How can I convert json to a Laravel Eloquent Model

Question

if I have an Eloquent Model called Post, and the mysql table has:

integer ID, string Text

How do I convert this JSon:

{ post: { text: 'my text' } }

To the relevant Post object that, once received in the controller, I can save to the database like this:

public function store(Post $post)
{
    $post->save();
}

I'm not looking to build the logic that would do that for me, but for the Laravel way (or could it be that there isn't one? I googled it with no relevant results).

Answer 1

fill looks like the method you want. To avoid adding every attribute to your $filled array, which you would need to do if you wanted to use the fill method, you can use the forceFill method.

It accepts an associative array of attributes, so the JSON will have to be decoded, and we'll have to get the inner post key:

$rawJson = "{ post: { text: 'my text' } }";
$decodedAsArray = json_decode($rawJson, true);
$innerPost = $decodedAsArray['post'];

Once we have the decoded data, we can create an instance of the Post eloquent model and call forceFill on it:

$post = new Post();
$post->forceFill($innerPost);
$post->save();

---

This is similar to doing:

$post = new Post();
foreach ($innerPost as $key => $value) {
    $post->$key = $value;
}
$post->save();

Answer 2

Just turn it to array and fill an eloquent

$arr = json_decode($json, true);
$post = new Post;
$post->fill($arr);

Answer 3

Can you try it like this?

public function store($poststuff)
{
    $post = new Post;
    $post->text = $poststuff['text'];
    $post->save();
}

1. Convert json to array

2. Hydrate model from array

   $data = '{  
               "unique_id_001":{"name":"John","email":"[e-mail]"},
               "unique_id_002":{"name":"Ken","email":"[e-mail]"}
             }';
   $object = (array)json_decode($data);
   $collection = \App\User::hydrate($object);
   $collection = $collection->flatten();   // get rid of unique_id_XXX
   
   /*
       Collection {#236 ▼
         #items: array:2 [▼
           0 => User {#239 ▶}
           1 => User {#240 ▶}
         ]
       }
    */
   dd($collection);
