雄辩的ORM不会在laravel中节省价值

Question

I want to update my data using Eloquent but it gave me some error:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'od_logo.id' in 'where clause' (SQL: select * from `od_logo` where `od_logo`.`id` = 1 limit 1)

Here is my code:

$logo = Logo::find($id);
$logo->logo_logoimg_name       = Input::get('logo_name');
$logo->logo_logoimg_path      = $logo_destinationPath . $logo_filename;
$logo->logo_faviconimg_name = $favicon_destinationPath . $favicon_filename;
$logo->save();

Please find where I do wrong in this code

Answer 1

Because your primary key column is not called id (which is the default Laravel assumes) you have to specify it in your model:

class Logo extends Eloquent {
    protected $primaryKey = 'logo_id';
}

Quote from the docs:

Note: Eloquent will also assume that each table has a primary key column named id. You may define a primaryKey property to override this convention.
