Setting initial values in Django Form

Question

I have a Django form:

class PlayerForm(forms.Form):
    OPTIONS = MyUser.objects.all()
    players = forms.ModelMultipleChoiceField(widget=forms.CheckboxSelectMultiple,
                                             queryset=OPTIONS)

I want the initial values of the players to be checked if MyUser.player = True. How do I set these initial values?

You need to set the initial attribute on the players field to be a list of the relevant MyUser ids. A quick way to do this is to use the initial keyword argument of ModelMultipleChoiceField:

players = forms.ModelMultipleChoiceField(widget=forms.CheckboxSelectMultiple,
                                         queryset=OPTIONS,
                                         initial=[u.pk for u in OPTIONS if u.player])
