I''m walking through an example in the "Head First Rails" book, but, instead doing the examples using Rails3.0.0.rc. But, I''m getting this error when browsing for example: http://localhost:3000/advs/1 undefined method `eq'' for nil:NilClass Provided that my advs_controller.rb is as follows: http://pastie.org/private/cd9zntg2ite57ept288kfa Any ideas why I''m getting that and a workaround for that?

Somewhere there you will usually find a reference to a line of your code. Look carefully at that line and the error and try and work out the problem yourself. The error is saying that you are trying to call a method on an object that is nil. A common cause of this is using the result of a find operation without checking that it did in fact find a record. If you still cannot see the problem then post the error trace and the code around the error.> > Provided that my advs_controller.rb is as follows: > > http://pastie.org/private/cd9zntg2ite57ept288kfaFor only a few lines of code it is better in my opinion to put it inline rather than a pastie. Particularly consider those who may find the thread in months and years yet to come, hoping for enlightenment, only to find that the pastie has disappeared.

Thanks for your replies. The issue was as follows: As I mentioned, I''m walking through an example in "Head First Rails". I have used the book''s version of "development.sqlite3" that contains some data. I used the name "advs" to create my application, and the table name in the database version I used happen to have the name "ads". So, I just changed the name of the table to "advs" and it worked.
