问题描述
所以，我正在从一个新的rails-api项目开始一个API。
我想使用Devise进行所有身份验证。我已经从我最近的谷歌搜索会议中学到了很多。我有一个工作的SessionsController，但是我注意到RegisterController，我当然错过了关于Rails-API + Devise的二重奏。
So, I'm starting an API from a new rails-api project.I would like to use Devise for all the authentication stuff. I already learned a lot from my recent googling-sessions. I have a working SessionsController, however I noticed with the RegisterController that I certainly missed something about the duo Rails-API+Devise.
我仍然收到以下错误： ＃
I still get the following error :
NameError (undefined local variable or method 'flash' for # <RegistrationsController:0x007ff6022b44b8>)`
从纯API的角度来看，我应该继续使用Devise Flash消息，因为我不想渲染视图？根据我将渲染JSON的原则，我没有包含 ActionDispatch :: Flash 。那么有没有办法妥善处理这种情况？
From a pure API perspective should I keep working with Devise flash messages since I don't want to render views? I didn't included ActionDispatch::Flash based on the principe that I'll just render JSON. So, is there a way to properly deal with that case?
谢谢。
推荐答案
我宁愿建议在json中发送消息，而不是发送flash [：messages]。如果你没有处理视图，那么去查看json，不需要flash。
I would rather suggest to send messages in json instead of having flash[:messages]. If you are not dealing with views then go for json, flash is not required.
这样的东西：
render :json => {:message => "message", :data => data}
