Cannot install Postgis on Heroku CI
I am getting the following error when deploying my app for a test in Heroku: self = <django.db.backends.utils.CursorWrapper object at 0x7f634cc50a00> sql = 'CREATE EXTENSION IF NOT EXISTS postgis', params = None ignored_wrapper_args = (False, {'connection': <django.contrib.gis.db.backends.postgis.base.DatabaseWrapper object at 0x7f635095d2b0>, 'cursor': <django.db.backends.utils.CursorWrapper object at 0x7f634cc50a00>}) def _execute(self, sql, params, *ignored_wrapper_args): self.db.validate_no_broken_transaction() with self.db.wrap_database_errors: if params is None: # params default might be backend specific. > return self.cursor.execute(sql) E django.db.utils.OperationalError: could not open extension control file "/app/.indyno/vendor/postgresql/share/extension/postgis.control": No such file or directory .heroku/python/lib/python3.9/site-packages/django/db/backends/utils.py:82: OperationalError I have the following code in my app.json file: { "buildpacks": [ { "url": "https://github.com/heroku/heroku-geo-buildpack.git" }, { "url": "heroku/python" } ], "environments": { "test": { "addons": [ "heroku-postgresql:in-dyno" ], "scripts": { "test": "pytest" } } } } From what I concluded, I see that the error happens when the SQL command 'CREATE EXTENSION IF NOT EXISTS postgis' is executed. -

How to await a channel_layer.group_send (with @database_sync_to_async) inside a Celery shared_task?
I have a AsyncWebsocketConsumer where one method uses @database_sync_to_async to save the connected user data to the database. Now I want to call this from outside (in a celery shared_task) via channel_layer.group_send. But how can I wait for all the connected users db-operations to go through before continuing the task? Later in the shared_task I want to get all the updated db-records and brodcast it to the same group. I thought a async_to_sync wrapping the channel_layer.group_send would do this. But it sends immediately before all db-operations is done. (A work around is by putting a time.sleep(8) in between but I don't like this approach because I really dont know how long exactly it would take.) -
Django Queries Count and update
I have the following two models ASPBoookings and Athlete. The Athlete model is linked to the ASPBookings model by the foreign key named athlete. I was recently shown queries/subqueries with Views and I have been trying to use them (still learning) to provide a count of all bookings assigned to each athlete within the ASPBookings table. Once I then have the information I need the "number_of_asp_sessions" within the Athlete model to be automatically updated with each of the athletes bookings count. e.g. Athlete ID 1, may have two bookings assigned. Athlete ID 2, may have one booking assigned. The number_of_asp_sessions should then show these numbers for each of the athletes. Hope this makes sense and thanks for advance for any help. Appreciate it. Below is the code: ASPBookings Model class ASPBookings(models.Model): asp_booking_ref = models.CharField(max_length=10, default=1) program_type = models.CharField(max_length=120, default='asp') booking_date = models.DateField() booking_time = models.CharField(max_length=10, choices=booking_times) duration = models.CharField(max_length=10, choices=durations, default='0.5') street = models.CharField(max_length=120) suburb = models.CharField(max_length=120) region = models.CharField(max_length=120, choices=regions, default='Metro') post_code = models.CharField(max_length=40) organisation_type = models.CharField(max_length=120,choices=organisation_types, default='Government School') audience_number = models.CharField(max_length=10) presentation_form = models.CharField(max_length=120, choices=presentation_form_options, default='Face to Face') contact_name = models.CharField(max_length=80) email = models.EmailField() phone_number = models.CharField(max_length=120) comments = models.TextField() status = models.CharField(max_length=80, choices=statuses, default='TBC') email_sent = models.BooleanField(default=False) … -

load csv into sqlite3 db (django)
I am trying to load the csv files I upload to my sqlite3 db. I am able to upload the csv into a folder but it doesn't appear on my db. The db table structure contains as many columns as the csv with the corresponding data types; but the column names in the db table structure are different as in the csv, as some of the columns names in the csv contain spaces and special characters (like accents for example). My goal is to allow the user to upload a csv file that will be loaded to the db. I was also wondering if its possible to increment the db each time a new csv is loaded (for example: I upload a file now which is loaded to the db then the second time I add, the newer details are added to the db without deleting the previous ones). Apologies if I am unclear and asking too many things at once. Here is my model, form, function (handle upload) & views .py files: models.py class UploadForm(models.Model): file = models.FileField() class Meta: db_table = "db_table" forms.py class UploadForm(forms.ModelForm): class Meta: model = UploadForm fields = "__all__" functions.py def handle_uploaded_file(f): with open('vps_app/static/upload/'+f.name, … -

