angular-server-form provides a directive and service to simplify server-side validation. It provides automatic propagation of server-side errors on your forms.

You can install angular-server-form with bower:

bower install angular-server-form

Otherwise you can download the files from the dist folder and include them in your project.

Then you must include angular-server-form as a module dependency.

var app = angular.module('app', ['angular-server-form']);

To view examples do the following:

1. Clone this repo
2. Run npm install and bower install
3. Run npm run examples
4. Navigate to 127.0.0.1:9999 with your browser

You can view the source for all examples in the examples folder.

server-form serializes your form into an object, submits it, and applies errors on the form controller if a 422 response is received.

• Serializes the form controller on submit by calling serverForm.serialize
• Submits the serialized form using serverForm.submit
• Does not allow you to submit the form if it is already submitting

• url : String (required) - url to which the form must be submitted
• method : String - http method to use when submitting the form, default: POST
• on-success : Function - callback for when form submission is successful
• on-error : Function - callback for when form submission is unsuccessful

Controller

$scope.model = {
  favorite: 'banana'
};

View

<form name="fruits" server-form url="/fruits">
  <label>
    Favorite: <input name="favorite" ng-model="model.favorite" />
  </label>
  <button type="submit">Submit</button>
</form>

serverForm is a service to assist in handling forms with server-side validation.

Inject serverFormProvider to set the following:

• logging : Boolean - controls whether or not to log a message when a server error cannot be rendered, default: true
• errorsKey : String - object key to check for form errors on the data object of any 422 server response, when set to a falsy value it will use the data object directly, default: errors

Example

angular.module('app')
.config(function (serverFormProvider) {
  serverFormProvider.logging = true;
  serverFormProvider.errorsKey = 'errors';
});

• Takes a form controller and returns a form data object.
• If the form controller has a name, the data object's root will be the form name.
• Form controls must not start with $

Params:

• form : Object (required) - an instance of NgFormController

Example:

/* Nameless form:
<form>
  <input name="input" ng-model="input"/>
</form>
*/
serverForm.serialize(namelessFormController);
/* Returns:
{
  input: ""
}
*/

/* Named form:
<form name="name">
  <input name="input" ng-model="input"/>
</form>
*/
serverForm.serialize(namedFormController);
/* Returns:
{
  name: {
    input: ""
  }
}
*/

• Applies errors on the form controller's fields
• If logging is enabled, it'll log a warning when a server error cannot be rendered on the form
• Sets form controls to pristine
• Sets the server $error value to true
• Sets the error message on the $server value of the form controls to the

Params:

• form : Object (required) - an instance of NgFormController
• errors : Object (required) - object that matches the form's structure, values must be strings, arrays of strings (will be concatenated with , ), or objects (for nested forms)

Example:

/* Form:
<form name="name">
  <input name="input" ng-model="input"/>
</form>
*/

/* With errors object that has root */
serverForm.applyErrors(firstFormController, {
  name: {
    input: "cannot be blank"
  }
});

firstFormController.input.$server
// "cannot be blank"

firstFormController.input.$pristine
// true

/* With errors object that has no root */
serverForm.applyErrors(secondFormController, {
  input: "cannot be blank"
});

secondFormController.input.$server
// "cannot be blank"

secondFormController.input.$pristine
// true

• Sets all $server errors on form controller's fields to empty string
• Sets form controller's fields to pristine and validity of server to true

Params:

• form : Object (required) - an instance of NgFormController

• Calls clearErrors on form
• Sets $submitting to true, sets $saved to false
• When it finishes submitting it sets $submitting to false
• If resolved succesfully it sets $saved to true, otherwise it's set to false
• If the status code is 422 it will call applyErrors on the form with the errors data response

Params:

• form : Object (required) - an instance of NgFormController
• config : Object (required) - $http configuration object

Returns:

• $http promise object

The getting started steps are always the same:

1. Clone the repo
2. Run npm install
3. Run bower install

After you have the dependencies installed:

• Run unit tests with npm run unit
• Run e2e tests with npm run e2e
• Run both with npm test
