使用FSS获取Plone 3.x中图像字段的值

Question

I'm trying to migrate an old Plone 3.3 site that uses FileSystemStorage using Mikko's Simple JSON export script .

Everything runs fine, except for the absence of a value on the image fields, which are returned as empty strings ( '' ):

[
    ...
    {
        "allowDiscussion": false, 
        "contributors": [], 
        "creation_date": "2009-11-04T15:15:36-02:00", 
        "creators": [
            "johndoe"
        ], 
        "description": "", 
        "effectiveDate": null, 
        "excludeFromNav": false, 
        "expirationDate": null, 
        "id": "banner_vertical.jpg", 
        "image": "", 
        "language": "", 
        "location": "", 
        "modification_date": "2009-11-04T15:15:37-02:00", 
        "portal_type": "Image", 
        "relatedItems": [], 
        "rights": "", 
        "subject": [], 
        "title": "Banner vertical", 
        "urlLegend": "http://"
    },
    ...
 ]

Any hint?

( iw.fss version used is 2.8.0rc5).

Answer 1

FSS was not known or used by the site for which the script has been made.

You might want to retrofit convert() and other methods to support your use case.
