This will set the new value only if the old value is blank

@user = User.new(user_params)
@user.profilePicture ||= "/assets/images/default_image.jpg"

If profilePicture could be an empty string then we might treat it like this

@user.profilePicture = "/assets/images/default_image.jpg" if @user.profilePicture.empty?
