How can I replace Email with Phone Number in Django Rest Framework's Forgot Password Module
I have developed an app using ReactJS and Django Rest Framework. Problem: For Forgot Password functionality, we're using the built in module which requires email. The link is propagated to the given email. I want to do this via phone number only. Is it possible? -
How to display data from parent model using foreign key django
I want to display the child model data with the parent model data as well in a queryset. This is my models in model.py class Shareholders(models.Model): sharehold_IC = models.CharField(primary_key=True, unique=True, validators=[RegexValidator(r'^\d{12,12}$'), only_int], max_length=12) sharehold_name = models.CharField(max_length=100, null=True) sharehold_email = models.CharField(max_length=50, null=True, unique=True) sharehold_address = models.TextField(null=True, blank=True) password = models.CharField(max_length=100) def __str__(self): return self.sharehold_name class Meeting(models.Model): MEETING_STATUS = ( ('Coming Soon', 'Coming Soon'), ('Live', 'Live'), ('Closed', 'Closed') ) meeting_ID = models.CharField(primary_key=True, max_length=6, validators=[RegexValidator(r'^\d{6,6}$')]) meeting_title = models.CharField(max_length=400, null=True) meeting_date = models.DateField() meeting_time = models.TimeField() meeting_desc = models.CharField(max_length=500, null=True) meeting_status = models.CharField(max_length=200, null=True, choices=MEETING_STATUS) date_created = models.DateTimeField(default=timezone.now, null=True) def __str__(self): return self.meeting_ID class Question(models.Model): question_ID = models.AutoField(primary_key=True) question = models.CharField(max_length=400, null=True) meeting_id = models.ForeignKey(Meeting, on_delete=CASCADE) shareholder_IC = models.ForeignKey(Shareholders_Meeting, on_delete=CASCADE, related_name='shareholder_ic') date_created = models.DateTimeField(default=timezone.now, null=True) def __str__(self): return str(self.meeting_id) I try to display all the data from the Question model with the shareholders details such as sharehold_name from the Shareholders model.

Django slider widget default value
Using django I have implemented a slider for a form, that is presented as part of a formset so as to enable users to add additional rows using jquery. My issue is that although the model has the default value as ‘0’, and this is what the first row displays, when I add additional rows the slider is at the midpoint (’50’).

Django route giving 404
I've got a route registered in the urls.py file of my django main app as: router.register(r"visual/(?P<random_url>[\w]+)/$", views.LinkTest, basename="test") and the url patterns defineded as: urlpatterns = [ # Admin path("admin/", admin.site.urls), # Model API Routes path("rest/api/latest/", include(router.urls)) ] which means I should be able to hit the viewset via the following call http://localhost:8000/rest/api/latest/visual/random_string/ but I'm getting a 404 Can anyone tell me what I'm doing wrong? -
The one line if else elif not working in Django
After referring to this answer Tim Pietzcker, I implemented that code on my website. I'm not getting the proper solution for the same. Well, I try to implement if elif and else statement in one line Django. So I have tried this. views.py cart1 = CartTube.objects.values_list('tube__tubecode', flat = True) cart2 = CartDrum.objects.values_list('drum__drumcode', flat = True) machine = Machine.objects.filter(tubecode__in=cart1) if cart1 else Machine.objects.filter(drumcode__in=cart2) if cart2 else Machine.objects.filter(Q(tubecode__in=cart1) & Q(drumcode__in=cart2)) if cart1 else Machine.objects.all().order_by('id') Well, From the above code I'm trying to find a solution: If the user chooses Drum as a product then the same code should match with Machine and filter the exact matching product. and if, Drum product + Tube product is chosen then show the exact combination product from the Machine Since the individual code works perfectly. Down below are the code work perfectly. ✔️ machine = Machine.objects.filter(tubecode__in=cart1)if cart1 else Machine.objects.all().order_by('id') ✔️ machine = Machine.objects.filter(drumcode__in=cart2) if cart2 else Machine.objects.all().order_by('id') ✔️ machine = Machine.objects.filter(Q(tubecode__in=cart1) & Q(drumcode__in=cart2)) if cart1 else Machine.objects.all().order_by('id') Tell me where I'm going wrong -

(Django Rest Framework) got an error when I used RefreshToken class in rest_framework_simplejwt.tokens
I got an error which is related to RefreshToken class implemented in rest_framework_simplejst. I defined a function: def get_tokens_for_user(user): refresh = RefreshToken.for_user(user) return { 'refresh': str(refresh), 'access': str(refresh.access_token)} when I made a request to the server that is in the development environment, it ran perfectly: "POST /account/signup HTTP/1.1" 200 332 but when I made a request to the server that is in the production environment, it ran poorly: Forbidden: /account/signup I try to debug it and find the breaking point is "refresh = RefresgToken.for_user(user)", when I printed "refresh", it got the same result mentioned before and jumped to the exception block. Forbidden: /account/signup /account/signup is the endpoint that calls the function "get_tokens_for_user". Can anyone explain what is going on and why the production and development environment make the difference? Thanks so much. -

Django translation system
I have a small problem that I can't solve. With reference to Django's automated translation system, I wanted to do a teaching test: I went to django / contrib / auth / models.py in the AbstractUser class and in line 340 (Django version 3.2.7) I changed _ ('first name') to _ ('dog') then I went to the django.po file located in django / contrib / auth / locale / it / django.po and there I inserted a new reference, that is: msgid "dog" msgid "cane" i saved and restarted the server.

Why are script tags auto converting & to &?
I'm experiencing a strange problem I haven't run into before. My html is generated via Django templates, and consist of some basic code that initializes a DataTable based on a query string with some GET variables (i.e. "/report1/?filter1=abc&filter2=def"). However, all of a sudden, whenever I write the Django template variable out within a <script></script> tag the & is converted to &amp;, like this: <script> var link = "/report1/?filter1=abc&amp;filter2=def" </script> However, when not inside a script tag, the string outputs as originally intended: "/report1/?filter1=abc&filter2=def" This is based off the exact same Django template variable with no changes. What about the script is causing the & to be encoded? This happens in current versions of Edge and Firefox. Django clearly doesn't know anything about the <script></script> tags so it must be a browser thing. Any ideas how to prevent this from happening? It is something that didn't seem to happen in the past. Thanks! For reference, my Django template looks something like this: {{ string }}<br> <script> var link = "{{ string }}" </script> -
Normalize CRLF line endings in Django form input
I have a ModelForm with a TextArea. If the user submits text with a newline, it gets converted into a \r\n by the browser. I would expect Django to normalize this text for me, but it doesn't. This is an issue because Django's maxlength validation doesn't line up with the maxlength in HTML, since in-browser lines endings are treated only as "\n". So if the textarea has a maxlength of 5, and the user enters "ab\ncd", they think that's fine, but when they submit the form, Django error because it sees "ab\r\ncd", which is 6 characters. I want to fix this by doing everything with \n, and not save \r\n into the database. -
Django Class Model choices from json file
When creating class in Django, why upload from json file instead of entering CHOICES directly? Is it not stored as a string in the Database, but as a 'pk' to relieve the burden on the DB?
