book model

export default (sequelize, datatypes) => {   const books = sequelize.define('book', {    title: {       type: datatypes.string,       allownull: datatypes.false,     },     isbn: {       type: datatypes.text,       required: true,     },     total: {       type: datatypes.integer,       required: true     },     prodyear: datatypes.string,     catid: datatypes.integer,     cover: datatypes.string,     author: datatypes.string,     description: datatypes.text   }, {     classmethods: {       associate: (models) => {         // associations can defined here          books.hasmany(models.rentedbook, {       foreignkey: 'bookid'         });         books.hasone(models.category, {           foreignkey: 'catid',           ondelete: 'cascade'         });       }    }   });   return books; }; 

rented book model

export default (sequelize, datatypes) => {   const rentedbook = sequelize.define('rentedbook', {     bookid: datatypes.integer,     userid: datatypes.integer,     toreturndate: datatypes.date,     returndate: datatypes.date,     returned: {       type: datatypes.boolean,       defaultvalue: false     }   }, {     classmethods: {       associate: (models) => {     // associations can defined here         rentedbook.belongsto(models.book, {           foreignkey: 'bookid',           ondelete: 'cascade'         });         rentedbook.belongsto(models.user, {           foreignkey: 'userid',           ondelete: 'cascade'         });       }     }   });   return rentedbook; };
