第一次表单/模型验证失败后，URL参数丢失

Question

I am using a guid to be used as a parameter during the creation of a new user. The route for this is defined as following:

  match 'add_user/:guid', :to => 'users#new', :as => :add_user, :via => :get 

The problem is that when validation fails (ie. empty first name, etc.), the 'new' method reloads without the appended guid as was the case on the first load.

The form reloads with the validation error and

/users

as the URL. The guid is lost.

Is there a way to preserve the guid between the various requests that occurs as the user input is being validated?

Answer 1

How about making a hidden input with the guid? Or changing action POST path to be the same as GET and passing the guid in the URL again?
