New description:
There's some weird internal Django bug with views that use
"transaction.atomic()" if you ping that view with multiple TestCase a
weird bug will happen where there's a DB check at the end of tests after
the DB has been torn down. I made 2 StackOverflow posts regarding this
issue and found the fix as well. Hopefully there'll be an internal fix.
Because Django tests the db transaction processing mechanism, the real
test part is finish and success, and then it will rollback the data（data
flush),so some db level check is no use and misleading.
so we need modify the foreign key check defer to make it get right result.
