Problem - Updating objects with a view that you've already got a reference to
While writing unittests for a django application, I would create an instance of a model in the
setUp(), then call some view in the test, using the django test client. I would then like to test the original object from the setUp.
This is easy enough, however I ran into a problem where it looked like the object wasn't being updated by my view function. It turns out it was because Django had loaded that object from the database at the start, and hadn't updated it after my view function.
Solution - Reload the object from the database
The solution is to reload the object from the database (to 'refresh' it). You can do it with this command:
x = X.objects.get(id=x.id)
X with the name of your model class, and
x with the variable you had assigned the object to
x should now be the most up to date version of that object and should have any attributes set
There is a long standing django feature request to add this reload method, however the django developers have decided that this work around is easy enough.
