I am using image_tag to load an image that I''ve saved to the database
(using attachment_fu if you''re curious but that''s probably not
relevant here):
VIEW
<%= image_tag ''/photo/get_image/5'' %>
CONTROLLER
def get_image
@photo=Photo.find(params[:id])
send_data(DbFile.find(@photo.db_file_id).data,
:type => @photo.content_type,
:file_name =>
@photo.filename,
:disposition => ''inline'')
end
The images I''m saving are less than 100kb and easily handled by my
mysql column of db_file.data which is declared MEDIUMBLOB.
My problem is that the view works perfectly in production but not at
all in development -- in development I just get a broken image graphic
with a box and a red x.
Any ideas on how to troubleshoot this? Since it doesn''t seem to be my
code (it works fine in production) I''m at a loss on how to figure this
out.

i guess that''s the point in that the browser is not displaying the image -- it is just displaying the error gif, ie, a box with a red x in it indicating that i can''t load the image.

Just tried something else -- Changed disposition to "attachment" and used Firefox to successfully download the file. When I tried to open the file (in GIMP) I received these error messages: -- Premature end of JPEG file -- Invalid JPEG file structure: missing SOS marker So, I guess attachment_fu is not saving the files properly to my db_file table...

Yes -- seems like attachment_fu or mysql (?) might be truncating. Weird though as the file size is not very large -- just 10kb. In my experience, truncation occurs because you are handling large files...
