我的应用程序有一个页面，允许用户通过表单向我发送电子邮件（不会发布我的地址）。它与电子邮件控制器相关联，并且是#new动作，我将其重新路由到'/ contact'。
奇怪的是，如果电子邮件因任何原因没有发送（用户将字段留空或者我输入的数学验证码失败），当控制器再次呈现“新”时，网址变为'/电子邮件。我完全无法理解这一点。一些相关的代码：
#emails_controller.rb
require 'math_captcha'
class EmailsController < ApplicationController
def new
@captcha = MathCaptcha.new
@email = Email.new
end
def create
@captcha = MathCaptcha.decrypt(params[:captcha_secret])
@email = Email.new(params[:email])
unless @captcha.correct?(params[:captcha]) || params[:captcha] == "21261"
flash.now[:error] = "Please make sure you answered the math question correctly."
render :new
else
if @email.save
Contact.contact_message(@email).deliver
flash[:success] = "Your email has sent! I'll try to get back to you shortly."
redirect_to root_path
else
flash.now[:error] = "Please correct the highlighted errors and try again."
render :new
end
end
end
end
和
#routes.rb
resources :users, :posts, :sessions, :emails
#...
match '/contact', to: 'emails#new', as: 'contact'
在我尝试修复它之前添加“as contact”之前，存在同样的问题。有什么想法吗？

答案 0 :(得分：1)
预计会在地址栏中显示“/ email”，因为您刚刚发布到该网址。如果你真的想要显示'/ contact'，你应该设置一个POST路线，如：
获取'/ contact'，以：'电子邮件#new' 发布'/ contact'，以：'发送电子邮件#create'
也许还有另一种更简洁的方法，但这应该有效。
