Question

我有一些资源的Active Admin索引页。

ActiveAdmin.register Request do
  index do
    column :created_at
    column :content
    column "Approved", :approved?
    default_actions
  end

  filter :created_at
  filter :content
  filter :approved?
end

问题是它不会为approved?请求生成过滤器（但它会正确生成列）。我认为这是因为approved是一种方法，如果approved_at不是nil，则返回true。在这种情况下如何编写过滤器？

Answer 1

尝试使用范围创建过滤器按钮：

# model/request.rb
scope :approved, where("approved_at IS NOT NULL")

# or...if you have other default values on approved_at column you can try this
scope :approved, where("approved IS NOT", nil)
scope :approved, where("approved IS NOT ?", "")

#app/admin/requests.rb
scope :approved

如何在Active Admin中为方法（而不是字段）编写过滤器？
