Me No Blog Hella Ugly!

Welcome to the 2000’s, self!
I’m ever so excited to be blogging at a blog that not only understands code highlighting, but doesn’t look like it was crafted by a mad scientist with cataracts in 1992. Now it looks more like it was crafted by a mad scientist without cataracts circa 2008 — which is an entirely more accurate representation of the truth.
That’s the good news.
The bad news? That I have don’t anything meaningful to report in this post.
Maybe I’ll just write some highlighted code instead.
# ---------------------------------------------------------------------------
# options[:except_list]: list of symbols that we will exclude form this copy
# options[:dont_overwrite]: if true, all attributes in from_model that aren't #blank? will be preserved
def self . copy_attributes_between_models ( from_model, to_model, options = { } )
return unless from_model && to_model
except_list = options [ :except_list ] || [ ]
except_list << :id
to_model. attributes . each do | attr, val |
to_model [ attr ] = from_model [ attr ] unless except_list. index ( attr. to_sym ) || ( options [ :dont_overwrite ] & amp; & amp; !to_model [ attr ] . blank ? )
end
to_model. save if options [ :save ]
to_model
end def created_date
created_at.strftime("%Y.%m.%d")
end
def updated_date
updated_at.strftime("%Y.%m.%d")
end
