How to prevent changes from services - node.js

Question

I'm using Feathers.js with Mongoose and I want to create a field that cannot be changed by the services.
// account-model.js - A mongoose model
//
// See http://mongoosejs.com/docs/models.html
// for more of what you can do here.
const mongoose = require('mongoose');
require('mongoose-type-email');
module.exports = function(app) {
const mongooseClient = app.get('mongooseClient');
const recovery = new mongooseClient.Schema({
token: { type: String, required: true }
}, {
timestamps: true
});
const account = new mongooseClient.Schema({
firstName: { type: String, required: true },
surname: { type: String, require: true },
phone: { type: String, require: true },
email: { type: mongoose.SchemaTypes.Email, required: true, unique: true },
birth: { type: Date, required: true },
gender: { type: String, required: true },
country: { type: String, required: true },
address: { type: String, required: true },
address2: { type: String, required: false },
city: { type: String, required: true },
postcode: { type: String, required: true },
password: { type: String, required: true },
status: { type: String, required true }
}, {
timestamps: true
});
return mongooseClient.model('account', account);
};
No one can make a post at /account/<id> and change the field status.
This field should only be changed when internally. When some approval service request.
How can I implement this behavior?

Answer 1

This is a perfect use case for Feathers hooks. When accessed externally, in a service method call params.provider will be set so you can check for it and remove the field from data if it is:
module.exports = function() {
return async context => {
if(context.params.provider) {
delete context.data.status;
}
}
}
This hook will be a before hook for the create, update and patch method.
