graphql queries fail: "unhashable type: 'MSFList'"

[sanderboer]

I have made a model that uses a MultiSelectField. When I create a schema.py to query all entries of that model, it fails with the error: "unhashable type: 'MSFList'"

Is there a way to remedy this ?

thank you.

NB: Right now I copy the multiselectfield into a _str duplicate using the "save" method and I ignore the ages_allowed field in Graphql and read ages_allowed_str instead.

`
class Question(models.Model):
title = models.CharField(max_length=256)
ages_allowed = MultiSelectField(
choices=AGES,
null=False,
default=0,
max_length=get_max_length(AGES, None),
)
ages_allowed_str = models.CharField(max_length=256, blank=True)
info = models.TextField()
image = models.ImageField(upload_to=photo_path, blank=True)
published_at = models.DateTimeField(default=timezone.now)
author = models.ForeignKey(User, on_delete=models.CASCADE)
type = models.CharField(
max_length=64,
choices=ANSWERTYPE,
default="boolean",
)

    def save(self, *args, **kwargs):
            self.ages_allowed_str = ",".join(self.ages_allowed)
            super().save(*args, **kwargs)
        
    def __str__(self):
            return self.title
    
    def __unicode__(self):
            return self.__str__()

Can you please recheck with #135 ?

Not sure but this might fix your issue. If not, it'll be probably way easier to fix than before.
