修改配置文件：

default-time-zone = '+8:00'

django框架错误：

django.db.utils.IntegrityError: (1452, 'Cannot add or update a child row: a foreign key constraint fails (db1.app01_author, CONSTRAINT app01_author_author_date_id_38cd4559_fk_app01_authordate_id FOREIGN KEY (author_date_id) REFERENCES app01_authordate (id))')