Make React pages only visible to authenticated users? (Using Django DRF for backend)
I have my JWT authentication working and I can sign up and log in via my React project, and I want to redirect the authenticated users to the homepage, where the Nav Bar will say 'log out' rather than 'log in' and 'sign up'. In Django, I would just place a {% if user.is_authenticated %} in my template, but I'm not sure how to approach this from React itself. Thanks in advance! -

forms.py class UserForm(UserCreationForm): ## email = forms.EmailField() class Meta: model = User fields = ['username', 'first_name', 'last_name', 'email'] class ProfileForm(forms.ModelForm): class Meta: model = Profile fields = ['mobile', 'address', 'image'] models.py class Profile(models.Model): name = models.OneToOneField(User,on_delete=models.CASCADE) mobile = models.IntegerField(null=True) address = models.CharField(max_length=350,null=True) image = models.ImageField(upload_to='profile_pics', default='default.png',null=True) def __str__(self): return str(self.name.username)+' Profile' @receiver(post_save,sender=User) def create_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User, dispatch_uid='save_new_user_profile') def save_profile(sender, instance, created, **kwargs): user = instance if created: profile = Profile(user=user) profile.save() views.py @login_required def profile_page(request,name): user = User.objects.filter(username=name) if request.method == 'POST': user_form = UserForm(request.POST) profile_form = ProfileForm(request.POST,request.FILES) if user_form.is_valid() and profile_form.is_valid(): user = user_form.save() Profile.objects.create(user=request.user) messages.success(request,'Your profile has been updated successfully!') return redirect('homepage') else: profile_form = ProfileForm() context = { 'user':request.user, 'user_form':user_form, 'profile_form':profile_form, } return render(request,'profile.html',context) Here I have a confusion within the differences in User object and the Profile model that I defined myself. For the fields in Profile that I created is it possible to use together with the UserCreationForm so I do not need to separate two different kinds of forms? Also, could someone help me explain when and how to use the signals in order to create or update the user profile page? Should I provide an instance if … -
Show secret key of django-otp TOTPDevice
I am using django-otp for 2FA on my Django app. In the docs we are given TOTPDevice.config_url, which can be used to generate a QR code or as a link to set up 2FA with Google Auth or similar. How can I get ONLY the secret key from a TOTPDevice object? A workaround would be to get the parameter from the URL, but it sounds odd there is not built-in way to get it? I noticed a TOTPDevice.key which is in hex format, but converting into ascii or utf-8 does not give the correct secret key. -

How to pass environment variables to Azure deployment?
I'm trying to get my API to work when deploying to Azure. My problem at the moment is that for some reason my Django app doesn't find the environment variables defined in my be-configmap.yaml -file. It tries to use a .env file (which doesnt exist) when executing python manage.py runserver 0.0.0.0:8000;. Here is my backend-deployment.yaml: apiVersion: apps/v1 kind: Deployment metadata: name: backend spec: replicas: 1 selector: matchLabels: name: backend strategy: {} template: metadata: labels: name: backend spec: containers: - args: - sh - -c - ls; python manage.py makemigrations; python manage.py migrate; python manage.py runserver 0.0.0.0:8000; env: - name: POSTGRES_USER value: xxx - name: POSTGRES_PASSWORD valueFrom: configMapKeyRef: key: DATABASE_PASSWORD name: backendSecrets - name: DATABASE_PASSWORD valueFrom: configMapKeyRef: key: DATABASE_PASSWORD name: backendSecrets image: myappcrwe.azurecr.io/backend:latest imagePullPolicy: Always name: container-backend ports: - containerPort: 8000 restartPolicy: Always serviceAccountName: "" volumes: null status: {} And this is my be-configmap.yaml: apiVersion: v1 kind: ConfigMap metadata: name: backendSecrets data: DEBUG: xxx SECRET_KEY: xxx DATABASE_NAME: xxx DATABASE_USER: xxx DATABASE_PASSWORD: xxx DATABASE_PORT: xxx Could someone look at these if there are some errors why it doesn't fin the variables?
