モデルのインスタンスを保存しようとしていますが、

Invalid EmbeddedDocumentField item (1)

アイテムのIDはどこ1ですか（私は思う）。

モデルは次のように定義されます

class Graph(Document):
    user = StringField(max_length=50, required=True)
    title = StringField(max_length=500)
    description = StringField(max_length=1000)
    # field in error
    graph_nodes = ListField(EmbeddedDocumentField(Graph_Node))
    procedure = ListField(DictField())
    created_on = DateTimeField(default=datetime.datetime.now)

    def __unicode__(self):
        return self.title

    meta = {
        'ordering': ['-created_on'],
        'allow_inheritance': False,
    }


class Graph_Node(EmbeddedDocument):
    id = StringField(required=True, max_length=30)
    button = StringField(max_length=40, required=True)
    parameter = StringField(max_length=50, required=False)
    values = ListField(StringField(max_length=30, required=False))
    wires_out = ListField(StringField(max_length=30, required=False))
    wires_in = ListField(StringField(max_length=30, required=False))

    def __unicode__(self):
        return self.id

    meta = {
        'allow_inheritance': False
    }

    def fill(self, args):
        for k in args.keys():
            if k in self.__dict__['_data'].keys():
                self.__dict__['_data'][k] = args[k]

save()メソッドの呼び出しは次のとおりです。

Graph(user=request.user.username, title=title, 
      description=description, procedure=procedura, 
      graph_nodes=gnlist).save()

saveまた、グラフの作成時ではなく、例外がスローされます。

gnlistは (からpydev debugger)

list: [<Graph_Node: start>, <Graph_Node: 1>, <Graph_Node: end>]

整形式のgnlist[1]ようです（必要に応じて詳細を投稿します）

クエリをトレースしようとしましたmongodbが、プロファイリングされていないようですが、出力は次のとおりです (無関係なログから削除するのに役立つ場合があります)。

解決されたようです：

この問題を見つけました。

の新しい安定版をインストールしましたmongoengine: 0.6.2

再起動後mongoengine、問題の場所がわかりました：

values属性が短すぎてファイルパスを保持できないため、変更しました

values = ListField(StringField(max_length=30, required=False))

に

values = ListField(StringField(max_length=100, required=False))

ありがとうございます
