How to DRY up this model a bit?

Rails
1

Hi again,

I have this model, trip.rb, which is getting bloated with the same
things repeated all over. I’m new to both rails and ruby so I’m
looking for help on how to DRY this thing a bit

I basically have to repeat this a lot of time (replacing “departure”
and “departures” with other models) and I would love to find a way to
write it once :slight_smile:

def new_departure_attributes=(departure_attributes)
departure_attributes.each do |attributes|
departures.build(attributes)
end
end

def existing_departure_attributes=(departure_attributes)
departures.reject(&:new_record?).each do |departure|
attributes = departure_attributes[departure.id.to_s]
if attributes
departure.attributes = attributes
else
departures.delete(departure)
end
end
end

def save_departures
departures.each do |departure|
departure.save(false)
end
end

Can anyone educate me a bit? :slight_smile:

Thanks
