Django Channels Change HTML/Javascript For Everyone
I want to make it so if a user disconnects from the websocket their status will change to "offline" for everyone that is viewing the user's profile page. I have successfully done so for detecting when users are online but using the same code for disconnecting doesn't work. How should I go about doing this? Here's the code for the Javascript activityWS.onmessage = function(event) { var parsedDict = JSON.parse(event['data']); profileUrl = window.location.origin + '/account/' + parsedDict['user'] + '/'; if (window.location.href == profileUrl) { $('.online-status').text('Online'); } } $(window).on('beforeunload', function(event) { // won't change to offline but online changing works if (window.location.href == profileUrl) { $('.online-status').text('Offline'); } }); -
Cannot log in to token endpoint with username/password: drf token auth and custom user model, Django
I have a basic Django app using Django rest framework, a custom user model inheriting from the default, and basic token authentication. I am able to generate a token for any user by running python3 ./manage.py drf_create_token {USERNAME/EMAIL} and authenticate relevant requests with it. However, when I attempt to hit my token endpoint (in this case http://127.0.0.1:8000/api/token/, or the equivalent for the deployed app), I get { "non_field_errors": [ "Unable to log in with provided credentials." ] } My request body (application/json) is like: { "username": "test@test.com", "password": "test" } I have ensured that the user is active; that the password is correct; and that the username is the same as the email. My custom user class: class Customer(AbstractUser): first_name = models.CharField(max_length=240) last_name = models.CharField(max_length=240) email = models.EmailField(unique=True) phone_number = PhoneNumberField(unique=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now_add=True) is_active=models.BooleanField(default=True) USERNAME_FIELD = "email" REQUIRED_FIELDS = ["password", "phone_number", "first_name", "last_name", "username"] def __str__(self): return f"{self.first_name} {self.last_name}" relevant urls: urlpatterns = [ path('admin/', admin.site.urls), path('api/users/', include('customer.urls')), path('api/token/', obtain_auth_token, name="auth_token"), ] in settings.py I have the following: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django_extensions', 'phonenumber_field', 'customer', 'contact', 'rest_framework', 'rest_framework.authtoken', ] ...

Django import existing Ppasswords from PHP site that used password_hash()
I need to import a list of users and hashed passwords from an old PHP site that used password_hash() to a new django site. The stored passwords look like this: $2y$10$ZnxKDPbqOfACnGmQeN76o.UtdwWBFBCCLTiGnvCSvl/zqIBeVxhai I found Django password hasher using php format of function password_hash() on here when trying to look this up, and I think that will help for the NEXT step. But currently I can't setup an import process that will correctly bring over the old passwords. When I try to manually create the users during the import process it refuses the password stating "Invalid password format or unknown hashing algorithm." when I look at the users after the import runs. I think I am just going about this totally incorrectly, here is an example snippet where I create the users. usertest = User(username='testguy',email='testguy@test.com',password='$2y$10$ZnxKDPbqOfACnGmQeN76o.UtdwWBFBCCLTiGnvCSvl/zqIBeVxhai') That results in no password being store. Using the create_user function results in the user being created but with that hashed password output as their password: User.objects.create_user(username='testguy',email='testguy@test.com',password='$2y$10$ZnxKDPbqOfACnGmQeN76o.UtdwWBFBCCLTiGnvCSvl/zqIBeVxhai') How can I just get these passwords stored properly in the new database so I can move onto the next step of actually checking against those passwords? -
is it possible to customize e.g an app model field with html/css
I have this model field that holds the description(image from django-admin) but when I print it out on the page it looks like the following(image from django-admin): enter image description here so is it possible to edit the description field so it looks better and is more readable using html/css etc? -
what's the most efficient way to check for orphans when deleting objects in Django?
Say I have a model with a Things table and a table of relationships between the things called ThingRelations. It should not be possible to delete a Thing when there are ThingRelations that point to it, and when there are no more ThingRelations pointing to a given Thing, it should be deleted. I'm currently trying to implement that with signals.post_delete like this: from django.db import models class ThingRelation(models.Model): first_thing = models.ForeignKey('Thing', on_delete=models.PROTECT) second_thing = models.ForeignKey('Thing', on_delete=models.PROTECT) class Thing(models.Model): name = CharField(max_length=260) @receiver(models.signals.post_delete, sender=ThingRelation) def check_relation_and_delete(sender, instance, *args, **kwargs): for thing_id in [instance.first_thing, instance.second_thing]: first_thing_match = ThingRelation.objects.filter(first_thing=thing_id).exists() second_thing_match = ThingRelation.objects.filter(second_thing=thing_id).exists() if not first_thing_match and not second_thing_match: Thing.objects.get(pk=thing_id).delete() Is this the most efficient way to find and delete orphaned Things? I'm very new to databases in general, but won't filtering the (potentially quite large) Things table four times for every deleted ThingRelation be slow when deleting many objects at once? Is there some kind of SQL or Django functionality that makes it so this code isn't run for every object in a bulk operation? -
Django allauth password reset doesn't work when clicking the link from email, but works otherwise
What is supposed to happen: The request is completely handled by the django-allauth package which is supposed to detect the token, save it to the session, redirect to the 'change your password' page, and finally load the token from the session. The problem: The password reset function does not work when clicking the link from the email (Bad Token), but if I copy-paste the link into the url bar or click the href in Inspect Element mode it DOES work. Note: It also works if I reload the page after seeing "Bad Token" I click the link from inside an email app on my mobile device The error: When you click the link from your email you make it all the way to the 'change your password' page but you get a "Bad Token" error as no Token was found in the session. Format of the link emailed to the user: <a href="https://subdomain.url.com/ls/click?upn=DEcd6nIgEEAvb4Zt..." rel="noreferrer" safedirecturl="https://www.google.com/url?q=https://sudomain.url.com/...">link text</a> For clarification, both the href and the safedirecturl work fine if I copy-paste it into the url bar Conclusion: So far, these are my only guesses at the cause of the issue: An external website is referring the user to the page. The safedirecturl … -
how do I manage deletion with multiple foreign keys to the same table in Django?
Say I have a model with a Things table and a table of relationships between the things called ThingRelations. It should not be possible to delete a Thing when there are ThingRelations that point to it. This is how I'm trying to implement that: from django.db import models class ThingRelation(models.Model): first_thing = models.ForeignKey('Thing', on_delete=models.PROTECT) second_thing = models.ForeignKey('Thing', on_delete=models.PROTECT) class Thing(models.Model): name = CharField(max_length=260) How do I automatically delete a Thing when there are no more ThingRelations pointing to it? -

