php - Property [title] does not exist on this collection instance

I am following Laracasts' videos: Basic Model/Controller/View Workflow.

I have a table holds contact information.

CREATE TABLE `about` (
`id` int(10) UNSIGNED NOT NULL,
`title` varchar(500) COLLATE utf8_unicode_ci NOT NULL,
`content` text COLLATE utf8_unicode_ci,
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci

I am trying to pass data to view using the following code in the controller file:

public function index()
{
    $about = Page::where('page', 'about-me')->get(); //id = 3

    return view('about', compact('about'));
}

When I try to show the code as shown below,

@section('title')
    {{$about->title}}
@stop

@section('content')
    {!! $about->content !!}
@stop

I get error that says:

Property [title] does not exist on this collection instance. (View: E:laragonwww ewsite esourcesviewsabout.blade.php)

But if I change the retrieving method in the controller file, it works.

public function index()
{
    $about = Page::find(3);

    return view('about', compact('about'));
}

When I use dd($about) in the first case (where()->get()) the data is encapsulated by an array. In the second case (find(3)) it displays data as expected.

What am i doing wrong?

When you're using get() you get a collection. In this case you need to iterate over it to get properties:

@foreach ($collection as $object)
    {{ $object->title }}
@endforeach

Or you could just get one of objects by it's index:

{{ $collection[0]->title }}

Or get first object from collection:

{{ $collection->first() }}

When you're using find() or first() you get an object, so you can get properties with simple:

{{ $object->title }}
