I have these two rather simple models that looks something like this:
class MyModel(models.Model):
myName=models.CharField(max_length=60)
class MyOtherModel(models.Model):
myString=models.CharField(max_length=60)
myModel=models.ForeignKey(MyModel)
I will eventually have quite a number of MyOtherModelinstances. I have
made a form where the users enters a string and a myModel instance,
and it gets saved to the database. I need a query to get all the
MyModel instances that has a certain stringvalue in myOtherModel, but
only if it is the last entered one. My current solution is this:
for i in mymodel.myothermodel_set.all():
myOtherModel=MyOtherModel.objects.filter(myModel=i).order_by('-id')[:
1].get()
if myOtherModel.myString==certainStringValue:
objectsToRetur.append(i)
This works, but I think it's not a very good. Is there maybe a better
solution?
Thanks!
Odd-R.
