How to send email with cpanel in django
I'm trying to send email from a django app. Normally I use sendgrid but my client insists that there is no need for an extra service with Cpanel. Below are my settings after creating an email with cpanel according to this blog. EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'mail.mydomain' EMAIL_PORT = 465 DEFAULT_FROM_EMAIL = 'email created as above' EMAIL_HOST_USER = 'email created as above' EMAIL_HOST_PASSWORD = 'the email's password' EMAIL_USE_TLS = True However, i get this error in development: gaierror at /contact-us/, [Errno -2] Name or service not known. Any suggestions are very welcome. -
Django on Google App Engine: how to connect to cloud database to run makemigrations?
I have been following this tutorial to create Django cloud app. I have been stuck on the 'Run the app on your local computer' part of the tutorial. Before running cloud_sql_proxy.exe command, I have created .env file and pasted its contents into Permissions on Google Cloud, so theoretically, after running set GOOGLE_CLOUD_PROJECT=PROJECT_ID, I could delete this .env file from repository as it would recognize it anyway. But for now, I left it. What is more, I activate env correctly in the project dir when I ran command in this location, gcloud sql instances describe INSTANCE_NAME it works OK and displays database info. Then, I have opened new Cloud SDK and ran command: cloud_sql_proxy.exe -instances="PROJECT_ID:REGION:INSTANCE_NAME"=tcp:5434. The result is: 2021/11/08 17:11:11 Listening on 127.0.0.1:5434 for PROJECT_ID:REGION:INSTANCE_NAME 2021/11/08 17:11:11 Ready for new connections 2021/11/08 17:11:11 Generated RSA key in 116.9931ms The reason behind why it is 5434 and not 5432 and 5433 as that these ports were busy. I must say that I have also downloaded postgresql and specified these: information. After running in env (Google SDK) respectively: set GOOGLE_CLOUD_PROJECT=PROJECT_ID set USE_CLOUD_SQL_AUTH_PROXY=true python manage.py makemigrations , this error occurs: C:\Users\User\Desktop\cloud\python-docs-samples\appengine\standard_python3\django\env\lib\site-packages\django\core\management\commands\makemigrations.py:105: RuntimeWarning: Got an error checking a consistent migration history performed for database connection … -
Django query, annotate a chain of related models
I have following schema with PostgreSQL. class Video(models.Model): title = models.CharField(max_length=255) created_at = models.DateTimeField() disabled = models.BooleanField(default=False) view_count = DecimalField(max_digits=10, decimal_places=0) class TopVideo(models.Model): videos = (Video, on_delete=models.CASCADE, primary_key=True) class Comment(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) video = models.ForeignKey(Video, related_name="comments", on_delete=models.CASCADE) The reason I have a TopVideo model is because I have millions of videos and querying them takes a long time on a cheap server, so I have a secondary model that is populated by a celery task, and flushes and re-populates on each run, which makes the homepage load time much faster. The task runs the query that you see next, and saves them into the TopVideo model. This way, the task may take long to run, but user doesn't have to wait for the expensive query anymore. Before having the TopVideo model, I ran this query for my homepage: videos = ( Video.objects.filter(created_at__range=[start, end]) .annotate(comment_count=Count("comments")) .exclude(disabled=True) .order_by("-view_count")[:100] ) This worked perfectly and I had access to "comment_count" in my template, where I could easily show the number of comments each video had. But now that I make this query: top_videos = ( TopVideo.objects.all().annotate(comment_count=Count("video__comments")) .select_related("video") .order_by("-video__view_count")[:100] ) and with a simple for-loop, videos = [] for video in top_videos: videos.append(video.video) … -
How to force a value when creating with django-rest-framework ModelViewSet?
I have an api where users can create different objects. If the user is part of the staff, he can create the object with all the values he wants. However, if the user is not part of the staff, I want to force the value of a particular field. I added the following code to a viewset that works well: @swagger_auto_schema(responses={201: CategoryProductSerializer}) def create(self, request, *args, **kwargs): if not self.request.user.is_staff: request.data['client']=request.user.profil.client.pk print(request.data) serializer = self.get_serializer(data=request.data) serializer.is_valid(raise_exception=True) self.perform_create(serializer) headers = self.get_success_headers(serializer.data) return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers) def perform_create(self, serializer): serializer.save() How can I "generalize" this to all my modelviewsets? The important part of this create that must be common to all my viewsets is : if not self.request.user.is_staff: request.data['client']=request.user.profil.client.pk -
custom form error messages for too many images
I have a form that allows a user to upload bulk images. I Set a limit so the users can only upload a certain number of images. The code works but I use an exception, I want a custom error message in the template. From my research it seems that I need to use the clean method. However I cannot figure out how to use in in a function based view. How would I go about solving this issue. def createPostView(request): currentUser = request.user postForm = PostForm() if request.method == 'POST': postForm = PostForm(request.POST, request.FILES) if len(request.FILES.getlist('images')) > 3: raise Exception("Only three images allowed") else: if postForm.is_valid(): PostFormID = postForm.save(commit=False) PostFormID.author = request.user PostFormID.save() for f in request.FILES.getlist('images'): test = PostImagesForm(request.POST, request.FILES) if test.is_valid(): instance = test.save(commit=False) instance.post_id = PostFormID.id instance.images = f instance.save() return redirect('post-detail', PostFormID.pk) return render(request, 'blog/post_form.html', {'postForm': postForm, 'PostImagesForm':PostImagesForm}) -

