maybe I not explain correctly. For any modelForm the forms for a field
"ManytoMany" are "select multiple". If I want to change this I must

Hello list, I have a question. How can i define a custom
decimal_separator and a custom thousand_separator independently of the
locale?. I don't want redefine this values to every "locale". To my
problem, in every the template must to display the same thousand
separator and the decimal separator.
Hello list, I want to do something like my_field = 1000(this value can

Yes, you have reason. I prefer use something like an "exclude" or

.default = MyModel.objects.get(field=True)

and the form comeback, but with the values edited for the user and the
error messages. Can
