Django API

 

Give your Django app an API with only a single line of code

 

It's an incredibly easy method of adding serialization to any page of your Django app. Whereas the wonderful Django-REST-Framework provides everything you need to make a "complete" API for your site, it's fairly complicated and takes a good deal time to set up. Django-Easy-API has very a different philosophy: every page should be serializable, and it should be incredibly easy to set up.

That's why with Django-Easy-API, you can give your whole site an API with only a single line of code!

 

Django Track User Activity

 

Django: Find Most Recently Logged in Users

 

Do you want to find the most recently logged in users in your Django application? Cool, no problem. You'll be filtering and sorting your most active users in no time. Here's how you do it:

 

Django Debugging

 

Debugging Django with a Threaded Pdb

 

Need to debug a Django website or API that you're building, but don't want to disrupt service for other developers or clients using your app? Well then, you're in luck, because this tip is for you!

If you don't know already, the python debugger, aka pdb, is the best tool ever. Just call pdb.set_trace() in your python apps and get an interactive shell wherever you want.

 

Django Template Tags

 

A Placeholder Template Tag for Django

 

Here's how to make a crude template tag which lets you add the HTML5 'placeholder' attribute to your form field inputs and text areas in a Django template.

 

Django Debugging Toolbar

 

Debugging SQL with the Django-debug-toolbar

 

How often have you written queries using the Django ORM, just to forget about them a second later as soon as you get the results you're looking for? Even if you do drop down to writing SQL, it's still easy to forget that down the road certain queries can have a negative performance impact on your project.

Fortunately, the Django-debug-toolbar can be used to identify processes that take up the most time when rendering a certain page.

 

Django Models

 

Advanced Django Models: Improve Your Python Development

 

Models are a core concept of the Django framework. According to Django’s design philosophies for models, we should be as explicit as possible with the naming and functionality of our fields, and ensure that we’re including all relevant functionality related to our model in the model itself, rather than in the views or somewhere else. If you’ve worked with Ruby on Rails before, these design philosophies won’t seem new as both Rails and Django implement the Active Record pattern for their object-relational mapping (ORM) systems to handle stored data.

 

Django Timezones

 

Introducing Django-Easy-Timezones

 

For some reason, back when the language of the web was still being solidified, people forgot about timezones. The W3C remembered that not everybody speaks English, so they included the 'Accept-Language' HTTP Header, but apparently they never considered that users might not be in the same timezone as their server, so they forgot to include an 'Accept-Timezone' header. Since then, all web developers have been had the responsibility for figuring out the timezones of their users, rather than allowing their clients to do it automatically. This has resulted in a lot of horrible user experiences and misprinted time information over the years.

 

Django for Non Programmers

 

Setting up a Django Project for the Non-Programmer

 

This tutorial answers the question, "How do I setup a Django project from scratch?". Since you're reading this, I assume (I hope, at least) you know that Django is a Python web framework built for rapid web development. We'll go through the setup process on both Windows and Unix environments, detailing the basic installation procedures of Django v1.5 and the dependencies required as well as a few additional libraries/extensions to get you started developing ASAP.

 

Dokku Django

 

Deploying a Django App on Dokku

 

Dokku is a "Docker powered mini-Heroku" that you can deploy on your own server to serve as your own private PaaS.

Why would you want your own mini-Heroku? Well, Heroku can cost money, it's hosted in the cloud and you may not want your application to leave the room just yet, it doesn't support WebSockets or long-polling, you don't have 100% control over all aspects of the platform and/or maybe you're just the DIY kind of person.

 

Django Project Management

 

How to take on a large Django project

 

Moving from smaller projects with only a few apps to complex larger projects is difficult to do. In most cases, you have to get your hands dirty, work on a few bug fixes to familiarize yourself with the codebase. Before that though, it's important to set the proper groundwork by establishing expectations with the client and analyzing the code from a higher level.

When approaching a project, focus on the following areas to quickly get up to speed with the codebase and determine the unknowns.

 

 

Django Sites

 

How to Install Multiple Django Sites on the Same Server

 

This is a short and technical post about deploying two or more Django applications on the same server, so that 'http://yourdomain.com/' and 'http://yourdomain.com/otherapp' access two different Django projects.

 

Django Profiling

 

Faster Django Profiling

 

As our search results are now rendered on the client-side rather than on the server, we had to write a whole new API to get the data into the client. Once we had written it, we found that it was far slower than what we considered to be acceptable - results were averaging at 1.7s - and we shoot for sub 200ms response times. Not good! But what was going wrong? Why was Django being so slow? It actually wasn't easy to see immediately, and the normally wonderful Django Debug Toolbar wasn't any use as it doesn't work on AJAX requests.

 

Django Dictionary in Template

 

How to List Items In A Dictionary in A Django Template

 

Here's a quick tutorial on how to iterate over a dictionary in a Django template. We get asked this quite a lot so we figured we'd put it online in case anybody is Googling it.
