[Grok-dev] bypass UI adding application to grok AND multiple applications under /src howto?

Mon Jan 16 06:56:53 UTC 2012

Hi Matt,

ok do you have a configure.zcml in your new paster based package? In 
every case you need it with the
following content:

<configure xmlns="http://namespaces.zope.org/zope"
            xmlns:grok="http://namespaces.zope.org/grok">
<include package="grok" />
<grok:grok package="." />
</configure>

Be sure that this configure.zcml is picked up on startup.

If you now have for example in this package a app.py with the following 
content:

class MyNewApp(grok.Application):
     pass

You should see this new grok application  MyNewApp in the grok-admin 
interface.

If you have further questions please ask....

HTH
Christian
