在我的模型中:
has_attached_file :uploaded_file,:url => "/policy_documents/get/:id",:path => "/public/policy_documents/:id/:basename.:extension" validates_attachment_size :uploaded_file,:less_than => 10.megabytes validates_attachment_presence :uploaded_file validates_attachment_content_type :uploaded_file,:content_type =>['application/pdf','application/xlsx'],:message => ',Only PDF,EXCEL,WORD or TEXT files are allowed. '
此后,它只能上传PDF文档,而不是excel或word或文本文档.请帮我我失踪的地方
解决方法
我不知道你是否为自己解决了这个问题,但是你想要处理的文档缺少MIME类型,请尝试更改:content_type:
:content_type => ["application/pdf","application/vnd.ms-excel","application/vnd.openxmlformats-officedocument.spreadsheetml.sheet","application/msword","application/vnd.openxmlformats-officedocument.wordprocessingml.document","text/plain"]
或使用自定义验证
validate :correct_content_type,:message => ",WORD or TEXT files are allowed." def correct_content_type acceptable_types = ["application/pdf","text/plain"] acceptable_types.include? uploaded_file.content_type.chomp end
