我似乎无法使用MongoKitten从父文档中检索文档数组。
退回文件:
{"updated":{"$date":"2016-01-16T17:58:45.171+11:00"},
"name":"XXXX",
"status":true,
"_id":{"$oid":"57297a76b30bbf896e0a1c55"},
"groups":[
{"name":"Configuration Testing",
"allow_auto_approval":false,
"_id":{"$oid":"5699ea252529119457a40a67"},
"expected_users":30,
"code":"632DZ0"
},
{"name":"Solution Demonstration",
"allow_auto_approval":false,
"_id":{"$oid":"5699ea252529119457a40a68"},
"expected_users":50,
"code":"632GN1"}
]
}
Swift代码迭代子文档数组:
let result = database.collection.findOne()
let groups = result["groups"]
for group in groups {
print("group: \(group["code")")
}
我也试过
for (key, val) in result["groups"].documentValue {
print("Value is \(val)")
}
但这显示语法错误
"Value of type 'Primitive?' has no member 'documentValue'"
答案 0 :(得分:0)
正确的答案是
swedishWords = open("svenskaOrd.txt","r")
for line in swedishWords:
if(len(line.decode("iso8859_10")) >= 4):
print(len(line.decode("iso8859_10")))
print(line.decode("iso8859_10"))
