Allow feature to populate embedded data

[numerical25]

Is there a reason JSON:API server doesn't allow the ability to populate embedded data ? Right now it only allows you to populate reference data and it does not allow for Multi Level Support .

I was easily able to get this to work by altering this code to MongooseAdapter.js

I am not suggesting the following code!, I am just demostrating how easy a simple feature can be added but is instead disregarded.

            queryBuilder.populate(includePaths[0]);
            includePaths.map((it) => it.split(".")).forEach((pathParts) => {
                if (!refPaths.includes(pathParts[0])) {
                    // throw Errors.invalidIncludePath({
                    //     detail: `Resources of type "${type}" don't have a(n) "${pathParts[0]}" relationship.`
                    // });
                }
                if (pathParts.length > 1) {
                    // throw Errors.unsupportedIncludePath({
                    //     detail: `Multi-level include paths like ${pathParts.join('.')} aren't yet supported.`
                    // });
                }
                //populatedPaths.push(pathParts[0]);
                //queryBuilder.populate(pathParts[0]);
            });

Can I suggest a Code Change to allow for this feature ?

Hey!

I'm not quite sure I understand what you're asking for. Can you provide some examples of how this would work? In the examples, it would help if you could include: how the document would be structured in mongo; what the incoming request would look like; and then what the desired response would be.

Im saying in the router when someone pushes a field to the populates array. Don't you think the json-server should check for the reference path and the embedded path ? Right now it only checks for a field that references another table. In my case, I am trying to populate a field called users. Here is the schema

Below The Venue Has a Embedded EventSchema assigned to it

var VenueSchema = new mongoose.Schema({
    name: String,
    address: String,
    city: String,
    state: String,
    zip: Number,
    location: {
        type: mongoose.Schema.Types.Mixed ,
        coordinates: []
    },
    created_at: {type:Date,default:Date.now},
    updated_at: {type:Date,default:Date.now, set:v => Date.now},
    events: [Event.schema]
});

The Event Schema has a ref to the User Schema

var EventSchema = new mongoose.Schema({
    name: String,
    user:{ type: mongoose.Schema.Types.ObjectId, ref: 'User' },
    start_date: Date,
    end_date: Date
});

I would just like populate the user information

router.get("/:type(venues)", Front.customAPIRequest({
    queryFactory: async (opts) => {
        const origQuery = await opts.makeQuery(opts);
        origQuery.populates.push('events.user');
        return origQuery;
    }
}));

This could easily be achieved simply by adding the includesPath to the populate. queryBuilder.populate(includePaths[0]);
