Non-Static (instance) remote methods for loopback

my-model.js

var loopback = require('loopback');

// HINT(s):

module.exports = function(StoreModel) {
  StoreModel.prototype.instanceRemoteMethodSignature = function(cb) {
    console.log('print this instance object: ', this);
    cb(null);
  };
  StoreModel.remoteMethod(
    '__get__instance-remote-method-signature',
    {
      isStatic: false,
      accepts: [],
      http: {path:'/instance-remote-method-signature', verb: 'get'}
    }
  );

  StoreModel.staticMethodSignature = function(id, cb) {
    console.log('print this instance object: ', this);
    StoreModel.findById(id,function(err, instances){
      if(err){
        cb(err);
      }
      console.log('print object: ', instances);
      cb(null);
    });
  };
  StoreModel.remoteMethod(
    '__get__static-method-signature',
    {
      isStatic: false,
      accepts: [
        {arg: 'id', type: 'number', required: true}
      ],
      http: {path:'/:id/static-method-signature', verb: 'get'}
    }
  );

};

I believe @nammaianh is correct the isStatic property for the __get__static-method-signature remote method should be set to true. when you read the code of loopback model.js the whole purpose of the isStatic property is to grab the instance of the model by the foreign key with the models builtin getter function. It also injects the arguments of id in the remote method accepts property. The prototype method receives the instance via the built in getter function when the remote method is set to false. Its also important to note that for every defined remote method, if isStatic is undefined then isStatic is set to true. In conclusion not only should isStatic be set to true but leaving it omitting the property is also a valid option.
