我正在尝试在 rails 上存储一个数组,但在解码时出现错误.我使用 cookies[:test] = Array.new当我试图解码时@test = ActiveSupport::JSON.decode(cookies[:test])我收到一个错误.实现我想要实现的目标的正确方法是什么?
I am trying to store an array on rails an getting error on the decoding. I use cookies[:test] = Array.new And when I am trying to decode @test = ActiveSupport::JSON.decode(cookies[:test]) I am getting an error. Whats the proper way to achieve what I am trying to ?
推荐答案使用 session,而不是 cookies.您不必解码它,rails 会为您处理.以与您相同的方式创建会话:
Use session, not cookies. You don't have to decode it, rails handles that for you. Create the session the same way you already are:
session[:test] = Array.new当你需要它时,像往常一样访问它
and when you need it, access it like normal
session[:test] # => []更多推荐
