ruby on rails-创建不提交POST请求的方法

Question

我在rails应用程序中有一个控制器，用户可以通过它创建假日请求，当我填写必要的信息时，它似乎不是在执行POST请求并提交我的表单。我在RailsPanel中的输出如下：rails Panel。由此看来，它就好像在做GET请求，而它肯定应该先做GET，然后再做POST。我相信我的创作方法有些地方搞砸了。任何反馈都将非常感谢！

控制器

  before_filter :admin_user, :only => [:index, :update, :edit, :absence]

原因是，您的holidays/show.html.erb中有一个表单，但holidays/new.html.erb中没有。

根据rails惯例，如果表单是在new.html.erb中提交的，则默认情况下会调用该特定控制器的POST方法。

但是，由于您的文件是show.html.erb，因此必须在form_for中显式定义POST方法。

form_for @holiday , :url => { :action => :create }, :html => { :method => "post"} do |f|
