AutoImport

This is a hack for Zope products: import anything in Products/PRODUCT/import/ into /Control_Panel/Products/PRODUCT/ at startup time (if it's not already there). ZWiki used this at one point to install wiki templates from zexps.

 import os
 from Globals import package_home
 from OFS.ObjectManager import customImporters

 def autoImport(context):
    """Import any files in our import directory
       into /Control_Panel/Products/PRODUCT.
       Called at product startup and refresh.
    """
    importdir = package_home(globals()) + os.sep + 'import'
    if 0: #XXX not exists(importdir)
        return

    # sneaky, or dumb, way to get to the zodb
    obj = context.getProductHelp()
    productfolder = obj.getPhysicalRoot().Control_Panel.Products['ZWiki']
                                        #XXX find product name dynamically

    # based on manage_importObject
    # locate a valid connection
    connection=obj._p_jar
    while connection is None:
        obj=obj.aq_parent
        connection=obj._p_jar

    # try to import any and all files found
    # will fail if the object is already in the ZODB
    files = os.listdir(importdir)  
    for filename in files:
        filepath = importdir + os.sep + filename
        # how do we get these to show in undo ?
        #get_transaction().begin()
        try:
            ob=connection.importFile(filepath, customImporters=customImporters)
            # getId() fails on 'old' exported objects
            id=ob.id
            if hasattr(id, 'im_func'): id=id()
            productfolder._setObject(id, ob, set_owner=0)
            # try to make ownership implicit if possible
            ob=productfolder._getOb(id)
            ob.manage_changeOwnershipType(explicit=0)
            #get_transaction().commit()
            #XXX log it

        except:
            #get_transaction().abort()
            #XXX log it
            pass
