Question: I realize this is probably a beginner level error, but I'm out of ideas. I need to add pagination to Inline model for admin page. I'm using Django 1.8.4 ( yup, I know it's really old ) and python 3.6.15. Inside admin.py: class ArticleInline(GrappelliSortableHiddenMixin, admin.TabularInline): model = ArticleSection.articles.through raw_id_fields = ("article",) related_lookup_fields = { 'fk':['article'], } extra = 1 class ArticleSectionsAdmin(reversion.VersionAdmin): list_display = ('name','slug','template_file_name') inlines = [ArticleInline] admin.site.register(ArticleSection,ArticleSectionsAdmin)  Inside models.py: class ArticleSection(Section): articles = models.ManyToManyField(Article, verbose_name=_("article"), through="M2MSectionArticle", related_name="sections") limit = models.PositiveSmallIntegerField(default=10) class Meta: db_table = 'sections_article_section' verbose_name = _("article section") verbose_name_plural = _("articles sections") def content(self, request): query = Q(m2msectionarticle__visible_to__isnull=True) & Q(m2msectionarticle__visible_from__isnull=True) query.add(Q(m2msectionarticle__visible_to__gte=timezone.now(), m2msectionarticle__visible_from__lte=timezone.now()), Q.OR) limit = self.limit_override if hasattr(self, 'limit_override') and self.limit_override is not None else self.limit return self.articles.filter(query).published().prefetch_related('images').order_by('m2msectionarticle__position')[:limit] class M2MSectionArticle(models.Model): section = models.ForeignKey(ArticleSection, related_name='section_articles') article = models.ForeignKey(Article, verbose_name=_('article')) position = models.PositiveSmallIntegerField(_("position"), default=0) visible_from = models.DateTimeField("Widoczne od", null=True, blank=True) visible_to = models.DateTimeField("Widoczne do", null=True, blank=True) class Meta: db_table = 'sections_section_articles' ordering = ["position"]  I found django-admin-inline-paginator and it seems to work for everyone else, but I get "Function has keyword-only parameters or annotations, use getfullargspec() API which can support them" when I use TabularInlinePaginated instead of admin.TabularInline. from django_admin_inline_paginator.admin import TabularInlinePaginated class ArticleInline(GrappelliSortableHiddenMixin, TabularInlinePaginated): model = ArticleSection.articles.through raw_id_fields = ("article",) related_lookup_fields = { 'fk':['article'], } extra = 1 per_page = 10  print(inspect.getfullargspec(TabularInlinePaginated)) returns : FullArgSpec(args=['self', 'parent_model', 'admin_site'], varargs=None, varkw=None, defaults=None, kwonlyargs=[], kwonlydefaults=None, annotations={})  but I still dont know what to do.

Answer: This is due to compatibility issues between older versions of Python and Django when handling function signatures.. for example, related_lookup_fields is Deprecated in Django Admin such that the part related_lookup_fields = { 'fk': ['article'], }  should be replaced by autocomplete_fields = ["article"]  or just remove it entirely. So in a nutshell this will fix only THAT part and you'd have to go over each section of the code i.e. just move over to newer version
