Examples

Some basic examples on how to user FastJson-db

Creating a Class

To manipulate JsonTables, you need to create a JsonModel subclass (dataclass), so the JsonTable only accepts that especific JsonModel subclass.

from fastjson_db import JsonModel
from dataclasses import dataclass

@dataclass
class User(JsonModel):
    _id: int
    name: str = ""
    password: str = ""

It's obrigatory using _id field or it will not result in error when quering.

Creating a JsonTable

JsonTables are the ones inserting and updating your dataclasses in .json files. They will automaticly create and facilitate the usage of .json "tables", trying to simulate a simple database.

from fastjson_db import JsonModel, JsonTable
from dataclasses import dataclass

@dataclass
class User(JsonModel):
    _id: int = 0
    name: str = ""
    password: str = ""
    
user = User(name="Allan", password="123")

user_table = JsonTable("users.json", User)
