I have created a library for interacting with Bugzilla using the native REST API. Bugsy allows you to get bugs from Bugzilla, change what you need to and then post it back to Bugzilla. I have created documentation to get you started.

For example to get a bug you would do

import bugsy
bugzilla = bugsy.Bugsy()
bug = bugzilla.get(123456)

and then to put it back, or if there is no bug ID (like if you were creating it) then you would do

import bugsy
bug = bugsy.Bug()
bug.summary = "I really realy love cheese"
bug.add_comment("and I really want sausages with it!")
bugzilla = bugsy.Bugsy("username", "password")
bugzilla.put(bug)
bug.id #returns the bug id from Bugzilla

Searching Bugzilla is not currently supported but will definitely be there for the next version.
