ruby-on-rails - 使用 Wicked gem 时参数数量错误（1 代表 0）错误

Question

我在最后一步注册用户时收到此错误，用户已注册但我不知道为什么会出现此错误。

private
 def redirect_to_finish_wizard
  redirect_to root_url, notice: "Thanks for signing up."
 end

请任何解决方案

Answer 1

尝试改变你的redirect_to_finish_wizad方法如下：

private

  def redirect_to_finish_wizard(options = nil)
    redirect_to root_path , notice: "Thank you for signing up."
  end

这将解决您的问题。有关方法的更多信息，请参见此处。

Answer 2

gem 似乎再次被修改，该redirect_to_finish_wizard方法接受 2 个参数而不是 1 个。

redirect_to_finish_wizard如果之前的代码中断，请尝试如下更改您的方法：

private

  def redirect_to_finish_wizard(options = nil, params = nil)
    redirect_to root_path , notice: "Thank you for signing up."
  end
