  • pymongo 使用测试

    >>> import pymongo
    >>> uri = "mongodb://recall:123456@oceanic.mongohq.com:10062/must"
    >>> client = pymongo.MongoClient(uri)   #连接到数据库
    >>> db = client.must                    #选择数据库名
    >>> db.collection_names                 #查看所有聚集名,相当与show_tables
    <bound method Database.collection_names of Database(MongoClient('oceanic.mongohq.com', 10062), u'must')>
    >>> table = db.mytable                  #创建聚集
    >>> count = table.count()               #查看聚集中的数目
    >>> count
    0
    >>> monster = {"name":"Dracule","occupation":"Blood Suker","tags":["vampire","teeth","bat"],"data":"19981010"}
    >>> insert_id = table.insert(monster)   #插入数据
    >>> for monster_one in table.find():
    ...     print monster_one
    ...
    ...
    {u'occupation': u'Blood Suker', u'_id': ObjectId('53510fcad6ca3fb153c5681d'), u'data': u'19981010', u'name': u'Dracule', u'tags': [u'vampire', u'teeth', u'bat']}
    >>> print table.find_one({"name":"Dracule"})
    {u'occupation': u'Blood Suker', u'_id': ObjectId('53510fcad6ca3fb153c5681d'), u'data': u'19981010', u'name': u'Dracule', u'tags': [u'vampire', u'teeth', u'bat']}
