Select number keys in data file

support

I have a json file that looks like this:

status: [
                {
                    "0":"val",
                    "1":"val",
                    "2":"val"
                },
                {
                    "0":"val",
                    "1":"val",
                    "2":"val"
                }
           ]

I have numbers as keys in json file but I am not able to select those inside my templates. I also considered changing the numbers into words but the size of the file is humongous. Is there a way to select number keys inside templates?

Number keys are not allowed, as far as I know.

Okay. Thanks. I guess I’ll have to find a way to convert numbers to words.

Are your keys always starting and counting up from 0? Then you can just leave them out. Check this answer on stackoverflow about this:

Your keys are not numbers; they are string representations of numbers. This only presents a problem when trying to access the corresponding values using dot notation.

TLDR: Use the index function.

Example 1

data/status.json

[
  {
    "a": "foo",
    "b": "bar",
    "c": "baz"
  }
]

code

{{ range .Site.Data.status }}
  dot notation: {{ .a }}<br>
  index function: {{ index . "a" }}<br>
{{ end }}

result

dot notation: foo
index function: foo

Example 2

data/status.json

[
  {
    "0": "wibble",
    "1": "wobble",
    "2": "wubble"
  }
]

code

{{ range .Site.Data.status }}
  dot notation: {{ .0 }}<br>
  index function: {{ index . "0" }}<br>
{{ end }}

result

dot notation: 0
index function: wibble

This is perfect! Thank you.
