11,332 PointsSerializer Custom Validator
In this challenge I need to write a custom validator for the PlayerSerializer, checking that players with an age
of less than 13 have parental_approval
. If they don't, I should raise a ValidationError to that effect.
When I run the attached code I receive this message: A young player was accepted as valid without parental approval!; A young player was reject even with approval!
Thanks for the help.
