How to use 'createObject'?

[Julian Sanchez]

After reading how to use the zca page I've managed to register a few utilities and adapters through

request.registry.registerUtility(...)

and

request.registry.getUtility(...)

How can you hook up the zope.component.createObject method?  I did my

request.registry.registrerUtility(foo_factory, IFactory, 'Foo')

but of course creatObject by itself will go against the global repository (and of course I get the dreaded 'could not adapt' error)

I tried the trick:

mycontext = zope.configuration.config.ConfigurationMachine()
mycontext.registry = request.registry

..and then

myfoo = createObject('Foo', context=mycontext)

But that also returns 'could not adapt'

Is my only option to do a

request.registry.getUtility(IFactory, 'Foo')()

instead of createObject?

Thanks,

Julian

I know almost nothing about what you just asked but I will point you to https://docs.pylonsproject.org/projects/pyramid/en/1.9-branch/narr/zca.html#using-the-zca-global-api-in-a-pyramid-application as well as the `config.hook_zca` method.

Thanks Michael.  That's the page that I had read.  Off the 3 options the one with the least possible side effects appears to be the one where you simply use the registry that pyramid generates and includes it to the request, which is what I'm pursuing at the moment.  

Does anybody know if there would be any side-effects if I had a config.hook_zca() statement in a 'includeme(config)' method if my pyramid app were to be used by another pyramid app?
