PyMongo Adapter is the [PyMongo](https://pypi.org/project/pymongo/) adapter for [PyCasbin](https://github.com/casbin/pycasbin). With this library, Casbin can load policy from MongoDB or save policy to it.

This adapter supports both synchronous and asynchronous PyMongo APIs.

## Installation

```

pip install casbin_pymongo_adapter

```

## Simple Example

```python

import casbin_pymongo_adapter

import casbin

adapter = casbin_pymongo_adapter.Adapter('mongodb://localhost:27017/', "dbname")

e = casbin.Enforcer('path/to/model.conf', adapter, True)

sub = "alice"  # the user that wants to access a resource.

obj = "data1"  # the resource that is going to be accessed.

act = "read"  # the operation that the user performs on the resource.

if e.enforce(sub, obj, act):

    # permit alice to read data1casbin_sqlalchemy_adapter

    pass

else:

    # deny the request, show an error

    pass

# define filter conditions

from casbin_pymongo_adapter import Filter

filter = Filter()

filter.ptype = ["p"]

filter.v0 = ["alice"]

# support MongoDB native query

filter.raw_query = {

    "ptype": "p",

    "v0": {

        "$in": ["alice"]

    }

}

# In this case, load only policies with sub value alice

e.load_filtered_policy(filter)

```

## Async Example

```python

from casbin_pymongo_adapter.asynchronous import Adapter

import casbin

adapter = Adapter('mongodb://localhost:27017/', "dbname")

e = casbin.AsyncEnforcer('path/to/model.conf', adapter)

# Note: AsyncEnforcer does not automatically load policies.

# You need to call load_policy() manually.

await e.load_policy()

```
