loopbackjs How to customize built-in user model?

Question

I'm new at loopback and i'm trying to customize the User built-in model by denying access to all methods of the customized user model (for testing) and the result is that i can access to some of the user methods (like create user).

{
  "name": "user",
  "base": "User",
  "idInjection": true,
  "properties": {},
  "validations": [],
  "relations": {},
  "acls": [
    {
      "accessType": "*",
      "principalType": "ROLE",
      "principalId": "$everyone",
      "permission": "DENY"
    }
  ],
  "methods": []
}

what am i missing?

Answer 1

Customizing built-in models is actually not a good idea. Create a new model which extends the user model. The built-in user model resides in node_modules/loopback. If you make any change and push it to Git you probably might loose the change, as it most likely to be ignored during push.

Answer 2

You can always extend the behaviour of the built-in models and create your custom end-points as well. You can read on their docs. https://docs.strongloop.com/display/public/LB/Remote+methods

Answer 3

There is a somewhat known bug in the current version of Loopback Datasource juggler that is causing this.

You can go to nodeModules > loopback > common > models> User and there change the ACL on create. This should block the method for now.

Longer term - 1) Loopback docs say that the model that you extend from User should have a different name like person or AppUser is my case. This did make the ACL thing easier to think about the bug remained. There is a fix that has been approved and should be out with the next version of the Juggler. But it could take time.

In the meantime, you can set up a gulp task to delete all ACLs from the loopback default models. This will make sure that any ACLs you set in your model definition take priority.

Also - just saw the comments above and Mr Chacha's solution seems much better to me.
