[10:44:18] <s1x> I am getting a class through a configuration key: key = importString('my.module:MyClass')
[10:44:27] <s1x> I want to binding.Make it
[10:44:33] <s1x> currently i'm doing:
[10:45:01] <s1x> MyClassFactory = binding.Obtain ("some.key")
[10:45:17] <s1x> MyClassFactory = binding.Obtain (PropertyName ("some.key"))
[10:45:47] <s1x> MyClass = binding.Make (lambda self: self.MyClassFactory (self))
[10:45:54] <s1x> is there a prettier way to do it?
[11:54:33] <s1x> i've seen something about [Component Factories] in the bulletins example. Does it solves the "problem" I'm having?
[12:29:44] ** pje has joined us
[12:30:21] <pje> Yes, it does.  If you specify a component factory for an interface, you can then use binding.Make(theInterface)
[12:31:30] <pje> So if it's some_mdoule.IFoo, you do:
[12:31:36] <pje> [Component Factories]
[12:31:57] <pje> some_module.IFoo = "other_module.ClassImplementingIFoo"
[12:32:31] <pje> And then 'myFoo = binding.Make(IFoo)' in the class will do the trick.
[12:35:19] <pje> It also works for non-interface component keys, but the trick there is that you have to define the key in a module so it can be imported.
[12:35:49] <pje> If you look at the bulletins example, it does this for BulletinDM, etc., using DMFor() config keys instead of interfaces.
[12:36:25] <pje> Also, for a given configuration key, if you want all components in the same service area to share a common instance, you can use binding.Obtain(IFoo) instead of binding.Make(IFoo)
[12:37:17] <pje> Any key with a component factory will have a default instance tied to the ServiceArea component (usually the config root), so if you Obtain it, it will be shared with others Obtaining it.
[12:37:28] <pje> But you can still also have components that Make() their own.

[12:58:25] <s1x> how can I define a key in a module?
[15:12:34] ** pje has joined us
[15:12:45] <pje> By saying someKey = expression
[15:12:56] <pje> e.g. someKey = storage.DMFor(SomeModelClass)
[15:13:06] <pje> someKey = PropertyName('some.property')
[15:13:07] <pje> etc.
[15:23:05] <s1x> i see
[15:23:17] <s1x> lemme try it :)
[15:34:31] <s1x> nice, worked like a charm :)
[15:49:24] <[apoirier]> hi pje
[15:49:58] <[apoirier]> playing with PWT, I'am surprised how it seems to be tied to the web publication system
