问题描述

我正在使用以下内容尝试在表单上设置 PUT 方法，但它仍在发布.我已经参考了文档，看来我做对了.

I am using the following to try and set a PUT method on the form but it is still doing a post. I have referred to the docs and it seems like im doing this right.

form_for @firm, html: {autocomplete: "off"}, url: firm_path, method: :put do |f|

推荐答案

这样做是因为浏览器对 PUT/DELETE 的支持不是很好.您可以在 Rails 指南:

It does this because browsers don't support PUT/DELETE very well. You can read more about this in the Rails Guides:

然而，大多数浏览器不支持除GET"和提交表单时的POST".

However, most browsers don’t support methods other than "GET" and "POST" when it comes to submitting forms.

Rails 通过在 POST 上模拟其他方法来解决这个问题带有一个名为 "_method" 的隐藏输入，它被设置为反映想要的方法.

Rails works around this issue by emulating other methods over POST with a hidden input named "_method", which is set to reflect the desired method.
