1. I have a package "skills" that I'm putting together for my portfolio website.

/* returns Model\Skills */
\Skills\Skills::getAll()

2. Then I have a REST Controller that calls the "skills" package.

\Controller\Rest\Skills::get_main()

3. Next I have an application controller that dupms off the request to a presenter.

\Controller\Skills\Index => \Presenter\Skills\Page

4. Inside the skills presenter.

\Presenter\Skills\Page::view()


    public function view()
    {
        /* put stuff in main content section of the template*/
        $this-&gt;skills = Request::forge('/rest/skills/main')-&gt;execute()-&gt;response()-&gt;body();
    }

5. Finally in the view, I get an error due to a string attached to the body of the request.


        <pre>
        <!--?= print_r($skills); ?-->
        </pre>



        The requested REST method returned an array or object:<br><br>[
	{
		"1": {
			"id": "1",
			"name": "Art \u0026 Design.",
			"slug": "design",
			"url": "\/design",
			"category_id": null,
			"description": "Design is a process that begins with your message and ends with a your creation.",
			"parent_id": null,
			"deleted_at": null,
			"created_at": "1454400961",
			"updated_at": null
		},
		"2": {
			...
		}
	}

here is a link for the GitHub code snippet in question.

REST controllers do not have presenters or views? A REST controller should return a JSON response?

I know rest controllers do not have corresponding views, I am making a hmvc request call from a presenter to a rest api. Then from the presenter I was hoping to pass on the results to its view. I successfully get the DB results back from the rest api, however the body has an a attached string right before the data; "The requested REST method returned an array or object:<br><br>."

That string is preventing the view from being able to parse the data correctly.

UPDATE: If I call the Skills package method ($this->skills->getAll( true )) directly from the controller or from the presenter classes I get a regular model object and everything works well; and I able to pass the info to the view. However, if I call the same Skills package method ($this->skills->getAll( true )) through a rest controller from another controller I get the weird string ("The requested REST method returned an array or object:<br><br>.") attached to the data results and that messes up the bindings in the view.

Next time just give the complete story, so I don't have to guess as to the cause... ;-)

The error message is generated by the REST controller, and caused because it can't process the data being passed to return: https://github.com/fuel/core/blob/1.8/develop/classes/controller/rest.php#L215

Problems:
- there is no format set, so the REST controller doesn't do format conversion, and
- the object you pass doesn't have a toString method that converts the object at runtime

So, It can't handle DB objects, it either needs an array, or a string (if format is set to html).

So if a created a toStiring method in my Skills object would that help?

Thanks for the response, sorry for the confusion at first.

WanWizard

It's probably better you give it a toArray() method, so you can pass an array back, and set the format for the REST controller to json. The controller will then take care of the conversion and the correct result.
