Ruby on Rails link_to With put Method
提问by maksim
I'm new to Rails, and I'm trying to use the link_to helper to create a link that issues a PUT request instead of a GET request. Specifically, I'm trying to create a link that activates a user's account in my app from the admin's panel. I'm using Rails 3.0.5.
我是 Rails 新手，我正在尝试使用 link_to 助手创建一个链接，该链接发出 PUT 请求而不是 GET 请求。具体来说，我正在尝试创建一个链接，用于从管理面板激活我的应用程序中的用户帐户。我正在使用 Rails 3.0.5。
My routes.rb file has:
我的 routes.rb 文件有：
match '/admin/users/:id/activate' => 'admin#activate_user',
:action => :activate_user, :via => :put
My view has:
我的观点有：
link_to 'Activate', :action => :activate_user, :id => user.id, :method => :put
However this generates the URL (for example) /admin/users/7/activate?method=putwith the source code <a href="/admin/users/7/activate?method=put">Activate</a>.
但是，这会生成/admin/users/7/activate?method=put带有源代码的 URL（例如）<a href="/admin/users/7/activate?method=put">Activate</a>。
I'd like to generate, instead, <a href = "/admin/users/7/activate" data-method="put">Activate</a>
我想生成，而不是， <a href = "/admin/users/7/activate" data-method="put">Activate</a>
I realize I could use button_to, but I've been wrestling with this issue for a while and I'm confused why I'm seeing this behavior, when other tutorials say that what I'm doing should be valid. How can I go about creating a link_to helper with the behavior I want?
我意识到我可以使用 button_to，但我一直在努力解决这个问题，我很困惑为什么我会看到这种行为，而其他教程说我正在做的事情应该是有效的。我如何着手创建一个具有我想要的行为的 link_to 助手？

Updated- The link_tohelper will do a GET unless a method is specified.
更新-link_to除非指定了方法，否则帮助程序将执行 GET。
Its better specifying the exact request type, instead of matchin your routes file. How about replacing matchby putin routes as :
最好指定确切的请求类型，而不是match在您的路由文件中。如何更换match通过put在路线为：
put '/admin/users/:id/activate' => 'admins#activate_user', :as => 'activate_user'
link_to 'Activate', activate_user_path(user.id), method: :put
The activate_usermethod should reside in adminscontroller.
The docshas more info on link_tohelper.
该activate_user方法应驻留在admins控制器中。该文档有更多信息link_to的帮手。

link_tothinks that :method => :putis part of the path hash. You have to tell it otherwise. Wrap your path in brackets.
link_to认为这:method => :put是路径哈希的一部分。否则你必须告诉它。将您的路径括在括号中。
link_to 'Activate', {:action => :activate_user, :id => user.id}, :method => :put
Now link_towill recognize :method => :putas an option, not part of the link's path.
现在link_to将识别:method => :put为一个选项，而不是链接路径的一部分。
As a side note, you should try to use route helpers instead of path hashes whenever possible. Keeps things nice and tidy, and avoids nit-picky situations like this.
作为旁注，您应该尽可能尝试使用路由助手而不是路径哈希。保持事物整洁，并避免像这样挑剔的情况。
