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']}
