ruby-on-rails – 在发布包含多个文件字段的表单时从nginx获取40

问题是：在发布此表单时,它会加载.我检查了nginx的错误日志,没有找到任何东西.在检查访问日志时,我在超时后获得了该请求的400状态.

我通过禁用文件字段进行了检查.如果以该形式,一个文件字段处于活动状态,则它可以正常工作.但是激活了多个文件字段,发生了这样的错误.

000.11.221.162 - - [19/Aug/2016:11:41:16 +0000] "POST /categories HTTP/1.1" 400 0 "http://someapp.com/categories/new" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML,like Gecko) Chrome/51.0.2704.106 Safari/537.36"

有没有人遇到过这种问题.任何建议都会有所帮助.
