Question

I want to find all records, say Posts, created today with Ruby on Rails, then all Posts created yesterday, and so on… how should I do?

Thank you,

Kevin

Answer 1

Try this:

#Today
Posts.find(:all, conditions: { :created_at => Date.today...Date.today + 1 })
#Yesterday
Posts.find(:all, conditions: { :created_at => Date.today - 1...Date.today })

Or this (preferable, in my opinion):

#Today
Posts.find(:all, conditions: ["DATE(created_at) = ?", Date.today] )
#Yesterday
Posts.find(:all, conditions: ["DATE(created_at) = ?", Date.today - 1] )
