Hi,
I have a dictionary where the key is the primary key from one of my
database tables, and the values are the values that I want to update with.
For example, I may have the following dictionary:
new_values = {1:'a', 2:'b', 3:'c'}
And the following model:
class TestThing(models.Model):
new_value = models.IntegerField(default=0)
And I want to update the entry with primary key 1 with value 'a', etc.
Note that there are other fields in the table that need to be preserved, so I
can't just create a new table.
Obviously, I could loop through each entry and update each entry individually,
but this seems really inefficient, so I think there must be a better way to do
this.
Also, my table may have entries that aren't represented in my dictionary, so I
don't think I can do the following:
TestThing.objects.all().update(new_value=new_values[F(id)])
Thanks,
Don
