Remove the model from operation

Question

Remove the model from operation

I'm fairly new to angularjs and have a working service. However, I want to move the patient model out of the service and into a separate javascript file. I believe I need to use a factory or service for this task, but I'm not entirely sure how to go about it.

This is my patient.service.js:

(function () {
'use strict';

angular
    .module('beincharge.patient')
    .factory('patientDataService', patientDataService);

patientDataService.$inject = ['$http'];

function patientDataService($http) {
    var service = {
        getData: getData
    };

    return service;

    //////////

    function getData() {
       function patient(d) {
            this.Status = d.Status;
            this.ImageUrl = d.ImageUrl;
            this.PersonId = d.PersonId;
            this.LastName = d.LastName;
            this.MiddleName = d.MiddleName;
            this.FirstName = d.FirstName;
       }

        var data = [
            {
                "Status": "Active",
                "ImageUrl": "http://lorempixel.com/100/100/people/9/",
                "PersonId": 1,
                "LastName": "Pratt",
                "MiddleName": "B",
                "FirstName": "Allie"
            },
            {
                "Status": 'Active',
                "ImageUrl": "http://lorempixel.com/100/100/people/3/",
                "PersonId": 1,
                "LastName": "Pratt",
                "MiddleName": "B",
                "FirstName": "Allie"

            }];

             return  getPatientList(data);

             function getPatientList(data) {
                 var a = [];
                 angular.forEach(data, function (d, i) {
                     a.push(new patient(d));
                 })
                 return a;
             }



    }
}

I want to move the model into a file called patient.model.js:

  (function () {
    function patient(d) {
        this.Status = d.Status;
        this.ImageUrl = d.ImageUrl;
        this.PersonId = d.PersonId;
        this.LastName = d.LastName;
        this.MiddleName = d.MiddleName;
        this.FirstName = d.FirstNa
    }
    return patient;
}());

To implement a factory provider, you need to follow this structure:

angular
    .module('beincharge.patient')
    .factory('Patient', function() {
         return function(data){
             this.Status = data.Status;
             this.ImageUrl = data.ImageUrl;
             this.PersonId = data.PersonId;
             this.LastName = data.LastName;
             this.MiddleName = data.MiddleName;
             this.FirstName = data.FirstName
         }
     });

Then in the Service, you can utilize it as follows:

angular
    .module('beincharge.patient')
    .factory('patientDataService', patientDataService);

patientDataService.$inject = ['$http', 'Patient'];

function patientDataService($http, Patient){
    console.log(new Patient({ Status: 'active' }));
}

If you are looking for a model that you can easily instantiate and reuse, consider creating a basic JavaScript object like the one shown below in a file named patientModel.js:

 function PatientModel() {
        this.Status = "";
        this.ImageUrl = "";
        this.PersonId = "";
        this.LastName = "";
        this.MiddleName = "";
        this.FirstName = "";
    }

Ensure that this file is loaded prior to the controllers or services where you intend to utilize it.

To create an instance of the model, you can do the following:

var patient = new PatientModel();

If needed, you can modify the constructor function to accept parameters so that you can pass any required data through the 'd' parameter.

This approach is suitable for simple and reusable models. The benefit is that you can also use them in your tests without having to depend on hardcoded JSON objects.

It seems like you're attempting to write JavaScript code with a Java style approach. In this case, creating a patient model may not be necessary as the response/data aligns directly with the patient object. A simpler implementation could be as follows:

(function () {
'use strict';

angular
    .module('beincharge.patient')
    .factory('patientDataService', patientDataService);

patientDataService.$inject = ['$http'];

function patientDataService($http) {
    var service = {
        getData: getData
    };
    return service;

    this.getData = function () {
        var data = [
        {
            "Status": "Active",
            "ImageUrl": "http://lorempixel.com/100/100/people/9/",
            "PersonId": 1,
            "LastName": "Pratt",
            "MiddleName": "B",
            "FirstName": "Allie"
        },
        {
            "Status": 'Active',
            "ImageUrl": "http://lorempixel.com/100/100/people/3/",
            "PersonId": 1,
            "LastName": "Pratt",
            "MiddleName": "B",
            "FirstName": "Allie"

        }];
        return data;
    };
}

It is recommended to transfer the app.service(..) code into the patient.model.js file for better organization.

 var app = angular.module('beincharge_patient',[]);

 app.service('patientData',function(){
   var getP = function(d) {
      this.Status = d.Status;
      this.ImageUrl = d.ImageUrl;
      this.PersonId = d.PersonId;
      this.LastName = d.LastName;
      this.MiddleName = d.MiddleName;
      this.FirstName = d.FirstName;
    }
    var service = {
      getP: getP
    }
    return service; 
 });

app.factory('patientDataService',['$http','patientData',function($http,patientData){
  
    var getData = function() {
      var data = [{
          "Status": "Active",
          "ImageUrl": "http://lorempixel.com/100/100/people/9/",
          "PersonId": 1,
          "LastName": "Pratt",
          "MiddleName": "B",
          "FirstName": "Allie"
        },
        {
          "Status": 'Active',
          "ImageUrl": "http://lorempixel.com/100/100/people/3/",
          "PersonId": 1,
          "LastName": "Pratt",
          "MiddleName": "B",
          "FirstName": "Allie"
        }
      ];      
       var getPatientList = function(data) {
        var a = [];
        angular.forEach(data, function (d, i) {
            a.push(new patientData.getP(d));
        })
        return a;
      }
       return  getPatientList(data);
    }
    var service = {
      getData: getData
    };
    return service;
}]);
