Hi All,
I'm not sure if I'm missing something but I keep having issues with getting the Aggregation Builder in Compass to generate a new stage for a workshop I'm working.
Specifically, it seems not to process the $match below:
no_empty_tab_maps = {
"$match": {
"$expr": { "$gt": [ { "$size": { "$objectToArray": "$tab_map" } }, 0 ] }
}
}
or this (when using the "copied from text" functionality")
{
$match: {
$expr: { $gt: [ { $size: { $objectToArray: "$tab_map" } }, 0 ] }
}
}
The error it returns is "n.map is not a function" is returned in all cases.
Here's a sample document (MongoShell syntax):
db.my_coll.insertOne({
"user_id": 1,
"offering": "M036/2017_November",
"tab_map": {
"_cls": "HgStudentAttemptableProblem",
"id": "5a1c7e44f62672abf36e4ba3",
"given_credit": false,
"attempts": [
{
"_cls": "HgCheckAllThatApplyAttempt",
"date": "2017-11-27 21:40:17",
"git_stamp": {
"date": "2017-11-27 21:40:11",
"revision": "789c694b49dd6d7dfbb245af7ab71bf509b0ba38"
},
"indices": [
1,
0
]
},
{
"_cls": "HgCheckAllThatApplyAttempt",
"date": "2017-11-29 14:55:01",
"git_stamp": {
"date": "2017-11-29 14:54:52",
"revision": "94556bc6f03ac374a48e4df79808b8b059c806e7"
},
"indices": [
3,
2
]
}
]
}
})
Am I missing something ? Is the tab_map underscore causing an issue with the variable name ? Is this an existing bug and is there a known workaround ? I've tried it on 1.17.0 and on 1.18 latest beta builds.
Thanks!
