Formset errors

[pinco]

Hi all,

I have a form and a formset that are passed to a template. I would
like to display any errors at the top of the template, using something
like this:

{% if form.errors or form.non_field_errors or formset.errors or
formset.non_form_errors %}
    <div class="error">
        <p>The operation could not be performed because one or more
error(s) occurred.<br />Please resubmit the form after making the
following changes:</p>

            {% if form.non_field_errors %}
                {{form.non_field_errors}}
            {% endif %}

            {% if form.errors %}
                <ul>
                {% for field in form %}
                    {% if field.errors %}
                        {% for error in field.errors %}
                            <li>{{field.label}}: {{error}}</li>
                        {% endfor %}
                    {% endif %}
                {% endfor %}
                </ul>
            {% endif %}

            {% if formset.non_form_errors %}
                {{form.non_form_errors}}
            {% endif %}

            {% if formset.errors %}
                {% for form in formset.forms %} {# formset.errors is a
list of dictionaries #}
                    {% if form.errors %}
                        <p>Choice #{{forloop.counter}}:</p>
                        <ul>
                        {% for field in form %}
                            {% if field.errors %}
                                {% for error in field.errors %}
                                    <li>{{field.label}}: {{error}}</
li>
                                {% endfor %}
                            {% endif %}
                        {% endfor %}
                        </ul>
                    {% endif %}g
                {% endfor %}
            {% endif %}

    </div>
{% endif %}


The problem is, apparently, that formset.errors is never empty, since
is a list of empty dictionaries (is this correct?).

The result is that I always get the:
<p>The operation could not be performed because one or more error(s)
occurred.<br />Please resubmit the form after making the following
changes:</p>
outputed, even if there are no errors in the form/formset (at least I
think this is the reason for that).

Any thoughts on how to avoid this behaviour? How can I check if a list
contains empty dictionaries within the template without iterating
through the list elements?


Thanks.

Paolo
