I am reading Agile Web D. with Rails, Edition 3. which is  
based on Rails 2.X  
now I am coding on Rails 3  
So I go to the author’s website to see the difference between ver 2  
and ver 3

In this webpage, 4.1 Creating a New Application

It said  
“edit config/routes.rb, and uncomment the following line:  
match ‘:controller(/:action(/:id(.:format)))’ ”

In Rails 3 , is it necessary to uncomment this line whether I add a  
view into a controller manually  
( I mean not use the command rails generate controller xxx xxxx )?  
Is there any security problem after I uncomment this line?

Thank you.

I’m working through this page right now, it seems to be a good place

Try building this example (starts at chapter 3, where you get to

match ‘:controller(/:action(/:id(.:format)))’

will make all your actions available through get request. so be sure to  
hide  
internal actions behind a private clause

Thanks! that’s the point what i care about.  
Private actions won’t be changed to accessible by uncommenting this  
line. isn’t it?  
OK , I got it
