Why this is happeing,.\I am asking, The real case why fuelphp shows this error?

i have found some solutions, and causes.

one of the deleting table has after_load observer which checks parent table data and creating some custom property. I think the parent is deleted before child. the child is querying to somehow parents which exactly not exist. when i commentout the after_load observer.. the row is deleted. ,any how.. this is the cause. any news?

Most common cause is incorrect definition of relations, i.e. the belongs_to is defined on the wrong model.

Afaik the code deletes parents after children, because you would run into problems with database constraints if you do it the other way around. It does require the relation to be defined correctly.

Also,

You get this error if you are trying to modify the object while it is in the process of being deleted. So your observers should check the frozen state before modifying them.

if ( ! $model->frozen())
{
// change the object.
}
