Hi Malcolm - Sorry, another formset question. Maybe you'll know the
answer offhand, have been trying to figure this out for awhile now.
I'm trying to set the initial value for a form field inside the
constructor for the form. The high level goal is to send out the
'tile' field as a hidden input so that I can get it back in the POST
so that I can figure out wich 'tile' each form in the forset
corresonds to.
For example, I'm trying to do this in my form constructor
(specifically see the ==> line)
class TaskTileDetailForm(forms.ModelForm):
class Meta:
model=TaskTileDetail
exclude=('task')
def __init__(self, tile, *args, **kwargs):
super(TaskTileDetailForm, self).__init__(*args, **kwargs)
self.fields['tile'].widget = forms.HiddenInput()
==> self.fields['tile'].initial = tile.id
If I do this, then later when processing my POST data there is no
'tile' key in cleaned_data. IE, I get a KeyError when I do this:
if taskTileDetailForm.cleaned_data["tile"] in taskTiles:
If I intiaizize it with the initial arg when creating the formset, the
cleaned_data["tile"] key is set just fine, ie when I use initial as
shown at the ==> below:
def makeTaskTileDetailFormSetForCreate(tileList, data=None):
TaskTileDetailFormSet = formset_factory
(form=TaskTileDetailForm, formset=CustomBaseFormSe)
initial = []
for tile in tileList:
initial.append({'tile': tile.id})
==> taskTileDetailFormSet = TaskTileDetailFormSet(data,
tiles=tileList, initial=initial)
return taskTileDetailFormSet
Is there something I am doing wrong when trying to initialize it as
shown in the first snippet with:
==> self.fields['tile'].initial = tile.id
that is causing cleaned_data to not get set when
taskTileDetailFormSet.is_valid() is called?
Sorry, I know this is hazy - have just been pulling my hair out
forever now ...
