I am currently entrenched in ActiveRecord – trying to learn it and implement it on a project. There seems to be a lot of practical documentation and examples missing on the net (or my search skills have severely diminished).

Anyway – I hope to put together a few postings on my learnings to try and save you some time should you run into the same problems.

Here’s the first:

“Could not perform SlicedFindAll for ClassName”

I’m trying to create a new user, and attach a company that was populated into a select list.

This is the line that caused the error:

Company.Find( lbCompany.SelectedValue );

Apparently, despite the fact that the Expression function I’m calling takes an Object as for the value, it won’t convert it to the appropriate type. This caused me many headaches trying to search through 285MB of log files (created just from the init and few calls I make to log4net before this point). I was unable to get the same result in my unit tests because I was passing in an actualy Int32.

So – convert the value to an Int32 (assuming your primary key is an Int32), and you should be fine.

Company.Find(Convert.ToInt32(lbCompany.SelectedValue));

Good luck.

Shendy.
