Zappa async task not being async
I'm adding a function to send emails from my zappa serverless application The sending mail process can run over the 30 seconds limit of AWS Api Gateway, giving the user a 504 response. So, following the approach on Zappa documentation, I have tried to set an asynchronous execution The code seems to be very simple from zappa.asynchronous import task from django.core.mail import send_mail as django_send_mail @task def send_mail(subject, body, from_email, to_emails): django_send_mail( subject, body, from_email, to_emails, fail_silently=False, ) Then in my function I just call the async function: send_mail( 'My Subject', 'My email body', 'noreply@mydomain.com', [user.email], ) Still, get a 504 I have tried setting it as sns, added to zappa_settings.json then "async_source": "sns", And then on the code: from zappa.asynchronous import task_sns @task_sns def send_mail(subject, body, from_email, to_emails): django_send_mail( subject, body, from_email, to_emails, fail_silently=False, ) Same error Last, I have tried invoking it directly with from django.core.mail import send_mail as django_send_mail enter code herefrom zappa.asynchronous import run def send_mail(subject, body, from_email, to_emails): run( django_send_mail, (subject, body, from_email, to_emails), {'fail_silently': False}, service='sns', ) I also tried removing the service parameter It seems that for some reason, Zappa doesn't understand that this is a lambda environment and run it synchronous? -

Python django Foreign Key Relationships problem
I am working on an online school project, where I got classes, and in the classes I have different subjects, I added a one-to-many(ForeignKey) Relation between "Classes" and "Subjects", but when it comes the view theme on the HTML page Subjects from 2.Class comes to show on 1.Class one page(all Subjects are showed in one class) How to Fix this problem?? (How to keep 2.Class Subjects in the 2.Class page as well for 1.Class?) MY CODE viws.py def classes(request): classes = Class.objects context={ 'class':classes } return render(request, "templates/Classes.html", context) def subjects(request, sub_id): classes=get_object_or_404(Class, pk=sub_id) subject=Subject.objects.all() context={ 'classes':classes, 'subject':subject } return render(request, "templates/Subjects.html", context) Models.py class Class(models.Model): title=models.CharField(max_length=200) image=models.ImageField(upload_to="images") class Subject(models.Model): title=models.CharField(max_length=2000) Class=models.ForeignKey(Class, on_delete=models.CASCADE) Webpage {%for subject in subject.all%} <div class="cardrow"> <div class="cardcolumn"> <a href="#"> <div class="card"> <h1>{{subject.title}}</h1> </div> </a> </div> </div> {%endfor%} So again all subjects are showing in one class. tho I added a Foreign Key relationship Thanks -
Work with a Django model (table) with an external python script
I am working with django and I have created some models (tables). Working directly on my django project all is ok, I can visualize and modify data with no problems. But when I want to work directly with a Python script out of my Django project, it can't access to the tables, because it says the table doesn't exist. Below I show from the PostgreSQL dashboard one of my tables. How I have to do it, to work with it, in a independent python script? I have done something like this, import psycopg2 # Trabajar con PostgreSQL def bbdd_connect(): con = psycopg2.connect( host = '127.0.0.1', database = 'lorawan_platform_app', user = 'XXX', password = 'XXX', port = 5432 ) # Cursor cur = con.cursor() return con, cur def bbdd_desconnect(con, cur): cur.close() con.close() def add_new_data(): # Establecer conexión con BBDD y generar cursor con, cur = bbdd_connect() # Query - Obtenemos el id mayor junto con su fecha. query = "SELECT data_id, data_timestamp FROM Platform_App_dataerror WHERE data_id = (SELECT MAX(data_id) FROM Platform_App_dataerror);" cur.execute(query) cosa = cur.fetchall() # MIRAR LO DEL DUPLICADO if len(cosa) == 0: params = {'from':'2020-01-01 00:00'} else: params = {'uplink_id_start':cosa[0][0]} # Finalizamos la conexión con la bbdd bbdd_desconnect(con, cur) … -
Any drawbacks to a foreign key pointing to a person, not a user account?
I have a Django application that uses two simple database tables to represent users (I've simplified these a little for brevity): class Person: first_name = models.CharField() last_name = models.CharField() email = models.CharField() class User: person = models.OneToOneField('Person') last_login = models.DateTimeField(blank=True, null=True) roles = models.ManyToManyField('Role', blank=True) I pre-populate the Person table with entries from my corporate Active Directory instance, so that I can quickly reference people in our organization. User model instances are created on an as-needed basis (not every person will necessarily have a User account). This application also has various resources that need an owner (via an "owner" column in the respective tables). For example: class SomeResource: owner = models.ForeignKey('User') # ... [other fields here] ... As you can see in the example, the owner column points at the User model. I would like for the users of my application to be able to assign these resources to the necessary individual, and there is a very-real possibility that that Person's User account has not yet been created. I'm wondering: are there any general drawbacks to pointing ownership columns to the Person model instead? I realize that a few alternatives exist: Create User accounts for all Person records, whether they … -
Django create POST intermediate model
I'm using DRM v3.9.4 and have the following models: class Book(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) ... users = models.ManyToManyField("User", related_name="books", through="BookUser") class BookUser(models.Model): id = models.UUIDField(primary_key=True, editable=False) user = models.ForeignKey("User", on_delete=models.CASCADE) book = models.ForeignKey("Book", on_delete=models.CASCADE) permission = models.CharField(...) class User(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) ... with the following serializers: class UserSerializer(ModelSerializer): class Meta: model = User fields = ( "id", ... ) class BookUserSerializer(ModelSerializer): class Meta: model = BookUser fields = ('user', 'permission') class BookSerializer(ModelSerializer): users = BookUserSerializer(source='bookuser_set', many=True) class Meta: model = Book fields = ( "id", "users", ... ) extra_kwargs = { "users": {"allow_empty": True}, } When reading (GET) a Book everything is fine: { id: ..., users: [ { user: 'some-uuid', permission: 'read-only' }, ... ] } but when trying to POST using the same payload: { id: ..., users: [ { user: 'some-uuid', permission: 'read-only' }, ... ] } I get an error: KeyError: 'users' looking at the api-guide (https://www.django-rest-framework.org/api-guide/relations/) seems that by default nested serializers are read-only, but I can't make it work. BTW, IMPORTANT: all the users are (and should) already exist, so I expect this POST call to add a record in the intermediate BookUser table, and ofcourse the Book itself, … -

