Re: retrieve row with maximum field value django

Thank you. This will do for my needs for now.  Picking the first max value that comes at the top is fine for me.

Use a combination of order_by('-age') and first() on your query set.

MyModel.objects.order_by('-age').first()

Obviously that only pulls the "first" object even if multiple objects have that same age, so you may need additional filter() and sorting criteria.

Say I have a model

class MyModel(models.Model)

    name = models.CharField(max_length=20)

    age = models.IntergerField()

How can I find the maximum based on the 'Age' field number and retrieve that whole object? I understand aggregates allows me to find and retrieve the maximum number when given a field to run on, but I only get the maximum number ONLY and not the other items in the row.

Does django have something that allows to find the maximum (or minimum) value of a database field, then retrieve whole row in the query?
