Enabling features for specific users

[altaha]

The feature set for gutter is pretty suitable for rolling out a feature to groups of users, or of course as a global on/off feature toggle. But if you want to enable a feature for specific users, the only way I can see gutter supporting that is by adding a condition for each user you want the switch to be active for. I imagine this becomes very slow if you want it enabled for say a thousand users in beta testing.

Am I missing something here, or is this usecase not well suited to gutter?

Thanks!

The gutter API is pretty flexible for whatever you wanted to do - it's all just Python.

To match a known set of user IDs, you'd just need to make an operator that inherits from the Base operator. That operator, i.e. called ContainedIn, would just need to implement the applies_to method to check if the argument is contained within the collection ContainedIn would be constructed with.

class ContainedIn(Base):

    name = 'contained_in'
    group = 'comparable'
    preposition = 'contained in'
    arguments = ('value',)

    def applies_to(self, argument):
        return argument in self.value

    def __str__(self):
        return 'contained in "%s"' % self.value

The API would look something like:

users = {1,2,42,}
operator = 
condition = Condition(argument=UserArgument, attribute='id', operator=ContainedIn(users))

You can retrieve your users collection however you want - DB, Redis, hard coded, etc. Each option has tradeoffs though, so you should choose what is right for your use case.
