Working With Rails

You get an ActiveRecord::RecordNotFound exception when you try to find a row in the database that doesn’t exist. At some point you’re executing a #find call of some kind, with, presumably, an invalid ID.

It’s possible that the problem is relatively simple and you simply need to check the IDs that your controllers receive before trying to find them. It’s also possible that some of your ActiveRecord objects are trying to load associated objects which don’t exist; either because you have invalid data loaded from fixtures, or because something deleted a row leaving a dangling reference, or something else entirely.

To be honest, the easiest and best way to track down problems like this is to make sure you comprehensively test your controllers as you’re writing them.

Also, on an unrelated note, your example code will be easier to read in these posts if you wrap it in <pre> tags. Like so:

<pre>
class Movie < ActiveRecord::Base
  ...
end
...
</pre>

I do have the feeling that the answer is probably something very simple. I’m still trying to get my arms around how to properly write and perform and interpret the results of tests, and I suppose now is the best time to learn. :-)

Going to check and make sure that I have the proper rows in db’s as well. And thanks for the tip on properly formatting my example code. Cracking open my simply rails 2 book again :-)

Thanks for the help
