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

[Christian Schmidt]

regarding the generations issue, Christian brought me to the right way, 
so I was able so solve this too.

I made the following:

cd src/example/
mkdir generations
cd generations
touch __init__.py
touch util.py
touch install.py
touch evolve1.py

util.py:

import grok
from zope.generations.generations import SchemaManager
from zope.generations.interfaces import ISchemaManager


schemaManager = SchemaManager(
         minimum_generation=1,
         generation=1,
         package_name='example.generations'
         )


grok.global_utility(
         schemaManager,
         provides=ISchemaManager,
         name="example",
         direct=True
         )

install.py:

from example.app import Example
from zope.generations.utility import getRootFolder

def evolve(context):
         root = getRootFolder(context)
         root['example'] = Example()      #<- root['example']  is the 
name of your Application displayed by the UI
         print "CREATED App example"


evolve1.py:

from zope.generations.utility import getRootFolder

def evolve(context):
         root = getRootFolder(context)
         app = root['example']

cd ../

configure.zcml (example/src/example/configure.zcml):

<include package="zope.generations" file="subscriber.zcml"/> #<-  NOT 
file="subscriptions.zcml"

cd ../../
add zope.generations to global setup.py:

example/setup.py:
  install_requires= [ ...
                         'zope.generations',

rerun buildout.

running your application will display "CREATED App example" on startup. 
UI displays example as installed application.

Cheers Christian Schmidt
