Django的Charfields神奇地充满了一些价值观

Question

views.py：

def index(request):
    articles = Main.objects.all()
    login_form2 = LoginForm2()
    ResponseDict = {"active_page_id": "index", "articles": articles, "login_form2": login_form2}
    return render_to_response("index.html", ResponseDict, 
        context_instance = RequestContext(request))

forms.py：

class LoginForm2(forms.Form):
    login2 = forms.CharField(max_length=100)
    pwd2 = forms.CharField(max_length=100, widget=forms.PasswordInput)

模板：

<div id="col-in">
    <h3><span>Authorization</span></h3>
        <form action="" method="POST">
            {% csrf_token %}
                <div class="error" id="error">{{ auth_error }}</div><br />
                {{ login_form2.login2 }}
                {{ login_form2.pwd2 }}
                <input type="submit" name="auth_submit" value="Submit">
        </form>
</div>

当我使用此模板进入页面时，“login2”和“pwd2”字段已经填满（可能是Django admin的auth数据）。至于我，这里发生了一些黑魔法。如何在页面上显示这些值以及如何正确显示身份验证表单？
