setting up local utilities from outside grok

[Jasper Spaans-4]

Hi list,

I've got a small issue with setting up local utilities on a
grok.Application; I have something like the following:

class MyWonderfulApp(grok.Application):
    grok.local_utility(PluggableAuthentication, provides=IAuthentication,
                       setup=setup_authentication)

This works fine if I instantiate my application through the webinterface.
However, I'd like to be able to instantiate my application using some code
(which doesn't know a lot about grok), where I do something like:


grok.grok('my.app')
root = get_apps_root()  # this sets up the ZODB connection and returns the
                        # root object

if 'test' not in root:
    root['test'] = app = MyWonderfulApp(...)
    ...
    transaction.commit()

The application is available, I can access views, but no sitemanager or
localutil is registered, and my authentication thing is not set up.

Is there an easy way to get this to work?

Cheers,

Hi Jasper,

maybe you can look on zope.app.generation. I am not 100 % sure
if your usecase is doable with that package.

I try to give you a little code snippet which maybe works...

1. Add a directory called 'generations' in your package.
2. put this snippet into the generations/__init__.py:

from zope.app.generations.generations import SchemaManager

UVCSchemaManager = SchemaManager(
     minimum_generation = 1,
     generation = 2,
     package_name = __name__
)

3. Add an generations/install.py file with this content:
    (Note this file gets called exactly 1 times on startup of zope)

import zope.app.generations.utility

def evolve(context):
     print "Install Generation"
     root = zope.app.generations.utility.getRootFolder(context)
     #do your stuff here....

Hope this helps.
Please let me know if it works for you.
(Because i have the same problem but no time to tackle it...)

Take a look at site.txt in the zope.app.component for documentation on
sites. When instantiating a Grok app outside Grok, I think you need to
explicity set the site with zope.app.component.hooks.setSite():

  import zope.app.component.hooks
  root['test'] = app = MyWonderfulApp(...)
  zope.app.component.hooks.setSite(root['test'])

Then your local components should work as-expected (hopefully ... the
sites stuff is not my area of expertise)
