Hello everyone!

Does the method save return the ID ?  
Because i’m doing this :

if @post.save  
flash[:notice] = ‘Post was successfully created.’  
end

and I need the ID of the post I just created. I think it could work with  
: Post.find(:last) but what if two people are posting at the same time?

Thank you!

Don’t you still have @post?

What do you mean?  
That I should do this : @post.post\_id ?

Try: puts @post.inspect

and check your logs
