[Answer]-Forms.CharField chokes on positional argument from in Django 1.6

Every field type is different. For a CharField (and also EmailField since it inherits from CharField), the first parameter is max_length.

I don’t know why you say that was valid before Django 1.5. Looking back at the code before 1.5, that should have been invalid then too.

Maybe you are thinking of a model field? For model fields, most of the time, the first parameter is the verbose_name, in which case, f = models.CharField('f') would make sense.
