What would you think about making the method name something a little
For something adding new SQL (especially new SQL that alters the
database), tests are essential.
This is also, I think, the first time, users can alter the database's
content from the collection class. Given the way we use JDBI in Jifty,
this would have the side-effect of walking around our access control.
This also doesn't quite have the effect I'd expect.
If I create a collection, check that it has the right things in it and
then call delete:
1) I'm not sure I get the right result with regard to paging
2) If someone else has added a matching row in the meantime,
I'm going to be a VERY sad user ;)
Would you be happy with a solution that called the records' delete
methods instead? That has the added benefit of catching model-specific
delete code too :)
