How to implement memcached with django with examples

Install Memcached

Memcached is an open source, high-performance, distributed memory object caching system. It is used to speed up dynamic web applications by alleviating database load. In order to use Memcached with Django, you must first install it on your server. This tutorial will walk you through the steps of installing Memcached on a Linux server.

The first step is to install the Memcached package. On Ubuntu, you can do this by running the following command:

sudo apt-get install memcached

Once the package is installed, you can start the Memcached service by running the following command:

sudo service memcached start

You can also configure the Memcached service to start automatically when the server boots up. To do this, run the following command:

sudo update-rc.d memcached defaults

You can also configure the Memcached service to listen on a specific IP address and port. To do this, edit the /etc/memcached.conf file and add the following line:

-l :

Once you have installed and configured the Memcached service, you can move on to the next step of installing the Python Memcached library.

Configure Memcached

Memcached is a distributed memory caching system that can be used to speed up dynamic web applications. It is used to store data in memory for quick access. To configure Memcached, you need to edit the configuration file. The configuration file is usually located in the /etc/memcached.conf directory. In the configuration file, you can set the port, memory size, and other settings. You can also set the maximum number of connections and the maximum number of objects that can be stored in the cache. To make changes to the configuration file, you can use a text editor such as vi or nano.

Once you have edited the configuration file, you need to restart the Memcached service. To do this, you can use the command sudo service memcached restart. This will restart the Memcached service and apply the changes you have made to the configuration file. After restarting the service, you can check the status of the service by using the command sudo service memcached status.

Install the Python Memcached Library

In order to use Memcached with Django, you need to install the Python Memcached library. This library provides an interface for communicating with Memcached servers. To install the library, you can use the pip command. For example, if you are using Python 3, you can run the following command:

pip3 install python-memcached

Once the library is installed, you can use it in your Django code. To do this, you need to import the library and create a connection to the Memcached server. For example, you can use the following code to create a connection:

import memcache

mc = memcache.Client(['127.0.0.1:11211'], debug=0)

The mc variable now contains a connection to the Memcached server. You can use this connection to store and retrieve data from the server. For more information on how to use the library, you can refer to the official documentation.

Configure Django

Django is a powerful web framework that can be used to create web applications. To use Memcached with Django, you need to configure Django to use the Memcached library. This tutorial will show you how to configure Django to use Memcached.

First, you need to install the Python Memcached library. This library provides an interface for Django to interact with Memcached. To install the library, you can use the pip command:

pip install python-memcached

Once the library is installed, you need to configure Django to use it. To do this, you need to add the following lines to your settings.py file:

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': '127.0.0.1:11211',
    }
}

The LOCATION parameter specifies the address and port of the Memcached server. You can find more information about configuring Django to use Memcached in the Django documentation.

Once you have configured Django to use Memcached, you can start using it in your code. To do this, you need to use the cache object provided by Django. This object provides methods for interacting with Memcached. For example, you can use the set() method to store data in Memcached:

cache.set('key', 'value')

You can find more information about using Memcached with Django in the Django documentation.

Use Memcached in Your Code

Using Memcached with Django is easy and straightforward. To use Memcached in your code, you need to install the Python Memcached library and configure Django to use it. Once you have done that, you can use the Memcached library in your code to store and retrieve data from the cache. Here is an example of how to use Memcached in your code:

import memcache

# Create a memcache client
mc = memcache.Client(['127.0.0.1:11211'])

# Set a value in the cache
mc.set('my_key', 'my_value')

# Get a value from the cache
value = mc.get('my_key')

# Delete a value from the cache
mc.delete('my_key')

For more information on how to use Memcached with Django, please refer to the official Django documentation.
