Ciao a tutti,  
non riesco a cancellare dei record.

Ogni suggerimento sarà vivamente apprezzato

Ecco quello che combino:

nel Controller:

* * *

def destroy

if params[:agtion\_id] != nil  
@agtion = Agtion.find(params[:agtion\_id])  
@course = Course.find(params[:id])  
else  
@agtion = Agtion.find(4) # 4 in locale, 7 in produzione  
@course = Course.find(params[:id])  
end

```
    @course.destroy respond_to do |format|
format.html { redirect_to Agtion_courses_path(@agtion) }
format.xml { head :ok }

```

end  
end

* * *

Errore:

* * *
