Django: Selenium multiple drivers (windows)
I'm creating API that is based on web-scraping via Selenium. And I've just figured out that: if user1 makes request, as long as he's waiting for response (selenium is scraping page for needed data) user2 must wait for user's1 chromedriver to stop session and only after that selenium starts scraping data for user2, that's not efficient at all ;(I'm pretty sure it's possible to run multiple drivers at the same time (one driver for each request) just like Django-channels run multiple channels. How can I achieve that? I'M NOT TESTING, I'M SCRAPING WEB-PAGES -
DRF Nested serializers
I'm kind of confused in writing the nested serializer in django rest framework. If I have tow models Account and UserProfile. In which UserProfile is ForeignKey to Account and when writing serilaizer should I call UserProfile Serializer in Account's Serializer or call Account Serilaizer in UserProfile Serializer. #Models.py Class Account (AbstractBaseUser): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) email = models.EmailField(max_length=100, unique=True Class USerProfile(models.Model): user = models.ForeignKey(Account, on_delete=models.CASCADE) address_line_1 = models.CharField(max_length=100) address_line_2 = models.CharField(max_length=100) phone = models.IntegerField(null=True) And in writing serializer I'm confused. So please explain to me in detail how to write nested serializer. #Serializers.py class AccountSerializer(ModelSerializer): class Meta: model = Account fields = ["first_name", "last_name", "email", "password"] extra_kwargs = { "password": {"write_only": True}, } class UserProfileSerializer(ModelSerializer): user = AccountSerializer() class Meta: model = UserProfile fields = "__all__" def create(self, validated_data): #Didn't write the logics here as of now. return super().create(validated_data) So Is this this correct way to write nested serializer? -

Function trigger other function and ends before result
I'm developing an API with Django Rest Framework for handling some subscriptions I wanted do make the registration in 2 steps. First, i would register user in my database, after that i want to register user to other service (email marketing, for example). I have to do it in two steps because the registering of the user in external services may take some time (or the service can be unavailable at the time of request) and i don't want users to wait everything so they can go to other pages. My idea is: After registering user into my database, i would return http 200_ok to the front-end so user can go to other pages, and in my backend i would use that data to try to register the user in external services as many times as needed (e.g: waiting if other services are unavailable). But rest_framework only allows me to return Response() (i'm using class-based views), so i only can return http 200_ok, but if i return the function ends and my other functions (that will take more time to run) will end aswell. Is there a way to do this? -

When inserting an image through tinymce in django, there is a problem with the src path of the img.

Prevent error when missing key in Django Rest Framework
I'm building an API for handling database and email-marketing data for other websites of mine. I have an endpoint for deleting users from database and ActiveCampaign, to prevent making any delete requests by mistake, i'm checking if there's a key:value pair in the request body, if 'delete': true, proceed, if not, i want to return an error message with status code for letting me (or other that i may include in project in the future) know what was the mistake. My is: While checking if there is a key named 'delete' i get an error and my program stop working. I wish to know if there's a way of only "doing stuff" after some checking, but without breaking my program, if something not expected would happen, it would send an error back to request origin. Here's the class/function i'm trying to make work: class Leads(APIView): @staticmethod def delete(request): if request.data["delete"]: delete_from_db = Lead.objects.filter(email=request.data["email"]) lead = LeadHelper(email=request.data["email"] if request.data["email"] else "") lead.delete_from_activecampaign() return Response([delete_from_db], status=status.HTTP_200_OK) else: payload = { "message": "Denied because 'delete': 'true' was not found in request, did you sent this by error?" } return Response(payload, status=status.HTTP_401_UNAUTHORIZED) My main problem is that if there's no 'delete' key, it don't … -

Import project's subpackages in Python
i'm experimenting with DDD in Python so i've decided to implement a toy project. I've created different directories in other to separate shared concepts from specific bounded contexts concepts.

Fail to pass/use string argument for img to html file in Django app?
I am very new to Django and was trying to pass one argument as a string to my html file so that I can call to use my image. I have the below code to call static image: {% load static %} <img src= "{{ user_age_pic_name }}" width=950 height=450px padding = 40px alt="" > However, this is not working (I also tried deleting the double quote). I know the image is correct because when I call <img src= "{% static 'research/used_viz/comparative/age/12-15.jpg' %}" width=950 height=450px padding = 40px alt="" > The img works perfectly. I also try to just print out the text and it seems to work fine. I think it should be cause by limited understanding of HTML arguments. Could someone guide me through this? Any input is appreciated! -
how to dynamically set the choices of a choice field in django DRF serializer through __init__ or __new__ method?

Sum using Django Template syntax?
I have an exercise that consists of sets, I assign sets to this exercise model. I am able to calculate the total volume of a single set. But how do I calculate the total volume for the exercise.

Integrating Vite (VueJs) frontend with Django Login Form
I am looking to understand how once it is checked that a user is authenticated using a django login form, how they can then be taken to a vue frontend made using vite? Many examples I have seen make use of webpack loader however, I am using vite. I am developing locally, so is it a matter of just directing the user to a local server url only if authenticated? The idea is depending on the authenticated user, certain information will need to be gathered associated with them. -

Hide specific field in drf_yasg django swagger documentation
I have a project with drf_yasg, there is a serializer with a to_internal_value method which is writing a field('mobile_operator_codes') for me. The field is overriden, so we don't need to input it in request. Though we need to output it in response. Documentation(drf_yasg) takes fields='all' and writes everything in request, though we don't need the 'mobile_operator_codes' in request blog. We don't expect it in the request.

Django forms: how to use optional arguments in form class
I'm building a Django web-app which has page create and edit functionality. I create the page and edit the pages using 2 arguments: page title and page contents. Since the edit and create code is very similar except that the edit code doesn't let you change the title of the page I want to make some code that can do both depending on the input. This is the current code I'm using right now. class createPageForm(forms.Form): page_name = forms.CharField() page_contents = forms.CharField(widget=forms.Textarea()) class editPageForm(forms.Form): page_name = forms.CharField(disabled=True) page_contents = forms.CharField(widget=forms.Textarea()) I know that if I wasn't using classes, but functions I could do something like this: def PageForm(forms.Form, disabled=False): page_name = forms.CharField(disabled=disabled) page_contents = forms.CharField(widget=forms.Textarea()) PageForm(disabled=True) PageForm(disabled=False) That is the kind of functionality I'm looking for^^ I tried the following: class PageForm(forms.Form): def __init__(self, disabled=False): self.page_name = forms.CharField(disabled=disabled) self.page_contents = forms.CharField(widget=forms.Textarea()) class PageForm(forms.Form, disabled=False): page_name = forms.CharField(disabled=disabled) page_contents = forms.CharField(widget=forms.Textarea()) Both didn't work and got different errors I couldn't get around. I was hoping someone could lead me in the right direction, since I'm not very familiar with classes.
