AttachAction doesn't work

I have a simple one-to-many relation between Clients and Contacts. I want to select existing contacts for a Client from the RelationManager. If I use the AttachAction from the Header Actions I get an error, which is available here: https://flareapp.io/share/lm2DjkL7#F70 Call to undefined method Illuminate\Database\Eloquent\Relations\HasMany::getRelatedKeyName() Not sure what I am doing wrong?

Your relation should be a BelongsToMany

Hmm... It is One Client that Has Many Contacts? Not sure I understand. This is in my Client model:

public function contacts()
    {
        return $this->hasMany(Contact::class);
    }

public function contacts()
    {
        return $this->hasMany(Contact::class);
    }

And this is in my Contact model:

public function client()
    {
        return $this->belongsTo(Client::class);
    }

public function client()
    {
        return $this->belongsTo(Client::class);
    }

protected static ?string $inverseRelationship = 'client';

Daniel Plomp•15mo ago

Is that a workaround, or something that I need anyways? I just try to understand what I am doing wrong. The HasMany should be the right relationship type, right?

Dennis Koch•15mo ago

It something you need if the guessed relationship doesn't match

Daniel Plomp•15mo ago

OK. I'll try it.

Dennis Koch•15mo ago

I still think it's a BelongsToMany, but I might be wrong 😅

Daniel Plomp•15mo ago

I see you point now. Maybe you are right. If it is just one-to-many the CreateAction would be sufficient. With a Many-To-Many you would need the AttachAction I guess. I don't have a pivot table. Sorry, I led you astray following a completely different relationship type 😅

Dan Harrin•15mo ago

you have a one-to-many AssociateAction is for when you have contacts with client_id=null and want to associate them to the current client
