I am getting error: Error: Cannot call Test.create(). The create method has not been setup The PersistedModel has not been correctly attached to a datasource.

Here is my datasource.json:

{
  "db": {
    "name": "db",
    "connector": "memory"
  },
  "mongoDS": {
    "host": "localhost", 
    "port": 27017, 
    "name": "mongoDS",
    "database": "akhiltest",
    "connector": "mongodb"
  }
}

model-config.json:

{
  "_meta": {
    "sources": [
      "loopback/common/models",
      "loopback/server/models",
      "../common/models",
      "./models"
    ],
    "mixins": [
      "loopback/common/mixins",

  }
}

test.js

'use strict';

module.exports = function(Test) {
Test.create({
    "first_name":"akhil"
},function(data){
    console.log(data);
})
};

test.json

Hello. I have been having the same issue and I fixed it by getting rid of the whole Test.create({ "first_name":"akhil" },function(data){ console.log(data); }) Try using the explorer instead at localhost:3000/explorer

If that doesn't solve it, try refactoring all instances of the variable db to mongoDS or the opposite.
