Laravel Eloquent ignore attribute if not in table during insert

Question

I have a model Foo that corresponds to a table with the following columns.

id
description
user_id

I\'m setting the attributes of the Foo model individual

Answer 1

Just add $bar as an attribute in your foo class:

class Foo extends Model
{

  public $bar;
  //...

now you can use save() and Laravel will not try to store bar in the DB.

Explanation:

If you call save() on a model, only those attributes that are in the array $model->attributes will be saved to the database. If you define $bar as an attribute in the class Foo, then $foo->bar ="xyz" will never end up in the array $model->attributes.

However, if you do not have declared such an attribute for Foo, then __set() is called because you try to save something in an inaccessible property.

You may check out Laravel\Illuminate\Database\Eloquent\Model.php:

/**
     * Dynamically set attributes on the model.
     *
     * @param  string  $key
     * @param  mixed  $value
     * @return void
     */
    public function __set($key, $value)
    {
        $this->setAttribute($key, $value);
    }

which basically calls

$this->attributes[$key] = $value;

from Laravel\Illuminate\Database\Eloquent\Concerns\HasAttributes.php.

Now $foo->bar ="xyz" will end up beeing in $foo->attribute['bar'] and this is why save() crashes with ..this column does not exists...
