Modify SelectFilter query based on another SelectFilters value (Dependent Filters)

I have these 2 filters ( in my app:

                SelectFilter::make('game')
                    ->relationship('games', 'name'),

                SelectFilter::make('server')
                    ->relationship(
                        name: 'servers',
                        titleAttribute: 'abbrevation',
                        modifyQueryUsing: function (Builder $query) {
                            return $query->orderBy('servers.game', 'asc')->orderBy('servers.id', 'asc');
                        }
                    ),

                SelectFilter::make('game')
                    ->relationship('games', 'name'),

                SelectFilter::make('server')
                    ->relationship(
                        name: 'servers',
                        titleAttribute: 'abbrevation',
                        modifyQueryUsing: function (Builder $query) {
                            return $query->orderBy('servers.game', 'asc')->orderBy('servers.id', 'asc');
                        }
                    ),

I want to make the 2nd filter so, that it only queries the servers, which are selected by the first selectFilter, or otherwise show all. I can do that with custom filters, but is there some out of the box solution for this?

Yes to use this I need custom filters with queries that I need to write myself, that was the point of the question, if I can avoid it

Matt Jenkins•8mo ago

I'm after the same thing, did you ever find a solution to this?

I did it with custom filters, no easy way to do it You need to do a Filter, and make a form for it with multiple Select fields

Filter::make('accounts')
                    ->form([
                        Grid::make(2)
                            ->schema([
                                Select::make('game')
                                    ->relationship('games', 'name')
                                    ->live()
                                    ->placeholder('All'),

                                Select::make('server')
                                    ->relationship(
                                        name: 'servers',
                                        titleAttribute: 'name',
                                        modifyQueryUsing: function (Builder $query, Get $get) {
                                            if ($get('game') != null) {
                                                return $query->where('servers.game', $get('game'))->orderBy('servers.game', 'asc')->orderBy('servers.id', 'asc');
                                            } else {
                                                return $query->orderBy('servers.game', 'asc')->orderBy('servers.id', 'asc');
                                            };
                                        }
                                    )
                                    ->live()
                                    ->placeholder('All'),
]),
                    ])

Filter::make('accounts')
                    ->form([
                        Grid::make(2)
                            ->schema([
                                Select::make('game')
                                    ->relationship('games', 'name')
                                    ->live()
                                    ->placeholder('All'),

                                Select::make('server')
                                    ->relationship(
                                        name: 'servers',
                                        titleAttribute: 'name',
                                        modifyQueryUsing: function (Builder $query, Get $get) {
                                            if ($get('game') != null) {
                                                return $query->where('servers.game', $get('game'))->orderBy('servers.game', 'asc')->orderBy('servers.id', 'asc');
                                            } else {
                                                return $query->orderBy('servers.game', 'asc')->orderBy('servers.id', 'asc');
                                            };
                                        }
                                    )
                                    ->live()
                                    ->placeholder('All'),
]),
                    ])

Then a query for it

 ->query(function (Builder $query, array $data): Builder {
                        return $query
                            ->when(
                                $data['game'],
                                fn (Builder $query, $game) => $query->whereHas(
                                    'games',
                                    fn (Builder $query) => $query->where('games.id', $game)
                                )
                            )
                            ->when(
                                $data['server'],
                                fn (Builder $query, $server) => $query->whereHas(
                                    'servers',
                                    fn (Builder $query) => $query->where('servers.id', $server)
                                )
                            );
                    })

 ->query(function (Builder $query, array $data): Builder {
                        return $query
                            ->when(
                                $data['game'],
                                fn (Builder $query, $game) => $query->whereHas(
                                    'games',
                                    fn (Builder $query) => $query->where('games.id', $game)
                                )
                            )
                            ->when(
                                $data['server'],
                                fn (Builder $query, $server) => $query->whereHas(
                                    'servers',
                                    fn (Builder $query) => $query->where('servers.id', $server)
                                )
                            );
                    })

Then you need an indicator for it

->indicateUsing(function (array $data): array {
                        $indicators = [];
                        if ($data['game'] ?? null) {
                            $indicators['game'] = 'Game: ' . Game::find($data['game'])->displayname;
                        };
                        if ($data['server'] ?? null) {
                            $indicators['server'] = 'Server: ' . Server::find($data['server'])->abbrevation;
                        };
                        return $indicators;
                    }),

->indicateUsing(function (array $data): array {
                        $indicators = [];
                        if ($data['game'] ?? null) {
                            $indicators['game'] = 'Game: ' . Game::find($data['game'])->displayname;
                        };
                        if ($data['server'] ?? null) {
                            $indicators['server'] = 'Server: ' . Server::find($data['server'])->abbrevation;
                        };
                        return $indicators;
                    }),

Fantastic, I'd actually gone down that road before but completely forgot.
