Mongoose pre middleware with findByIdAndDelete

Im following a course on Udemy for Node js. There mongoose pre middleware is used with remove like this. 

ReviewSchema.pre('remove', function() {
  // code goes here
});

But my implementation is different and I want to use findByIdAndDelete. This is my code.

ReviewSchema.pre('findByIdAndDelete', function() {
  // code goes here
});

But this one doesn't trigger. I tried to console.log inside this, but it doesn't trigger. What am I doing wrong here?

I believe that middleware doesn't exists. Take a look at the documentation.

But, if you go to findByIdAndDelete's documentation then you will see that it triggers the following middleware:

  • findOneAndDelete

So, instead of ReviewSchema.pre('findByIdAndDelete', ...) try ReviewSchema.pre('findOneAndDelete', ...).

There seems no middleware for findByIdAndDelete.

But since findByIdAndDelete triggers the findOneAndDelete, you can take advantage of this.

So your ReviewSchema must be updated like this:

ReviewSchema.pre("findOneAndDelete", function() {
  console.log("called!!!");
});

Also it is a good idea to include next() so that it does not stop the rest of the code in your middleware function from executing.

ReviewSchema.pre("findOneAndDelete", function(next) {
  console.log("called!!!");
  next();
});
