小编Hie*_* Le的帖子

我尝试在Google上搜索,但没有找到任何安装说明.有人可以帮我吗.我使用的是Ubuntu 12.04.谢谢!

mymodel.rb

enum status: { posted: 1, failed: 2, suspended: 3 }

mycontroller.rb

def filter_params
  params.fetch(:mymodel, {}).
  permit(
    :status => []
    )
end

我有类似的参数 mymodel[:status] => ["failed", "suspended"]

如何通过状态获得所有结果是failed和suspended

就像是: Mymodel.where(status: filter_params[:status])

非常感谢!

当一个电话:

@mymodel = Mymodel.new(filter_params)

我收到了这个错误:

'["failed", "suspended"]' is not a valid status

我的情况:

text = "[A] and [B]"
search = ["[A]", "[B]", "[C]", "[D]", "[Aa]"]
replace = ["[B]", "[C]", "[D]", "[E]", "[Bb]"]

我要替换的值text来"[B] and [C]"

我怎样才能做到这一点？非常感谢!
