研究方向
Examine the association definition files in the repository to locate where foreign key constraints are currently handled. Look for existing options like 'onUpdate' and add a similar 'onDelete' option supporting 'RESTRICT', 'CASCADE', and 'SET NULL'. The change will likely be in the model generation or association configuration module, such as lib/models/associations.js.
