowed: /update_profile/2/ [29/Apr/2022 14:11:16] "GET /update_profile/2/ HTTP/1.1" 405 13924 This is my API endpoint: path('update_profile/<int:pk>/', views.UpdateProfileView.as_view(), name='update_profile'), This is my UpdateProfileView: class UpdateProfileView(generics.UpdateAPIView): queryset = User.objects.all() serializer_class = UpdateUserSerializer def profile(request): if request.method == 'PUT': try: user = User.objects.get(id=request.user.id) serializer_user = UpdateUserSerializer(user, many=True) if serializer_user.is_valid(): serializer_user.save() return Response(serializer_user) except User.DoesNotExist: return Response(data='no such user!', status=status.HTTP_400_BAD_REQUEST) My UpdateUserSerializer: class UpdateUserSerializer(serializers.ModelSerializer): email = serializers.EmailField(required=False) city = serializers.CharField(source='profile.city', allow_blank=True, required=False) country = serializers.CharField(source='profile.country', allow_blank=True, required=False) profile_pic = Base64ImageField(max_length=None, use_url=True, required=False) # serializers.ImageField(source='profile.profile_pic', use_url=True, required=False) class Meta: model = User #, 'city', 'country', 'bio' fields = ['username', 'email', 'password', 'first_name', 'last_name', 'city', 'country', 'profile_pic'] # fields = UserDetailsSerializer.Meta.fields + ('city', 'country') extra_kwargs = {'username': {'required': False}, 'email': {'required': False}, 'password': {'required': False}, 'first_name': {'required': False}, 'last_name': {'required': False}, 'city': {'required': False}, 'country': {'required': False}, 'profile_pic': {'required': False} } def update(self, instance, validated_data): profile_data = validated_data.pop('profile', {}) city = profile_data.get('city') country = profile_data.get('country') profile_pic = profile_data.get('profile_pic') instance = super(UpdateUserSerializer, self).update(instance, validated_data) profile = instance.profile if … -
Is there a way to filter out items from RelatedManager in a ModelViewSet?
I'm using DRF for a simple API, and I was wondering if there's a way to achieve this behavior: I've got two models similar to the following: class Table(models.Model): name = models.CharField(max_length=100) ... class Column(models.Model): original_name = models.CharField(max_length=100) name = models.CharField(max_length=100, blank=True, null=True) ... table = models.ForeignKey(Table, on_delete=models.CASCADE, related_name="columns") And their serializers as follows: class ColumnSerializer(serializers.HyperlinkedModelSerializer): table = serializers.HyperlinkedRelatedField( read_only=True, view_name="table-detail" ) class Meta: model = Column fields = ["url", "name", "table"] class TableSerializer(serializers.HyperlinkedModelSerializer): dataset = serializers.HyperlinkedRelatedField( read_only=True, view_name="dataset-detail" ) tags = serializers.SlugRelatedField( many=True, slug_field="name", queryset=Tag.objects.all() ) columns = ColumnSerializer(many=True, read_only=True) class Meta: model = Table fields = [ "url", "name", ... "columns", ] This returns me an output similar to { ... "results": [ { "url": "http://0.0.0.0:8001/api/tables/1/", "name": "some-name", "columns": [ { "url": "http://0.0.0.0:8001/api/columns/1/", "name": "id", "table": "http://0.0.0.0:8001/api/tables/1/" }, ... } which is totally fine. But what I'd really want to do is, if a Column has name=None, it's filtered out from every API ViewSet. I've managed to do it on the ColumnViewSet by doing queryset = queryset.filter(name__isnull=False), but I can't do it for the TableViewSet or others that might show a Column list. I've tried tinkering with the ColumnSerializer, but the best I could get from it was … -
Is it possible to rename the application's group name in Django?
For example, you have "Groups" and "Users" under "AUTHORIZATION AND AUTHENTICATION" (or something named like that). If you make a new app and register its model, it's gonna write out the name of the application. I want to rename that in the admin.
