Cannot load Fixture about sequelize-fixtures HOT 7 CLOSED

hi,

In data a model is referenced as LinkedServices, but its actually named LinkedService

Could provide a better error message for these cases, will update

from sequelize-fixtures.

The same error still persists when I change the line to:
LinkedServices: require("./app/models/linkedServices"),

I managed to make the exact same JSON work though by making it a module and exporting/importing it.

from sequelize-fixtures.

Hey @lawli3t, I'm currently having this same issue. Can you provide more insight into how you got this working? I have my test data setup with module.exports, but how did you import it? Thanks!

from sequelize-fixtures.

here is my snippet on importing it:

const models = require("./app/models");
const fixtures = require("./app/tests/data/sampledata")

var sequelize_fixtures = require("sequelize-fixtures"),
    modelDict = {
        User: require("./app/models/user"),
        // and so on .....
    };

models.sequelize.sync( {force:true} ).then(() => {
    sequelize_fixtures.loadFixtures(fixtures, models).then(function(){
        console.dir("Data created succesfully");
    });
});

from sequelize-fixtures.

I'm having the same issue. I even dumbed it down to just use a fixture that is a variable and I am still getting the Unhandled rejection TypeError: Cannot convert undefined or null to object error.

Any help would be greatly appreciated.

module.exports = function (sequelize, DataTypes) {
    return sequelize.define("foo", {
        propA: {type: DataTypes.STRING},
        propB: {type: DataTypes.INTEGER},
        status: {type: DataTypes.BOOLEAN}
    });
};

'use strict';

var sequelize_fixtures = require('sequelize-fixtures'),
    models = {
      Foo: require("../src/models/foo")
    };

var fixtures = [
  {
    model: 'Foo',
    data: {
      propA: 'bar',
      propB: 1
    }
  },
  {
    model: 'Foo',
    data: {
      propA: 'baz',
      propB: 3
    }
  }
];

sequelize_fixtures.loadFixtures(fixtures, models).then(function(){
  console.log('Complete!');
});

from sequelize-fixtures.

It finally dawned on me :)

You're passing a model factory function rather than a model.

module.exports = function (sequelize, DataTypes) { //this is a factory function, not a model
    return sequelize.define("foo", { //this produces the actual model
        propA: {type: DataTypes.STRING},
        propB: {type: DataTypes.INTEGER},
        status: {type: DataTypes.BOOLEAN}
    });
};

Instead you should import models/foo using sequelize.import(). See official example: https://github.com/sequelize/express-example/blob/master/models/index.js#L17

And your sequelize_fixtures call should look like this:

const models = require('../src/models');
sequelize_fixtures.loadFixtures(fixtures, models).then(function(){
  console.log('Complete!');
});

I released a tiny update with dac38bf that will detect this error and provide a helpful message.

I'm now thinking that sequelize-fixtures shoud ask for an instance of sequelize instead of a models map, to prevent this kind of confusion...

realised readme was kinda misleading too, updated
