Can anyone tell me what the difference is in these two statements? Yes, I'm a newbie!
<%=h device.send(column.name) %>
<%= device.send(column.name) %>
Specifically, what is the <%=h supposed to do? The "h" doesn't appear to do anything that I can find, yet RoR generates code using it...
Thanks much!

h is a short form for is a short form for the method html_escape.
So IMHO it's more clear to write something like
<%= h(device.send(column.name)) %>

OK, I guess that's clear enough... but it doesn't actually seem to make any difference if the "h" is in there or not. And I can't seem to determine why Ruby on Rails sometimes generates code with the "h", and sometimes it doesn't 
Thank,

Try:
<%= h "< & >" %>
and:
<%= "< & >" %>
