在查詢字符串中添加參數Rails

Question

我將查詢字符串中的參數添加到new_store_registration並由after_sign_up_path_for方法保留的路徑中。 registrations_controller.rb

def new 
    session[:registration_params] = request.query_parameters 
end 


def after_sign_up_path_for(resource) 
    new_transaction_path(resource, session[:registration_params]) 
end 

我拉着以下PARAMS：

<%= link_to "Sign up", new_store_registration_path(:plan_id => plan.id, :price => plan.price) %> 

申請成功後，應用程序重定向到的意見/ transcation/new.html.erb，它具有plan_id的數據類型，價格參數。

在這一點上我試圖通過new.html.erb內部電子郵件PARAM並保持休息PARAMS有：

<%= hidden_field_tag(:email, params[:email]) %> 
<%= hidden_field_tag(:plan_id, params["plan_id"]) %> 
<%= hidden_field_tag(:amount, params["price"]) %> 

但電子郵件參數是上來了空

Parameters: {"utf8"=>"✓", "authenticity_token"=>"KeS2xK7NIJZwFQvW2kJKupcpURnQweq+yoRgk9AJ1aaOgFIIym4RKadI4jc6vYynMo4vKR4eLmdIynfBG+EusQ==", "email"=>"", "plan_id"=>"bs96", "amount"=>"150.0", "payment_method_nonce"=>"0c22f2fa-e212-0ad3-753b-0d183d02522b"} 

任何想法，爲什麼這不工作???

UPDATE1

我提交申請成功後我得到這個：

看你的更新，似乎存在一個字符您的email參數名稱看起來像a但不是。它可以從

Started GET "/transactions/new.1?ema%E2%80%8C%E2%80%8Bil=example%40gmail.com&plan_id=bs96&price=150.0" for 127.0.0.1 at 2017-08-09 15:24:17 +0300 

仔細檢查，可以看出&重新輸入email你在哪裏設置它。
