The following method will return if the value associated with a token/key
is expired or not.
def check_token_expiry(token)
Rails.cache.read(token).nil?
end
Basically, try to read the value from cache. If it is expired, read method will return nil.

When you specify the expires_in: 21.days
while caching, you tell underlying cache store to store the data for given key(here token
) for 21 days, after 21 days it gets expired means data is no longer available for the give key you use exist?
method to check this.
Rails.cache.exist?(token) # => true (data is available and you read)
Rails.cache.exist?(token) # => false (cache is expired, data is not available)

When you specify the expires_in: 21.days
while caching, you tell underlying cache store to store the data for given key(here token
) for 21 days, after 21 days it gets expired means data is no longer available for the give key you use exist?
method to check this.
Rails.cache.exist?(token) # => true (data is available and you read)
Rails.cache.exist?(token) # => false (cache is expired, data is not available)
