我什至不知道从哪里开始......整天都在努力弄清楚。谷歌上没有相关内容。我以前很好，整个网站都无法使用。我去的任何页面都会抛出错误“无法将不允许的参数转换为散列”

gem 向我展示了更好的错误:

覆盖以防止#cause 在重新加注期间重置。

      attr_reader :cause
   def initialize(template)
        super($!.message)
        set_backtrace($!.backtrace)
    @cause = $!
    @template, @sub_templates = template, nil
  end

当天早些时候，我已经升级到 Rails 5，升级方式与其他 Rails 应用完全相同，完全没有问题——它们都或多或少地使用了相同的 gem。我可能遗漏了一些东西，但我什至找不到导致这种情况的丝毫线索。任何帮助都会很棒!谢谢!如果您需要任何其他信息，请告诉我。

重申一下 - 这不是特定于页面的，而是贯穿始终的。通常我可以跟随 Controller 等解决问题，但我完全迷失了这一点。

最佳答案

在 Rails 5.1 中，如果您想将 params 对象转换为散列，您似乎必须允许访问参数。

AFAIK 有两种解决方案:

1) 在您的 Controller 中执行此操作:

form = Form.new(params[:form].permit!)

2) 将此添加到您的 config/application.rb 以禁用 rails 中的强参数(通常不建议):

config.action_controller.permit_all_parameters = true

关于ruby-on-rails - 无法将不允许的参数转换为散列 - Ruby on Rails 应用程序错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/43551676/
