Nested flask.cli commands

[mpounsett]

I have reason to build a command tree in an app I'm working on that is deeper than just cli.AppGroup:command. From reading the click docs it seems like I should be able to insert a group in between, but it's not working as I expect .. and I wonder if someone can suggest what I'm doing wrong.

The general structure of my code looks something like this:

ag = flask.cli.AppGroup('foo')

@ag.group('bar')
def bar():
   pass

@bar.command('baz')
@bar.option('-x', '--xcellent')
@bar.argument('party')
def bar_baz(xcellent, party):
   pass

However, I'm getting an exception indicating that groups do not have an option parameter. Presumably the party argument would produce a similar error if it wasn't occluded by the option.

AttributeError: 'AppGroup' object has no attribute 'option'

I also tried doing @ag.command('bar') to more literally nest command objects, but that also failed:

AttributeError: 'Command' object has no attribute 'command'

Is what I'm trying to do here actually permitted, and I'm just going about it wrong? Or do I need to rethink my command structure?

Thanks!

I'm embarassed that I didn't notice this earlier, but the option and argument decorators above should be @click.option and @click.argument, not @bar.... Leaving this here in case anyone else makes the same mistake, so this can be found.
