How to select on existing (or non existing) key/value pair in sub structure - filter

Question

I have the following (simplified) JSON object:
{
"data": {
"items": [
{
"id": 2584,
"customProperties": [
{
"name": "jira.assetid",
"value": "1"
},
{
"name": "system.categories",
"value": "collector"
}
]
},
{
"id": 2603,
"customProperties": [
{
"name": "system.categories",
"value": "snmp"
}
]
},
{
"id": 2703,
"customProperties": [
{
"name": "jira.assetid",
"value": "5"
},
{
"name": "system.categories",
"value": "snmpTCPUDP,Netsnmp,snmpHR,snmp"
}
]
}
]
}
}
How can I filter all devices which have (or don't have) a "jira.assetid"?
My goal is to get 2 outputs:
No jira.assetid present: id, jira.assetid
Yes jira.assetid present: only id
The following gives me the id's of the devices with a jira.assetid, but how to get the assetid also on the output:
cat devices.txt | jq -r '.data.items[]
| select(.customProperties[].name == "jira.assetid")
|.id'

Answer 1

Here are at least two possible solutions, one first building a list of all id + assetid combinations, the other converts the custom properties to an object first.
Streaming solution:
.data.items[]
| {
id,
assetId: (.customProperties[] | select(.name == "jira.assetid").value)
}
Object solution:
.data.items[]
| {
id,
assetId: (.customProperties | from_entries."jira.assetid")
}
| select(.assetId)
Or using the special empty filter instead of selecting a second time:
.data.items[]
| {
id,
assetId: (.customProperties | from_entries."jira.assetid" // empty)
}
Output:
{
"id": 2584,
"assetId": "1"
}
{
"id": 2703,
"assetId": "5"
}
To get only the elements without an assetid:
.data.items[]
| select(any(.customProperties[]; .name == "jira.assetid") | not)
| { id }
or by building an object first, which I find slightly easier to grok:
.data.items[]
| select(.customProperties | from_entries | has("jira.assetid") | not)
| { id }
Output:
{
"id": 2603
}
To get only the ids for items without asset id:
.data.items[]
| select(.customProperties | from_entries | has("jira.assetid") | not)
| .id
Output:
2603