Django Ajax Form submit reloads after "success"

Query Django models two levels down foreign key relations
I am building a dictionary application using Django. The main models in this app are Expressions, Definitions, and Citys. The logic is that each Expression has one or more Definitions, and each Definition is associated with one City. Here is my problem: I want to query all the Citys associated with an Expression, from the Expression level. For example, I would like to do an_expression.cities and get all the Citys associated with (each Definition of) an_expression. Here are my models: class City(models.Model): city = models.CharField() class Expression(models.Model): expression = models.CharField() cities = models.ManyToManyField(City, related_name="expressions") class Definition(models.Model): city = models.ForeignKey(City, related_name="definitions") expression = models.ForeignKey(Expression, related_name="definitions") This code now works. However, every time I add a Definition I need to add the City to both the Expression --AND-- the Definition itself. Here is my question: Is there a way to only add the City to the Definition, and then somehow be able to query an_expression.cities and get all cities (basically getting rid of the cities field in the Expression model)? -
Handling data as well as response in AJAX success

If the data is my first part parameter in success Alert is displayed optimally(when certain parameters in form are not entered) but unable to display response part(when all parameters in form required are entered).

Showing a rtsp stream on React Frontend
I need to show a video stream on a react component with a Python+Django backend. CURRENT SITUATION: I'm using opencv library to get the stream: import cv2 [...] def read_data(): cap = cv2.VideoCapture("rtsp://user:password/bla bla bla") while(cap.isOpened()): ret, frame = cap.read() retval, buffer = cv2.imencode('.jpg', frame) image_result_base64 = base64.b64encode(buffer) return HttpResponse(image_result_base64, 200) On React, where this.state.response_data is the content responseText of the backend call: render () { const img_data ="data:image/png;base64," + this.state.response_data; return <img id="overView" class="overView" alt="Stream" src={ img_data} width="90%" /> } This approach works and on frontend I see the frame in my component. Unfortunally to create some sort of stream, I need to call backend at least 10 times every second to have 10fps. This is heavy to backend. I read about StreamingHttpResponse but I don't know if fits my needs. -
Markdownx does not render math formulas
i'm new here. For one month ago i have started to learn Django. My goal was to make a web app: a pool of mathematical questions.

After searching in google i have found markdownx. It renders the text and all html-tags but not mathematical formulas (see picture).example of the issue I use mathjax to render mathematical formulas.

Making password required for admins, but unusable for users
I am trying to implement a Django backend for a mobile app where users authenticate through their mobile numbers only. When the user tries to login, the backend will send him an OTP so that he can login. For this use case, I think I don't need a password field. However, I think I need a password for superusers. I am thinking of a solution but I don't know whether it is a suitable solution. models.py: class UserManager(BaseUserManager): def create_user(self, email, phone_number, password=None): user = self.model(email=email, phone_number=phone_number) user.set_password(password) user.save() return user def create_superuser(self, email, phone_number, password=None): user = self.create_user(email, phone_number, password) user.is_staff = True user.save() return user class User(AbstractBaseUser, PermissionsMixin): email = models.EmailField(blank=False, null=False, unique=True) phone_number = PhoneNumberField(blank=False, null=False, unique=True) is_staff = models.BooleanField(default=False, blank=False, null=False) objects = UserManager() USERNAME_FIELD = 'phone_number' EMAIL_FIELD = 'email' REQUIRED_FIELDS = ['email'] def __str__(self): return self.phone_number Will the code above do the job? -

How to extract csv file from a zip and save it to disk in python?
I have a zip file that I receive from the user. The zip file contains a csv file which I need to save to a directory in my server. I am using django in my backend and this is what I do from zipfile import ZipFile from django.views.decorators.csrf import csrf_exempt from django.http import HttpResponse @csrf_exempt def store_file(request): if request.method == "POST": user_id = request.POST.get("user_id") client_file = request.FILES['attachment'] file_path = "/home/sr/uploads/" try: with ZipFile(client_file, 'r') as zip_ref: csv_file = zip_ref.infolist()[0] with open(file_path + '%s' % csv_file, 'wb+') as dest: for chunk in csv_file.chunks(): dest.write(chunk) # return success message return HttpResponse(0) except Exception as e: # return error message return HttpResponse(1) But I get this error message Traceback (most recent call last): File "/home/sr/scripts/interact.py", line 2364, in store_file for chunk in csv_file.chunks(): AttributeError: 'ZipInfo' object has no attribute 'chunks' Now this is how I usually store a csv file when it comes to me as just a csv file. But now in this case, the csv file is inside a zip and so even after pulling the csv file from the zip, I can't save it in my server. What am I doing wrong?
