this may be a slightly unrelated question, but i was hoping someone had  
some small quick answer for me … does anyone know how to modify /  
change existing text in a db?

with the code

@foods = Food.find(:all)  
food\_rows = @foods.collect(&:fruit)  
food\_rows.each |r|  
r.gsub(“really”, “”)  
end

i get a good end result (if the data was

Food.find(1).fruit = “we really need apples”  
Food.find(2).fruit = “we really need kiwis”  
Food.find(3).fruit = “we really need oranges”

that is, after the code, i get

“we need apples”  
“we need kiwis”  
“we need oranges”

which is good, but that is the program’s output. i was wondering whether  
someone knew a way to do this, that modifies the data in the database  
(mysql).

thanks for the hassle
