# Contacts Handler

Let's put all the layers together and make the handler talk to the model. I create different saving approaches, to showcase different integration techniques:

```
coldbox create handler name=Contacts actions=index,newContact,create,save --open
```

Spice it up now

```javascript
component{

    // Dependency Injection
    property name="contactService" inject="ContactService";

    function index(event,rc,prc){
        // Get all contacts
        prc.aContacts = contactService.list();
        event.setView("contacts/index");
    }

    function newContact(event,rc,prc){
        event.setView("contacts/newContact");
    }

    function create(event,rc,prc){
        var contact = populateModel( "Contact" );
        // validate it
        var vResults = validateModel( contact );
        // Check it
        if( vResults.hasErrors() ){
            flash.put( "errors", vResults.getAllErrors() );
            return newContact(event,rc,prc);
        }
        else{
            flash.put( "notice", "Contact Created!" );
            setNextEvent("contacts");
        }
    }

    function save(event,rc,prc){
        event.paramValue("contactID",0);
        var contact = populateModel( contactService.get( rc.contactID ) );
        // validate it
        var vResults = validateModel( contact );
        // Check it
        if( vResults.hasErrors() ){
            flash.put( "errors", vResults.getAllErrors() );
            return newContact(event,rc,prc);
        }
        else{
            flash.put( "notice", "Contact Saved!" );
            setNextEvent("contacts");
        }
    }
}
```

Now that you have finished, go execute the contacts and interact with it.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://coldbox.ortusbooks.com/v4.x-1/the-basics/models/coding-solo-style/contacts-handler.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
