这是我得到的错误...
This is the error I got...
1 error prohibited this xyz from being saved:
Avatar content type is invalid
推荐答案
这适用于任何类型的文件
This will work for any type of the file
validates_attachment_content_type :avatar, :content_type => /.*/
您还可以使用命令发现文件的确切内容类型
You can also discover exact content type of the file with command
file -i path/to/file # or
file --mime-type path/to/file
我运行了 MP3 文件,它返回了
I have run in on MP3 file and it returned
audio/mpeg
因此,如果您只想验证某些内容类型,您可以将audio/mpeg"添加到列表中
So if you want to validate only some set of content types you can add 'audio/mpeg' to the list
validates_attachment_content_type :avatar, :content_type => [ ..., 'audio/mpeg', ...]
