pymongo 使用测试

>>> import pymongo
>>> uri = "mongodb://recall:[email protected]: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']}
