f.select不能在rails中工作

Question

我的选择不起作用 这是我的表格 -

  - @anonymous.each do |a|
   =form_for @confession , html: {multipart: true} do |f|
    =f.label :Confess
    =f.text_area :confession , require: true
    =f.label :post_as
    =f.select(:postid,options_for_select([[@confession.amitian.fullname,@confession.amitian.fullname],[a.fullname,a.fullname]]))
    =f.file_field :confessionimage
    =f.submit 'Confess'

这是我的控制器类..

 def index 
  @amitian = Amitian.where(institute: current_amitian.institute) if amitian_signed_in?
  @confessions = Confession.where(amitian_id:    @amitian.ids).order('created_at DESC') if amitian_signed_in?
  @anonymous = Amitian.where(email: 'anonymous@anonymous.com')
  @anonymous.each do |a|
  @debug = a
if params[:postid] == 'Anonymous'
  @confession = a.confessions.build
else
  @confession = current_amitian.confessions.build 
 end
end
end

我的if语句永远不会是真的......为什么？ 上面清楚的f.select语句是this =

f.select（：帖子ID，options_for_select（＆＃39;提供yourname＆＃39;＆＃39;匿名＆＃39）

所以只要用户选择匿名if语句就应该返回true

您需要在创建操作中检查params[:postid]，而不是在索引中。
