Eloquent deleting model event doesn't fire

replied 9 years ago

I think your missing a param in the where

Program::where('name', '=' ,Input::get('name'))->delete();

No, the default is "=" . It deletes the row in programs table so it works, it just doesn't fire the deleting event and the description isn't deleted

Ok, I've never used it without so it looked off to me.

Not to insult, but have you check the value that is getting returned? Input::get('name')

Maybe the query log can show you the query, dd(DB::getQueryLog());

Or I think you can dump the query with ->toSql(); after the delete()

Humm,

Maybe,

 static::deleting(function()
        {
        $this->description()->delete();
        
        return parent::delete();
        });

I think you can also put a where in there, if you didn't have the relationship setup.

static::deleting(function()
        {
        $this->description()->where('id',$this->id)->delete();
        
        return parent::delete();
        });

Solution

Ok, the previous code just didn't look right.

So after some testing, this finally worked.

In the Program model, I changed it to just this

static::deleting(function($program)
        {
            $program->description()->delete();
        });

To delete,

Program::where('id', 1)->first()->delete();

I had to call with the ->first() or it just didn't work. I found a reference to the ->first() required at https://github.com/laravel/framework/issues/2536

The dd(DB::getQueryLog()); shows all of the queries,

array (size=4)
  0 => 
    array (size=3)
      'query' => string 'select * from `programs` where `id` = ? limit 1' (length=47)
      'bindings' => 
        array (size=1)
          0 => int 11
      'time' => float 0.82
  1 => 
    array (size=3)
      'query' => string 'select * from `descriptions` where `descriptions`.`program_id` in (?)' (length=69)
      'bindings' => 
        array (size=1)
          0 => int 11
      'time' => float 0.94
  2 => 
    array (size=3)
      'query' => string 'delete from `descriptions` where `descriptions`.`program_id` = ?' (length=64)
      'bindings' => 
        array (size=1)
          0 => int 11
      'time' => float 1.44
  3 => 
    array (size=3)
      'query' => string 'delete from `programs` where `id` = ?' (length=37)
      'bindings' => 
        array (size=1)
          0 => int 11
      'time' => float 1.28

You will not have access to $this from a static method.

Yeah, it started looking off to me after a bit

@TerrePorter, thanx ! , it was the "first()" thank you for the reference to https://github.com/laravel/framework/issues/2536 They should mention this in the documentation. I wasted 6 hours because of this :(
