django-form-utils is a Django application that provides BetterForm and BetterModelForm classes which are subclasses of django.

django-form-utils is a Django application that provides BetterForm and BetterModelForm classes which are subclasses of django.forms.Form and django.forms.ModelForm, respectively. BetterForm and BetterModelForm allow subdivision of forms into fieldsets which are iterable from a template, and also allow definition of row_attrs which can be accessed from the template to apply attributes to the surrounding container (< li >, < tr >, or whatever) of a specific form field.Installation:Once installed on your Python path (see INSTALL.txt), just include form_utils in your INSTALLED_APPS setting. django-form-utils does not provide any models, but including it in INSTALLED_APPS makes the form_utils template tag library available.You may also want to override the default form rendering templates by providing alternate templates at templates/form_utils/better_form.html and templates/form_utils/form.html.Usage:Simply inherit your form class from form_utils.forms.BetterForm (rather than django.forms.Form), or your modelform class from form_utils.forms.BetterModelForm, and define the fieldsets and/or row_attrs attributes of the inner Meta class:class MyForm(BetterForm): one = forms.CharField() two = forms.CharField() three = forms.CharField() class Meta: fieldsets = (('main', {'fields': ('two',), 'legend': ''}), ('Advanced', {'fields': ('three', 'one'), 'description': 'advanced stuff'})) row_attrs = {'one': {'style': 'display: none'}}Fieldset definitions are similar to ModelAdmin fieldset definitions: each fieldset is a two-tuple with a name and an options dictionary. Valid fieldset options in the dictionary include:fields (required) A tuple of field names to display in this fieldset.classes A list of extra CSS classes to apply to the fieldset.legend This value, if present, will be the contents of a legend tag to open the fieldset. If not present the name of the fieldset will be used (so a value of '' for legend must be used if no legend is desired.)description A string of optional extra text to be displayed under the legend of the fieldset.When iterated over, the fieldsets attribute of a BetterForm (or BetterModelForm) yields Fieldset s. Each Fieldset has a name attribute, a legend attribute, and a description attribute, and when iterated over yields its BoundField s.For backwards compatibility, a BetterForm or BetterModelForm can still be iterated over directly to yield all of its BoundField s, regardless of fieldsets.For more detailed examples, see the doctests in tests/__init__.py.Rendering:A possible template for rendering a BetterForm:{% if form.non_field_errors %}{{ form.non_field_errors }}{% endif %}{% for fieldset in form.fieldsets %} < fieldset class="fieldset_{{ fieldset.name }}" > {% if fieldset.legend %} < legend >{{ fieldset.legend }}< /legend > {% endif %} {% if fieldset.description %} < p class="description" >{{ fieldset.description }}< /p > {% endif %} < ul > {% for field in fieldset %} {% if field.is_hidden %} {{ field }} {% else %} < li{{ field.row_attrs }} > {{ field.errors }} {{ field.label_tag }} {{ field }} < /li > {% endif %} {% endfor %} < /ul > < /fieldset >{% endfor %}django-form-utils also provides a convenience template filter, render. It is used like this:{{ form|render }}By default, it will check whether the form is a BetterForm, and if so render it using the template form_utils/better_form.html. If not, it will render it using the template form_utils/form.html. (In either case, the form object will be passed to the render template's context as form).The render filter also accepts an optional argument, which is a template name or comma-separated list of template names to use for rendering the form:{{ form|render:"my_form_stuff/custom_form_template.html" }}Please report bugs to the official home page: http://launchpad.net/django-form-utils
