Schema must contain unique named types but contains multiple types named

[sibelius]

I defined my models in different files using mongoose, when I try to import all of them I receive this erro:

Schema must contain unique named types but contains multiple types named

Can you copy - paste your schema code? It seems that you have multiple types or fields with the same name.

[sibelius]

A.js

import mongoose from 'mongoose';
export const ASchema = new mongoose.Schema({
  name: {
    type: 'String',
  },
},{ collection: 'a'});
export const A = mongoose.model('A', ASchema);

B.js

import mongoose from 'mongoose';
import {ASchema} from './A';

export const BSchema = new mongoose.Schema({
  name: {
    type: String,
  },
  attributes: [ASchema]
}, { collection: 'b'});
export const B = mongoose.model('B', BSchema);

C.js

import mongoose from 'mongoose';
import {ASchema} from './A'

export const CSchema = new mongoose.Schema({
  description: {
    type: String,
  },
  attributes: [ ASchema ],
}, { collection: 'c'});
export const C = mongoose.model('C', CSchema);

server.js

import {getSchema} from '@risingstack/graffiti-mongoose';
import graffiti from '@risingstack/graffiti';
import express from 'express';
import {A} from './A';
import {B} from './B';
import {C} from './C';

const GRAPHQL_PORT = 8080;

mongoose.connect(process.env.MONGO_URI || 'mongodb://localhost/brandlovers');
const app = express();
app.use(graffiti.express({
  schema: getSchema([A, B, C])
}));
app.listen(GRAPHQL_PORT, () => console.log(
  `GraphQL Server is now running on http://localhost:${GRAPHQL_PORT}`
));

@sibeliusseraphini I've got a fix for you. I don't have time right now to finish it, write tests, etc (having an oral exam on Monday). Can it wait until Monday, Tuesday?

@tothandras If you tell me in which file or a little more about this error, I can fork this repo and try to fix it and submit a PR

type.js line 196:

-        graphQLField.type = new GraphQLList(getType(graffitiModels, {name, description, fields}, newPath, rootType));
+        const fieldNameCapitalized = name.charAt(0).toUpperCase() + name.slice(1);
+        graphQLField.type = new GraphQLList(getType(graffitiModels, {name: `${graphQLType.name}${fieldNameCapitalized}`, description, fields}, newPath, rootType));

Although there is already a field name capitalisation somewhere in the file, you might create a function for that. Thank you!

thanks, I will try to figure it out
