permissions-system 0.2.3

Alternative to admin utilities for more autonomy, targeted towards FastAPI.

Permissions Systems

It's plugin for fastapi (but can be used with similar frameworks) any frameworks, that provides a minimal

setup for maintaining resources and related permissions for user-groups.

How to use it?

application.py

from fastapi import FastAPI
import databases
import sqlalchemy
import os
from permissions_system.PermissionsSystemDatabases import PermissionsS

app = FastAPI()

DB_URI = os.environ["DB_URI"]

database = databases.Database(DB_URI)
metadata = sqlalchemy.MetaData()
ps = PermissionsS(metadata, database, DB_URI)


app.add_event_handler("startup", startup)
app.add_event_handler("shutdown", shutdown)

async def startup():
    await database.connect()
    ps.setup()

for Flask app you will call ps.setup() after db.init(app), assuming you are using flask_sqlalchemy

Step1 - instantiate PermissionsS class.

Step2 - during startup event after database is connected make a call to setup() ************_************

_PermissionsS will then detect your tables add them to resources, add super-admin user-group, if there isn't already one. Everytime there is a new resource that gets added automatically to resources table. User-group super-admin by default has all CRUD permissions for all resources. To add a new user-group and related permissions use built-in functions add_user_group and add_permissions. To get whether a particular user has CRUD permissions for a particular resource you will call > ps.user_has_permissions(user_id:UUID,resource:str,permission_type:PermissionTypesEnum) -> bool*

PermissionsSystem is not like django-admin or flask-admin. It doesn't provide a front-end admin dashboard, but a minimal setup to manage resources and permissions. It aims to provide autonomy and more control over to the developer. For front-end you will end up using something more custom or React-admin or vue-element-admin

PermissionsSystem now only uses sqlalchemy and is completely sync.
