Hello,

I’m running into an issue I don’t understand (I’m new to ruby):  
in my “Journey” controller / “course\_detail” action I render the  
following partial (this is call by a Prototype Ajax function):

render :partial =\> ‘courses/course\_detail’, :object =\> @course

in the \_course\_detail.erb file I have:

Distance\*: \<%= course.distance %\>

BUT I tells me “course” doesn’t exist: “undefined local variable or  
method ‘course’”

Please, can someone help me through this one???

Probably the @course object is available in your partial in a variable  
named course\_detail

If that doesn’t work, try your question in the Rails Forum  
[http://www.ruby-forum.com/forum/3](http://www.ruby-forum.com/forum/3) – the ruby-talk list is for general  
Ruby discussion. The Rails forum is all Rails all the time. You’ll get  
a much more authoritative response there.

Sorry I looked at the forum list and I thought this was the more  
accurate. Next time I’ll post those questions in forum 3.

And thanks Mickael, you got it right. Sometimes I really don’t  
understand the naming of ROR.

Thanks for you help!
