So if I understand you correctly, it sounds like you have two models: A and B. Model A has an attribute that allows text to be stored in it, and this attribute is populated by model B. So, what you want to do is:
class B < ActiveRecord::Base
# id: the id of the record where the text should be stored # text: the text to be stored def populate_text_field(id, text) if a = A.find(id) a.update_attribute(:text_field, text) end end
end
Is this what you are intending?
