morphTo relationship manager: list table columns specific for the morphed model?

[wivaku]

I have a one-to-many polymorphic relationship: e.g. a Comment for either a Post or a Video.

For my Comment model I have method $comment->commentable() that returns either a Post or a Video.

For my Filament CommentResource I created a relationship manager CommentableRelationManager.

But how do define the table columns so that they show either the columns relevant for the Post or the ones relevant for the Video?

I could not find it in the documentation.

Updated: my request may have been confusing. I want to define the table for my CommentableRelationManager. So, when I open a comment in my CommentResource, I see the related object that the comment was for: either a Post (with e.g. a textarea field) or a Video (with e.g. a dimensions field). How do I define the form/table in that CommentableRelationManager? Can it be used by both Post and Video?

I have the same question

Looks line this is not documented, but the following does the trick (example from my code):
TextColumn::make('commentable.full_name') ->label('User') ->searchable(),

Seems you missed it in the docs

But if video contains the attribute "views" and post contains the attribute "likes", how do you conditionally can show the attribute in same column?

Hi buddy, I have the same problem and I found a workaround

You can create a method on morph model (Comment), who will deliver the attribute conditionally. You need to setup this method as attribute.

Edit:

You can also do it this way:

Tables\Columns\TextColumn::make('cpf_cnpj')
                    ->getStateUsing(fn($record) => $record->isPeople() ? $record->customerable->cpf : $record->customerable->cnpj)

This is indeed a useful suggestion, and indeed a workaround.
But hoping there's a way to do this not on the field level, but on the full table/form level. A la:

// CommentableRelationManager

if(...) { // is there a way to determine the Model for that specific Commentable?
  return $table->[...Post...] 
} else {
  return $table->[...Video...] 
}

 Tables\Columns\TextColumn::make('licenable')->formatStateUsing(function ($record) {
                    return match ($record->licenable_type) {
                        SmmPanel::class => $record->licenable->name,
                        // todo
                    };
                }),

I stumbled upon this discussion because I had the same challenge. In the end I solved it like this:

My scenario: Several models use tags. I want a tag edit page to show all models this tag is connected to. In order for this to work, you need a TagTaggable pivot model.

My TaggableRelationManager attached to the TagResource:

class TaggablesRelationManager extends RelationManager
{
    protected static string $relationship = 'taggables';

    public function table(Table $table): Table
    {
        return $table
            ->recordTitleAttribute('taggable.name')
            ->columns([
                Tables\Columns\TextColumn::make('taggable.name')
                    ->label(lcl('Name'))
                    ->sortable()
                    ->searchable()
                    ->toggleable(),
                Tables\Columns\TextColumn::make('taggable_type')
                    ->label(lcl('Type'))
                    ->sortable()
                    ->searchable()
                    ->toggleable()
                    ->getStateUsing(fn ($record) => $record->taggable::getPluralModelLabel()),
            ])
            ->filters([
                Tables\Filters\SelectFilter::make('taggable_type')
                    ->label(lcl('Type'))
                    ->options(collect([
                        User::class,
                        UserGroup::class,
                        // ...
                    ])->mapWithKeys(fn ($class) => [
                        $class => $class::getPluralModelLabel(),
                    ])->toArray()),
            ])
            ->recordUrl(fn ($record) => route('filament.admin.resources.'.$record->taggable->getTable().'.edit', ['record' => $record->taggable->uuid]));
    }
}
