Question

I’m brand new to ruby on rails and trying to run an application developed by others. I downloaded it from SVN it running yesterday, but today when I try to run it the first attempt to access the site’s home page I get the message:

expected …/app/helpers/interface/table_helper.rb to define Interface::tableHelper.

…/lib/active_support/dependencies.rb:452:in ‘load_missing_constant’

This file exists, and properly defines the tableHelper interface. Since I was able to run the program when I was setting it up yesterday, and others can run it without issue, I assume the problem I’m seeing is caused by an incorrectly set up environment rather then bad code somehow.

Can anyone suggest what I might try to figure out why rails can’t seem to detect a properly defined interface?

Answer 1

If you were able to run the program once, perhaps something got screwed up? Have you made any changes to the code?

Alternatively, try stopping and restarting the server.

Also: what’s the application? Maybe we can look at the codebase…
