AirBnB Clone: Phase # 3 : API with Swagger
Description Project attempts to clone the the AirBnB application and website, including the database, storage, RESTful API, Web Framework, and Front End. Currently the application is designed to run with 2 storage engine models:
File Storage Engine:
/models/engine/file_storage.py Database Storage Engine:
/models/engine/db_storage.py
To Setup the DataBase for testing and development, there are 2 setup scripts that setup a database with certain privileges: setup_mysql_test.sql & setup_mysql_test.sql (for more on setup, see below).
The Database uses Environmental Variables for tests. To execute tests with the environmental variables prepend these declarations to the execution command:
$ HBNB_MYSQL_USER=hbnb_test HBNB_MYSQL_PWD=hbnb_test_pwd
HBNB_MYSQL_HOST=localhost HBNB_MYSQL_DB=hbnb_test_db HBNB_TYPE_STORAGE=db
[COMMAND HERE]
Environment
OS: Ubuntu 14.04 LTS
language: Python 3.4.3
web server: nginx/1.4.6
application server: Flask 0.12.2, Jinja2 2.9.6
web server gateway: gunicorn (version 19.7.1)
database: mysql Ver 14.14 Distrib 5.7.18
documentation: Swagger (flasgger==0.6.6)
style:
python: PEP 8 (v. 1.7.0)
web static: W3C Validator
bash: ShellCheck 0.3.3
Configuration Files The /config/ directory contains configuration files for nginx and the Upstart scripts. The nginx configuration file is for the configuration file in the path: /etc/nginx/sites-available/default. The enabled site is a sym link to that configuration file. The upstart script should be saved in the path: /etc/init/[FILE_NAME.conf]. To begin this service, execute:
$ sudo start airbnb.conf This script's main task is to execute the following gunicorn command:
$ gunicorn --bind 127.0.0.1:8001 wsgi.wsgi:web_flask.app The gunicorn command starts an instance of a Flask Application.
Web Server Gateway Interface (WSGI) All integration with gunicorn occurs with Upstart .conf files. The python code for the WSGI is listed in the /wsgi/ directory. These python files run the designated Flask Application.
Setup This project comes with various setup scripts to support automation, especially during maintanence or to scale the entire project. The following files are the setupfiles along with a brief explanation:
dev/setup.sql: Drops test and dev databases, and then reinitializes the datbase.
Usage: $ cat dev/setup.sql | mysql -uroot -p setup_mysql_dev.sql: initialiezs dev database with mysql for testing
Usage: $ cat setup_mysql_dev.sql | mysql -uroot -p setup_mysql_test.sql: initializes test database with mysql for testing
Usage: $ cat setup_mysql_test.sql | mysql -uroot -p 0-setup_web_static.sh: sets up nginx web server config file & the file structure.
Usage: $ sudo ./0-setup_web_static.sh 3-deploy_web_static.py: uses 2 functions from (1-pack_web_static.py & 2-do_deploy_web_static.py) that use the fabric3 python integration, to create a .tgz file on local host of all the local web static fils, and then calls the other function to deploy the compressed web static files. Command must be executed from the AirBnB_clone root directory.
Usage: $ fab -f 3-deploy_web_static.py deploy -i ~/.ssh/holberton -u ubuntu Testing unittest This project uses python library, unittest to run tests on all python files. All unittests are in the ./tests directory with the command:
File Storage Engine Model:
$ python3 -m unittest discover -v ./tests/ DataBase Storage Engine Model
$ HBNB_MYSQL_USER=hbnb_test HBNB_MYSQL_PWD=hbnb_test_pwd
HBNB_MYSQL_HOST=localhost HBNB_MYSQL_DB=hbnb_test_db HBNB_TYPE_STORAGE=db
python3 -m unittest discover -v ./tests/
All Tests
The bash script init_test.sh executes all these tests for both File Storage & DataBase Engine Models:
checks pep8 style
runs all unittests
runs all w3c_validator tests
cleans up all pycache directories and the storage file, file.json
Usage init_test.sh:
$ ./dev/init_test.sh
CLI Interactive Tests
This project uses python library, cmd to run tests in an interactive command line interface. To begin tests with the CLI, run this script:
File Storage Engine Model
$ ./console.py
To execute the CLI using the Database Storage Engine Model:
$ HBNB_MYSQL_USER=hbnb_test HBNB_MYSQL_PWD=hbnb_test_pwd
HBNB_MYSQL_HOST=localhost HBNB_MYSQL_DB=hbnb_test_db HBNB_TYPE_STORAGE=db
./console.py
For a detailed description of all tests, run these commands in the CLI:
(hbnb) help help
List available commands with "help" or detailed help with "help cmd".
(hbnb) help
Amenity City Place State airbnb create help show BaseModel EOF Review User all destroy quit update
(hbnb) help User class method with .function() syntax Usage: User.() (hbnb) help create create: create [ARG] [PARAM 1] [PARAM 2] ... ARG = Class Name PARAM = = value syntax: "" SYNOPSIS: Creates a new instance of the Class from given input ARG and PARAMS. Key in PARAM = an instance attribute. EXAMPLE: create City name="Chicago" City.create(name="Chicago") Tests in the CLI may also be executed with this syntax:
destroy: .destroy()
update: .update(, , )
update with dictionary: .update(, )
