hi.  
in my routes.rb, I have such url  
map.file ':user/:file  
it works well with following url:

1. jay/web
2. jay/web2  
but it encounters error with: jay/web2.0  
it displays : no route found to match “/post/web2.o” with  
{:method=\>:get}  
I guess it is because the char ‘.’ and rails can not translate it  
exactly.

How can I fix it ?  
thank you  
zico

I haven’t tested it but try something like:

:requirements =\> { :user =\> /._/, :file =\> /._/ }

thanks.it works well now.  
but if I want to user such url: jay.zhang/web2.0.  
I tried to change the route into:  
1.:user =\> ‘all’, :file =\> ‘all’ , :requirements =\> { :user =\> /._/  
} , :requirements =\> { :file =\> /._/ }  
2.:user =\> ‘all’, :requirements =\> { :user =\> /._/ } , :file =\> ‘all’  
, :requirements =\> { :file =\> /._/ }  
but it seems that it does not take effect.  
how to write the route in this kind of situation?  
Thanks again.

I just tested it and it works for me with Rails 1.2.2.

routes.rb:

map.connect ‘/:user/:file’, :controller =\> “main”, :action =\> “index”,  
:requirements =\> { :user =\> /._/, :file =\> /._/ }

views/main/index.rhtml:

\<%= params[:user] -%\>  
  
\<%= params[:file] -%\>

If I input:

[http://locahost:3000/john.doe/file.ext](http://locahost:3000/john.doe/file.ext)

I see in my browser:

john.doe  
file.ext
