python - How to show dynamic custom actions by selected custom filter in Django -

class evidencefilter(simplelistfilter):     title = _('evidence')     parameter_name = 'evidence'      def lookups(self, request, model_admin):                     return evidence_status_choices      def queryset(self, request, queryset):         if self.value():             if self.value() == 'pending':                                     return queryset.filter(q(profile__identity_verified='pending') & (q(person_id_status='pending') | q(person_selfie_status='pending') | q(org_certificate_status='pending') | q(org_taxid_status='pending')))             elif self.value() == 'accepted':                 return queryset.filter(q(profile__identity_verified='pending') & ((q(person_id_status='accepted') & q(person_selfie_status='accepted')) | (q(org_certificate_status='accepted') & q(org_taxid_status='accepted'))))             elif self.value() == 'rejected':                 return queryset.filter(q(profile__identity_verified='pending') & ((q(person_id_status='rejected') | q(person_selfie_status='rejected')) | (q(org_certificate_status='rejected') | q(org_taxid_status='rejected'))))         else:             return queryset  class evidenceadmin(admin.modeladmin):     list_display = ('id', 'profile', 'person_id_status', 'person_selfie_status', 'org_certificate_status', 'org_taxid_status')     list_filter = (evidencefilter,)     actions = ['make_approved', 'make_denied']      class meta:         exclude = []      def get_actions(self, request):         actions = super(evidenceadmin, self).get_actions(request)         if self.list_filter[0].value()=='pending':             if 'make_approved' in actions:                 del actions['make_approved']             if 'make_denied' in actions:                 del actions['make_denied']         return actions      def make_approved(modeladmin, request, queryset):         evidence in queryset:             evidence.profile.identity_verified = "approved"             evidence.profile.save()     make_approved.short_description = "approve selected evidences"      def make_denied(modeladmin, request, queryset):         evidence in queryset:             evidence.profile.identity_verified = "denied"             evidence.profile.save()     make_denied.short_description = "deny selected evidences" 

in get_actions function of evidenceadmin modeladmin class going give special condition evidencefilter's selected value equal *pending*.

if self.list_filter[0].value()=='pending': 

but can't use self.list_filter[0].value() selected value of evidencefilter. following error because of it.

typeerror @ /admin/securities/evidence/ value() missing 1 required positional argument: 'self' 

any suggestions or improvements welcome. need guidance on this... thanks...
