AirBnB clone - The Console

Storage • Console • Execution • Tests

Description

This project is the first version of the AirBnB project, which is an AirBnB clone that includes design, layout, infrastructure and database. In this repository you will find the AirBnB console, which executes specific commands (shown below) to make specific actions.

Code Style

Pycodestyle was taken into account and implemented for all files.

Storage

The FileStorage class is in charge of managing the storage through a JSON file (file.json), the instances are created, updated or deleted, all this through a FileStorage instance called storage.

Console

The console is used to manage the storage of class instances (file.json), this console can be used and executed in two ways, which are interactive and non-interactive mode.

The following table shows all the commands for storage management and explains how to use them by its format:

Command	Description	Format
help	Shows all allowed commands or gives information about a specific command.	`help` / `help <command>`
quit or EOF	Exits the program.	`quit`
create	Creates a new instance.	`create <classname>`
show	Shows a specific instance by its `classname` and its `id`.	`show <classname> <id>`
all	Displays all stored instances or all stored instances of a specific class by its `classname`.	`all` / `all <classname>`
update	Updates an instance (adds or modifies attributes) by its `classname`, `id`, `attribute` and its `value` to add/modify.	`update <classname> <id> <attribute> <attrvalue>`
destroy	Deletes an instance by its `classname` and its `id`.	`destroy <classname> <id>`

Execution

Interactive mode

$ ./console.py
(hbnb) help
Documented commands (type help <topic>):
========================================
EOF  all  create  destroy  help  quit  show  update
(hbnb)
(hbnb)
(hbnb) quit
$

Non-Interactive Mode

$ echo "help" | ./console.py
(hbnb)
Documented commands (type help <topic>):
========================================
EOF  all  create  destroy  help  quit  show  update
(hbnb)
$
$ cat test_help
help
$
$ cat test_help | ./console.py
(hbnb)
Documented commands (type help <topic>):
========================================
EOF  all  create  destroy  help  quit  show  update
(hbnb)
$

Examples using the Hbnb console

Console execution and help command implementation to get information about quit command:

Create, update and show command implementation to create and display a new instance:

Create, destroy and all command implementation to display how the destroy command works:

Tests

Tests were developed and implemented for all the classes of the project using unittest in a different test environment, in order not to modify the JSON storage working with a file named test_file.json, which at the end of the tests will be deleted. All tests are in this directory.

To test the classes built in this project this command can be executed:

python3 -m unittest discover tests

To execute a specific test, the next command can be run with the specific path, as it is shown:

python3 -m unittest tests/test_models/test_base_model.py
