私はCRUD操作を実行するためにexpress-cassandraを使用しています。サービスを実行し、Postmanを使用してAPIを作成すると、すべて正常に動作します。エラー「models.instance.QuestionnaireMasterはコンストラクタではありません」ノード-jのexpress-cassandra
しかし、chaiテストケースを使用して同じコントローラ関数を呼び出すと、 "models.instance.tableはコンストラクタではありません"というエラーが表示されます。続い
は、コードスニペットである：
dbClient.js：
"use strict";
module.exports = {
fields: {
id: {
type: "uuid",
default: { "$db_function": "uuid()" }
},
questionnaire_type: "varchar",
question: "varchar",
response_option: {
type: "list",
typeDef: "<varchar>"
},
owner_rolecode: "varchar",
is_active: "boolean",
created: {
type: "timestamp",
default: { "$db_function": "toTimestamp(now())" }
},
updated: {
type: "timestamp",
default: { "$db_function": "toTimestamp(now())" }
}
},
key: ["id"],
table_name: "questionnaire_master"
}var models = require('express-cassandra');
var settings = require('../../settings.js');
var config = settings.UserService.database.cql;
//Tell express-cassandra to use the models-directory, and
//use bind() to load the models using cassandra configurations.
models.setDirectory(__dirname).bind(
{
clientOptions: {
contactPoints: [config.host],
protocolOptions: { port: config.port },
keyspace: config.databaseName,
queryOptions: {consistency: models.consistencies.one}
},
ormOptions: {
//If your keyspace doesn't exist it will be created automatically
//using the default replication strategy provided here.
defaultReplicationStrategy : {
class: 'SimpleStrategy',
replication_factor: 1
},
migration: 'safe',
createKeyspace: true
}
},
function(err) {
if(err) console.log(err);
else console.log(models.timeuuid());
}
);
module.exports = models ;QuestionnaireMasterModel.jsと初期化接続
questionnaire_master.js：
var questionnaireMasterController = {};
var models = require('../models/dbCLient');
//var questionnaireMasterModel = require('../models/QuestionnaireMasterModel');
var responseEntity = require('../utility/response_entity');
questionnaireMasterController.createQuestionnaire = function (params, callback) {
\t var uuid = models.uuid();
\t var question = new models.instance.QuestionnaireMaster({
\t \t id : uuid,
\t \t questionnaire_type : params.questionnaire_type,
\t \t question: params.question,
\t \t response_option : params.response_option,
\t \t owner_rolecode : params.owner_rolecode, \t \t
\t \t is_active: true
\t });
\t question.save(function (err) {
\t \t if (err) {
\t \t \t if(err.name = 'apollo.model.validator.invalidvalue')
\t \t \t \t responseEntity.sendResponse(422, 'Invalid input paramters', null, {name : err.name, message : err.message},callback);
\t \t \t else
\t \t \t \t responseEntity.sendResponse(501, 'Error Occured', null, {name : err.name, message : err.message},callback);
\t \t \t console.log("err ::: ",err);
\t \t \t return;
\t \t }
\t \t responseEntity.sendResponse(201,"Question created successfully", { id: uuid }, null ,callback);
\t \t console.log('Yuppiie!');
\t }); \t
}
// User controller functions and expose it to app
module.exports = questionnaireMasterController;createQuestionnaire（新しいエントリを作成するコントローラ機能）APIが呼び出されたときに呼び出されます。正常に動作します。
questionnaire_master_test.js：私にエラーを与えてテストケース
var chai = require('chai');
var expect = chai.expect;
var chaiHttp = require('chai-http');
var randomstring = require("randomstring");
var questionnaireMasterController = require('../controller/questionnaire_master.js')
chai.use(chaiHttp);
var supertest = require('supertest');
describe('Check for create Patient', function() {
it('Should create a new question in questionnaire master table', function (done) {
var question = {
"questionnaire_type": "Select one",
"question": "This is dummy question",
"response_option": ["dummyoption1", "dummyoption2"],
"owner_rolecode": "01",
"is_active": true
};
questionnaireMasterController.createQuestionnaire(question, function (result) {
JSON.stringify(result);
expect(result.code).to.be.a('number').eq(201);
done();
});
});
});createQuestionnaireは（）を再度questionnaire_master_test.jsから呼び出されます。
