Thanks Jeremy,
Yes. Here's the Student model:
class Student(models.Model):
GRADE_CHOICES = (
('K', 'Kinder'),
('1', '!st Grade'),
('2', '2nd Grade'),
('3', '3rd Grade'),
('4', '4th Grade'),
)
parents = models.ManyToManyField(User, filter_interface=True)
teacher = models.ForeignKey(Teacher)
first_name = models.CharField(max_length=32, core=True)
last_name = models.CharField(max_length=32, core=True)
age = models.IntegerField(blank=True, null=True)
class_year = models.IntegerField()
grade = models.CharField(max_length=1, choices=GRADE_CHOICES)
sibling = models.BooleanField()
default_mon_scene = models.ForeignKey(Scenario,
verbose_name="Monday", related_name='mon_scene')
default_tue_scene = models.ForeignKey(Scenario,
verbose_name="Tuesday", related_name='tue_scene')
default_wed_scene = models.ForeignKey(Scenario,
verbose_name="Wednesday", related_name='wed_scene')
default_thu_scene = models.ForeignKey(Scenario,
verbose_name="Thursday", related_name='thu_scene')
default_fri_scene = models.ForeignKey(Scenario,
verbose_name="Friday", related_name='fri_scene')
As you can see, students have a m2m relationship with parents. When a
user/parent logs in, they are redirected to a view which loads their
students. If there are more than one, they are offered a choice of
which one to edit. If only one, they go straight to that student's
page.
This is all fine, except that the authenticated user is free to travel
to any student's page simply by altering the URL student.id parameter.
In the student view, I want to check the student.id against the
students associated with the currently logged in user. If they don't
jibe, I will redirect back to the select_student view.
I hope that makes my situation clearer.
I was thinking I would iterate through the parent/user object looking
for a matching student id, but not sure how.
