Question

我关注此http://pythonhosted.org/Flask-MongoKit/作为示例

我只是想获得一个Document实例来编写单元测试，但是它没有用。这是测试代码：

import unittest
from tests import app, db, ctx
from word.models import Word

class ModelWordTestCase(unittest.TestCase):

    def setUp(self):
        pass

    def test_model_word(self):
        print db.Word

        word = db.Word()

        self.assertIsNotNone(word)

    def tearDown(self):
        pass

Word Class

from flask.ext.mongokit import Document
from core import db

@db.register
class Word(Document):
    __collection__ = 'words'
    use_dot_notation = True

    STATUS = {
        "approved" : 1,
        "pending" : 0,
        "rejected" : -1,
    }

    structure = {
        'lang': unicode,
        'local': unicode,
        'pronunciation' : unicode,
        'meaning': unicode,
        }

令人惊讶的是db.Word在使用print db.Word语句打印时存在，但是无法调用它来创建新实例，就像我在上面提到的教程中所做的那样。这是测试的输出：

Collection(Database(MongoClient('localhost', 27017), u'words_test'), u'Word')

如何修复此问题并获取Word文档的实例，以便我可以创建并保存记录。

我认为您在测试中使用了错误的数据库实例。您应该使用用于注册模型的相同数据库实例。所以，我不知道你的代码是如何构建的，但是，乍一看，你应该从模型中导入数据库：

>>> from word.models import db
>>> db.Word.find()

或者

>>> from core import db

Flask MongoKit'Collection'对象不可调用
