Hi everyone - wondering if someone could point me in the right
direction with this one?
I am trying to populate fields in a form with data from the database
(i.e., a change form rather than an add new form). It works fine for
populating Char/Date Fields but when I do the same for ForeignKey or
m2m fields I loose the information about the items that have been
selected. I.e., for a foreign key I get the dropdown for the foreign
key list but no single item is highlighted as selected.
Below is an example:
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()
class Priority(models.Model):
priority=models.CharField(max_length=20)
...
forms.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})
)
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
form = SmallDesignSetSaveForm(initial={
'priority': priority,
'status': status,
'title': title,
'concept': concept,
})
