I have a list of objects. Each object has a field called grade
whose value is between 0 and 5. Now I want to see the distribution of this field across my list of objects. Is there any way to find it?
I know I can iterate over the whole objects and find it out but I don't want to do that.
As near as I can tell, using a table Table
with a grade
column you need something like this:
counts = Table.objects.annotate(count=Count("grade", distinct=True)
This adds a count
attribute to each member of the counts
query set, which you can access just like a regular database column.
