Issue
I have a dataset with the name of table1
in Redis like below:
[
{
"column-name1": "10.1.10.1",
"column-name2": "range(100,200)",
"column-name3": "nam3"
},
{
"column-name1": "2.2.2.2",
"column-name2": "",
"column-name3": "range(1024,+inf)"
},
{
"column-name1": "1.1.1.1",
"column-name2": "",
"column-name3": "nam3"
}
]
I want to get values of table1
.. How can I do it?
How can I parse table1
in ruby to reach its values?
Solution
Frist, you should parse json data from stored string in Redis. For parsing json in Ruby you can do something like below:
require "redis"
require "json"
red = Redis.new(host: "127.0.0.1", port: 6379, db: 1) <-- connect to redis
table1 = red.get("table1") <-- get table1 value (stringified data)
table1_json = JSON.parse(table1) <-- parse value to get a JSON object
now you have your table1 data as a json object and you can iterate over its elements and get the values you want:
for key in table1_json
puts(key["column-name1"])
end
