ruby-on-rails – simple_form f.hidden_??field有效,为什么不f.

导读：= simple_form_for @foo do |f| # this works = f.hidden_field :asdf,:value = @some.thing # this works = f.input :asdf,:as = "hidden",:input_html = { :value = @some.thing } # Why doesn't this work,exactly? = f.input :title,:value = @some.thin

= simple_form_for @foo do |f|

  # this works
  = f.hidden_field :asdf,:value => @some.thing

  # this works
  = f.input :asdf,:as => "hidden",:input_html => { :value => @some.thing }

  # Why doesn't this work,exactly?
  = f.input :title,:value => @some.thing

当我查看我的日志时,我看到该值在后一个输入中以空字符串形式出现,但我不清楚为什么会发生这种情况.

解决方法

f.hidden_??field是 ActionView::Helpers::FormHelper,而f.input属于 SimpleForm.

语法类似但有一些差异.
