def find_or_new(attrs, set_attrs=nil)
  obj = find(attrs) || new(attrs)
  obj.set(set_attrs) if set_attrs
  yield obj if block_given?
  obj
end

#update_or_create(attrs, set_attrs = nil, &block) ⇒ Object

Attempt to find an record with the attrs, which should be a hash with column symbol keys. If such an record exists, update it with the values given in set_attrs. If no such record exists, create a new record with the columns specified by both attrs and set_attrs, with the ones in set_attrs taking priority. If a block is given, the object is yielded to the block before the object is saved. Returns the new or updated object.
