Hello,
I'm clearly missing something obvious with a ManyToManyField. I just want
to return a result list for the related table in a View.
So here is my Model:
class *Supply*(models.Model):
name = models.CharField(max_length=200)
...
class *Tool*(models.Model):
...
supplies = models.ManyToManyField(Supply, related_name=*'supplies'*,
blank=True)
I want to get a list of Tools for each Supply.
Here is my View code:
def *supplies*(request, page=*'chemicals'*):
renderdict = build_renderdict(request)
....
items = Supply.objects.filter(type__exact = type).order_by(*'name'*)
if len(items)!=0:
itemlist=[]
for item in items:
#sortedtools = item.tool_set.order_by('shortnamename')
print item.name
sortedtools = item.tool_set.all() # <------- ERROR HERE
itemlist.append({*'id'*:item.id,*'name'*:item.name, *
'minimum'*:item.minimum, *'current'*:item.current, *'reorder'*:(item.current
< item.minimum),
*'minimum_bmf'*:item.minimum_bmf,*'current_bmf'*:item.current_bmf,
*'reorder_bmf'*:(item.current_bmf < item.minimum_bmf), *'status'*:
item.status,
*'tools'*:sortedtools})
...
Here is the runtime error:
'Supply' object has no attribute 'tool_set'

What am I doing wrong?
TIA,
