проблема с дружелюбным переадресацией в рельсах

Question

Это своего рода последующее наблюдение за этим trouble with email with one click.

У меня проблемы с дружеской пересылкой. См. Мой код ниже и мой сайт http://fast-reaches-9399.herokuapp.com/. Я не уверен, почему он не работает. Когда я печатаю что-то в текстовое поле и нажмите кнопку отправить, он успешно посылает мне электронную почту, но я получаю

The page you were looking for doesn't exist. 

You may have mistyped the address or the page may have moved. 

URL, это происходит от является http://fast-reaches-9399.herokuapp.com/application_controller/email.

Что можно сделать, чтобы исправить это?

---

application_controller.rb

class ApplicationController < ActionController::Base 
    protect_from_forgery 

    before_filter :store_location 

    def email 
    UserMailer.idea_bar(params[:message]).deliver 
    redirect_back 
    end 

    def redirect_back 
    redirect_to(session[:return_to]) 
    session.delete(:return_to) 
    end 

    def store_location 
    session[:return_to] = request.url 
    end 
end

Я также возникли проблемы с наличием у пользователя есть возможность поставить свою электронную почту в text_field и использования это в: reply_to. Я получаю ошибку We're sorry, but something went wrong. Вот мой код.

application_controller.rb

def email 
    UserMailer.idea_bar(params[:message, :email]).deliver 
    redirect_back 
end 

user_mailer.rb

class UserMailer < ActionMailer::Base 
    default from: "anonymous@collegeanswers.com", to: "azerner3@gmail.com", subject: "collegeanswers" 

    def idea_bar(message, email) 
    mail(:body => message, :reply_to => email) 
    end 
end 

application.html.erb

<div class="idea_bar"> 
      <div class="left_idea_bar"> 
       <p>Ideas, comments, questions, suggestions? Help us help you!</p> 
       <%= form_tag("/application_controller/email", :method => "post", :id => "idea_bar_form") do %> 
        <%= text_area_tag('message', nil, :size => "60x4", :id => "message", :name => "message") %> <br /> 
        <%= label_tag(:email, "• include your email if you want a response:") %> 
        <%= text_field_tag(:email, nil, :id => "email", :size => "36", :name => "email") %> 
      </div> 
        <button id="submit" type="submit" form="idea_bar_form"><span id="big_submit">Send</span> 
        <span id="small_submit"><br />&#8226 one click<br />&#8226 anonymous</span></button>

Answer 1

Вы сохраняете местоположение внутри сеанса по каждому запросу, поэтому, когда вы перенаправляетесь обратно в действие электронной почты, пользователь перенаправляется обратно на действие электронной почты, но через GET на этот раз. Прекратите сохранение местоположения для действия электронной почты, и все будет работать.

- EDIT: о reply_to -

Внутри вашего application_controller.rb, действие электронной почты должен выглядеть следующим образом:

def email 
    UserMailer.idea_bar(params[:message], params[:email]).deliver 
    redirect_back 
end
