add a fieldset.errors dictionary to use in templates

[Felipe 'chronos' Prenholato]

I propose with one patch a change that allow to have a fieldset.errors, that is a dict grouping all errors of fieldset fields.
Example:

form = EnhancedForm({})
for fs in form:
print fs.errors

Example output:
{'category': {'errorlist': [u'This field is required.'], 'label': u'Category'},
 'manufacturer': {'errorlist': [u'This field is required.'], 'label': u'Manufacturer'}}

The great use is in templates:

{% for errors in fieldset.errors.itervalues %}
    {% if forloop.first %}
        <ul class="errors">
    {% endif %}
    <li>{{ errors.label }}: {% for e in errors.errorlist %}{{ e }}{% if not forloop.last %}, {% endif %}{% endfor %}</li>
    {% if forloop.last %}
        </ul>
    {% endif %}
{% endfor %}

I attach the patch and generic template that I using this change.

Good idea. I would prefer to see the fieldset errors be a property calculated on demand rather than assigned at FieldSet creation, but I can easily make that change. Thanks!

Fixed in trunk r15.
