Method: ActiveSupport::Cache::RedisStore#increment

Defined in:

lib/active_support/cache/redis_store.rb

#increment(key, amount = 1) ⇒ Object

Increment a key in the store.

If the key doesn’t exist it will be initialized on 0. If the key exist but it isn’t a Fixnum it will be initialized on 0.

Example:

We have two objects in cache:
  counter # => 23
  rabbit  # => #<Rabbit:0x5eee6c>

cache.increment "counter"
cache.read "counter", :raw => true      # => "24"

cache.increment "counter", 6
cache.read "counter", :raw => true      # => "30"

cache.increment "a counter"
cache.read "a counter", :raw => true    # => "1"

cache.increment "rabbit"
cache.read "rabbit", :raw => true       # => "1"

# File 'lib/active_support/cache/redis_store.rb', line 63

def increment(key, amount = 1)
  log "increment", key, amount
  @data.incr key, amount
