Question

I come from cakePHP where it is possible to have every get or list query to include a standard where "something = something" in the Model. Per function in the controller this can be ignored, but for all others this is used.

Now I am wondering how to do this in Laravel 5. I would like to add something like below code in the Model or in the Controller (but preferably in the Model):

public function __construct(Page $page) {
    $page->where('is_active', 1);
}

So that when running any query on the pages table it will only give me active pages. Except when I manually add where('is_active', 0) or something else to include all active and inactive pages.

Any help would be very appreciated

您可以通过在模型上使用查询范围来实现您想要的大部分内容。

你在你的模特中放了这样的东西：

/**
 * Scope a query to only include active users.
 *
 * @return \Illuminate\Database\Eloquent\Builder
*/
public function scopeActive($query)
{
    return $query->where('active', 1);
}

然后当你想要使用它时，你会做这样的事情：

$users = App\User::active()->orderBy('created_at')->get();

它没有为所有查询设置默认值，但它可能是更好的长期解决方案。文档在这里：http://laravel.com/docs/5.1/eloquent#query-scopes
