Hello,
I have created my own ManyToMany table, but am getting an error when I
attempt to get a related item from one of my Models. Any insight would be
greatly appreciated. I am on Django 1.3.1. *models/restuarant_hood_map.py*
<import restaurant and hood>
class RestaurantHoodMap(models.Model):
restaurant = models.ForeignKey(Restaurant)
hood = models.ForeignKey(Hood)
class Meta:
db_table="restaurant_hood_map"
app_label="delivery"
Error:
AttributeError at <URL>
'str' object has no attribute '_default_manager'
*models/hood.py*
class Hood(models.Model):
name = models.CharField(unique=True)
restaurants=models.ManyToManyField("restaurant.Restaurant",
through="restaurant_hood_map.RestaurantHoodMap")
class Meta:
db_table = "hoods"
app_label="delivery"
*models/restaurant.py*
class Restaurant(models.model):
name=models.ForeignKey(CompanyName)
is_active=models.BooleanField(default=True)
hoods=models.ManyToManyField("hood.Hood",
through="restaurant_hood_map.RestaurantHoodMap")
class Meta:
db_table="restaurants"
app_label="delivery"
Now, I know what the problem is.....when I attempt to get the related
restaurants off of Hood, I am getting this error. That's because it's
treating the "restaurant.Restaurant" as a string value. However, I thought
it was accepted to use string values in order to avoid circular
dependencies? At least thats what I thought from the docs:
https://docs.djangoproject.com/en/dev/ref/models/fields/#foreignkey
However, that doesn't seem to work when you get a Hood object and do
hood.restaurants....it barfs.
Thanks for the help!
