1. When inserting a database, write less than one field. Ps: Check whether the fields in the database are not empty or foreign keys.

2. When two data tables need to be operated consecutively in the same view, the relationship between the Foreign keys of the two tables is optimistic before operating the table. For example, an order table order_info and an order item table order_goods have a foreign key order associated with the order table. When both tables are empty, insert a data entry to order_goods, because order_id in the order table does not exist, an error is returned.
