How to add to multiple models in mongoose? - express

Question

I want to update/push to multiple mongoose mode with a single payload. E.g. I have a VolSchema, a CaseSchema and a JudgeSchema. I will like to push values to the VolSchema and the JudgeSchema whenever a new Case is being created. Already it works fine when I update only the VolSchema, but when a add the JudgeSchema, I only get the Judge model updated without the Vol model.
Model/Cases.js
const mongoose = require("mongoose");
const CasesSchema = new mongoose.Schema({
title: String,
vol: { type: mongoose.Schema.Types.ObjectId, ref: "Vol", required:
true },
judges: [{ type: mongoose.Schema.Types.ObjectId, ref: "Judge" }],
});
module.exports = mongoose.model("Cases", CasesSchema)
Models/Vol.js
const mongoose = require("mongoose");
const VolSchema = new mongoose.Schema({
vol_no: {
type: String,
unique: true,
uppercase: false,
},
cases: [{ type: mongoose.Schema.Types.ObjectId, ref: "Cases" }],
createdAt: {
type: Date,
default: Date.now,
},
});
module.exports = mongoose.model("Vol", VolSchema);
Models/Judge.js
const mongoose = require("mongoose");
const JudgeSchema = new mongoose.Schema({
name: String,
bio: String,
cases: [{ type: mongoose.Schema.Types.ObjectId, ref: "Cases" }],
});
module.exports = mongoose.model("Judge", JudgeSchema);
resolvers.js
const Vol = require("../models/Vol");
const Case = require("../models/Cases");
const Judge = require("../models/Judge");
module.exports = {
Mutation: {
addCase: async (_, { title, volID, judgesID }) => {
const newCase = await new Case({
title: title,
vol: volID,
judges: judgesID,
}).save();
const newVol = Vol.updateOne(
{ _id: volID },
{ $push: { cases: newCase } },
{ new: true },
);
const judge = Judge.updateOne(
{ _id: judgesID },
{ $push: { cases: { $each: [newCase], $position: 0 } } },
{ new: true },
);
return newVol, judge // Judge model gets updated only
return newVol // Vol gets update only
return{vol: newVol, judges: judge } // i have tried this too
},
},
};
i will like to push newCase to the Vol and also to the Judge models

Here is my best answer as I am not sure exactly what you are asking.
const Vol = require("../models/Vol");
const Case = require("../models/Cases");
const Judge = require("../models/Judge");
module.exports = {
Mutation: {
addCase: async (_, { title, volID, judgesID }) => {
const newCase = await new Case({
title: title,
vol: volID,
judges: judgesID,
}).save();
const newVol = Vol.updateOne(
{ _id: volID },
{ $push: { cases: newCase } },
{ new: true },
);
const judge = Judge.updateOne(
{ _id: judgesID },
{ $push: { cases: { $each: [newCase], $position: 0 } } },
{ new: true },
);
return newVol, judge // Judge model gets updated only
return newVol // Vol gets update only
return{vol: newVol, judges: judge } // i have tried this too
},
},
};
should look like this
const Vol = require("../models/Vol");
const Case = require("../models/Cases");
const Judge = require("../models/Judge");
module.exports = {
Mutation: {
addCase: async (_, { title, volID, judgesID }) => {
const newCase = await new Case({
title: title,
vol: volID,
judges: judgesID,
}).save();
const newVol = await Vol.updateOne(
{ _id: volID },
{ $push: { cases: newCase } },
{ new: true },
);
const judge = await Judge.updateOne(
{ _id: judgesID },
{ $push: { cases: { $each: [newCase], $position: 0 } } },
{ new: true },
);
return newCase;
},
},
};
Also because this is GraphQL it would help if I knew the return type. I would think that the return type is the Case not the newVol or judge. So in this case you would actually get weird looking results be returning something other than case. In which case the last line should read return newCase;
