Allow me to clarify. :-) host.enableMaintenance(apiclient) is how I was invoking it. Just like a regular instance method.
For some reason, it wanted to invoke the class method when I did that and was complaining about the lack of a parameter. That being the case, I switched my code to the following (to make use of the class method): Host.enableMaintenance(apiclient, host.id) The weird part is that it seems like Python was trying to invoke the class method when I had syntax specifying I wanted to invoke the instance method. To circumvent the issue, I just switched my syntax to make use of the class method instead of the instance method. Seems like I shouldn't have had to do that, though. > On Apr 30, 2016, at 6:30 AM, Will Stevens <williamstev...@gmail.com> wrote: > > You are probably getting this error because you are trying to call: > Host.enableMaintenance(client) > > Check my examples above for how to call it. > > Sorry I am on my phone, so I am not very efficient with my phone and cant > civet you better details. :) >> On Apr 30, 2016 8:23 AM, "Will Stevens" <williamstev...@gmail.com> wrote: >> >> Here is a pretty good explanation. >> >> >> http://stackoverflow.com/questions/136097/what-is-the-difference-between-staticmethod-and-classmethod-in-python >> >> I am guessing that both exist because the function is called both with a >> host instance and with the class itself. >> >> Class instance example: `h.enableMaintenance(client)` >> >> Class example: `Host.enableMaintenance(client, 1)` >> >> In both cases the first parameter is implicitly `h` and `Host` >> respectively. >> >> I am not sure why we need both (because I am not familiar with how this >> code is called), but method overloading is definitely valid in python. >> >> On Apr 30, 2016 1:08 AM, "Tutkowski, Mike" <mike.tutkow...@netapp.com> >> wrote: >>> >>> Hi everyone, >>> >>> >>> I received an error when trying to invoke the instance version of >> enableMaintenance (below). >>> >>> >>> 'TypeError: enableMaintenance() takes exactly 3 arguments (2 given)\n'] >>> >>> >>> I looked at base.py and it has the following with regards to maintenance >> mode for hosts: >>> >>> >>> def enableMaintenance(self, apiclient): >>> >>> """enables maintenance mode Host""" >>> >>> >>> cmd = prepareHostForMaintenance.prepareHostForMaintenanceCmd() >>> >>> cmd.id = self.id >>> >>> return apiclient.prepareHostForMaintenance(cmd) >>> >>> >>> @classmethod >>> >>> def enableMaintenance(cls, apiclient, id): >>> >>> """enables maintenance mode Host""" >>> >>> >>> cmd = prepareHostForMaintenance.prepareHostForMaintenanceCmd() >>> >>> cmd.id = id >>> >>> return apiclient.prepareHostForMaintenance(cmd) >>> >>> >>> Now, I definitely have a lot more Java experience than Python, but - as >> far as I know - having two methods with the same name such as this (even if >> one is an instance method and the other is a class method) is not really >> "permitted" in Python. >>> >>> >>> I mean, technically it's permitted, but the second one will override the >> first one. >>> >>> >>> Can any of our Python people comment on this? >>> >>> >>> I was thinking I'd remove the class method (assuming my knowledge here >> regarding this topic is correct). >>> >>> >>> Thanks! >>> >>> Mike >>
