method

increment

v5.2.3 - Show latest stable - Class: ActiveSupport::Cache::RedisCacheStore

increment(name, amount = 1, options = nil)

public

Increment a cached value. This method uses the Redis incr atomic operator and can only be used on values written with the :raw option. Calling it on a value not stored with :raw will initialize that value to zero.

Failsafe: Raises errors.
