This repository contains the third stage of a student project to build a clone of the AirBnB website. This stage implements a MySQL database storage to manage program data by transitioning from the file storage initially used in the initial stage using object relational mapping to switch between the realational database and file storage.
Tasks | Files | Description |

1: Pep8 | N/A | All code is pep8 compliant |
2: Unit Testing | /tests | All class-defining modules are unittested |
3. Make BaseModel | /models/base_model.py | Defines a parent class to be inherited by all model classes |
4. Update BaseModel w/ kwargs | /models/base_model.py | Add functionality to recreate an instance of a class from a dictionary representation |
5. Create FileStorage class | /models/engine/file_storage.py /models/_ init _.py /models/base_model.py | Defines a class to manage persistent file storage system |
6. Console 0.0.1 | console.py | Add basic functionality to console program, allowing it to quit, handle empty lines and ^D |
7. Console 0.1 | console.py | Update the console with methods allowing the user to create, destroy, show, and update stored data |
8. Create User class | console.py /models/engine/file_storage.py /models/user.py | Dynamically implements a user class |
9. More Classes | /models/user.py /models/place.py /models/city.py /models/amenity.py /models/state.py /models/review.py | Dynamically implements more classes |
10. Console 1.0 | console.py /models/engine/file_storage.py | Update the console and file storage system to work dynamically with all classes update file storage |
-
First clone this repository.
-
Once the repository is cloned locate the "console.py" file and run it as follows:
/AirBnB_clone$ ./console.py
- When this command is run the following prompt should appear:
(hbnb)
- This prompt designates you are in the "HBnB" console. There are a variety of commands available within the console program.
* create - Creates an instance based on given class
* destroy - Destroys an object based on class and UUID
* show - Shows an object based on class and UUID
* all - Shows all objects the program has access to, or all objects of a given class
* update - Updates existing attributes an object based on class name and UUID
* quit - Exits the program (EOF will as well)
Users are able to issue a number of console command using an alternative syntax:
Usage: <class_name>.<command>([<id>[name_arg value_arg]|[kwargs]])
Advanced syntax is implemented for the following commands:
* all - Shows all objects the program has access to, or all objects of a given class
* count - Return number of object instances by class
* show - Shows an object based on class and UUID
* destroy - Destroys an object based on class and UUID
* update - Updates existing attributes an object based on class name and UUID
