In django.contrib.auth.forms.AuthenticationForm there is no separate check for empty form input

[lgp171188@…]

In django.contrib.auth.forms.AuthenticationForm there is no check check for empty form input data and treat it as a separate validation error. Instead it returns the generic Your username and password didn't match. Please try again. which is more appropriate for invalid credentials.

I'm going to close this ticket as "worksforme", as with the information you provided, i couldn't reproduce the bug.

Please, if you believe this is indeed a bug, feel free to reopen this ticket, and provide extensive details on how to reproduce it, thanks !

FYI, here's the code I used to try to reproduce the bug:

# views.py
class MyFormView(FormView):
    template_name = 'testapp/form.html'
    form_class = AuthenticationForm
    success_url = "/"
form_view = MyFormView.as_view()


# urls.py
from testapp.views import form_view

urlpatterns = patterns('',
    url(r'^form/$', form_view, name='form'),
)


# templates/testapp/form.html
<form method="post" action="">{% csrf_token %}
    {% include "form_include.html" %}
    <input type="submit" value="submit" />
</form>


# form_include.html
{% if form.errors %}
<p class="error">Please correct the following errors:</p>
{% endif %}

{% for field in form %}
    <div class="form-row{% if field.field.required %} required{% endif %}{% if field.errors %} error{% endif %}">
        {{ field.errors }}
        {{ field.label_tag }} {{ field }}
        {% if field.help_text %}<p class="help">{{ field.help_text }}</p>{% endif %}
    </div>
{% endfor %}

When i go to /form/, i do indeed see a username and a password input fields, and if i submit straight away, without submitting any data, there's an error for each field stating "This field is required."
