Hi,

I was wondering if anybody knew what ’ expected, got Fixnum’  
means? My code looks like the following:

begin  
anevent = Event.new  
anevent.title = params[“event”][“title”]  
anevent = session[:user\_id]  
com = Community.find(params[:id])  
com.events \<\< anevent  
rescue Exception =\> exc  
…  
end

But I get an exception.

Thanks a lot.

> ```

\<…\>

> ```
> anevent = session[:user_id]
> 
> ```

Is this what you really want?

expected, got Fixnum: that means that you try to assign a  
fixnum  
(an integer…) into something else, and it is not possible to cast the  
fixnum into that something (okay, I’m not sure this helps, I find the  
error  
quite clear if you read it)

Your line:  
anevent = session[:user\_id]  
is suspicious. You try to assign session[:user\_id] to anevent, and  
there’s  
probably no way you can cast a Fixnum into an Event object,
