I am not great with MongoDB advanced technique. My record in mongo db collection
{
"_id": ObjectId("1"),
"manager": ObjectId("12345"),
"code": "PS",
"title": "Performance System",
"users": [
{
"_user": ObjectId("1"),
"role": "Member",
},
{
"_user": ObjectId("2"),
"role": "Member",
},
{
"_user": ObjectId("3"),
"role": "Member",
}
],
}
I created API to update the array like below but did not work.
const updateProjectMember = asyncHandler(async (req, res) => {
const { userID, role } = req.body.userData;
try {
const project = await Project.updateMany(
{ _id: req.params.projectID },
{ $set: { "users.$[selectedUser].role": role } },
{ arrayFilters: { "selectedUser._user": { $in: userID } } }
);
res.status(200).json(project);
} catch (error) {
res.status(400);
throw new Error(error);
}
I use the API parameter to get project ID. Here the request body data
{
userID : ["2","3"];
role: "Admin"
}
So the API will get array of userID to match and set all "role" field to "Admin" to all matched.
I wanted the data to be like this
{
"_id": ObjectId("1"),
"manager": ObjectId("12345"),
"code": "PS",
"title": "Performance System",
"users": [
{
"_user": ObjectId("1"),
"role": "Member",
},
{
"_user": ObjectId("2"),
"role": "Admin",
},
{
"_user": ObjectId("3"),
"role": "Admin",
}
],
}
Am I doing right practice? If it bad practice, what is the best way to solve this.
The query is fine. Just make sure that you pass the value with the exact type as in the MongoDB document.
var mongoose = require('mongoose');
const updateProjectMember = asyncHandler(async (req, res) => {
const { userID, role } = req.body.userData;
userID = userID.map(x => mongoose.Types.ObjectId(x));
try {
const project = await Project.updateMany(
{ _id: mongoose.Types.ObjectId(req.params.projectID) },
{ $set: { "users.$[selectedUser].role": role } },
{ arrayFilters: { "selectedUser._user": { $in: userID } } }
);
res.status(200).json(project);
} catch (error) {
res.status(400);
throw new Error(error);
}
}
