class quiz(models.model):     quiz_title = models.charfield(max_length=200)     created_date = models.datetimefield('date created')     expired_date =  models.datetimefield(         null=true, blank=true)      def __str__(self):         return self.quiz_title  class question(models.model):     quiz = models.foreignkey(quiz, on_delete=models.cascade)     question_text = models.charfield(max_length=200)     answer = models.charfield(max_length=200,blank=true)       def __str__(self):         return self.question_text  class choice(models.model):     question = models.foreignkey(question, on_delete=models.cascade)     choice_text = models.charfield(max_length=200)       def __str__(self):         return self.choice_text  class usersession(models.model): #for future use.      user = models.foreignkey(user)     quiz = models.foreignkey(quiz, on_delete=models.cascade)     question = models.foreignkey(question, on_delete=models.cascade)     user_answer = models.charfield(max_length=200) 

and here admin django.contrib import admin

# register models here. .models import choice, question, quiz  class choiceinline(admin.tabularinline):     model = choice     = 3 class questioninline(admin.tabularinline):     model = question     = 3 class questionadmin(admin.modeladmin):     fieldsets = [         (none,  {'fields': ['question_text']}),         ('date information', {'fields': ['question_text'], 'classes':    ['collapse']}),     ]     inlines = [choiceinline]     list_filter = ['question_text']     search_fields = ['question_text']     list_display = ('question_text',) class quizadmin(admin.modeladmin):     fieldsets = [         (none,  {'fields': ['quiz_title']}),         ('date information', {'fields': ['created_date'], 'classes':    ['collapse']}),     ]     inlines = [questioninline]     list_filter = ['created_date']     search_fields = ['quiz_title']     list_display = ('quiz_title', 'created_date')  admin.site.register(quiz, quizadmin) #~ admin.site.register(question, questionadmin) 

django doesn't support nested inlines without building functionality or using admin nested inline app not date.

a common pattern link directly child object new modeladmin view.

create readonly field renders link.

class questioninline(admin.tabularinline):     model = question     = 3     readonly_fields = ('link', )     def link(self, obj):         return '<a href="%s" target="_blank">edit</a>' % reverse('admin:appname_modelname_change', args=[obj.id])      link.allow_tags = true
