String

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

You need to .save the individual Food records. Something like
(untested):

Food.find(:all).each{ |food|
food.fruit = food.fruit.gsub( “really”, “” )
food.save
}
