The functional tests have warned us of a regression in our application: because we’re
now creating a new list for every single POST submission, we have broken the ability
to add multiple items to a list. This is exactly what we have functional tests for!
And it correlates nicely with the last item on our to-do list:
•
Get FTs to clean up after themselves
•
Adjust model so that items are associated
with different lists
•
Add unique URLs for each list
•
Add a URL for creating a new list via POST
•
Add URLs for adding a new item to an
existing list via POST
One More View to Handle Adding Items to an Existing List
We need a URL and view to handle adding a new item to an existing list (
/lists/<list_id>/
add_item
). We’re getting pretty good at these now, so let’s knock one together quickly:
lists/tests.py.
