Question: error when implementing new rest datasource

mindaugasnakrosis commented 5 years ago

I try implementing rest datasource in color CRUD example instead of memory datasource.

datasources/rest.datasource.js

const config = {
  "name": "rest",
  "connector": "rest",
  "options": {
    "headers": {
      "accept": "application/json",
      "content-type": "application/json"
    },
  },
  "operations": [
    {
      "template": {
        "method": "GET",
        "url": "http://127.0.0.1:8529/api",
        "query": {
          "query": "{query}"
        },
        "responsePath": "$.results[0]"
      }
    }
  ]
};
exports.RestDataSource = datasourceFactory('rest', config);

datasources/index.js exports.RestDataSource = require('./rest.datasource');

color.repository.js

exports.ColorRepository = repositoryFactory({
  modelName: 'color',
  datasourceName: 'rest',
});

While executing find query I get an error:

Unhandled error in GET /color: 500 TypeError: this.modelClass.find is not a function
