Getting Started with Django Logging in 5 Minutes posted by Ian on April 16, 2013 Setting up Django logging can sometimes be a little complex, so here are the no-nonsense steps required to make a new Django 1.5 instance log to a file without hassles. We’re going to look at each of the 4 components of Django logging: Loggers: a logger is the object that we will use to pass messages to the logging systemHandlers: the handler is an engine that determines what to do with a message when it is recieved from the loggerFilters: allow you to restrict the type of messages that are sent from the logger to the handlerFormatters: describe the text representation of the log message Simple, right? For more information, check out the Django documentation on logging. Setting up your Project for Logging Logging configuration is specified in your project’s settings.py file.
Formatters First let’s declare the format that we can log entries in. Filters In my example, I don’t want to filter anything. Handlers Loggers. Quick start guide — django-registration 1.0 documentation. Once installed, you can add django-registration to any Django-based project you’re developing. The default setup will enable user registration with the following workflow: Note that the default workflow requires django.contrib.auth to be installed, and it is recommended that django.contrib.sites be installed as well. You will also need to have a working mail server (for sending activation emails), and provide Django with the necessary settings to make use of this mail server (consult Django’s email-sending documentation for details). Required settings¶ Begin by adding registration to the INSTALLED_APPS setting of your project, and specifying one additional setting: This is the number of days users will have to activate their accounts after registering.
For example, you might have something like the following in your Django settings file: INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.sites', 'registration', # ...other installed applications...) Setting up URLs¶ Required templates¶ Learn Python. Obey the Testing Goat! Someone recently wrote to me asking about decorators, and saying they found them a bit confusing. Here's a post based on the email I replied to them with. The best way to understand decorators is to build a couple of them, so here are two examples for you to try out. The first is in the Django world, the second is actually a simpler, pure-python one. Challenge: build a decorator in a simple Django app We've built a very basic todo lists app using Django.
(Full code here) This is a good use case for a decorator. A decorator can be used to extract duplicated work, and also to change the arguments to a function. So how do we build a decorator that does that? (you end up saying "function" a lot in any explanation of decorators...) Here's a template: def get_list(view_fn): def decorated_view(...?) Can you get it working? Git clone -b chapter_06 manage.py test lists # dependencies: django 1.7 Some rules of thumb for decorators: A simpler decorator challenge: Python Tutorials. Python.

Django. Python. DjangoCheatSheet. The django tutorials are quite good. The goal of this cheat sheet is to create a quick start guide so that after reading the tuts over once or twice you have a more handy reference. Things in this guide are done the 'right' way with generic views and templates right off the bat. Please please add to this page.

How to Think Like a Computer Scientist. Python Programming - Wikibooks, open books for an open world. Python Programming From Wikibooks, open books for an open world Jump to: navigation, search This book describes Python, an open-source general-purpose interpreted programming language available for a broad range of operating systems. There are currently three major implementations: the standard implementation written in C, Jython written in Java, and IronPython written in C# for the .NET environment. There are two common versions currently in use: 2.x and 3.x.
This book describes primarily version 2, but does at times reference changes in version 3.

Python Examples. On these pages, I have collected a bit of information about the Python programming language, along with a bunch of examples. These might be useful if you want to see some of the features without actually learning the language itself.
You don't have to read through all of this in order. Just pick the pages which look most interesting to you. The topics are fairly independent from each other and don't require any existing knowledge about Python. Note: Some of the examples might require at least Python 2.3. Small code examples This page contains a few small code snippets, to give you an impression how the programming language looks like.
Lambda functions Several useful concepts of Python have been borrowed from functional languages. Dynamic typing In Python, everything has a well-defined type, and these types can be handled completely at runtime in a dynamic and self-inspective fashion. Structured types List comprehensions Block indentation Python Tutorial - Read this one first!!! Google's Python Class - Google's Python Class - Google Code. Welcome to Google's Python Class -- this is a free class for people with a little bit of programming experience who want to learn Python.
The class includes written materials, lecture videos, and lots of code exercises to practice Python coding. These materials are used within Google to introduce Python to people who have just a little programming experience. The first exercises work on basic Python concepts like strings and lists, building up to the later exercises which are full programs dealing with text files, processes, and http connections. The class is geared for people who have a little bit of programming experience in some language, enough to know what a "variable" or "if statement" is. Beyond that, you do not need to be an expert programmer to use this material. This material was created by Nick Parlante working in the engEDU group at Google. Special thanks for the help from my Google colleagues John Cox, Steve Glassman, Piotr Kaminski, and Antoine Picard.
Python - Functions. A function is a block of organized, reusable code that is used to perform a single, related action. Functions provide better modularity for your application and a high degree of code reusing. As you already know, Python gives you many built-in functions like print(), etc. but you can also create your own functions. These functions are called user-defined functions. Defining a Function You can define functions to provide the required functionality. Function blocks begin with the keyword def followed by the function name and parentheses ( ( ) ).Any input parameters or arguments should be placed within these parentheses.
Syntax def functionname( parameters ): "function_docstring" function_suite return [expression] By default, parameters have a positional behavior and you need to inform them in the same order that they were defined. Example The following function takes a string as input parameter and prints it on standard screen. Calling a Function #! I'm first call to user defined function! #! #! #!
