Calling populate() gets TypeError: Cannot read property 'sync' of undefined

[mblackritter]

I'm just setting up jsonapi-server to mock our JSON:API, but while I try to populate the DB, I get the following error:

/aniola-cotesco-se/node_modules/jsonapi-store-relationaldb/lib/sqlHandler.js:105
      self.baseModel.sync(options).asCallback(cb)
                    ^

TypeError: Cannot read property 'sync' of undefined

I kept my resource file very simple and already tried to remove the attributes, but that doesn't make a difference:

jsonApi.define({
  namespace: 'json:api',
  resource: 'settings',
  handlers: dbHandler,
  attributes: {
    title: jsonApi.Joi.string().required()
      .description('The articles title, should be between 8 and 15 words')
      .example('Learning how to use JSON:API'),
    content: jsonApi.Joi.string().required()
      .description('The main body of the article, provided as HTML')
      .example('<p>Paragraph 1. Lovely.</p><hr /><p>The End.</p>'),
    created: jsonApi.Joi.string().regex(/^[12]\d\d\d-[01]\d-[0123]\d$/)
      .description('The date on which the article was created, YYYY-MM-DD')
      .example('2017-05-01'),
    status: jsonApi.Joi.string().default('published')
      .description('The status of the article - draft, ready, published')
      .example('published'),
    views: jsonApi.Joi.number().default(0)
      .description('Number of views for this article')
  }
})

What might it be that I'm not aware of? 🤗

Your error is unexpected. I'll try to reproduce it locally to gain more insight.

I also have this issue, node version doesn't seem to make a difference

I bumped into this. Looking at the source I discovered that you can only call populate() after you called jsonApi.start().

I also have this problem, is there any solution already?

Thank to vnen I think I figured this out. Kind of stupid:

You cann't populate the database directly after creating the handler.

Call handler.populate after defining the database resource. In my case:

'use strict';

const jsonApi = require('jsonapi-server');

const handler = require('../handlers/handler');

jsonApi.define({
  resource: "userCourseHighscore",
  handlers: handler,
  attributes: {
    userId: jsonApi.Joi.string(),
    courseId: jsonApi.Joi.string(),
    score: jsonApi.Joi.number(),
    createdAt: jsonApi.Joi.date(),
    updatedAt: jsonApi.Joi.date()
  }
});

handler.populate();
