Hi i'm using ModelFieldChoice to set the foreign key from Provider in the model "Article" (Article belongs to Provider). The select in the template is displayed correctly with all the providers from the database, but when i try to post the form, it throws an error that the select value is required even if i'm passing it. Also i seted values for the article in the database, and when i tried to edit it, all the fields in the form are populated with the correct data except for the select.
These are my models, i would appreciate the help, thanks! Sorry if i'm doing something wrong, this is my first time posting in stackoverflow.
Article.py Model
class Article(models.Model):
codigo = models.CharField(max_length=100, verbose_name='Codigo')

print(request.POST['proveedor_id'])
if create.is_valid():
create.save()
return redirect('/dashboard/articles/?add=success')
else:
print(create.errors)
return redirect('/dashboard/articles/?error=True')
else:
return render(request, "article/add_edit_article.html", {'editMode': False,'form': ArticleCreate})
In views.py when i print 'proveedor_id' the value is correctly displayed in console but then the "is_valid()" fails and it prints the error "<ul class="errorlist"><li>proveedor<ul class="errorlist"><li>Este campo es obligatorio.</li></ul></li></ul>" (obligatory field, as if i'm not passing it)
First, simplify your ArticleCreate serializer to be like this:
class ArticleCreate(forms.ModelForm):
class Meta:
model = Article
Then in the request pass proveedor field, not proveedor_id. In Django/DRF you should pass association IDs using "{{association_name}}": id pattern, not "{{association_name}}_id": id
Sou you can simplify your view as well:
def add_article(request):
if request.method == 'POST':
create = ArticleCreate(request.POST)
if create.is_valid():
create.save()

So, I was studying Django and started doing some projects to fixate what I learned.
I'm building a contact book like website and want to make each user have a unique Contacts table.
I've tried putting this on models.py:
class UserContatos(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
class Contato(models.Model):
nome = models.CharField(max_length=255)
sobrenome = models.CharField(max_length=255, blank=True)
telefone = models.CharField(max_length=255)
email = models.CharField(max_length=255, blank=True)
data_criacao = models.DateTimeField(
default=timezone.now)
descricao = models.TextField(blank=True)
categoria = models.ForeignKey(Categoria, on_delete=models.DO_NOTHING)
mostrar = models.BooleanField(default=True)
foto = models.ImageField(blank=True, upload_to='fotos/%y/%m/%d')
def __str__(self):
return self.nome
contatos = Contato()
class ContatoForm(forms.ModelForm):
class Meta:
model = UserContatos.Contato
exclude = ('',)
When I use this form to create a contact, it doesn't "go to the user".
I'm have been struggling on this for 2 days, really. I want to populate Timesheet form field from Employees model as a select field / dropdown list.
Here are my files and I tried so far.

I am getting a (RelatedObjectDoesNotExist: UserProfile has no site) error in one of my views yet I am able to perform all CRUD operations in the admin with out any errors.
django.db.models.fields.related_descriptors.RelatedObjectDoesNotExist: UserProfile has no site.
Excerpt from models.py
class Sites(models.Model):
name = models.CharField(max_length=255, blank=True, null=True)

account_type = models.CharField(max_length=255, blank=True, null=True)
def __str__(self):

