Hello there Galvin,
You can create properties on the users and filter the queryset conditioning to
the user. It depends on how many categories of user you have and how these
users are supposed to be filtered by those teams.
For example, if you have a spatial selection based on user location, you create
a property called ‘location_filter’ and set the separation rule on this
property, like:
@property
def location_filter(self):
location = self.location
filter_rule = 5miles
return [self.location - filter_rule, self.location +
filter_rule]
and in your form you set a init argument to query those filter rules, in the
fashion that you want:
def __init__(self, *args, **kwargs):
user = kwargs.pop(‘user’, None)
self.fields[‘club_id’].queryset =
Club.objects.filter(place__lte=user.location_filter[1],
place__gte=user.location_filter[0])
I have not tested this solution, but with some minor code changes it should
work like a charm in filtering the club queryset.

Subject: Trying to filter out choices in a form based on the logged in user.
Hi all,
If anyone could help or point me in the direction of some documentation for the
below problem I am having I would really appreciate it.
Just to explain quickly:
1. I have a model called "Team" which contains a foreign key to another
model called "Club"
2. The "Club" model contains a foreign key to the "User" model.
3. I have a form for the "Team" model which takes in "club_id", currently
it lists all the club_id for all users and I want to restrict this.
4. I am looking to find out how I can auto-populate this field "club_id"
based on the logged in user, which I will then hide in the form.
Below is my forms.py
class ClubInfoForm(forms.ModelForm):
club_address2 = forms.CharField(required=False)
club_address3 = forms.CharField(required=False)
class Meta():
model = ClubInfo
fields = ('club_name', 'club_logo', 'club_address1', 'club_address2',
'club_address3', 'club_town', 'club_county', 'club_country',)
def clean_club_name(self):
club_name = self.cleaned_data['club_name']
if ClubInfo.objects.filter(club_name=club_name).exists():
raise ValidationError(_("Club already exists"))
return club_name
class TeamForm(forms.ModelForm):
class Meta():
model = Team
fields = ('club_id', 'team_name', 'manager_name')
def __init__(self, *args, **kwargs):
super(TeamForm, self).__init__(*args, **kwargs)
models.py
class ClubInfo(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
club_name = models.CharField(max_length=50, default='', unique=True)
club_logo = models.ImageField(upload_to='profile_pics', blank=True)
club_address1 = models.CharField(max_length=30)
club_address2 = models.CharField(max_length=30, default='')
club_address3 = models.CharField(max_length=30, default='')
club_town = models.CharField(max_length=30)
club_county = models.CharField(max_length=30)
club_country = models.CharField(max_length=30)
created_date = models.DateTimeField(default=timezone.now)
def __str__(self):
return self.club_name
class Team(models.Model):
club_id = models.ForeignKey(ClubInfo, on_delete=models.CASCADE)
team_name = models.CharField(max_length=30)
manager_name = models.CharField(max_length=20)
def __str__(self):
return self.team_name
