Laravel Code Tips #3

A brief information

A quick explanation of how Laravel forwards static calls from eloquent models to the eloquent builder.

User::where('is_active', '=', true);
namespace Illuminate\Database\Eloquent;
class Builder implements BuilderContract
{
public function where($column, $operator = null, $value= null, $boolean = 'and')
 {
   // Some laravel code
 }
}

For more information

1-) whereColumn()

Want to find posts that have been updated after they were created? ✍️

Or posts where the slug and title is identical?

Laravel’s whereColumn() is pretty handy! It’s makes it super easy to create this kind of queries.

Post::query()
   ->whereColumn('updated_at', '>', 'created_at')
   ->get();
Post::query()
   ->whereColumn('title', 'slug')
   ->get();

2-) Adding simple methods on your models

Laravel tip: Adding simple methods on your models can make your code at lot more readable.

class Message extends Model
{
 
 public function markAsRead()
 {
   $this->read_at = now();
   $this->save();
 }
}
public function show(Message $message)
{
 
 $message->read_at = now();
 $message->save();
$message->markAsRead();
return $message;
}

3-) If the model relationship returns null

#Laravel Tip: If the model relationship returns null, you may set a default values to the related model as a fallback Here is an example:

public function user()
{
 return $this->belongsTo(User::class)
    ->withDefault([
     'name' => 'Guest Author :)',
    ]);
}
