dj-rest-auth Reset email link keeps pointing to the backend
I'm using dj-rest-auth with react and i'm trying to use the frontend url instead of the backend url. The solution i am using for the account creation confirmation email affects the reset password email too but only partially. It does not effect the port. It only tries to add a key to the reset link where there is none and throws me an error. So i was wondering if there is a way to change the url from port 8000 to port 3000. This is what i have tried: class AccountAdapter(DefaultAccountAdapter): def is_open_for_signup(self, request: HttpRequest): return getattr(settings, "ACCOUNT_ALLOW_REGISTRATION", True) def send_mail(self, template_prefix, email, context): if settings.DEBUG: context["activate_url"] = ( "http://localhost:3000/accounts/confirm-email/" + context["key"] ) else: context["activate_url"] = ( settings.FRONTEND_URL + "/accounts/confirm-email/" + context["key"] ) return super().send_mail(template_prefix, email, context) If i get rid of the key part it doesn't give me an error but keeps port 8000 and breaks my account confirmation emails. If i don't get rid of the key it gives me: django | "http://localhost:3000/accounts/confirm-email/" + context["key"] django | KeyError: 'key' -
Django contenttypes follow/unfollow
Trying to use contenttypes to store following relations of users. I can create a follow, but I can't remove a follow from the database. Model Code accounts app ------------ from activities.models import Activity class CustomUser(AbstractUser): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) follow = GenericRelation(Activity) activities app -------------- class Activity(models.Model) FOLLOW = 'F' LIKE = 'L' ACTIVITY_TYPES = [ (FOLLOW, 'Follow'), (LIKE, 'Like'), ] ## stores the user_id of the Liker/Follower user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) ## stores 'F' or 'L' activity_type = models.CharField(max_length=2, choices=ACTIVITY_TYPES) date = models.ForeignKey(ContentType, on_delete=models.CASCADE) ## stores CustomUser id of the user who is followed or the id of the post that is liked object = models.UUIDField(null=True, blank=True, db_index=True) content_object = GenericForeignKey('content_type', 'object_id') class Meta: indexes = [models.Index(fields=["content_type", "object_id"]),] View Code follower = User.objects.get(id=follower_id) followed = User.objects.get(id=followed_id) ## This is the contenttypes model a = Activity.objects.filter(user=follower.id, object_id=followed.id) ## This is my janky way of checking whether the follower is already following the followed if len(a) == 0: ## This works to create a follow followed.follow.create(activity_type=Activity.FOLLOW, user=follower) I thought this might work to delete the follow followed.follow.remove(a) but it gives me an error 'QuerySet' object has no attribute 'pk' -

Registration data "lost" somewhere in python django 4
I have my super basic authentication app, and I tried to write a simple Registration with email, first name, last name and (logically) password, but it seems that when I enter my request data it is "lost" somewhere. When I press the "POST" button, all the fields are blank and it says: "This field is required". I've been trying to figure it out for quite a long time, but I am new to django.

DRF serializer's BooleanField returns null for empty ForeignKey field

"has_video": null, "has_gallery": null, I try to set allow_null parameters to false but the result is the same (the values are still null). has_video = serializers.BooleanField(source='video', default=False, allow_null=False) has_gallery = serializers.BooleanField(source='gallery', default=False, allow_null=False) When the video or gallery is not null, the serializer's fields return true as I expect.

python framework for trading robot
I want to create a web application for trading. Front - React Backend - Python I can't decide which Python framework to choose. Backend should accept a request from the front, make a request to a third-party API and return its response to the front. Also, there is analytics module on the backend, which performs operations with data from API and front and sends requests to API too. A heavy load is assumed and the speed of work is critical for the application. I don't need a lot of models and admin panel. I choose between django, flask, FastApi, but if there are other frameworks for this task, I will be glad to hear. What would you recommend? Interested in the simplest solution to these problems. -

Wagtail panel for self-referential many to many relationships with a through model
I am busy making something like a knowledge graph in wagtail. CurriculumContentItem is a node on that graph. It has a many-to-many relationship with itself, and the through model has important fields. I'm struggling to get this to be usable in the admin page. Please see the inline comments: class ContentItemOrder(models.Model): post = models.ForeignKey( "CurriculumContentItem", on_delete=models.PROTECT, related_name="pre_ordered_content" ) pre = models.ForeignKey( "CurriculumContentItem", on_delete=models.PROTECT, related_name="post_ordered_content" ) hard_requirement = models.BooleanField(default=True) class CurriculumContentItem(Page): body = RichTextField(blank=True) prerequisites = models.ManyToManyField( "CurriculumContentItem", related_name="unlocks", through="ContentItemOrder", symmetrical=False, ) content_panels = Page.content_panels + [ # FieldPanel("prerequisites") # FieldPanel just lets me select CurriculumContentItems, but I need to access fields in the through model # InlinePanel("prerequisites"), # This causes a recursion error FieldPanel('body', classname="full collapsible"), ] If I wanted to do this in the normal Django admin I would make use of an inlines to specify prerequisites. Something like: class ContentItemOrderPostAdmin(admin.TabularInline): model = models.ContentItem.prerequisites.through fk_name = "post" class ContentItemOrderPreAdmin(admin.TabularInline): model = models.ContentItem.unlocks.through fk_name = "pre" Is there a similar mechanism in Wagtail? It looks like I need to create a custom Panel for this. -

Populate selectbox after div show with columns from a pandas dataframe
So, I have a html form which, after submit, populates some selectboxes with rows values form a pandas dataframe. I have added a jquery script in order to hide the selectboxes before submit and show after submit , but the selectboxes are not being populated anymore as before. For sure something is missing but unfortunately I am pretty new to js and jquery. This is my script: $(document).ready(function(){ $("#myform").submit(function(e) { e.preventDefault(); $("#second").show(); }); This is my html: <form method = "POST" action ="dashboard" id="myform"> {% csrf_token %} <select name="line"> <option value=" 1" selected="selected"> 1</option> <option value=" 2">2</option> <option value=" 3">3</option> <option value="All">ALL</option> </select> Line <select name="data"> <option value="weekly" selected="selected">weekly</option> <option value="monthly">monthly</option> </select> Data <input type="submit" value="Select"> </form> </div> <div id = "second" style="display:none"> <br><br><br> <select class="position"> {% for pos in posnr %} <option value="{{ pos }}">{{ pos }}</option> {% endfor %} </select> <select class="x"> {% for pos in posnr %} <option value="{{ pos }}">{{ pos }}</option> {% endfor %} </select> <select class="y"> {% for pos in posnr %} <option value="{{ pos }}">{{ pos }}</option> {% endfor %} </select> </div> This is part of a django project , the view part is working well -

I use Django Channels and I have multiple websocket addresses. When I connect to a websocket, it gets and computes somethings from database and this process may take 10 seconds. But during this 10 seconds all of my websockets does not respond to any user and it yields a 502 Bad Gateway to every user. It seems that all of my websockets are running by a single agent, and when it is pending, all other websockets does not respond anymore, until the agent becomes free. My code is some like the following code. How can I solve this problem? class SymbolConsumer(WebsocketConsumer): def connect(self): self.symbol_name = self.scope["url_route"]["kwargs"]["symbol_name"] async_to_sync(self.channel_layer.group_add)(self.symbol_name, self.channel_name) self.accept() self.send(time_consuming_function_1(self.symbol_name)) self.send(time_consuming_function_2(self.symbol_name)) def disconnect(self, close_code): async_to_sync(self.channel_layer.group_discard)( self.symbol_name, self.channel_name ) def receive(self, text_data): pass -
