Relation with multiple select - how show pre-selected values

[info170]

Please help, I couldn't find the solution.
I got the model News, model Project and many2many table news_project.
And the Layout Relation
Relation::make('news.project_id.') ->fromModel(Project::class, 'code') ->multiple() ->title('Project')
It works properly for first time selection and storing data.
But how describe make parameter to show pre-selected multiple values project_id if it stores in many2many table (not in news table) ?

i think you should use plural form of project_id as 'news.project_ids.' then you should load your model with that project_ids using 'with' in your model public function project_ids(){ return $this->belongsToManyBlaBla() } then this will probably show up.

A little workaround is, load your ids and their labels by hand, then give Relation::make(blabla)...->value($idsFetchedByHand)

Thanks a lot.
What I was need to know - "value" method.
And now it works properly in such syntax:
`

            Relation::make('news.project_id.')
                ->fromModel(Project::class, 'code')
                ->value($this->news->projects()->pluck('project_id'))
                ->multiple()
                ->title('Project'),

`
