Django Restframework “Got AttributeError when attempting to get a value for field `section_type` on serializer `QuestionSerializer`

This is my model.

class QuestionSection(models.Model):
 section = models.CharField(max_length = 100, null = True, blank = True)
 max_marks = models.IntegerField()

 def __str__(self):
 return self.section

class Question(models.Model):
 question_section = models.ForeignKey(QuestionSection, on_delete = models.CASCADE, related_name = 'questions')
 section_type = models.CharField(max_length = 10,)
 questions = models.CharField(max_length = 350, null = True, blank = True)
 image = models.CharField(max_length = 10, null = True, blank = True)
 no_of_images = models.IntegerField(null = True, blank = True)
 marks = models.IntegerField()
 shop_view = models.CharField(max_length = 30, null = True, blank = True, choices=(('critical', 'critical'), ('major', 'major')))
 what_to_look_for = models.CharField(max_length = 350, null = True, blank = True)

 def __str__(self):
 return "-".format(self.section_type, self.marks)

This is my serializer

class QuestionSerializer(serializers.ModelSerializer): 
 class Meta:
 model = Question
 fields = '__all__'

class QuestionSectionSerializer(serializers.ModelSerializer):
 questions = QuestionSerializer(read_only = True)
 class Meta:
 model = QuestionSection
 fields = '__all__'

I am not able to figuring out how to do it. The API will be like QuestionSection fields and inside that Question fields will be there.

  Likely bot your error but you probably mean to put a "many=true" in your QuestionSeftuonSerializer.questions field. As to your error: have you made migrations and migrated your models?
