Good Friday Everyone :-). These are my models: Problem -> has_and_belongs_to_many :tags Tag -> has_and_belongs_to_many :problems Now if a tag does not exist and I create it and associate it to the problem it works self.tags << Tag.create(:name => tag) But if I have the tag already in the DB and just want to link it to another problem it does not really like me.

Is it worth

In the migration I also want to go back and set the value of the created_at and updated_at columns for the previous rows. What is the best way to do that? Initially I thought I was being smart and decided to put an UPDATE SQL query in a find_by_sql statement and
