I have user model
const mongoose = require("mongoose");
const uniqueValidator = require("mongoose-unique-validator");
const userSchema = mongoose.Schema({
email: { type: String, required: true, unique: true },
password: { type: String, required: true },
isEmailVerified: { type: Boolean },
registrationStep: { type: Number, enum: [0,1,2,3]},
regDate: { type: Date },
companyName: { type: String },
oib: { type: String },
telephone: { type: String },
address: { type: String },
city: { type: String },
countryCode: { type: String },
postalCode: { type: String },
userType: { type: String, enum:['firms','drivers','both']},
approved: { type: Boolean },
isAdmin: { type: Boolean }
});
userSchema.plugin(uniqueValidator);
module.exports = mongoose.model("User", userSchema);
and documents model
const mongoose = require("mongoose");
const docsSchema = mongoose.Schema({
docsPath: { type: String, required: true },
creator: { type: mongoose.Schema.Types.ObjectId, ref: "User", required: true },
docType: { type: String, enum:['isr','lmp','pocmr'], required: true }
});
module.exports = mongoose.model("Docs", docsSchema);
I want to join collections so that for every user exists the user_docs field with docs data as in code below. I'm trying to do that with joining _id with creator as it is defined when creating a document
exports.getUsersAndDocs = (req, res, next) => {
const query = User.aggregate([
{
$lookup: {
from: "Docs",
localField: "_id",
foreignField: "creator",
as: "user_docs"
}
}]);
query
.then(fetchedUsers => {
res.status(200).json({
message: "Users fetched successfully!",
users: fetchedUsers,
});
})
.catch(error => {
res.status(500).json({
message: "Fetching users failed!"
});
});
};
I'm recieveing empty user_docs array. Thank you for your help
If someone has the same problem. I solved it by changing
from: "Docs"
to
from: Docs.collection.name
