Join with where clause that filters out specific records, rails active record

Question

I am making a sports application with leagues and events, the events contain a league_id , the leagues have a name and an country_name . How can I get all the event with starting date today together with the league name and country.

I tried:

League.joins(:events).where(events: {event_start: Time.zone.now..Time.zone.now.end_of_day})

But this returns all the leagues that have an event today, when I then try to access the events from that specific league, all events are included and not only the ones that are being plaid today.

Answer 1

从Event s开始，并包括相关的League以避免N + 1问题。

Event.includes(:league).where(event_start: Time.zone.now..Time.zone.now.end_of_day)

Answer 2

To get all the event with starting date today, I think you need to search between beginning_of_day to end_of_day

Event.includes(:league).where(event_start: Time.zone.now.beginning_of_day..Time.zone.now.end_of_day)

or

Event.includes(:league).where("event_start >= ? && event_start <= ?", Time.zone.now.beginning_of_day, Time.zone.now.end_of_day)
