Forced inclusion of varaibles in validate command as well as step
Hello all
I am a very new R user
I am used to using STATA

How to render from with <%%> ?
I have a loop that I iterate through in my view.
<%
coll.each do |itm|
puts(itm.value)

Hi,
I am facing a serious problem with file_column plugin. Though it is
