Hello,
I'm having an issue with my schema and the admin interface where I got
2 tables with a ManyToMany relationship: Employee and Team.
The problem is I'm able to add one Employee to the same Team twice.
Is there a way to prevent this from happening? Adding 'unique' to the
Employee FK makes it so Employees can only join one Team).
The code I'm using (irrelevant parts removed):
from django.db import models
from django.contrib.auth.models import User
class Employee(models.Model):
name = models.CharField(max_length=30, unique=True)
user = models.ForeignKey(User)
class Team(models.Model):
name = models.CharField(max_length=60)
members = models.ManyToManyField('Employee', blank=True,
through='TeamMember')
class TeamMember(models.Model):
employee = models.ForeignKey(Employee)
team = models.ForeignKey(Team)
is_leader = models.BooleanField('Is Leader?')
Thanks in advance.
