Hi!
A few days ago I've post a question about changing the unicode on a form
This was the answer:
one way is to override __init__. Here is a sample:
class Accountaddform(ModelForm):
def __init__(self,head,*args,**kwargs):
super (Accountaddform,self).__init__(*args,**kwargs)
self.head = head
self.fields['head'].queryset=Account.objects.filter(pk=self.head)
class Meta:
model = Account
(thanks Kenneth Gonsalves, it works as I wanted!)
Now I want to change the queryset.
I'm using the contib.auth.
I have a model wich I named Teacher and another wich I named Pupil.
After a user sign in the system, the admin classifies him as a theacher or a
pupil.
In self.fields['head'].queryset=Account.objects.filter(pk=self.head) I want to
change the queryset to only appears the pupils, it should return all the
records wich have an id in both models User and Pupil.
Now I have this
class Pupil(models.Model):
user = models.ForeignKey(User)
nr = models.IntegerField(blank=True,)
gender = models.CharField(max_length=1, blank=True,
choices=gender_choices)
...
class Teacher(models.Model):
user = models.ForeignKey(User)
schools = models.ManyToManyField(School, null=True, blank=True)
...
class Couple(models.Model):
man = models.ForeignKey(Aluno, related_name='man',)
woman = models.ForeignKey(Aluno, related_name='woman',)
...
class CoupleForm(ModelForm):
class Meta:
model = Couple
def __init__(self, *args, **kwargs):
super(CoupleForm, self).__init__(*args, **kwargs)
self.fields['man'].queryset=Pupil.objects.filter(gender='M')
self.fields['woman'].queryset=Pupil.objects.filter(gender='F')
It returns only the man and woman for each combo box. Now, also, I only want
the User wich aren't Teacher. How can I do this? I've tried with Manager.raw()
but it doesn't work or I don't know how to use it
Thanks
