Sometimes my document has a field with null values.
- How to check if a value inside a field is an empty string?
- How to iterate over all documents and delete the document field if it has a zero string value?
- Do I have to delete this field for this document so that I can do this to find an empty field?
for i in v7.find({"eng":{"$exist":True}})
An example of my document structure is this:
{ "_id" : ObjectId("50fd55c1161747668078fed6"),
"dan" : "Hr. Hänsch repræsenterede Dem dér .",
"deu" : "Der Kollege Hänsch hat Sie dort vertreten .",
"eng" : "Mr Hänsch represented you on this occasion .",
"fin" : "Kollega Hänsch edusti teitä siellä .",
"ita" : "Il collega Hänsch è intervenuto in sua vece .",
"md5" : "336b9cd1dc01ae0ff3344072d8db0295",
"uid" : 2100986 }
{u'uid': 104,
u'fre': u"Je crois que la pr\xe9vention est d' une importance capitale , et ce non pas \xe0 cause des criminels \xe0 la t\xeate du pouvoir .",
u'eng': u'',
u'dan': u'Som hr .',

u'ita': u"L' emendamento n .",

u'_id': ObjectId('50fd381f161747668058f043'),
u'fin':
