django中动态新建postgres数据库表

import psycopg2

def create_new_table(table_id):
 conn = psycopg2.connect(database='Test', user='postgres', password='123456', host='127.0.0.1', port='5432')
 cur = conn.cursor()
 print('aaaaa')
 cur.execute('''CREATE TABLE DataFile%s
 (nid INT PRIMARY KEY NOT NULL,
 create_time DATE NOT NULL,
 message_head TEXT,
 message_body_data bytea,
 message_body_param TEXT);''' % table_id)

 print("Table created successfully")

 conn.commit()
 conn.close()
