[Product-Developers] Re: using contentmigration InlineFieldActionMigrator tranform doesn't seem to work

[David Bain]

Okay... I've adjusted makeLower and it works now:

def makeLower(obj, val, **kwargs):
    s = str(val)
    import pdb;pdb.set_trace()
    s = s.lower()
    setattr(obj,kwargs['fieldName'],s) #perhaps should be newFieldName
    obj.update()
    return obj.getCountry() #val

I'm sure there is a prettier way, but it works.
