Sequelize Hooks- Previous data values for afterBulkUpdate










0














I am trying to create a hook beforeBulkUpdate and get new and previous values of a field. I tried using .reload() on the model and _previousDataValues but they only work on instances and not bulk create and update (I'm using bulk update). Is there a way to get the previous value of field using the beforeBulkUpdate hook?



beforeBulkUpdate: (person) => 
console.log(person.name) // 'John' (new name)
Person.findOne( where: id: input.id ).then(person =>
person.reload().then(() =>
console.log(person.name) // 'John' (expected old name, but returns new name)
)
)

          Solved it by passing individualHooks:true to the call.



          Model.update(id: input.id, individualHooks: true);


          And:



          hooks: 
          beforeUpdate: (instance, options) =>
          console.log(instance.dataValues); // new values
          console.log(instance._previousDataValues); // current values
