Form Select relationship with custom search

hi. I want to implement the custom search to the form select component. How can I archive this? I've tried to use the component relationship() with modifyQueryUsing: ($query, $search) callback function but no luck. Context: for example, I have a product, which belongs to an order, and product also belongs to an category. I want to make a select field inside create/edit an order resource, with the functional search with product code, product name, and category's name for example.

Ok actually makes sense, let me think Got it, pass in $get to the modifyQueryUsing 
modifyQueryUsing: fn ($state, $search, $query, $get) => $query->where('product_code', $get('product_code')))
modifyQueryUsing: fn ($state, $search, $query, $get) => $query->where('product_code', $get('product_code')))

Let me try this. Thank you for your time. And btw, do you know how to create a new option from the Form's Select fields without any relationship define to the component? Whenever I want to add new option, the app thrown me the error 'Call to a member function isRelation() on null'.

What is your relationship method I can't see how that would happen tbh.... creating an option just creates it directly

this is not what I'm looking for. I wantted to perform the search from within the Select component. Like Forms\Components\Select::make('product')->relationship('orderProducts', 'product_name')->searchable(true) and then perform the search (when the user input the search field) on the Product - Category relationship

Possibly you haven't back created the relationship on the relating model you can pass in a function to searchable() and modify the query there i am sure.

I've tried to pass in the $query to the searchable(), but it throw me the error, it didn't accept the $search param

But if you are searching the options.... wouldn't you want the select to be query filtered anyway? Since that's the searchable Just condition the query to not filter when no search is there?

the searchable callback didn't accept the $search param, so I can't get the user input for search there An attempt was made to evaluate a closure for [Filament\Forms\Components\Select], but [$query] was unresolvable.

I mean in the modifyQueryUsing 
modifyQueryUsing: function ($state, $search, $query, $get) {
  if(!empty($search)) {
   $query->where('product_code', $get('product_code')));
  }
  
  return $query;
}
modifyQueryUsing: function ($state, $search, $query, $get) {
  if(!empty($search)) {
   $query->where('product_code', $get('product_code')));
  }
  
  return $query;
}

the modifyQueryUsing accept the $query and $search param. But when i test it, it doesn't accept the $search. like: if ($search) { dd($search); } to check if the search was accepted, but it didn't run.

Just remove the relationship then, and have it as a select with the custom query for the options like you want.

but then I can not perform the ->createOptionForm() / -editOptionForm() on the Select component 🥲

You can define a PrefixAction that does that? It's a bit more work but would work.

Set the create action to be visibleOn('create') and edit one to be visibleOn('edit')

yeah, guess I have to customize this to my need then. Thank you!
