hi, hope u’r all having a good week ahead -
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