Django Graphene (GraphQL) Filter on ManyToMany
I am working on an application using Django. We've exposed the models using Graphene. We have the following models: class Agent(models.Model): id = models.UUIDField(default=uuid.uuid4, unique=True, primary_key=True, editable=False) name = models.CharField( max_length=MAX_LENGTH, null=True, blank=True, help_text="Name of the agent" ) teams = models.ManyToManyField( 'Team', blank=True, help_text="The teams of which the user is part" ) class Team(models.Model): id = models.UUIDField(default=uuid.uuid4, unique=True, primary_key=True, editable=False) name = models.CharField( max_length=MAX_LENGTH, help_text="Name of the team" ) Now I am trying to perform a filter on a ManyToMany field. But I can't seem to get it to work. I am trying to reproduce the following Django Query in GrapQL: teams = [ Team.objects.get(id="6d6d1d4d-c1b4-485a-9269-f7e9d06d862a"), Team.objects.get(id="7e082abf-584b-4858-b510-4c71fc295e2f"), ] agents = Agent.objects.filter(teams__in=teams).distinct() I tried to achieve this by enabling the 'in' filter on the node. class AgentNode(DjangoObjectType): class Meta: model = Agent filter_fields = { "teams": ["in"] } Then I tried to execute the following query, but that didn't work as expected: query getAllAgents{ allAgents(teams_In:["6d6d1d4d-c1b4-485a-9269-f7e9d06d862a, 7e082abf-584b-4858-b510-4c71fc295e2f"]) { id name teams { id name } } } This gives me the following error: { "errors": [ { "path": [ "allAgents" ], "message": "'list' object has no attribute 'split'", "locations": [ { "column": 3, "line": 2 } ] } ], "data": { "allAgents": null … -

Django Deployment on Heroku Issue
Folks I've been steadily working through error codes trying to deploy a Django app on Heroku since yesterday. Design/front end is more my skillset, and I'm struggling to get my head around it.

How can I handle multiple requests at the same time in Django?
I'm currently writing an API in which a user could transfer money from their account to a phone but I'm facing an issue which is the user can call the API more than once at the same time and ask for transferring the money. Normally the balance of his account wouldn't be correct after the calls so I searched a lot and found out that I can use atomic transactions and lock the database. Now if the user uses the API for example twice, one of them runs correctly but the other one gets django.db.utils.OperationalError: database is locked error. Any idea how can I handle both of them correctly? (I could use a while and wait until the database gets unlocked but I rather don't do that) models.py @transaction.atomic() def withdraw(self, amount, phone, username): property = transferLog.objects.filter(username=username).order_by('-time').select_for_update()[0] if property.property >= int(amount): self.username = username self.property = property.property - int(amount) self._from = username self._to = phone self.amount = int(amount) self.time = str(datetime.datetime.now()) self.save() return {'result': 'success', 'message': 'transfer complete', 'remaining': self.property} else: return {'result': 'error', 'message': 'not enough money'} -
