Django Dynamic Forms ManyToManyField - django

Question

I have a problem that I want to make a football league page that can submit the starting XI list.
But I don't know how to build the Dynamic Form.
User (which is the team owner) can Login to choose the match to upload the starting XI.
Website will show up the player list of the Team and let the User select Max of 11 and submit.
The important thing is
How can I generate the form with the Players belongs to Team.
How to let the User upload Home / Away (The team belongs to User) starting XI only.
Model.py
class Schedule(models.Model):
schedule_name = models.CharField(max_length=7, choices=LEAGUE_CHOICES, default='nil')

How can I generate the form with the Players belongs to Team.
You first would need a form for players:
class PlayerForm(forms.ModelForm):
class Meta:
model = Player
fields = '__all__'
and then put this into practice: Django Formsets
How to let the User upload Home / Away (The team belongs to User) starting XI only.
You will need here a form too, this time for the Schedule model as well.
#rchurch4 said: They just want to know how to ensure that the User can only upload the roster for his team.
If that the case, you only have to be sure in your Team list view you only list teams belonging to the authenticated User.
