        matchesSchema.js

So I have 4 schema's and I want to use the other schema's in the all my schema's but when I import it I get an error:

C:\Users\phara0h\Dropbox\esports-scores\nodeTest\node_modules\mongoose\lib\schema.js:425
      throw new TypeError('Invalid value for schema Array path `' + prefix + key + '`');
      ^

When I console.log the imported variable they are undefined.

playersSchema.js:

tournamentsSchema.js

import mongoose, { Schema } from 'mongoose';
import timestamps from 'mongoose-timestamp';
import { PlayersSchema } from './playersSchema';
import { MatchesSchema } from './matchesSchema';
import { TeamsSchema } from './teamsSchema';

// Mongoose Schema definition
export const TournamentsSchema = new Schema({
    description: String,
    endDate: String,
    itemdef: Number,
    leagueid: Number,
    matches: [MatchesSchema], //<--- this causes the error
    name: String,
    organizer: String,
    production: String,
    prizepool: String,
    players: [PlayersSchema],
    results: String,
    startDate: String,
    teams: [TeamsSchema],
    tournamentUrl: String
});
TournamentsSchema.plugin(timestamps);
TournamentsSchema.index({ description: 'text', name: 'text', organizer : 'text' });
export const TournamentsDB = mongoose.model( 'Tournaments', TournamentsSchema );

Yes I could put them all in one file but since they all use each other but on the page lower schemes can't be included in to the above ones.

Thanx in advanced

• javascript
• node.js
• mongodb
• mongoose
• mongoose-schema

• It's checking in the wrong directory nodeTest\node_modules\mongoose\lib\schema.js, notice the 1st line of the error. I'm sure your schemas are in a different directory... Just change the import line from ./playersSchema to properly point to the correct directory/path – Searching Commented Apr 20, 2017 at 1:07
• @Searching added the file structure, as you can see they are all located in the same directory – Phara0h Commented Apr 20, 2017 at 10:20
• So yup the import statement should be something like /schemas/playerschema, and similar. – Searching Commented Apr 20, 2017 at 20:20
• @Searching I think you're misunderstanding me these are the files I got the issue with: they are all located in the same folder. schema/matchesSchema.js, schema/playersSchema.js, schema/matchesSchema.js, schema/teamsSchema.js and schema/tournamentsSchema.js So I want to include all the above mentioned files in each other, and they are all located in the same folder. – Phara0h Commented Apr 21, 2017 at 8:22

All is good, but it seems that we need to explicitly ask for the schema part of the object.

Instead of player: [PlayersSchema],

try player: [PlayersSchema.schema]

My solution what is more a work around: removed all the inclusions of the other schema's and made them

Schema.Types.Mixed

In the end I didn't need to do this since I made a graphQL server and I realized that GraphQL handled the output/input in a manner I wanted without having to define it in Mongoose.
