#Validation from Server for Angular Agility

Angular Agility form validation that is retrieved from Web API and DTO classes in the form of the JSON object that AA expects.

NuGet Package

##Blog Angular Agility: AngularJS Validation Pulled from Web API

##Usage Typically, the following code would reside on the Web API controller code:

	public IHttpActionResult GetValidations(string dtoObjectName, string jsonObjectName)
	{
		var valHelper = new ValidationHelper();
        object jsonObject = valHelper.GetValidations(dtoObjectName, jsonObjectName,
			"Namespace.If.Doesnt.Match.Assembly", useCamelCaseForProperties, "DTO.Assembly.Name");
	
	    return Ok(jsonObject);
	}

dtoObjectName is the name of the class in your DTO assembly.
jsonObjectName is the name of the model object on your website.
"Namespace.If.Doesnt.Match.Assembly" is an alternate namespace...by default is uses DTO.Assembly.Name.
"useCamelCaseForProperties" is a bool indicating if the helper should provide case alteration to property names to produce camel case.
"DTO.Assembly.Name" is the name of the assembly to load for reflecting the DTO properties that have validation attributes.

##Using GetValidationsParms to call GetValidations If your project is using a separate assembly for resource files, use the GetValidationsParms version of GetValidations. The call would now look like this:

	public IHttpActionResult GetValidations(string dtoObjectName, string jsonObjectName)
	{
		var valHelper = new ValidationHelper();
		var parms = new GetValidationsParms(dtoObjectName, jsonObjectName);
		parms.DtoAlternateNamespace = "Namespace.If.Doesnt.Match.Assembly";
		parms.DtoAssemblyNames = "DTO.Assembly.Name";
		parms.UseCamelCaseForProperties = true;
		parms.ResourceNamespace = "Namespace.For.Resource";
		parms.ResourceAssemblyName = "Resource.Assembly.Name";

        object jsonObject = valHelper.GetValidations(parms);
	
	    return Ok(jsonObject);
	}

##DTO Example

    namespace AATestAPI.Models
    {
    public class ValidationTest
    {
        [Required]
        public string Name { get; set; }

        [Phone]
        public string Phone { get; set; }

        [Url]
        public string Website { get; set; }

        [CreditCard]
        public string CreditCard { get; set; }

        [EmailAddress]
        public string Email { get; set; }

        [MaxLength(5)]
        public string MaxLengthTest { get; set; }

        [MinLength(2)]
        public string MinLengthTest { get; set; }

        [Range(1, 5)]
        public int RangeTest { get; set; }

        [RegularExpression(RegexConstants.Integer, ErrorMessage = "Must be an integer")]
        public string IntegerString { get; set; }

        [StringLength(10, MinimumLength = 2)]
        public string StringLengthTest { get; set; }
    }
	}

##AngularJS Website ###View This is a typical Angular Agility form:

<div class="page-header">
    <h1>Angular Agility Validation From Server</h1>
</div>
<div aa-configured-form validation-config="formconfig" class="form-horizontal" ng-form="aatest">
    <input aa-field-group="model.Name" />
    <input aa-field-group="model.Phone" />
    <input aa-field-group="model.Website" />
    <input aa-field-group="model.CreditCard" />
    <input aa-field-group="model.Email" />
    <input aa-field-group="model.MaxLengthTest" />
    <input aa-field-group="model.MinLengthTest" />
    <input aa-field-group="model.RangeTest" type="number" />
    <input aa-field-group="model.IntegerString" />
    <input aa-field-group="model.StringLengthTest" />

    <button aa-submit-form="submit()" type="submit" class="btn btn-primary">Submit</button>
 </div>

###UI-ROUTER State Definition Use the 'resolve' property and return a promise so that the controller doesn't get created until the validation is retrieved from the server. See this excellent explanation of this technique: How to force AngularJS resource resolution with ui-router. Of course this assumes you are using ui-router.

    angular.module('app', [
        'ui.router',
        'ui.bootstrap',
        'aa.formExtensions',
        'aa.formExternalConfiguration',
        'aa.notify',
        'aa.select2'
    ])
    .config(['$stateProvider', function ($stateProvider) {
        $stateProvider.state('aatest', {
            url: ''
            , resolve: {
                validationService: 'validationService',
                validationData: function (validationService) {
                    var valData = validationService.getValidations('ValidationTest', 'model');
                    return valData;
                }
            }
            , views: {
                'content@': {
                    templateUrl: 'aatest.html'
                    , controller: 'aatestController'
                }
            }
        });
    }]);

###Controller The controller now can inject validationData since it was resolved in the router definition.

    angular
        .module('app')
        .controller('aatestController', aatestController);

    aatestController.$inject = ['$scope', 'validationData'];

    function aatestController($scope, validationData) {
        activate();

        function activate() {
            $scope.model = {};
            $scope.formconfig = angular.isUndefined(validationData) ? undefined : validationData.data;
        }
    }
