Ruby on Rails- Time Condition

Question

I want to compare the current time with submission with Datetime stamp to setup a controller which only shows submission of a specific time. Such as posts done in past hour, day or week.

So I don't get how to access current time. Does it need to be part of database? How can it be defined and how to compare it which post submissions?

Answer 1

From the below query you will get the posts that got created one hours ago.

now = Time.now

@posts= Post.where(created_at: (now - 1.hours)..now)

To get posts created one week ago

@posts = Post.where("created_at > ?", Time.now - 7.days)

Answer 2

To add to the earlier answer

For posts this week

@posts = Post.where("created_at > ?", Time.now.beginning_of_week)

For posts this month:

@posts = Post.where("created_at > ?", Time.now.beginning_of_month)
