便利モジュールです。
現段階ではRDS、S3への接続のモジュールになります。
セットアップ
pip install campbel
チュートリアル
dbに接続しよう
from campbel.AWS import Rds as rds
rds = rds.Rds(
db_host = 'DBホスト',
db_user = 'DBユーザー',
db_password = 'DBパスワード',
db_name = 'DB名',
charset = 'utf-8',
debug=False
)
これで接続完了!
sql文を実行してみよう
sql = ''
rds.sqlExecute(sql)
rds.dbClosed()
これで任意のsql文を実行できます!
以下を使うと高速にかつ正確にsql文が実行できます。(内部ではsqlExecute()が実行されています。)
インサートしよう
辞書形式を配列にしましょう。
data_list_array = [
{'name':'ryu', age:27, 'massage':'こんにちは'},
{'name':'koumei', age:26, 'massage':'game'},
{'name':'hyuga', age:21, 'massage':'meshi'},
{'name':'kenjo', age:20, 'massage':'study'},
]
r = rds.insertListExecute('user', data_list_array)
これは
INSERT INTO user (name,age,message) VALUES ("ryu",27,"こんにちは")
INSERT INTO user (name,age,message) VALUES ("koumei",26,"game")
INSERT INTO user (name,age,message) VALUES ("hyuga",21,"meshi")
INSERT INTO user (name,age,message) VALUES ("kenjo",20,"study")
と等価です。
取得してみよう
r = rds.insertListExecute('user', 'name', where='')
data = r.fetchall()
これは
SELECT name FROM user
と等価です。
アップデートしてみよう
r = rds.updateListExecute('user', {'age':8, 'where':'name="ryu"'}, where='where')
これは
UPDATE user SET age=8 WHERE name="ryu"
と等価です。
なお、
r._executedで実行した一番最後のsqlが確認できます。(複数まとめて実行した場合は一番最後のsqlの表示になります。)
もしその都度確認したければ、インスタンスを作る段階でdebug=Trueとしてください。
次はs3に接続してみよう!
from campbel.AWS import S3 as s3
s3 = spython setup.py register3.S3(
access_key = 'アクセスキー',
secret_access_key = 'シークレットアクセスキー',
bucket_name = 'バケット名',
)
これで接続完了です。
S3の/test/とディレクトリを作ろう。
s3.createDir('test/')
ローカルのa.txtをデータを入れよう!
s3.uploadFileToS3(a.txt, 'test/a.txt')
