Following on from this example, I am trying to use values from a table
to populate a choicefield (and been at it for 2 days trying every
method I can find in google....)
Clearly from the output below, I am creating the wrong kind of data
type, but don't know how to change it:
THIS VERSION WORKS:
>>> CHOICES = ( ('P', 'Pending'), ('A', 'Active'), ('D', 'Done'))
>>> print CHOICES
(('P', 'Pending'), ('A', 'Active'), ('D', 'Done'))
>>> fuel_type = forms.ChoiceField(choices=CHOICES,widget=forms.Select ())
>>> print fuel_type.choices
[('P', 'Pending'), ('A', 'Active'), ('D', 'Done')]
>>>
THIS VERSION DOES NOT:
(fails with Caught an exception while rendering: need more than 1
value to unpack)
>>> CHOICES = Car.objects.all().values('fuel_type','fuel_type').distinct()
>>> print CHOICES
[{'fuel_type': u'Petrol'}, {'fuel_type': u'Diesel'}]
>>> fuel_type = forms.ChoiceField(choices=CHOICES,widget=forms.Select ())
>>> print fuel_type.choices
[{'fuel_type': u'Petrol'}, {'fuel_type': u'Diesel'}]
Any help as to the best way of doing this would be great - I also need
to add 'Any Fuel' as the first option as this is for a search form.
