Viewing list saved into a redis hash

I've saved a list into a hash but cannot figure out how to retrieve contents of the hash. Firstly, here is some code to create the list:

127.0.0.1:6379> LPUSH list1 'dc:39:79:ab:cd:ef' (integer) 1 127.0.0.1:6379> LPUSH list1 '2014-07-21' (integer) 2 127.0.0.1:6379> LPUSH list1 'Success' (integer) 3 127.0.0.1:6379> LPUSH list1 'Miscellaneous notes about the install. Can be as long as you want' (integer) 4

Now I create a hash and assign the value of one key to list1:

127.0.0.1:6379> hset hash 'RKT1234' list1 (integer) 1

How can I print the entire list saved inside hash['RKT1234'] ?

127.0.0.1:6379> hgetall hash 1) "RKT1234" 2) "list1"

127.0.0.1:6379> hvals hash 1) "list1"

thanks

It looks like you are attempting to store a list as a value in a hash. You are not doing what you think you are doing as Redis does not support nested data structures. In hset hash 'RKT1234' list1 you are not storing the list, just a string name: "list1".

In order to get the contents of list you need to first get the name of the list from the hash, then get the contents of the list in a second call.

So your sequence looks like this:

# returns "list1"
hvals hash 
lrange list1 0 -1
# returns the contents of list1
