Convert array of objects as string into array of hashes?-CodePudding

from this

["{\r\n  \"charge_type\": \"sports\",\r\n  \"amount\": 1000\r\n},{\r\n  \"charge_type\": \"servicing\",\r\n  \"amount\": 550\r\n}"]

to this

[{"charge_type"=>"sports", "amount"=> "1000"},{"charge_type"=>"servicing", "amount"=> "500"}]

I have tried this,

JSON.parse(["{\r\n  \"charge_type\": \"sports\",\r\n  \"amount\": 1000\r\n},{\r\n  \"charge_type\": \"servicing\",\r\n  \"amount\": 550\r\n}"].first)

But could not figure it out. Any help will be appreciated.

It's not clear what you're trying to do with the [...].first part. What you really need is:

JSON.parse("[{\r\n  \"charge_type\": \"sports\",\r\n  \"amount\": 1000\r\n},{\r\n  \"charge_type\": \"servicing\",\r\n  \"amount\": 550\r\n}]")

CodePudding user response：

You are having problem because your array [] is not wrapped around string, it need to be "[]" then it will work.

e.g your current json will give error

unexpected token at ',{
  "charge_type": "servicing",
  "amount": 550

but if your json is completely wrapped inside string like this (notice " around array)

my_json = "[{\r\n  \"charge_type\": \"sports\",\r\n  \"amount\": 1000\r\n},{\r\n  \"charge_type\": \"servicing\",\r\n  \"amount\": 550\r\n}]"

then you can do something like this

JSON.parse(my_json)

which will return

[{"charge_type"=>"sports", "amount"=>1000}, {"charge_type"=>"servicing", "amount"=>550}]
