Re: django queryset based on when data created

You can use ordering by primary key (id by default) because it
increments by every insert.
So newly created rows in db will have greater  id than others.
In most cases it can be enough.

The order results are returned in SQL when you don't supply explicit
ordering is completely undefined. It can even change without the data
changing (if the database tables are vacuumed to better utilise space,
for example).

Unless you specify an ordering, there are no guarantees in this area.

django queryset based on when data created

2009-08-05 Thread Joru

Everytime I edit some data, the data order in queryset changed into
the newest edited
Is it posible to get queryset that ordered based when the data created
without having to add creation date for sorting purpose
