I’m hoping to write a quick tutorial to get you started using Angular with Django What it turned into was a tutorial fueled by Red Bull.
My apologies if it gets sloppy towards the end! Having read posts on the subject of using Django and Angular together, I felt most were reinventing the wheel, so to speak. Although the example code I have given is crude it should highlight how I've been using them on projects. Introduction to Django Selenium Testing.
Posted by Marco in Code, Django If you’ve never heard of Selenium, put simply, it’s a tool that allows you to create tests that are run in the browser and interact with your UI in the same way as if you were manually testing your website or app.
It’s the de-facto standard to test complex Web UI interactions that usually involve a heavy use of JavaScript, and that’s probably the main use-case for it. Other than that, we also use it sometimes as a helper tool for cross-browser design (CSS) testing by running Selenium tests through different browsers and taking screenshots or recording videos. Selenium’s been around for a long time now, and is available in various programming languages, but up until Django 1.4 came along you couldn’t have your Selenium tests (easily) integrated with your Django test suite.
Since then, a new class named LiveServerTestCase, that your Selenium test classes can inherit from, was introduced. Installation.

Python - Django creating a form field that's read only using widgets. Custom Widget Types for HTML5 Form Fields. Django/Ember Token Authentication. Authentication can be a real headache.
Thankfully, Django REST Framework and Ember have taken care of the heavy-lifting already. As I’ve previously detailed, implementing session-based authentication with Django and Ember is not as hard as you might think. Now I’d like to say the same thing for token-based authentication. In token-based authentication, every user in the database is assigned a unique token. The flow of authentication then works like this: You send a username and password to the APIThe API validates the credentials and returns that user’s tokenYou include the token in the header of every request going forward to prove that you are already authenticated.
HTML5 and Django Form Inputs - Bryan Pieper's Blog. I recently went through the fairly painless of process of upgrading thepiepers.net to html5.
This will allow me more flexibility in the future as more browsers expand their support for html5. In addition, html5 has a number of improvements over html4 that will make my front-end work a little easier. In the process of upgrading the site, I implemented the following Internet Explorer overrides for html5 elementsFixed display issues for non-html5 elementsImplemented Django html5 form inputs With any front-end update to your site, there is always the Internet Explorer factor. Finally, the Django form inputs do not support the new input types like “email”, “tel” and “url”, just to name a few. From django.forms.widgets import Inputfrom django import forms class Html5EmailInput(Input): input_type = 'email' class Html5URLInput(Input): input_type = 'url'... class Html5Form(forms.Form): email = forms.CharField(widget=Html5EmailInput()) url = forms.CharField(widget=Html5URLInput())... Adding search to a Django site in a snap.
Search is a feature that is — or at least, should be — present on most sites containing dynamic or large content. There are a few projects around to tackle that. Here’s a non-exhaustive list: djangosearch, django-search (with a dash), django-sphinx. Those search engines are great, but they seem like overkill if you just need a simple search feature for your CMS or blog. Front end admin toolbar. Searchengine. This tutorial will show you the basic of Django when we will make a google search engine front end in the framework.

Extending the Django Admin Interface. This blog post is just a collection of notes I took along the way that might help you if you’ve had a play with the Django Admin and now are wondering how to get a little more out of it.
I have just spent a few weeks working on the first phase of an anlaytics dashboard application that is built using a mixture of Django, jQuery and Flash with the Isotoma crew. The project needed some way to set up the different sites and regions and rather than create these screens “by hand” we decided that the default Django Admin functionality would do this job well.
When I first saw the Django Admin screens I was shocked at how much you get “for free”. Having designed your database you can start editing it using screens that look better and work better than many CMSs. Despite Django Admin’s obvious abilities it is often thought of as being “only for the developer” and not something that you’d let a client loose on. My Approach I like things to be simple.

Convert Django Model Instances To Dictionaries. I just searched for a method to convert a model instance to a dictionary in Django and the top few results were a bunch of custom methods in Django Snippets and Stack Overflow.
I was about to use one of those when I clicked on one last link that showed me a better solution. There is a method already built into Django that does exactly what I want: django.forms.models.model_to_dict. As I pointed that out to a coworker, he showed me that that’s basically the same output as the .values() method in the queryset api. If you don’t specify a value to retrieve, it will retrieve the whole model instance as a dictionary. Here’s the output of these two pieces of code: Dynamic Models with Django. Asset Managers.

For example: Speciality: So if you want dynamic choices in the admin drop down you have to write a method that will return list with options and bind it to the form(as shown in Django forms ChoiceField with dynamic values…) which is used by admin.
This will work great but if you decided to add this column in admin`s list_filter you will see all element from the connected model in filter. How to limit them to the same list used for the form choices? Solution: The simplest solutions is to extend RelatedFilterSpec, overwrite its default choices and add a single row to the model: Python - Django view returning json without using template. Django tip: URL redirect shortcut. Bottom Line Up Front: Here’s a succinct, elegant way to do simple redirects in Django. Sometimes in a web app, you need to perform a simple redirect, pointing one URL to another. For example, in a current project, I need the / URL to redirect to /shop. I don’t need any complicated routing; I just need to rewrite one URL to another. (And, as happens sometimes, I don’t want to fiddle with the web server conf to do it.) The Django docs suggest creating a custom view function that takes care of the redirection. . # urls.py urlpatterns = patterns('', (r'^$', views.redirect_to_shop), ... ) # views.py from django.http import HttpResponseRedirect def redirect_to_shop(request): return HttpResponseRedirect("/shop/") ...
Writing a custom view seems like a bit of overkill here. Python - Using crontab with django. Python - For Django models, is there a shortcut for seeing if a record exists. Asset Managers.
