I have a controller name homes, I would add the line  
map.resource :home  
so I like to return a url like  
/home/1, /home/2…etc  
but why I open up my browser  
[http://127.0.0.1:3000/home/1](http://127.0.0.1:3000/home/1)  
it appear the message like this:  
No route matches “/home/1” with {:method=\>:get}

so, what is wrong with me?

map.resource is for modelif you have a model named: home  
then you must use:  
map.resources :home  
and generate a controller named: homes
