导轨。 SmartListing gem 在销毁项目后不刷新表

Question

我有一个包含类别表的页面。我正在使用 SmartListing GEM 对数据进行排序，还为表格中的每个项目添加了一些按钮，包括“删除”按钮。

问题： 表格中的元素被删除后，表格闪烁但不刷新数据，所以我需要重新加载孔页以获取更新的表格。 （顺便说一句，从数据库中删除元素没有问题）

我的文件看起来像 developer example 中的文件。

我的文件：

CategoriesController

                         [:calculate, 'categories.issues_count']

  @category = Category.find(params[:id])

Answer 1

我找到了解决问题的方法。它被简单地解决了 - 只需添加到 destroy 操作行 redirect_to action: 'index', status: 303，所以这个操作应该如下所示：

def destroy
  @category = Category.find(params[:id])
  if @category.issues.empty?
    @category.destroy
    flash[:success] = 'Deleted'
    redirect_to action: 'index', status: 303
  else
    flash[:alert] = 'Category isn\'t empty!'
  end
end
