Hi all,

Hopefully this is easy for you guys. I’m trying to output a list of  
usernames and everything has been working well. However, when I added a  
user with a period in their username it generates this error. If I  
rename the user to “Tom\_Dixon” it works fine, but “Tom.Dixon” fails.

Any clue how to get this to work?

Error:

user\_url failed to generate from {:controller=\>“users”, :action=\>“show”,  
:id=\>#\<User id: 96, username: “Tom.Dixon” …

The code is your standard rails link\_to:

\<%#= link\_to h(user.username), user\_path(user) %\> \<%#= link\_to 'Edit', edit\_user\_path(user) %\> \<%#= link\_to 'Remove', user, :confirm =\> 'Are you sure?', :method =\> :delete %\>

Any help is appreciated!

-Tony

Why are you calling user\_path(user) instead of just the id?
