login auth issue - beginner

[Phil]

Hi, 

I am new to Django and am trying to use the built in auth features for the first time. I have been following the steps on the djangobook website here... 

http://www.djangobook.com/en/1.0/chapter12/ 

However I am getting the following error on my login page. Anyone know where I am going wrong?...

hi.. your request is  GET, and you try get the query data with POST .

this the errror cause 

16. username = request.POST['username']    

Exception Value: "Key 'username' not found in <QueryDict: {}>" 

check your login form to use POST..

HTH,

Thanks for reply. 

Yes my form is using POST. Here is my template file...

{% block content %}

  {% if form.errors %}

    <p class="error">Sorry, that's not a valid username or password</p>

  {% endif %}

  <form action='/' method='POST'>

    <label for="username">User name:</label>

    <input type="text" name="username" value="" id="username">

    <label for="password">Password:</label>

    <input type="password" name="password" value="" id="password">

    <input type="submit" value="login" />

    <input type="hidden" name="next" value="{{ next|escape }}" />

  </form>

{% endblock %}

Hi, Your traceback is from a 'login' function buy you're posting to
base '/'
Could that be an issue??
The traceback clearly explains what the problem is, no data is
arriving at your login function
