jq conditional update an array element

Question

I want to conditionally update an element value based on the value of another element within the same array.

For example, I want to find name=="weather" and change checked from "true" to "false"

[
  {
    "originalSourceId": null,
    "sourceConnection": {
      "id": null,
      "version": null,
      "properties": [
        {
          "id": null,
          "version": null
        }
      ],
      "name": "POSTGRESQL",
      "businessName": null
    },
    "checked": true,
    "newlyAdded": false,
    "discoveredEntities": [
      {
        "name": "weather",
        "checked": true,
        "checkedBeforeEdit": false,
        "storeFieldsAsStrings": false
      },
      {
        "name": "weather_2",
        "checked": true,
        "checkedBeforeEdit": false,
        "storeFieldsAsStrings": false
      }
    ],
    "defaultLevel": "MANAGED"
  }
]

the checked element will update to "false" for the same object with name = "weather"

[
  {
    "originalSourceId": null,
    "sourceConnection": {
      "id": null,
      "version": null,
      "properties": [
        {
          "id": null,
          "version": null
        }
      ],
      "name": "POSTGRESQL",
      "businessName": null
    },
    "checked": true,
    "newlyAdded": false,
    "discoveredEntities": [
      {
        "name": "weather",
        "checked": false,
        "checkedBeforeEdit": false,
        "storeFieldsAsStrings": false
      },
      {
        "name": "weather_2",
        "checked": true,
        "checkedBeforeEdit": false,
        "storeFieldsAsStrings": false
      }
    ],
    "defaultLevel": "MANAGED"
  }
]

Figured it out.

jq '[.[].discoveredEntities[] |= if (.name=="weather") then (.checked = "false") else . end]'\
    ./test.json
