Hi

I wish to upload a file not from the view but from the controller  
itself.  
I have the file’s path and mimetype and size.  
I would like to know How it can be done directly from the controller

Thanks in Advance

filepath = File.open(“File\_path”,“r”)  
File.open(path\_where\_u\_want\_to\_upload, “wb”) { |f|  
f.write(filepath.read) }

I always prefer to actually generate an uploader object just as it  
would come from the view itself.

# Mock method to simulate an actual uploaded file

def mock\_uploader(path, type = ‘application/octet-stream’)  
uploader = ActionController::UploadedStringIO.new  
uploader.original\_path = path  
uploader.content\_type = type  
def uploader.read  
File.read(original\_path)  
end  
def uploader.size  
File.stat(original\_path).size  
end  
uploader  
end

Best regards
