# Python Cache PostgreSQL Adapter

[![Test and Analysis](https://github.com/othercodes/python-cache-postgresql-adapter/actions/workflows/test.yml/badge.svg)](https://github.com/othercodes/python-cache-postgresql-adapter/actions/workflows/test.yml)

Provides a PostgreSQL implementation of the Cache Interface for Python.

## Installation

The easiest way to install the Cache PostgreSQL Adapter is to get the latest version from PyPI:

```bash

# using poetry

poetry add rndi-cache-postgresql-adapter

# using pip

pip install rndi-cache-postgresql-adapter

```

## The Contract

The used interface is `rndi.cache.contracts.Cache`.

## The Adapter

Just initialize the class you want and use the public methods:

```python

from rndi.cache.contracts import Cache

from rndi.cache.adapters.postgresql.adapter import PostgreSQLCacheAdapter

def some_process_that_requires_cache(cache: Cache):

    # retrieve the data from cache, ir the key is not cached yet and the default 

    # value is a callable the cache will use it to compute and cache the value

    user = cache.get('user-id', lambda: db_get_user('user-id'))

    print(user)

# inject the desired cache adapter.

cache = PostgreSQLCacheAdapter(

    'localhost',

    'database_name',

    'username', 

    'password', 

    ttl=900, # optional

    port=5432 # optional

)

some_process_that_requires_cache(cache)

```
