I got a problem with pagination after using django_filter in my TemplateView. Before use django_filter, my pagination was working normally but now it show all the items in every page, I've been looking on the internet but I didn't find a good solution for this. how can I fix it? thanks

my filter.py

class SnippetFilter(django_filters.FilterSet):
    area = []
    tecnology = Technology.objects.values('parent_area').distinct().order_by('parent_area_id')
    for a in tecnology:                                                                         
        area.append(a['parent_area']) 

    parent_area = django_filters.ModelMultipleChoiceFilter(queryset=ApplicationArea.objects.filter(id__in=area), widget=forms.CheckboxSelectMultiple)

    class Meta:
        model = Technology
        fields = ['title', 'category', 'kind', …

我在使用 ModelForm 添加 ManyToMany 字段时遇到问题，问题是我不知道如何创建子表单以将此数据添加到我的主表单。我想创建一个在单击按钮时保存的子表单，并且我希望选择保存的数据在主表单中使用。
