Django All_auth/rest_auth e-mail address validation using HTTP GET request
I use Django all_auth and rest_auth for a backend service of a mobile app. I integrated the registration and login API and all works fine. Now I have to integrate the e-mail address validation logic. After the registration (without social), I have to send an e-mail with the link that the user will use to validate your account. I added this configurations into my Django settings: ACCOUNT_EMAIL_VERIFICATION = 'mandatory' SOCIALACCOUNT_EMAIL_VERIFICATION = 'none' Also this works fine. I'm able to receive the e-mail after the registration of a new account. In the received e-mail I have the link to validate the account also. I would like to have the validation of the e-mail when the user simply will click on the link. So, I would like to use only the GET HTTP method. I added, as suggested into the documentation, this setting also: ACCOUNT_CONFIRM_EMAIL_ON_GET = True I use this url linked to the all_auth views. But, if I try to click on the link from the received mail, I obtain this error: KeyError at /account-confirm-email/NzU:1hjl8A:z5Riy8Bjv_h0zJQtoYKuTkKvRLk/ 'key' /allauth/account/views.py in get self.object = self.get_object() ... ▶ Local vars /allauth/account/views.py in get_object key = self.kwargs['key'] ... ▶ Local vars This seams that setting is … -
DJANGO Queryset filter according to inner calculations on nested model

How can you make a django model which can be displayed on the main page and not on admin page
i'm just doing some studying regarding django and finished a crashcourse on django, in the crashcourse he only showed how to display a Model on the admin page but what if I want a user to use the model and not specifically a admin? E.g what if I want anyone that visits /todo/ to be able to add a todo and not make the todo only be addable by the admin panel. -
Event listener works in on context but not another - code identical, and no errors observed. Possible causes?
I'm bamboozled. I use a select2 widget on a web page, implemented by django-autocomplete-light, and I attach an event listener to the it as follows: const game_selector = $("#"+id_prefix+"game"); game_selector.on("change", switchGame); Works a charm. I select a new game in the select box and the switchGame function is called. That is running on Django development server with manage.py runserver. And I can see how groovy this is in Chrome's debugger: There it is, switchGame(event) is the handler. And it all works too. No drama. But I publish the code to my webserver and suddenly it doesn't work. The event listener never fires. switchGame is never called. It's serving the self same code, looks the same in the client and in Chrome's debugger. All fine. I can even see the event listener is attached, albeit the order is different: Severed by the development server there there is a select2 handler above switchGame in the list and served from the production server the same select2 handler is listed below the switchGame handler. Can the order matter? And why would the order differ? In the end I am looking at the same binding code above, and I can set a breakpoint inside switchGame … -
I want to include Email in signup.html so that users can request to reset password in password_reset_form.html
I was creating a Login Page using Django through a tutorial. While signing up first time through "py manage.py createsuperuser" it asked for email. Than i created the password reset page, and the signup.html page. When i reset a password it sends email to the registered email of my email. When i created a user in the signup.html, it did not ask for email. How would i code it to ask for email so that we can use the password reset option for every user. -

Do websockets send and receive full messages?
I am new to web development and I am trying to write a simple web game using python and django for my server with some javascript for the front end graphics. I am using the channels package to use websockets for the communication and I have a little question about websockets. In python, I know that when we use sockets, the message isn't guaranteed to be sent fully. For example, if I use socket.send in python, I may not send the entire message and in that case I need to resend what is left, and on the receiving side, I am not guaranteed to get the full message using socket.recv (assuming the bufsize argument is big enough for the full message), so I have to keep calling recv until I get the entire message. My question is: Is it the same with websockets or not? I tried looking for this in the MDN docummentation and in google, but I couldn't find any information on this. In addition, every example I have seen online didn't take this into account, so it seems like what I send with socket.send (in javascript) is exactly what I get on the other end and vice … -

Change subprocess Popen from file to `Django InMemoryUploadedFile`
I have a function that require filename as an input argument and return list of str. import subprocess def get_length(filename: str) -> typing.List[str]: result = subprocess.Popen(["ffprobe", filename], stdout=subprocess.PIPE, stderr=subprocess.STDOUT) return [x.decode('utf-8') for x in result.stdout.readlines() if "Duration" in str(x)] In the Django application. I use it with InMemoryUploadedFile. My quick solution is write down a file to disk and read it to the function. Question: Is it possible to let my get_length() read from the InMemoryUploadedFile rather than physical file`? -
Django rest "this field is requiered" on a many to many field when blank=True
I have an object I would like to be able to make via django-rest-api UI. This object has a manytomany field that holds other objects on it. Even though that field is blank param is set to True, I get a response that "this field is requiered". class Post(models.Model): title = models.CharField(max_length=100) slug = models.CharField(max_length=200, null=True) description = models.CharField(max_length=200, null=True) content = HTMLField('Content', null=True) black_listed = models.ManyToManyField('profile_app.Profile', related_name='black_listed_posts', blank=True) score = models.PositiveIntegerField(null=True, default=0, validators=[MaxValueValidator(100)]) serializers.py: class PostSerializer(serializers.HyperlinkedModelSerializer): black_listed = ProfileSerializer(many=True) read_only = ('id',) def create(self, validated_data): self.black_listed = [] class Meta: model = Post fields = ('id', 'title', 'slug', 'description', 'content', 'black_listed', 'score') views.py: class PostViewSet(ModelViewSet): serializer_class = PostSerializer queryset = Post.objects.all() lookup_field = "slug" def create(self, request, *args, **kwargs): serializer = self.get_serializer(data=request.data) serializer.black_listed = [] if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) As you can see, i tried overriding the create() method on both serializer and viewset, but that didnt work and still gave me that the black_list field is requiered. What i expected that if the field is not required in the db, then the serializer can set it to None on the creation what am i missing here? -

Dynamic updates in real time to a django template
I'm building a django app that will provide real time data. I'm fairly new to Django, and now i'm focusing on how to update my data in real time, without having to reload the whole page. Some clarification: the real time data should be update regularly, not only through a user input. View def home(request): symbol = "BTCUSDT" tst = client.get_ticker(symbol=symbol) test = tst['lastPrice'] context={"test":test} return render(request, "main/home.html", context ) Template <h3> var: {{test}} </h3> I already asked this question, but i'm having some doubts: I've been told to use Ajax, and that's ok, but is Ajax good for this case, where i will have a page loaded with data updated in real time every x seconds? I have also been told to use DRF (Django Rest Framework). I've been digging through it a lot, but what it's not clear to me is how does it work with this particular case. -

Django + Docker best practice: use runserver or wsgi.py?
I've been reading a lot of blog posts (like this one) on how to deploy Django in a containerized Docker environment. They all use the runserver command in the docker-compose.yml. Even the Docker documentation does this. This suprises me, since using the Django web server is not recommended for production! What is recommended is pointing the webserver to wsgi.py. However, none of the articles I've found on Django and Docker explain why they use runserver instead of pointing apache or nginx to wsgi.py. Why would all these articles use the built-in Django development webserver to handle requests, instead of a full blown webserver like apache or nginx? Isn't the point of using containers in development, to keep that environment as close to production as possible? Then why build a not-production-ready environment? -
