Django save files from FileField in docker container
I have a model with a FileField. My application is running in a docker container created with a dockerfile. When I save a file it is saved on my local path instead of the containers base root.

password reset with configuration SMTP
This is my SMTP configuration for my web page. #SMTP (Simple Mail Transfert Protocole) Configuration EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.gmail.com' EMAIL_PORT = 587 EMAIL_USE_TLS = True EMAIL_HOST_USER = '*****************' EMAIL_HOST_PASSWORD = '*************' I created a web page using python and Django where the user has to login before. When the user has forgotten his password, he has the possibility to reset his password. to reset his password, the user has to enter his email then the link will be sent to his email provided during his registration. *but when the user enters his email then clicks on send, instead to send the link into his email account, the link is redirect/ sent, to the "EMAIL_HOST_USER".* Problem/Error How should I configure the SMTP (Simple Mail Transfert Protocole) so that the user receives the link of the password reset into his email account provided during his registration? please help me. -
Django Rest Framework not showing form fields for PATCH/PUT request
I have a Django project that is using Django Rest Framework. For some reason, when I go to one of my endpoints (to make a PATCH/PUT request), I am not seeing any of the form fields in the browsable API. Here is the code for the resource: models.py from django.db import models class Patient(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) diagnosis = models.CharField(max_length=200) primary_doctor = models.ForeignKey('Doctor', related_name='patients', on_delete=models.CASCADE, null=True) born_on = models.DateField() created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return "{0.first_name} {0.last_name}".format(self) views.py from rest_framework.views import APIView from rest_framework.generics import RetrieveUpdateDestroyAPIView from rest_framework.response import Response from rest_framework import status from django.shortcuts import get_object_or_404 from ..models.patient import Patient from ..serializers import PatientSerializer class Patients(APIView): def get(sef, request): patients = Patient.objects.all()[:10] serializer = PatientSerializer(patients, many=True) return Response(serializer.data) serializer_class = PatientSerializer def post(self, request): patient = PatientSerializer(data=request.data) if patient.is_valid(): patient.save() return Response(patient.data, status=status.HTTP_201_CREATED) else: return Response(patient.errors, status=status.HTTP_400_BAD_REQUEST) class PatientDetail(APIView): def get(self, request, pk): patient = get_object_or_404(Patient, pk=pk) serializer = PatientSerializer(patient) return Response(serializer.data) serializer_class = PatientSerializer def patch(self, request, pk): patient = get_object_or_404(Patient, pk=pk) serializer = PatientSerializer(patient, data=request.data['patient']) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_202_ACCEPTED) else: return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) def delete(self, request, pk): patient = get_object_or_404(Patient, pk) patient.delete() return Response(status=status.HTTP_204_NO_CONTENT) serializers.py from rest_framework import … -
Django model multiple inheritance
I am using Django 3.1 to build a rudimentary events notification app. Here are my models models.py class Event(models.Model): # WHAT just happened ? (i.e. what kind of event) # these three fields store information about the event that occured content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE,related_name='%(class)s_content_type') object_id = models.PositiveIntegerField() content_object = GenericForeignKey('content_type', 'object_id') # WHO caused it ? (this could also be the system user) actor = models.ForeignKey(settings.AUTH_USER_MODEL, blank=False, null=False, on_delete=models.CASCADE,related_name='%(class)s_user') # WHEN did it happen ? created = models.DateTimeField(auto_now_add=True) class Meta: constraints = [models.UniqueConstraint(fields=['content_type', 'object_id', 'actor'],name='%(class)s_unique_name')] class Welcome(Event): pass class Goodbye(Event): pass views.py (simplified) def say_welcome(request): data = get_params_from_request(request) Welcome.objects.create(data) def say_goodbye(request): data = get_params_from_request(request) Goodbye.objects.create(data) My question is that will I be able to carry out CRUD functionality on the Welcome and Goodbye models and then also be able to query ALL events through the Event model? -
(django) Showing posts according to interests of users
I am pretty new to Django and still learning it, but I have to create something like medium.com. I want to show posts to users according to their interests. I added an interests field with a checkbox in a sign-up form. And of course, I added a category to the Post model. So, how can I show (to logged-in users only) publications that they interested in? Here is my models.py file in posts app from django.db import models from django.utils import timezone from django.urls import reverse # Create your models here. class Post(models.Model): CATEGORY = ( ('sport', 'Sport'), ('science', 'Science'), ('it', 'IT'), ('art', "Art"), ) title = models.CharField(verbose_name="Title for publication", max_length=50) category = models.CharField(verbose_name="Category", choices=CATEGORY, max_length=50) author = models.ForeignKey("accounts.User", verbose_name="Author:", on_delete=models.CASCADE) body = models.TextField(verbose_name="Body for publication") pub_date = models.DateTimeField(verbose_name="Date:", auto_now_add=True) def was_published_recently(self): return self.pub_date >= timezone.now() - datetime.timedelta(days=1) def get_absolute_url(self): return reverse("post_detail", kwargs={"pk": self.pk}) def __str__(self): return self.title And here is my vies.py file in posts app from django.views.generic import ListView, DetailView from django.views.generic.edit import CreateView, UpdateView, DeleteView from .models import Post from django.urls import reverse_lazy class PostListView(ListView): model = Post template_name = "index.html" def get_queryset(self): return Post.objects.order_by('-pub_date') class PostDetailView(DetailView): model = Post template_name = "./posts/post_detail.html" class PostCreateView(CreateView): model = …
