ActionView::TemplateError

Hi,

I have a strange problem that only occurs on the production server.
I’ve been banging my head for hours trying to figure it out with no
success. Below is a copy of the error from the production log.

ActionView::TemplateError (Expected /www/rails_apps/scanlan/current/
public/…/config/…/app/models/image.rb to define Image) on line #6 of
app/views/admin/design/_record.rhtml:

record} %>

Rendering /www/rails_apps/scanlan/current/public/…/config/…/public/
500.html (500 Internal Server Error)

Image.rb does define the Image model and when running script/server on
my local box it works no problems at all. Feedback is greatly
appreciated.

Thanks in advance,
Johnny.

I still havn’t solved this :frowning:

Any help greatly appreciated!

The file needs to be app/models/image.rb (note the lowercase name)
and define the class Image (capitalized class name constant).

If your local server’s filesystem is case-insensitive, app/models/
Image.rb and app/models/image.rb are effectively the same as APP/
mOdEls/iMAge.Rb. I suspect that your production server isn’t so
lenient with filenames.
