/home/railsu/shenzhenware/releases/1280/app/views/pages/home.html.erb 这个路径下面的文件不存在了？
注意 respond_to 这里的顺序
respond_to do |format|
format.js
format.html
end
像上面这种写法，curl 或爬虫 (对应 :formats=>["*/*;"]) 则会报上述错误...要优先把 format.html 放在前面
另外一种解法 format.all ：
respond_to do |format|
format.all { render :show, formats: [:html]}
end

这样应该就可以了
respond_to do |format|
format.html { render 'some' }
format.all { head(:unauthorized) }
end
#7 楼 @fate +1 #6 楼 @seabornlee 你可以检查一下，是不是没做对，所以重现不了。
解决思路有两种：1）指定请求格式 2）即使请求格式不对，也能响应 第一种，你可以用 before_action 之类的指定 request format(response format 也就对应上了) 第二种，例如我上面的示例~~
不知道其他页面有没有类似问题，你可以自己根据需求进行选择…
respond_to do |format|
format.html
format.js
format.all { render :home, formats: [:html] }
end
describe 'GET home' do
it 'renders html template' do
request.accept = 'text/html'
get :home
expect(response).to render_template :home
expect(response.header['Content-Type']).to include 'text/html'
end
it 'renders js template' do
request.accept = 'application/javascript'
get :home
expect(response).to render_template :home
expect(response.header['Content-Type']).to include 'text/javascript'
end
it 'renders html template for other formats' do
request.accept = "*/*;"
get :home
expect(response).to render_template :home
end
end
