Hello,
I am trying to create a form with fields based on types of an object
property. Basically, I am setting up a system which has hardware
'demos' which are categorized by industry. I want to create a form
which has a Checkbox Select Multiple for each industry, with the
choices being the demos for that industry. Currently, my (un-working)
form code looks like:
class select_demo_apps_frm(forms.Form):
# List apps from each industry with selection boxes for each app.
def __init__(self, *args, **kwargs):
super(select_demo_apps_frm, self).__init__(*args, **kwargs)
inds = industries() # returns all industry objects
for ind in inds:
fieldname = '%s' % ind.name
self.fields[fieldname] = forms.CheckboxSelectMultiple()
self.fields[fieldname].choices = [(d.id, marksafe('<b>%s</
b> - %s') % (d.name, d.desc)) for d in demo.objects.filter(industry =
ind)]
Unfortunately, I'm getting an error from this code:
Error when calling the metaclass bases
Cannot create a consistent method resolution
order (MRO) for bases Form, select_demo_apps_frm
It could be possible to set a static field for each industry, however
in the interest of long term maintainability I'd rather do it
dynamically in case new industries get added after I leave this job.
Just wondering if anyone can help with creating this form in such a
way that it actually works ;)
Thanks much!
Fernando Sanchez
