Load issues with engines 1.0.5 - also some path problems

Rails Engines Development
1

Just upgraded to 1.0.5 from 1.0.2 on my production app. Runs fine here
in development mode on my test boxes but when I push it to the
production server I’m getting an 500 error and the log is telling me
this…

Note that my root directory for the app is
/home/httpd/vhosts/genselect.com/httpdocs … which is a symlink to
/home/httpd/vhosts/genselect.com/rails/public

This path is generated in the method ‘copy_engine_files’
(engines/lib/engines.rb) by:

File.expand_path(File.join(RAILS_ROOT, “public”,
Engines.config(:public_dir)))

… which indicates that your RAILS_ROOT is neither of the paths you
specify at this point… puzzling. Any ideas? I suspect it might be a
result of the File.expand_path(). You might play around with calling
this line of code in a script/console session to see what different
results you get.

You’ve probably typed ‘login_system’ instead of ‘login_engine’ :slight_smile: The
RAILS_ROOT issue is very weird though.

I’ll take a look at the path thing. And no, I’ve not typed it
incorrectly as I’m not using the login_engine. I’m using my own login
system at the moment…

Also, the same code works beautifully if I run via webrick on the
production server in production mode - so it’s something to do with
Apache/FCGI configuration that’s screwing things up.
