How to create loopback component with PersistedModel?

[Rastio Hodul]

Hi,

I'm trying to create a loopback component that would have a PersistedModel.

Trying to do the same as loopback-component-oauth2, but models are not migrated to DB.

They do show up in loopback explorer but any call to GET results in:

"Cannot call Postcard.find(). The find method has not been setup. The PersistedModel has not been correctly attached to a DataSource!",

Here is my code in component's index.js:

'use strict';

var loopback = require('loopback');

var DataModel = loopback.PersistedModel || loopback.DataModel;

function loadModel(jsonFile) {

    var modelDefinition = require(jsonFile);

    return DataModel.extend(modelDefinition.name,

        modelDefinition.properties,

        {

            relations: modelDefinition.relations,

        });

}

module.exports = function (app, options) {

    var PostcardModel = loadModel('./models/postcard.json');

    var Postcard = require('./models/postcard.js')(PostcardModel);

    Postcard.dataSource = app.datasources.db;

    Postcard.public = true ;

    app.model(Postcard);

};

Are there any guidelines to do this?

Thanks.

Figured it out. This is important part:

    app.model(Postcard, {

        'dataSource': 'db',

        'public': true,

    });
