Django 1.1 Testing and Debugging

Overview of this book

Bugs are a time consuming burden during software development. Django's built-in test framework and debugging support help lessen this burden. This book will teach you quick and efficient techniques for using Django and Python tools to eradicate bugs and ensure your Django application works correctly. This book will walk you step by step through development of a complete sample Django application. You will learn how best to test and debug models, views, URL configuration, templates, and template tags. This book will help you integrate with and make use of the rich external environment of test and debugging tools for Python and Django applications. The book starts with a basic overview of testing. It will highlight areas to look out for while testing. You will learn about different kinds of tests available, and the pros and cons of each, and also details of test extensions provided by Django that simplify the task of testing Django applications. You will see an illustration of how external tools that provide even more sophisticated testing features can be integrated into Django's framework. On the debugging front, the book illustrates how to interpret the extensive debugging information provided by Django's debug error pages, and how to utilize logging and other external tools to learn what code is doing.

We have the display of a single question form working, what's left to do? First, we need to handle the display of however many questions that are associated with a survey, instead of just a single question. Second, we need to handle receiving, validating, and processing the results. We'll focus on the first task in this section.

Creating the data for multiple questions

Before writing the code to handle multiple questions, let's add another question to our test survey so that we'll be able to see the new code work. The upcoming examples will display this additional question:

Coding support for multiple questions

Next, change the view to create a list of QuestionVoteForms and pass this list in the template context:

def display_active_survey(request, survey): 
    qforms = [] 
    for i, q in enumerate(survey.question_set.all()): 
        if q.answer_set.count() > 1: 
            qforms.append(QuestionVoteForm(q, prefix=i)) 
    return render_to_response('survey...
