How to delete a key using HDEL if the key have space with it

Question

I am using Ruby 2.5.1 and trying to delete keys from redis using HDEL. But it doesn't work key with spaces. I can delete with the quotes from redis-cli but I need to write a code to delete keys with space.

Sample value

["play group_1", "{\"id\":\"1\",\"name\":\"Play Group\"}"]

Delete not working in redis-cli (If doesn't passing single quotes with in it),

127.0.0.1:6379> HDEL development_groups play group_1
(integer) 0

Delete works in redis-cli (If passing single quotes with in it),

127.0.0.1:6379> HDEL development_groups 'play group_1'
(integer) 1

Ruby code,

redis.hdel(index, key)

How to delete keys with space using HDEL?

To ask the obvious, have you tried passing the key in single quotes from your Ruby code? — Tim Biegeleisen, Jun 24 '19 at 06:15
Yes, I tried but it passing this "'play group_1'" my code, redis.hdel(index, "\'" + key+ "\'") — SST, Jun 24 '19 at 06:17
You should check the documentation for the Redis API which you are using with Ruby. This is the first place to look. — Tim Biegeleisen, Jun 24 '19 at 06:18
