hi
i wrote a function for producing tuples of all model names, which is this:
from django.contrib.contenttypes.models import ContentType
from django.db.models.loading import get_model
def get_all_models():
return tuple([(each.__module__+'.'+each.__name__,each.__name__) for
each in [each.model_class() for each in
ContentType.objects.filter(app_label__in=['products','productoptions','shoppingcart'])
if each is not None] if each is not None])
when i run this in my shell it gives this output:
(('shoppingcart.models.Cart', 'Cart'), ('shoppingcart.models.CartItem',
'CartItem'), ('shoppingcart.models.CartRule', 'CartRule'),
('products.models.CasesAccessory', 'CasesAccessory'),
('productoptions.models.Coating', 'Coating'),
('shoppingcart.models.ConditionSet', 'ConditionSet'),
('products.models.Eyeglass', 'Eyeglass'), ('products.models.GiftVoucher',
'GiftVoucher'), ('productoptions.models.Lens', 'Lens'),
('productoptions.models.Prescription', 'Prescription'),
('products.models.Readingglass', 'Readingglass'),
('products.models.Sunglass', 'Sunglass'), ('productoptions.models.Tint',
'Tint'), ('productoptions.models.Vision', 'Vision'))
while at choices my first option got lost and output is:
(('shoppingcart.models.CartItem', 'CartItem'),
('products.models.CasesAccessory', 'CasesAccessory'),
('productoptions.models.Coating', 'Coating'), ('products.models.Eyeglass',
'Eyeglass'), ('products.models.GiftVoucher', 'GiftVoucher'),
('productoptions.models.Lens', 'Lens'),
('productoptions.models.Prescription', 'Prescription'),
('products.models.Readingglass', 'Readingglass'),
('products.models.Sunglass', 'Sunglass'), ('productoptions.models.Tint',
'Tint'), ('productoptions.models.Vision', 'Vision'))
why did this happened and whats the fix ?
