Using file_column and sending correct content type

Rails
1

Hi, I’m using file_column to save images to the file system. To protect
the images, I’m uploading to a non-publicly accessible directory.
Therefore, I’m using a controller method to send the file when
requested:

def get_pic
@fctrial = Fctrial.find(params[:id])
send_file(@fctrial.image, {:disposition => ‘inline’, :type =>
‘image/jpeg’})
end

As you can see, I’m setting the :type to ‘image/jpeg’ so obviously this
is not correct for image/png or image/gif. How do I get to send the
correct content type? Should I save the content type in the database
also? Is there some simpler way?

Thanks,
Mohit.

You could inspect the filename and use that to figure out what type of
file.

Like:

type = ‘image/gif’ if @fctrial[‘image’] =~ /gif$/
(I don’t know if the regex is correct)

Thanks, Greg! That should work… I was just wondering if file_column
stored that information somewhere… cos, obviously, it knows when the
file is uploaded! :smiley:
