Hi,

I added a comment model in app/models, and when I execute the  
following code:comment.commentable, the following error occurs  
NoMethodError: undefined method `commentable’ for #\<Comment…  
.  
But when I delete the comment model, it’s ok.

When add another comment model in app/models, will it override the  
default comment model provided by the plugin or just open the comment  
class?

Thanks for your help.

Rails will stop looking in its path once a constant is loaded, so you  
can’t open classes like that without a little extra effort. Your best  
bet is to either (a) hack the plugin or (b) copy the plugin’s model  
into app/models.
