filterChanged() not working #872

Closed Josephine-Marie closed 2 years ago

Josephine-Marie commented 2 years ago

Hello, I am currently trying to implement the filter-functionality into my SHOP project, I have a product model that has a many2many relation to a catchphrase model. My filter looks like this: (same as docs)

class FilterForm(NgModelFormMixin, Bootstrap3Form):
    scope_prefix = 'filters'

class CatchphraseFilter(FilterSet):
    catchphrases = ModelMultipleChoiceFilter(
        queryset=Catchphrase.objects.all(),
        widget=SelectMultiple(attrs={'ng-change': 'filterChanged()'})
    )

    class Meta:
        model = Product
        form = FilterForm
        fields = ['catchphrases']

    @classmethod
    def get_render_context(cls, request, `queryset):`
        filter_set = cls(data=request.GET)

        filter_field = filter_set.filters['catchphrase'].field
        filter_field.queryset = filter_field.queryset.filter(
            id__in=queryset.values_list('catchphrases'))
        return dict(filter_set=filter_set)

the widget works fine, only the catchphrases that are currently used by products get displayed, but when I click on one of them the site reloads and nothing happens. (Also when I use "/?catchphrases", the shop page loads with all products). Also there is "[invalid name]" over the widget, I saw that I need a field name somewhere but where?

everything gets loaded correctly (angular modules etc.) but I cannot figure out why it is not filtering my products.

Thanks a lot for help in advance!
