Question

<%= f.time_select :exact,  {ampm: true, :discard_minute=> true} %> # t.time     "exact"

如何在params中传递上述内容？

session[:challenge_exact] = params[:exact].parse_time_select! # got nil error
session[:challenge_exact] = challenge_params[:exact]
session[:challenge_exact] = [params["challenge"]["exact(1i)"], params["challenge"]["exact(2i)"], params["challenge"]["exact(3i)"], params["challenge"]["exact(4i)"], params["challenge"]["exact(5i)"]].join(',')

以上工作都没有。在创建挑战后，我看到exact: nil，即使它已填充在表单中。

它在控制台中的显示方式......

exact: 2000-01-01 02:32:00 UTC>

Answer 1

您可以访问exact参数，例如：

> params[:challenge]["exact(1i)"]
#=> "2017"
> params[:challenge]["exact(2i)"]
#=> "5"
> params[:challenge]["exact(3i)"]
#=> "2"
> params[:challenge]["exact(4i)"]
#=> "08"
> params[:challenge]["exact(5i)"]
#=> "27"

您可以像这样解析时间：

exact_time = "#{params[:challenge]['exact(4i)']}:#{params[:challenge]['exact(5i)']}"
#=> "08:27"
> session[:challenge_exact] = Time.parse(exact_time)
#=> 2017-05-03 08:27:00 +0530

Answer 2

我愿意：

session[:challenge_exact] = components_to_absolute(params[:exact])

def components_to_absolute(components)
  DateTime.new(components['exact(1i)'].to_i,
               components['exact(2i)'].to_i,
               components['exact(3i)'].to_i,
               components['exact(4i)'].to_i,
               components['exact(5i)'].to_i)
end

如何在控制器参数中传递time_select？
