05:31 < mmarshall> Try that.
05:31 < maurycypw> ugh?
05:31 < maurycypw> ugly, but works.
05:31 < mmarshall> hehe
05:31 < maurycypw> why it works?
05:31 -!- slightlyoff [~alex@12.180.45.190] has joined #django
05:32 < mmarshall> Django must need a function name.
05:32 < mmarshall> All you were giving it was a module name.
05:32 < maurycypw> eh. it should be fixed
05:32 < maurycypw> next ticket, please!
05:32 < mmarshall> I guess that the error was so unhelpful because it only
                   looked for attributes that were functions.
05:33 < mmarshall> In this case, you had an attribute named 'login', but it was
                   another module.
05:33 < mmarshall> And yes, it should be fixed :D
