突然之间，我的Rails应用上的所有redirect_to次调用都返回了此wrong number of arguments (0 for 1)错误。我无法确定原因。
即使是简单的电话，如
def show
redirect_to root_path
end
# routes
root to: "home#index"
......在回溯中没有任何迹象，至少我可以指出。
我已经尝试过了，基于此处回答的其他问题：
在所有其他答案中，问题似乎是古老的宝石或拼写错误，但在我的情况下，所有这些都只是停止了工作，即使那些已经好几个月并且未受影响的那些。
跟踪从应用程序的任何位置始终完全相同：

通过这个版本的Rails源代码，这是给出麻烦的方法：
def redirect_to(options = {}, response_status = {}) #:doc:
raise ActionControllerError.new("Cannot redirect to nil!") unless options
raise ActionControllerError.new("Cannot redirect to a parameter hash!") if options.is_a?(ActionController::Parameters)
raise AbstractController::DoubleRenderError if response_body
self.status = _extract_redirect_to_status(options, response_status)
self.location = _compute_redirect_to_location(request, options)
self.response_body = "<html><body>You are being <a href=\"#{ERB::Util.unwrapped_html_escape(location)}\">redirected</a>.</body></html>"
end
根据我的有限知识，我有三个嫌疑人：
location var。但是如何通过更多细节解决或调试此问题？
编辑：从backtrace添加redirect_to行 在这种特殊情况下给出错误的问题是
if @ad.save
UserMailer.admin_event_email('create_ad', @ad).deliver_later
redirect_to ad_created_path, success: I18n.t('The ad is poster and a moderator will aprove it shortly')
end
但它总是发生在redirect_to行。
答案 0 :(得分：0)
更改行
redirect_to ad_created_path, success: I18n.t('The ad is poster and a moderator will aprove it shortly')
为：
redirect_to ad_created_path, :flash => { success: I18n.t('The ad is poster and a moderator will aprove it shortly') }
修改：
将turbo-links更新为verison 2.5.3
gem 'turbolinks', '~> 2.5.3'
编辑2：
在这一行设置一个断点：
=> 76: byebug
=> 77: self.response_body = "<html><body>You are being <a href=\"#{ERB::Util.unwrapped_html_escape(location)}\">redirected</a>.</body></html>"
"<html><body>You are being <a href=\"#{ERB::Util.unwrapped_html_escape(location)}\">redirected</a>.</body></html>"的结果是什么？
答案 1 :(得分：0)
所以，经过长时间的工作，我发现至少部分罪魁祸首：包括ApplicationHelper 进入控制器。
在包含ApplicationHelper的所有控制器中，都会发生此错误。现在，这就是我所做的：
view_context.my_helper 现在，我将尝试找到导致问题的帮助器，并在我找到时更新此答案。
