Rails cache expire at midnight every day

Is there a way to do something like

Rails.cache.fetch("id..", expire_in: 1.day, expire_at: midnight) do
  #...
end

thanks!

Careful not to get a decimal, if you want an integer...

>_ bundle exec rails console
Loading development environment (Rails 6.0.3.2)
 >> Time.now.end_of_day + 1.day - Time.now
169207.001996682
 >> (Time.now.end_of_day + 1.day - Time.now).to_i
169204

you can set expire time when you are creating it

Rails.cache.write("your key or id", expires_in: 1.day)

There isn't an expires_at option, but you can quickly calculate the number of seconds between your desired expiration time and the current time. Assuming you mean "expire at the end of the day tomorrow", you could do something like this:

expires_in_seconds = Time.now.end_of_day + 1.day - Time.now
Rails.cache.fetch("id...", expires_in: expires_in_seconds) do
  #...
end

Where expires_in_seconds would return a number of seconds (e.g. 90559)

If you just mean "end of today", it would be Time.now.end_of_day - Time.now.
