Overriding mongoose query for a specific model

Question

I want to automatically add a query option for all queries related for a specific mongoose model without affecting other models

I saw this answer where Mongoose.Query is patched and that will affect all mongoose models.

Answer 1

I was able to do this for my soft deleted items. Haven't tested it extensively yet though.

function findNotDeletedMiddleware(next) {
    this.where('deleted').equals(false);
    next();
}

MySchema.pre('find', findNotDeletedMiddleware);
MySchema.pre('findOne', findNotDeletedMiddleware);
MySchema.pre('findOneAndUpdate', findNotDeletedMiddleware);
MySchema.pre('count', findNotDeletedMiddleware);
