php - Voyager Page Blocks 无法删除图像

Question

向我的页面添加了标准图像行块。添加了一些图片。并且不能删除最后一张图片。第一次 - 删除图标没有监听器，当点击图标时 - 没有发生任何事情。复制到我的项目的块编辑视图 \resources\views\vendor\voyager\page-blocks\edit-add.blade.php 从 \vendor\tcg\voyager\resources\views\bread\edit-add.blade 复制的侦听器。 php - 删除工作的地方

            $('.form-group').on('click', '.remove-multi-image', deleteHandler('img', true));
            $('.form-group').on('click', '.remove-single-image', deleteHandler('img', false));
            $('.form-group').on('click', '.remove-multi-file', deleteHandler('a', true));
            $('.form-group').on('click', '.remove-single-file', deleteHandler('a', false));

        $('#confirm_delete').on('click', function(){
            $.post('{{ route('voyager.'.$dataType->slug.'.media.remove') }}', params, function (response) {
                if ( response
                    && response.data
                    && response.data.status
                    && response.data.status == 200 ) {

                    toastr.success(response.data.message);
                    $file.parent().fadeOut(300, function() { $(this).remove(); })
                } else {
                    toastr.error("Error removing file.");
                }
            });

            $('#confirm_delete_modal').modal('hide');
        });

修复了小问题。但请求删除图像返回 400 - {"data":{"status":400,"message":"Field does not exist"}}

我认为这是因为页面块在一个 DB 列“数据”中包含所有字段

您对如何解决此问题有任何想法吗？
