ActionView::Template::Error (Devise could not find the

我不知道该怎么办
请帮帮我.
解决方法
在ApplicationController中定义renderer_with_signed_in_user类方法.
class ApplicationController < ActionController::Base
...
def self.renderer_with_signed_in_user(user)
ActionController::Renderer::RACK_KEY_TRANSLATION['warden'] ||= 'warden'
proxy = Warden::Proxy.new({},Warden::Manager.new({})).tap { |i|
i.set_user(user,scope: :user,store: false,run_callbacks: false)
}
renderer.new('warden' => proxy)
end
...
end
然后你可以从Rails应用程序的其他部分渲染,如下所示：
renderer = ApplicationController.renderer_with_signed_in_user(user)
renderer.render template: 'notifications/show',layout: false,locals: { foo: 'bar' }
