Re: How to populate a form field with a Select widget
Finally got it working - and I'm sure there is a much clear way of
doing it...
used_fuels= Car.objects.all().values('fuel_type').distinct()
fuel_choices=[('Any','Any Fuel')]
for f in used_fuels:
for key,value in f.items():
fuel_choices.append((value,value))
fuels = forms.ChoiceField(choices=fuel_choices)

Re: How to populate a form field with a Select widget
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.

Re: How to populate a form field with a Select widget
A formatting error occurred while I did my previous post.
Please make sure that you notice the parentheses at the last line of
the code snippet, which were actually meant to be at the end of the
previous line.

Re: How to populate a form field with a Select widget
You can do it as follows:
class MyForm:
CHOICES = ( ('P', 'Pending'), ('A', 'Active'), ('D', 'Done'))
status = forms.ChoiceField(choices=CHOICES,widget=forms.Select
())

How to populate a form field with a Select widget
I would like to populate a form field which uses a Select widget with
choices in views.py.
I understand I can pass the initial arg to the form but I couldn't find the
correct value to pass.
The choices is a list of tuple
CHOICES = ( ('P', 'Pending'), ('A', 'Active'), ('D', 'Done'))
Any hints?
