在查询字符串中添加参数，Rails

Question

我正在将查询字符串中的参数添加到 new_store_registration 并由 after_sign_up_path_for 方法保存的路径。 注册控制器.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

我正在提取以下参数：

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

注册后，应用会重定向到 views/transcation/new.html.erb，其中包含 plan_id、价格参数。

此时我正在尝试在 new.html.erb 中传递电子邮件参数并保留其余参数：

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

但是电子邮件参数是空的

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

知道为什么这不起作用？？？

提交注册后，我得到了这个：

查看您的更新，您的 email 参数名称中似乎有一个字符，看起来像 a 但不是。可见

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

仔细检查并重新输入email 您设置它的位置。
