For an error like this it is better to show the full error trace, but first look at it yourself. 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/cd9zntg2ite57ept288kfa For 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.
