</div>

in the application.rhtml I am trying to check and see if any of the  
models associated with this controller have errors (i.e. -  
model.errors.count \> 0). Does anyone know how to do that using  
reflection or something since I will not know what models are present  
in this controller or action of the controller since it is in the  
shared application.rhtml file??

Thanks!

In your controller you could define a flash message:

def create  
@thing = Thing.new(params[:thing])  
if @thing.save  
flash[:notice] = “Thing was saved correctly.”  
else  
flash[:notice] = “Thing could not be saved: #{@thing.errors.to\_s}”  
end  
end
