Introduction

The package is monkey patch zexp import without triggering the object events.

To Solve

During import zexp file, we faced a lots of errors related to event notify from object. One of the examples as below:

2014-04-02T08:57:35 ERROR Zope.SiteErrorLog 1396393055.010.604317940455 http://localhost:8080/manage_importObject

KeyError: 'AGLSType'

Solution

For now, we set suppress_events argument to False when calling _setObject function inside _importObjectFromFile function.

Note

This package is not fully tested. Use it at your own risk. We believe it only applicable when you want to import a whole Plone site and not part of the site.

Todo

• Make the suppress_events optional. We are not sure setting suppress_events argument to False will have any other effects on other things. This is the next thing we are going to do.
