ruby-on-rails – PUT方法form_for

我正在使用以下内容来尝试在表单上设置一个PUT方法,但它仍然在做一个帖子.我已经提到了这个文件,而且似乎这样做是正确的.

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

解决方法

这样做是因为浏览器不支持PUT / DELETE.您可以在 Rails Guides中阅读更多信息：

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

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.
