You can add the attributes to an array and then iterate over the same. In the loop use Object.attribute_present?(attribute_from_array) If this returns a true u have the value set for the given attribute for that object, else u update it.
eg :
A model book have following attributes : name, author, publish_date
Make an array : BOOKATTRIBUTES = [ 'name', 'author', 'publish_date']
Use the following loop:
BOOKATTRIBUTES.each do |attr|
if @book.attribute_present?(attr)
#don't set anything its already set.
else
# set the value of the attribute for the object
end
end
