How can I make laravel casting array on the model? - php

Question

I try like this
Data type of votes_detail in database is json
My model like this :
<?php
class Store extends Model{
protected $fillable = [ ...,'votes_detail',...];
protected $casts = [
'votes_detail' => 'array',
];
}
My controller like this :
$store = Store::find($id)
$votes_detail = $store->votes_detail;
dd($votes_detail);
The result of dd($votes_detail) is :
{"1": "1", "5": "2"}
Why the result is still json?
The result should be an array
Whereas I've set the array in cast model
How can I solve this problem?

Answer 1

You could use Laravel accessors. In you model define a method called exactly getVotesDetailAttribute($details):
public function getVotesDetailAttribute($details)
{
return json_decode($details, true);
}
then when you will call $store->votes_detail you will get the expected result.
After that you can use mutators to convert an array back to JSON when it is saved back in the DB. Define the method setVotesDetailAttribute($value) as follows:
public function setVotesDetailsAttribute($value)
{
$this->attributes['votes_detail'] = json_encode($value);
}

You can easily do it by converting your data to the array by using toArray() function. So it should be like
$store = Store::find($id)->toArray();
//$store contain a array.
$votes_detail = $store['votes_detail'];
make it dd($votes_detail) and get your desire result.

I think you are storing array data after json_encode() to a column which is not defined as json() in the migration like:
$table->text('votes_detail');
or
$table->integer('votes_detail');
And seems you have defined votes_detail as string, number or something else.
This is the reason behind your problem. So, define column type as json in migration like:
$table->json('votes_detail');
And then refresh your migration, your casting in the model will work and you will get your desired array.
