rails_admin与rails-api冲突

Question

我有一个最近启动的项目,我正在使用mongoid进行数据库和rails_admin来管理它,现在我想要一个api并且我选择了rails-api来做它,但出于某种原因,因为我刚刚添加了rails- api到gem文件,我无法访问管理员,我总是得到这个错误

Devise中的NoMethodError :: SessionsController #new

未定义的方法`[]'为nil:NilClass

这是痕迹

我真的不知道造成这种情况的宝石之间发生了什么,欢迎任何建议或方向;)

Answer 1

我遇到了同样的问题,我发现Warden需要两个在API应用程序中默认不存在的中间件:ActionDispatch :: Session :: CookieStore和ActionDispatch :: Cookies.

因此,可以通过以下方式添加这些中间件:
#config/application.rb
config.middleware.use ActionDispatch::Cookies
config.middleware.use ActionDispatch::Session::CookieStore