ajax problem with Django {{ form|crispy }} vs. {{ form.as_p }}
I have a set of dependent dropdowns that depend on the ajax function to work. The ajax works fine with {{ form.as_p }} but it seems never fire when I replace {{form.as_p}} with {{form|crispy}} . As you can see in my html, the only difference is in which one is commented out. {% extends "base.html" %} {% load tailwind_filters %} {% block content %} <div class="max-w-lg mx-auto"> <a class="hover:text-blue-500" href="{% url 'leads:lead-list' %}" >返回客户名单</a > <div class="py-5 border-t border-gray-200"> <h1 class="text-4xl text-gray-800">{{lead.name}}</h1> </div> <form id="leadForm" method="POST" class="mt-5" enctype="multipart/form-data" data-cities-url="{% url 'leads:ajax_load_cities' %}" novalidate> {% csrf_token %} {{ form|crispy }} {% comment %} {{ form.as_p }} {% endcomment %} <div class="flex py-6 "> <a href="{% url 'leads:lead-delete' lead.pk %}" class="flex ml text-white bg-indigo-200 border-0 py-2 px-6 focus:outline-none hover:bg-indigo-600 rounded-md"> Delete</a> <button type='submit' class=" ml-auto text-white bg-blue-500 hover:bg-blue-600 px-6 py-2 rounded-md"> Submit </button> </div> </form> </div> <script src="https://code.jquery.com/jquery-3.3.1.min.js"></script> <script> $("#id_region").change(function () { //var dateNow = new Date().getTime() + Math.random(); var url = $("#leadForm").attr("data-cities-url"); var regionId = $(this).val(); $.ajax({ url: url, data:{ 'region': regionId }, success: function (data){ $("#id_city").html(data); } }); }); </script> {% endblock %} -

Using Django's Bulk Update Correctly to Append to List
I have a dictionary list of items in validated_data which I currently update the user and save to db. for book in validated_data: book.user = self.context['request'].user obj.save() I would like to make use of Django's bulk update instead. I found the following example: Which I modified like so: for book in validated_data: book.user = self.context['request'].user Book.objects.bulk_update(validated_data, update_fields = ['user']) However, I don't see how this can work.

Django: Inherit class with API Data
I want to ask the user for a password in my first view and in the other views use this password to show data on the frontend. So far I just saved the password in a session and I instantiated the API every time I clicked on another view. What I want is to save the state of that API call (for example the token) in this class.

I have this html code snippet: <td><button value="{{i.0}}" type="button" onclick="setEndActivity({{i.0}}, '{{i.1}}', '{{i.8}}', '{{i.10}}', '{{i.4 | 'date:Y-m-d H:m:s'}}')">End</button></td> I'd like to escape single quotes here: 'date:Y-m-d H:m:s' . Even better to create better mask to ISO format.
