I'm having trouble serving images which I have saved as db_files with
attachment_fu. I use this code to serve the images:
Controller --
class PhotoController < ApplicationController
def image
@photo=Photo.find(params[:id])
send_data(DbFile.find(@photo.db_file_id).data,
:type => @photo.content_type,
:filename => @photo.filename,
:disposition => 'inline')
end
end
View --
<%=image_tag(url_for(:controller=>'photo', :action=>'image',
:id=>@photo))%>
On the web page, I just get a box with a red X in it where the image
should be. This occurs only on my development machine (windows XP) but
not on my production machine (linux). On my production machine all
works perfectly.
To debug, I switched :disposition=>'inline' to
:disposition=>'attachment', downloaded the file, and opened with GIMP.
GIMP reports these errors:
"Premature end of JPEG file" and
"Invalid JPEG file structure -- missing SOS marker".
Does anyone have any ideas?
I am using ImageScience as my processor.
(BTW, I have already implemented the attachment_fu_patch which fixes
various windows/attachment_fu problems described here --
