django form.is_valid returns false when while using XMLHttpRequest
since bootstrap 5 no longer ships with jquery and recommends using the vanilla javascript XMLHttpRequest() to make dynamic requests that is what I am trying to do in django. All the other examples of doing this use the traditional .$ajax. I have a basic javascript function: function sendPhoneVerification(_phone) { var http = new XMLHttpRequest(); const params = { phone: _phone } http.open('POST', '/approvephone/', true) http.setRequestHeader("X-CSRFToken", "{{ csrf_token }}"); http.setRequestHeader('Content-type', 'application/json') http.setRequestHeader('phone', _phone) http.send(JSON.stringify(params)) http.onload = function() { alert(http.responseText) } } The CSRF middlware token is working fine, but the in the view, the form.is_valid() returns false and the error is that required field "phone" is missing. I can't tell how I am supposed to provide that value. The form being tested against is a simple form with one field class AddPhoneForm(forms.Form): phone = PhoneNumberField() relevant part of the view @csrf_protect @login_required def approvephone(request): if request.method == 'POST': form = AddPhoneForm(request.POST) if form.is_valid() #returns false and error is missing field "phone" Any idea how I can correctly provide the phone fields in the POST response to make django happy? -

Trobles to load a partial for a dependent drop-down list in a Django template
I'm trying to implement a dependent drop down list between countries and cities, but the document responsible to load the cities doesn't load. I'm trying to solve this problem since 3 days and I don't get a clue. The database has no problem because I tested it with non-ajax requests. And it is not a database problem, because the entire partial doesn't load. The most probable cause of the problem is that I based some code on online tutorial which probably use old versions either of JQuery or Django. But, here's the code Models.py from django.db import models class Country(models.Model): class Meta: db_table = 'countries' name = models.CharField(max_length=300) def __str__(self): return self.name class City(models.Model): class Meta: db_table = 'cities' name = models.CharField(max_length=300) state_id = models.BigIntegerField(null=True) country = models.ForeignKey(Country, on_delete=models.CASCADE) def __str__(self): return self.name class Person(models.Model): class Meta: db_table = 'people' name = models.CharField(max_length=300) birthdate = models.DateField(null=True, blank=True) country = models.ForeignKey(Country, on_delete=models.SET_NULL, null=True) city = models.ForeignKey(City, on_delete=models.SET_NULL, null=True) def __str__(self): return self.name Forms.py from django import forms from .models import Person, City class PersonForm(forms.ModelForm): class Meta: model = Person fields = ('name', 'birthdate', 'country', 'city') """ right now we are overriding the default init method, and setting the queryset of the … -

Django Form not updating data in the model
this is my first Django project and I am stuck. If not a solution, but just a hint on what I am doing wrong will be truly appreciated. I have a model with one attribute set as Null by default and I want to use a Form to update that attribute with the ID taken from another model.

How do I access instance of a many-to-many field in django __str__ method

Test with customized auth_user model
I have a customized auth_user model in my application name "test-app".
