I have a few models that looks like this:
-----
class Route(models.Model):
points = models.ManyToManyField(Base, through="RouteBase")
often = models.IntegerField(choices=ROUTE_OFTEN, default=0)
class RouteBase(models.Model):
point = models.ForeignKey("Base")
route = models.ForeignKey(Route)
sequence = models.IntegerField()
class Base(models.Model):
identifier = models.CharField(max_length=8)
lat = models.DecimalField(max_digits=10, decimal_places=7)
long = models.DecimalField(max_digits=10, decimal_places=7)
comment= models.ManyToManyField(Comment, blank=True)
-----
Everything is fine and dandy, except for when I want to use the admin
interface to create a new route. All I see is a dropdown for the
"often" field. I have to go to the RouteBase section of the admin to
add the rest. Normally if there is a ManyToMany field, in the admin
interface there will be a little green plus sign that you can use to
create a new object to attach. If the "through" option is used, it
doesn't show up. Why? Is there a way to change this behavior? Is this
a bug or is there a reason for this?
