Rails 3 returning a HTTP 406 Not Acceptable?
提问by Neil Middleton
I have the following controller code:
我有以下控制器代码：
def create
@admin = Admin.new(params[:admin])
respond_to do |format|
if @admin.save
redirect_to(@admin, :notice => 'Admin was successfully created.')
else
render :action => "new"
end
end
end
def update
@admin = Admin.find(params[:id])
respond_to do |format|
if @admin.update_attributes(params[:admin])
redirect_to(admin_admins_path, :notice => 'Admin was successfully updated.')
else
render :action => "edit"
end
end
end
and the following routes:
以及以下路线：
admin_admins GET /admin/admins(.:format) {:action=>"index", :controller=>"admin/admins"}
admin_admins POST /admin/admins(.:format) {:action=>"create", :controller=>"admin/admins"}
new_admin_admin GET /admin/admins/new(.:format) {:action=>"new", :controller=>"admin/admins"}
edit_admin_admin GET /admin/admins/:id/edit(.:format) {:action=>"edit", :controller=>"admin/admins"}
admin_admin GET /admin/admins/:id(.:format) {:action=>"show", :controller=>"admin/admins"}
admin_admin PUT /admin/admins/:id(.:format) {:action=>"update", :controller=>"admin/admins"}
admin_admin DELETE /admin/admins/:id(.:format) {:action=>"destroy", :controller=>"admin/admins"}
Now, aside from the slightly whacky naming - the redirects always result in a 406 Not acceptable. What could be wrong?
现在，除了有点古怪的命名 - 重定向总是导致 406 不可接受。可能有什么问题？

Remove respond_to do |format|blocks. Because you are not specifying to what format are you responding, e.g. format.html { #your code here }.
Check documentation of respond_tohow to use it properly.
删除respond_to do |format|块。因为您没有指定要响应的格式，例如format.html { #your code here }. 检查response_to 的文档如何正确使用它。

I had a similar error, my controller was only responding to JSON. I needed it to respond to HTML also for the tests to work (which only makes sense):
我有一个类似的错误，我的控制器只响应 JSON。我需要它来响应 HTML 也让测试工作（这才有意义）：
class AdsController < ApplicationController
respond_to :json, :html
I received the error when trying to do: assert_redirected_to ad_url(ad)
我在尝试执行时收到错误：assert_redirected_to ad_url(ad)

I started having this issue after a deploy in production, even tough everything was working fine in development.
在生产中部署后，我开始遇到这个问题，即使在开发中一切都很好。
After some 15 minutes of wasted time, I finally found out that I had forgotten to commit some of the view files (like index.html.erb).
经过大约 15 分钟的浪费时间，我终于发现我忘记提交一些视图文件（如 index.html.erb）。
Using tail -f log/production.logon the server revealed: FATAL -- : ActionController::UnknownFormat (SomeController#index is missing a template for this request format and variant.
tail -f log/production.log在服务器上使用显示：FATAL -- : ActionController::UnknownFormat (SomeController#index is missing a template for this request format and variant.
In development the error didn't happen because, obviously, the view file was present.
在开发中，错误没有发生，因为显然存在视图文件。
