无法访问Laravel中的对象属性

Question

I started learning Laravel since yesterday and face some difficulties to get property of an object.

Here is the class (created with artisan ) :

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Task extends Model
{
    public $description;
    public $completed;
    public $timestamps = false;

    public function isComplete()
    {
        return $this->completed;
    }
}

And here is the issue :

>>> $tasks = App\Task::all();
=> Illuminate\Database\Eloquent\Collection {#654
     all: [
       App\Task {#652
         id: "1",
         description: "Learn Laravel",
         completed: "0",
       },
     ],
   }
>>> $tasks[0]->id
=> 1
>>> $tasks[0]->description
=> null

Why can I access the id but can not access the description ?

Answer 1

Field description is empty because you have public field in your model with the same name:

public $description;

Just remove it and you will be able use value of the field description from the DB table of your model.

Answer 2

You have to make your model property as follow

protected $table = 'your table name';
protected $primaryKey = 'id';
protected $fillable = ['description','completed'];

I hope this will work for you.
