Bi-Directional ManyToMany

[[EMAIL PROTECTED]]

Hi

I've just defined a manytomany relationship in the following way

class ItemType(meta.Model):
    name = meta.CharField(maxlength=100)
    descritpion = meta.CharField(maxlength=250)

class PropertyType(meta.Model):
    name = meta.CharField(maxlength=100)
    itemtypes = meta.ManyToManyField(ItemType)

Excellent. When I make a new property type in the admin screens I get a
mutiselect window for item types.

What I want to be able to do however is have this work back the other
way too so that whe I create a new item i can specify what property
types apply.

Any ideas on whether this is at all possible? Or how I might go about
achieving it

Maybe this kind of thinking is breaking thew rules but it does seem
logical that themany-to-many relationship be bi-directional in this way

Thanks
Charlie
