Add custom query to a filter

Tables\Filters\SelectFilter::make('causer_id')
    ->query(function (Builder $query, array $data): Builder {
        return $query->where('id', 1);
    })

Tables\Filters\SelectFilter::make('causer_id')
    ->query(function (Builder $query, array $data): Builder {
        return $query->where('id', 1);
    })

When I set a filter like in the example above my table always filtered and showed only one record with ID 1. I didn't apply the filter and the query string is empty. I want to add a custom query to a filter. How to achieve this?

Solution:

query exists for the other filters like Filter and TernaryFilter. With SelectFilter, the query is handled internally for you so it acts a little differently.

What are you trying to accomplish? If you just need to filter one option, then use a normal Filter and not a Select Filter. A SelectFilter should be used for multiple options. So if you just want to filter where causer_id == 1, then you could do:

Filter::make('causer_id')
    ->query(fn (Builder $query): Builder => $query->where('causer_id', 1))

Filter::make('causer_id')
    ->query(fn (Builder $query): Builder => $query->where('causer_id', 1))

This is just a simple example. I have a more complex logic but I want to show that $query->where('causer_id', 1) always applies to a whole table

Ok…so does using Filter::make()… work for you?

Yes, it works. But I'm not sure for what purpose ->query() exists. Am I not using it right?
