Hi ,

extension .txt, .xls, .doc but when i am going to upload .pdf extension  
file i gives

```
Validation failed: Content type is not included in the list

```

error.

My model file code is here .

class Model\< ActiveRecord::Base

has\_attachment :content\_type =\>[‘application/pdf’,‘application  
/msword’,‘application/vnd.ms-excel’,‘text/plain’],  
:storage =\> :file\_system,  
:size =\> 0.kilobytes…10000.kilobytes  
validates\_as\_attachment  
end

Is there any issue for attachment\_fu or anything else ?
