How to validate file content type to pdf, word, excel, and plain text for paperclip?

Question

In my model:

 has_attached_file :uploaded_file,  
                      :url => \"/policy_documents/get/:id\",  
                      :path => \"/public/p

I don't know if you have solved this for yourself but you are missing MIME types for the documents you want to handle try changing :content_type to:

:content_type => ["application/pdf","application/vnd.ms-excel",     
             "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",
             "application/msword", 
             "application/vnd.openxmlformats-officedocument.wordprocessingml.document", 
             "text/plain"]

Or use a custom validation

validate :correct_content_type, :message => ", Only PDF, EXCEL, WORD or TEXT files are allowed."


def correct_content_type 
  acceptable_types = ["application/pdf","application/vnd.ms-excel",     
             "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",
             "application/msword", 
             "application/vnd.openxmlformats-officedocument.wordprocessingml.document", 
             "text/plain"]
  acceptable_types.include? uploaded_file.content_type.chomp
end
