django-filtered-form Description

django-filtered-form is a form that can have per-field queryset filters declaratively defined.InstallationIn your virtualenv, use pip install django-filteredform.You don't need to install it into your settings.INSTALLED_APPS, as it does not provide any models or templates, only forms.UsageDeclarative way to define filters on fields on a django model form:from django import formsfrom people.models import Personfrom filtered_form.forms import FilteringFormclass PersonAdminForm(FilteringForm): class Meta: model = Person instance_filters = { 'units': 'company.units' } filters = { 'units': models.Q(is_active=True), 'colours__in': }instance_filtersinstance_filters are things that allow for relational filters to be applied.For instance, if you have a triple of models, Person, Unit and Company, and every person and unit have a foreign key to a company, you can use an instance filter to easily select only the associated company's units for a queryset when viewing a person.Alternatively, you can supply a queryset method (that does not require arguments), for more filtering:instance_filters = { 'units': 'company.units.active'}plain filtersA more conventional filter structure, that allows you to supply a Q object, or a dict of key-value pairs, which will be passed to .filter() on the queryset.You can quite easily shoot yourself in the foot if your filter keys are not valid arguments for a filter function on that queryset.FormSetsYou can either create a form using this method, and then pass that to your formset class or factory. Or, you can have a formset class based on filtered_form.forms.FilteredFormSet, which will also set up the queryset values on the empty form correctly, which is very useful if you are using dynamic forms.Product's homepage
