Problems with default values for updated_at and created_at with SQL migrations in Rails?

I found the cause of my problems, which as it happens, has nothing to do with SQL migrations, created_at or schema. Rb, but is caused by failing the validation validates publication_year, numericality: { only_integer: true, less_than_or_equal_to: Date.today.year() } when publication_year is nil .

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
