Setting model value conditional in rails?

Question

i have a model with the following field

• published (boolean)
• published_at (datetime)

when updating the model, i want to set published_at to Time.now when published is set true!

any advice how i can achieve this? thanks!

Answer 1

In your model you need to put this

before_save :set_published_at

def set_published_at
    @published_at = Time.now if @published == true
end
