Problem:
A school class was named like vim-e2-blö
During import this is “ö” is replaced with “-” and looks like ‘VIM-E2-BL-’ in the end. But the import does not allow a “-” as an endcharacter of a classname.
The character replacement logic does not sufficiently validate the resulting class name. Replacing “Ö” with “-” can lead to invalid class names, for example when the character occurs at the end of the name.
raise ValidationError(self.errors.copy())ucsschool.lib.models.attributes.ValidationError: {‘name’: [‘Value must not contain anything other than digits, letters, dots or spaces, must be at least 2 characters long, and start and end with a digit or letter!’]}
Solution:
Name your class properly.
