I need to dynamically render links to different routes in the view based  
on a parameter. Currently, this code below is functioning fine. But it  
makes use of url\_for, which is a deprecated API call. Are there better  
ways to do this?

is\_admin? ? :“admin\_#{name\_of\_route}\_url” : :"#{name\_of\_route}\_url"

url\_for isn’t deprecated; it’s passing a symbol to it that’s  
deprecated. You can avoid this by wrapping a send() around it:

is\_admin? ? send(:“admin\_#{name\_of\_route}\_url” :  
:“#{name\_of\_route}\_url”)

Seems like there should be a better way. At least put that stuff in a  
helper method.

Thanks, that helps with the deprecated warning! Yes, this is definitely  
in a helper because it is used throughout the site. Here’s what I went  
with:

is\_admin? ? send(:“admin\_#{name\_of\_route}\_url”) :  
send(:"#{name\_of\_route}\_url")

Oops, what I posted was a syntax error. Sorry! That looks much better.