return site_str
class Meta:
managed = True
db_table = 'sites'
class UserProfile(models.Model):
user = models.OneToOneField(settings.AUTH_USER_MODEL,
on_delete=models.CASCADE)
site = models.ForeignKey(Sites)
def __str__(self):
user_profile_str = '{}: {}'.format(self.user.username, str(self.site))
return user_profile_str
Excerpt form views.py
#login_required
def client_list(request):
user_profile = UserProfile(user=request.user)
print(user_profile.user.username)
clients = Clients.objects.filter(site_rec=user_profile.site)
return render(request, 'snapreport/clients/all_clients.html', {'clients': clients})
In this line: user_profile = UserProfile(user=request.user) you're creating a new UserProfile for the user. And since you don't assign it a site, user_profile.site is None (or trying to access it throws RelatedObjectDoesNotExist).
You probably want:
user_profile = UserProfile.objects.get(user=request.user)
if the profile already exists (assuming that will have a site).
I have two models as follows :
class FlightSchedule(models.Model):
tail_number = models.ForeignKey(TailNumber, null=False, blank=False)
flight_number = models.CharField(max_length=30, null=False, blank=False)
flight_group_code = models.ForeignKey(FlightGroup, null=False, blank=False)
origin_port_code = models.ForeignKey(Port, null=False, related_name="Origin", blank=False)
destination_port_code = models.ForeignKey(Port, null=False, related_name="Destination", blank=False)
flight_departure_time = models.TimeField()
start_date = models.DateField()
end_date = models.DateField()
def __unicode__(self):
return u'%s' % self.flight_number
class Meta:
verbose_name_plural = "flights Schedule"
class PosFlightSchedule(models.Model):
tail_number = models.ForeignKey(TailNumber, null=False, blank=False)
pos_flight_number = models.ForeignKey(FlightSchedule, max_length=30, null=False, blank=False,
related_name='pos_flight_number')
pos_flight_departure_time = models.ForeignKey(FlightSchedule, max_length=30,
related_name='pos_flight_departure_time')
pos_route_id = models.ForeignKey(FlightScheduleDetail, null=False, blank=False, related_name='pos_route_id')
pos_flight_date = models.ForeignKey(FlightScheduleDetail, null=False, blank=False, related_name='pos_flight_date')
pax_count = models.IntegerField(null=True)
def __unicode__(self):
return u'%s' % self.pos_flight_number
class Meta:
verbose_name_plural = "Flights Schedule"
For the pos_flight_departure_time , I need the choices from flight_departure_time from the FlightSchedule class. But I get the flight_number values in the drop down. What do I have to change, to get the flight_departure_time values? The classes are from different apps in a single django project. So they have two admin files.
No you don't actually need that. You need only one foreign key in your second model to FlightScheduleDetail and you need just one foreign key to FlightSchedule
class PosFlightSchedule(models.Model):
tail_number = models.ForeignKey(TailNumber, null=False, blank=False)
flight = models.ForeignKey(FlightSchedule, null=False, blank=False,related_name='pos_flight_number')
related_name='pos_flight_departure_time')
pos_route_id = models.ForeignKey(FlightScheduleDetail, null=False, blank=False, related_name='pos_route_id')
pax_count = models.IntegerField(null=True)
def __unicode__(self):
return u'%s' % self.pos_flight_number
class Meta:
verbose_name_plural = "Flights Schedule"
Then all the fields declared in the first model automatically become available to PosFlightSchedule
So for example you can do
p = PosFlightSchedule.objects.all()[0]
print (p.flight.flight_number)
print (p.flight.pos_flight_departure_time)
etc.
This is the correct way to do it.
You may solve this by defining model form, and by not changing to models.py
class PosFlightScheduleForm(forms.ModelForm):
pos_flight_departure_time = forms.ChoiceField(label="Pos Department Time",
choices=[(i.pk, i.flight_departure_time) for i in FlightSchedule.objects.all()],
required=True)
def __init__(self, *args, **kwargs):
super(PosFlightScheduleForm, self).__init__(*args, **kwargs)
self.fields['pos_flight_departure_time'] = forms.ChoiceField(label="Pos Department Time",
choices=[(i.pk, i.flight_departure_time) for i in FlightSchedule.objects.all()],
required=False)
class Meta:
model = PosFlightSchedule
fields = (
"tail_number", 'pos_flight_departure_time',)
In view.py You may use this form
def add_view(self, request):
form = PosFlightScheduleForm(request.POST or None)
if form.is_valid():
form.save()
return redirect('/postflights')
context = {
'form': form,
}
return render(request, 'path/form.html', context)
I have a Django 'add business' view which adds a new business with an inline 'business_contact' form.
The form works fine, but I'm wondering how to write up the unit test - specifically, the 'postdata' to send to self.client.post(settings.BUSINESS_ADD_URL, postdata)
I've inspected the fields in my browser and tried adding post data with corresponding names, but I still get a 'ManagementForm data is missing or has been tampered with' error when run.
Anyone know of any resources for figuring out how to post inline data?
Relevant models, views & forms below if it helps. Lotsa thanks.

The problem is you have not included the management form in your data. You need to include form-TOTAL_FORMS (total number of forms in the formset, default is 2), form-INITIAL_FORMS (the initial number of forms in the formset, default is 0) and form-MAX_NUM_FORMS (the maximum number of forms in the formset, default is '').
See the Formset documentation for more information on the management form.
