Really basic question.

How can I convert “this” to ‘this’

convert from a double quotes string to a single quotes string.

I could be misreading, but I thought it was a simple question of how to  
change double quotes to single quotes.

try  
var = ‘“this”’  
var.gsub!(’"’,"’")

Cheers

Try this one :-  
str = ‘“hai”’  
puts str  
puts str.sub(/^"(.\*)"$/, ‘’\1’’)

Thanks guys, was having some issues creating headings based on an  
array of column names from the DB acquired using User.column\_name  
where “User” is the table. Turns out my problem was unrelated in the  
link\_to code…should have went to bed sooner.
