This project has been moved to gitlab: https://gitlab.com/scku208/peegee
A PostgreSQL client based on psycopg2
pip install peegee
import peegee as pg
pgm = pg.Manager(host='localhost', database='postgres', port=5432,
user='postgres', password='yourdatabaseloginpassword')
# about get info
pgm.getCurrentDatabase() # where am I -> 'postgres'
pgm.getCurrentSchema() # think as default schema -> 'public'
pgm.getAllDatabases() # list of database name, e.g. ['postgres', 'other_db', ...]
pgm.getAllSchemas() # ['public', 'you_create_schema1', ...]
pgm.getAllTablesInSchema() # return a list of all table name in "default" schema ('public')
pgm.getAllTablesInSchema('another_schema') # specify schema name
# about create
pgm.createSchema('schema_name') # commit immediately by default
pgm.createTable('table_name', column_name=['C1', 'C2', 'C3'],
column_type='text', schema=None, if_exists='skip', commit=True)
# create table named 'table_name' in default schema,
# has columns 'C1', 'C2', 'C3' with all data type "text"
# if table already exists, just skip, then commit it!!
# about check, return True or False
pgm.isDatabaseExists('db_name')
pgm.isSchemaExists('schema_name')
pgm.isTableExists('table_name', schema=None) #default schema
# about others
pgm.switchDatabase('db_name') #link to other database
pgm.createDatabase('new_db_name') #create db~
The method of peegee's Manager, which including "assign column data type", that psycopg2 does not provide safety method directly, I am trying to prevent SQL injection by converting "column data type" from SQL keyword to PostgreSQL identifier.
