Laravel - How to detach with condition?-CodePudding

I want to detach values from a model based on a condition. I want to detach all people from the organization whose type is 3, which are workers. But when I try to do so, it detaches all people, not taking into account the where condition.

here are my relationships:

Class: Organization

public function people()
{
    return $this->belongsToMany(People::class, 'organization_people')
}

public function workers()
{
    return $this->people()->where('type', 3); //returns all workers
}

public function detachWorkers()
{
    $this->workers()->detach(); // this detaches all people, I want it to detach only workers
}

CodePudding user response：

You need to do this:

public function people()
{
    return $this->belongsToMany(People::class, 'organization_people')
}

public function workers()
{
    return $this->people()->where('type', 3);
}

public function detachWorkers()
{
    $this->people()->detach($this->workers); 
}

IIUC Laravel will not append that where contstraint onto the detach. Howerver, it will append any contstraints that you place on the pivot table directly, such as $this->people()->wherePivot('type', 3); assuming that you have a type column on the pivot table.
