You're not saving the child after you update it's value
for child in @children do
child.commissions_rate = @rate
child.save
end
or
for child in @children do
child.update_attribute(:commissions_rate, @rate)
end
.update_attribute automatically saves, check the Rails API docs for
more info on using this method.
PS You're using a lot of instance variables there, which seem like
there would be better scoped as local variables (ie drop the @ from
the variables unless you need them to be accessible on an instance of
the object - @destination is probably the only legitimate instance
variable)
