Source | /packages/mongoose/src/decorators/postHook.ts |
# Overview
function PostHook(method: string, fn?: MongoosePostHookCB<any> | MongoosePostErrorHookCB<any>): Function;
# Description
We can simply attach a @PostHook
decorator to your model class and
define the hook function like you normally would in Mongoose.
import {Ignore, Required} from "@tsed/common";
import {PostHook, Model} from "@tsed/mongoose";
@Model()
@PostHook("save", (car: CarModel) => {
if (car.topSpeedInKmH > 300) {
console.log(car.model, 'is fast!');
}
})
export class CarModel {
@Ignore()
_id: string;
@Required()
model: string;
@Required()
isFast: boolean;
// or Prehook on static method
@PostHook("save")
static postSave(car: CarModel) {
if (car.topSpeedInKmH > 300) {
console.log(car.model, 'is fast!');
}
}
}
