Hello I have model like



class mymodel(models.Model):

    a = models.CharField(blank=True, null=True, max_length=255)

    b = models.CharField(blank=True, null=True, max_length=255)

    c = models.CharField(blank=False, null=False, max_length=255)


Since I'm using the django admin as a back-end controller of the data stored in my model I want to make either one of them to not be null



for example the user must either fill a or either fill b or both to be filled, but if both are empty must throw an error

          You can add custom validation like this



          class mymodel(models.Model):
          
    a = models.CharField(blank=True, null=True, max_length=255)
          
    b = models.CharField(blank=True, null=True, max_length=255)
          
    c = models.CharField(blank=False, null=False, max_length=255)
          

          
    def clean(self):
          
        if not (self.a and self.b):
          
            raise ValidationError(....)

                    Run scheduled task as local user group (not BUILTIN)

                    0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
