[Please help!]store parameters variable into database

Rails
1

So here’s what I’m trying to do
I’m going to store params variables into database.
Here’s what it’s looklike.

------------------------Data that store on my database --------------
— !map:HashWithIndifferentAccess
“15”: “1”
“16”: “1”
2-Medium: “0”
1-High: “1”
3-Low: “0”

So I need to call this parameter from database then pass it on the page
once again But It’s not like the previous parameter so any idea?

Please help!!

One way is to save a serialized hash into the db and you can deserialize
the saved hash object back to params.

How to serialize would you mind giving me some example.
suppose that I’ve session[‘test’] which store several params inside
such as
session[‘test’] = idlist[‘1’]=test&idlist[‘2’]=test2

so I need to store this stuff inside my DB so if I need to serialized
what I have to do?

require ‘yaml’

serialized = obj.to_yaml
new_obj = YAML::load(serialized)
puts new_obj.width

if those colons (“:”) are in the db, you have almost-readymade json.

Thx here’s what’s store inside my db for now

— !map:HashWithIndifferentAccess
2-Medium: “1”
“17”: “1”
“18”: “1”
3-Low: “1”
1-High: “1”
“20”: “0”
“19”: “1”

It’s that correct one? if so how can I call this one back to
session[‘test’] ?
