Thanks Rajesh - this works perfectly!
I now have another question...
What do I now do about manytomany fields for example look at the
contributor field in the example below - I want the current
contributors to be selected in the change form (these can obviously be
more than one)
models.py:
class SmallDesignSet(models.Model):
title=models.CharField(max_length=100)
priority=models.ForeignKey('Priority')
status=models.ForeignKey(Status, default=2)
concept=models.DateField()
contributor=models.ManyToManyField(Designer)
class Priority(models.Model):
priority=models.CharField(max_length=20)
class Designer(models.Model):
first_name = models.CharField(max_length=100)
last_name=models.CharField(max_length=100)
email=models.EmailField(unique=True)
def __str__(self):
return '%s %s' % (self.first_name, self.last_name)
form.py:
class SmallDesignSetSaveForm(forms.Form):
priority = forms.ModelChoiceField(
label='Priority',
queryset=Priority.objects.all()
)
status = forms.ModelChoiceField(
label='Status',
queryset=Status.objects.all()
)
title = forms.CharField(
label='Title',
widget=forms.TextInput(attrs={'size':64})
)
concept = forms.DateField(
label='Concept',
widget=forms.TextInput(attrs={'size':10})
)
contributor = forms.ModelMultipleChoiceField(
label='Contributor',
queryset=Designer.objects.all()
)
views.py:
def smalldesignset_save_page(request):
...
elif request.GET.has_key('id'):
id = request.GET['id']
designset = SmallDesignSet.objects.get(pk=id)
priority = designset.priority
status = designset.status
title = designset.title
concept = designset.concept
contributor = designset.contributor
form = SmallDesignSetSaveForm(initial={
'priority': priority.pk,
'status': status.pk,
'title': title,
'concept': concept,
'contributor': contributor,
})
Many thanks,
Martin
