I am having trouble saving entities to my models that have ManyToMany relationships. I have a Student object that inherits from a Person:
class Person(models.Model): first_name = models.CharField(max_length=30) middle_name = models.CharField(max_length=30, blank=True) last_name = models.CharField(max_length=30) ... class Student(Person): parents = models.ManyToManyField('parents.Parent', blank=True, null=True) ... class Parent(Person): occupation = models.CharField(max_length=128, blank=True) In my view, I create a new Student: newStudent = Student(first_name='Donald', middle_name='R', last_name='Duck') newStudent.save() I also create a Parent and add the new parent to the list of parents for the student: newParent = Parent(first_name='Ronald', middle_name='T', last_name='Duck') newParent.save() newStudent.parents.add(newParent) However, when I call save_m2m(), it throws an error: newStudent.save_m2m() Perhaps I do not need to call save_m2m(). Does the relationship get saved to the database when I call the add() method? LJ -- You received this message because you are subscribed to the Google Groups "Django users" group.
