Add user to group, from script / python.

[MoJo]

From yesterday im trying to add/remove user from group, im new to mongodb and nodebb js.

Im using python as backend.

So i just checked how adding user to group is done in NodeBB.
https://github.com/NodeBB/NodeBB/blob/master/src/groups/join.js#L41

	const promises = [
		db.sortedSetsAdd(groupsToJoin.map(groupName => 'group:' + groupName + ':members'), Date.now(), uid),
		db.incrObjectField(groupsToJoin.map(groupName => 'group:' + groupName), 'memberCount'),
	];
	if (isAdmin) {
		promises.push(db.setsAdd(groupsToJoin.map(groupName => 'group:' + groupName + ':owners'), uid));
	}

https://github.com/NodeBB/NodeBB/blob/b61a4da50c192924426ed3620cea91f51952901f/src/database/mongo/sorted/add.js#L50

module.sortedSetsAdd = async function (keys, scores, value) {
        ...
	var bulk = module.client.collection('objects').initializeUnorderedBulkOp();
	for (var i = 0; i < keys.length; i += 1) {
                console.info("KEYS[i]: " + keys[i] + " value: " + value + " SCORE:" + scores);                                                                 
		bulk.find({ _key: keys[i], value: value }).upsert().updateOne({ $set: { score: parseFloat(isArrayOfScores ? scores[i] : scores) } });
	}
	await bulk.execute();

Just addded console.info that showed these keys when i was adding users from ACP:

KEYS[i]: group:group_A:members value: 2 SCORE:1596909662460
KEYS[i]: events:time value: 28 SCORE:1596909662470
KEYS[i]: events:time:group-add-member value: 28 SCORE:1596909662470

group_A is a group that i want to add user to, user id is 2.

and this is my python code:

import pymongo

collection = db['nodebb']

query={"_key":"group:group_A:members","value": "2"}

x = collection.update(query, values)

    print(y)

x = collection.update(query, values)                                                             
for y in x:                                                                                      
    print(y)                                                                                     
                                                                                             
query={"_key":"events:time:group-add-member","value": "28"}                                      
values={"$set": {"score": float(1596909662470)}}                                                 
x = collection.update(query, values)                                                             
for y in x:                                                                                      
    print(y)

python output:

n
nModified
ok
updatedExisting
n
nModified
ok
updatedExisting
n
nModified
ok
updatedExisting

I just cant get it, i think the _key might be wrong.

Group membership data is cached in nodebb so adding in db won't work without clearing the cache.

Hm, I thought it should show user in group after restarting NodeBB, or even when nodebb is turned off (then add user and start nodebb).

If i understand correct, script.js with Groups.join('administrators', 2) fired by node script.js should add user to group?

Groups.join('administrators', 2);

I'm don with this, its to much for me right now, but ...

anyway I'm going to try nodebb-plugin-write-api, i think is the right way, prepare for questions

I should use API earlier, i was trying to avoid generating token for each forum but looks like it is the right way of doing it. Thanks for the input.
