[Bug] Unable to use filter of type 'view'

[GiuseppeBenfenati]

I configured in list operation a filter with custom view:

CRUD::filter('path')
    ->label(getTrans('labels.questions'))
    ->type('view')
    ->view('vendor.backpack.crud.filters.path_field')
    ->whenActive(function ($value) {
        CRUD::addClause('pathHasNode', $value);
    });

I received Exception

Undefined array key "view"

View component use 'view' key to include custom view

@include($filter->options['view'])

I think the problem is in the CrudFilter class can't convert view method in options key because 'view' is already a class property

I ovverided view component and used another key

@include($filter->options['customView'])

CRUD::filter('path')
    ->label(getTrans('labels.questions'))
    ->type('view')
    ->customView('vendor.backpack.crud.filters.path_field')
    ->whenActive(function ($value) {
        CRUD::addClause('pathHasNode', $value);
    });

Hey @GiuseppeBenfenati

Sorry for the inconvenience, and thanks for reporting the BUG. I'm escalating the issue for the fix.

@pxpm In my investigation, I found the following:

// works ✅
$this->crud->filter('simple_filter')
    ->type('simple')
    ->whenActive(function () {
        $this->crud->addClause('where', 'checkbox', '1');
    });

// works ✅
$this->crud->addFilter(
    [ // add a "simple" filter called Draft
        'name'  => 'simple_view_filter',
        'label' => 'SimpleView',
        'type'  => 'view',
        'view'  => 'backpack.pro::filters.simple',
    ],
    false, // the simple filter has no values, just the "Draft" label specified above
    function () { // if the filter is active (the GET parameter "draft" exits)
        $this->crud->addClause('where', 'checkbox', '1');
    }
);

// same thing with fluent syntax doesn't work ❌
$this->crud->filter('simple_view_filter')
    ->type('view')
    ->view('backpack.pro::filters.simple')
    ->whenActive(function () {
        $this->crud->addClause('where', 'checkbox', '1');
    });

Hey @GiuseppeBenfenati thanks for the report.

Sorry the filters api is a little bit messy, we will give it some love. 🙏
I've just merged a fix in backpack/crud, I will tag a new version later today that at least will make the fluent behave more similar to the old array syntax.

What I usually do, and I advice anyone to do, is something along this lines:

CRUD::filter('path')->type('path_field')->viewNamespace('vendor.backpack.crud.filters')->whenActive(function ($value) {
        CRUD::addClause('pathHasNode', $value);
    });

After the update, the way you defined should work just fine, but if you want a more future-proof, I would use the one I told you now.

Cheers
