here is a similar case but no solution CarrierWave extension_white_list doesn't seem to workCarrierwave provides a function extension_white_list which is supposed to prevent a user from uploading an invalid file. I have uncommented this function but how do I handle this case? I want to catch this error and inform the user that he should change the file.

推荐答案

根据此问题 https://github.com/carrierwaveuploader/carrierwave/issues/1896

解决方案是这样，它对我有用；

The solution is this and it worked for me;

更改:

def extension_white_list
end

收件人:

def extension_whitelist
end

因此他们从白名单单词中删除了下划线.

so they have removed the underscore from whitelist word.
