Yii 2 JustCoded Project Template

Yii 2 JustCoded Project Template is a skeleton Yii 2 application best for rapidly creating projects with admin interface and RBAC.

The template contains the basic features including contact page, user login/logout, admin panel with users management, route-based RBAC access control, fixture examples. It includes all commonly used configurations that would allow you to focus on adding new features to your application.

DIRECTORY STRUCTURE

  app/                contains your application classes and files
    |-- assets           css/js assets and AssetBundle classes
    |-- base             base classes (overwrite yii\base or few more) 
    |-- components       application "components" classes 
    |-- console          controllers for console commands
    |-- controllers      controllers for web application
    |-- filters          application filters (similar to yii\filters) 
    |-- forms            various form models 
    |-- mail             view files for e-mails 
    |-- models           ActiveRecord model classes 
    |-- modules          connected modules, admin panel module by default
    |-- rbac             RBAC Manager / components 
    |-- traits           global traits, grouped by type 
    |-- views            view files for the Web application
    |-- widgets          application widgets to use inside views 
  config/             contains application configurations
  database/           contains migration and fixtures
  tests/              contains various tests for the basic application
  vendor/             contains dependent 3rd-party packages
  public/             contains public assets and web entry script index.php / server docroot

The difference from Yii2 basic template:

• Improved IDE support for custom components (Yii::$app->getComponent(...))
• Application code is moved to it's own folder /app
• Config files are moved outside application code folder and use .env extension (ability to get values from server ENV variables or .env file)
• commands folder is renamed to console (because inside we actually have Controllers, not Commands).
• Form models have their own folder to separate them from ActiveRecord models
• assets folder is used to store public assets as well (to be able to publish assets in the same way for app / modules / widgets)
• Admin module with CRUD example (Users management)
• Advanced RBAC based on 4 default roles and route-based access control. See justcoded/yii2-rbac
• Application params replaced with settings extensions (IDE autocompletion available). See justcoded/yii2-settings

REQUIREMENTS

The minimum requirement by this project template that your Web server supports PHP 7.0.

INSTALLATION

Install via Composer

If you do not have Composer, you may install it by following the instructions at getcomposer.org.

You can then install this project template using the following command:

php composer.phar create-project --prefer-dist justcoded/yii2-starter my-project

or

composer create-project --prefer-dist justcoded/yii2-starter my-project

CONFIGURATION

ENV support

Config files are the same for all environments. You don't need to create some "local" config files. Instead you can accept different parameters from server environment with env() helper function.

Server environment variables can be set through web server vhost configuration, .htaccess file, or .env file in project root (the simplest option).

To start using the project template copy .env.example as .env in the project root and setup it.

Web

Copy /public/.htaccess.example as /public/.htaccess to enable pretty URLs support and cache/expire tokens required by Google PageSpeed Insights test.

Furthermore you should check such options inside .env:

APP_ENV=dev
APP_DEBUG=true
APP_KEY=wUZvVVKJyHFGDB9qK_Lop4QE1vwb4bYU

*APP_KEY is used as CSRF token (cookie verification key). In order to set or change it, run:

php yii security/app-key

Database

You should update your .env file config:

DB_HOST=127.0.0.1
DB_NAME=yii2_starter
DB_USER=root
DB_PASS=12345

NOTES:

• Yii won't create the database for you, this has to be done manually before you can access it.
• By default starter configured to work with MySQL database. If you want to use another database you need to configure dsn string inside config/db.php (or define env variable like DB_DSN="mysql:host={host};dbname={dbname}").

LAUNCH

You will need to create required tables through migrations and init RBAC extension. Launch the commands below from terminal:

php yii migrate
php yii fixture/load User
php yii rbac/init
php yii rbac/assign-master 1
php yii rbac/scan
php yii rbac/scan --path=@vendor/justcoded/yii2-rbac/ --routesBase=admin/rbac/

Now you should be able to access the application through the following URL, assuming my-project is the directory directly under the Web root.

http://localhost/my-project/public/

Or you can run yii serve to launch Yii built-in web server, similar to usual Yii basic application.

Admin panel can be accessible only after login. If you used fixtures to fill the database with dummy content, then admin panel access will be:

http://localhost/my-project/public/admin/
User:       [email protected]
Password:   password_0

TESTING

Tests are located in tests directory. They are developed with Codeception PHP Testing Framework. By default there are 3 test suites:

• unit
• functional
• acceptance

Tests can be executed by running

vendor/bin/codecept run

The command above will execute unit and functional tests. Unit tests are testing the system components, while functional tests are for testing user interaction. Acceptance tests are disabled by default as they require additional setup since they perform testing in real browser.

Running acceptance tests

To execute acceptance tests do the following:

1. Rename tests/acceptance.suite.yml.example to tests/acceptance.suite.yml to enable suite configuration

2. Replace codeception/base package in composer.json with codeception/codeception to install full featured version of Codeception

3. Update dependencies with Composer

   composer update  
   

4. Download Selenium Server and launch it:

   java -jar ~/selenium-server-standalone-x.xx.x.jar
   

   In case of using Selenium Server 3.0 with Firefox browser since v48 or Google Chrome since v53 you must download GeckoDriver or ChromeDriver and launch Selenium with it:

   # for Firefox
   java -jar -Dwebdriver.gecko.driver=~/geckodriver ~/selenium-server-standalone-3.xx.x.jar
   
   # for Google Chrome
   java -jar -Dwebdriver.chrome.driver=~/chromedriver ~/selenium-server-standalone-3.xx.x.jar
   

   As an alternative way you can use already configured Docker container with older versions of Selenium and Firefox:

   docker run --net=host selenium/standalone-firefox:2.53.0
   

5. (Optional) Create yii2_basic_tests database and update it by applying migrations if you have them.

   tests/bin/yii migrate
   

   The database configuration can be found at config/test_db.php.

6. Start web server:

   tests/bin/yii serve
   

7. Now you can run all available tests

   # run all available tests
   vendor/bin/codecept run
   
   # run acceptance tests
   vendor/bin/codecept run acceptance
   
   # run only unit and functional tests
   vendor/bin/codecept run unit,functional
   

Code coverage support

By default, code coverage is disabled in codeception.yml configuration file, you should uncomment needed rows to be able to collect code coverage. You can run your tests and collect coverage with the following command:

#collect coverage for all tests
vendor/bin/codecept run -- --coverage-html --coverage-xml

#collect coverage only for unit tests
vendor/bin/codecept run unit -- --coverage-html --coverage-xml

#collect coverage for unit and functional tests
vendor/bin/codecept run functional,unit -- --coverage-html --coverage-xml

You can see code coverage output under the tests/_output directory.
