I want to filter the parent value from the child model with Django reverse reference and extract the data.

import datetime
from django.db import models
from django.utils import timezone

# Create your models here.
# Each model inherits models.Model.
# Become a subclass of models.model.
class Question (models.Model):
  # Define class variables.Represents a database field.
  # Char field is a character field
  question_text=models.CharField(max_length=200)

  # Date and Time Fields
  pub_date=models.DateTimeField('date published')

  def__str__(self):
    # When an instance is generated and printed, it is executed.
    # In addition to using question names for objects that appear in the shell,
    # It is also used to represent objects in admin, so it needs to be added.
    return self.question_text
  
  def was_published_recently(self):
    now=timezone.now()
    # Now-datetime.timedelta(days=1) gives the date minus one day from this time.
    # 2021-05-19 23:29:56.216634 The value will look like this.
    # A method that returns True if pub_date is older than the current time and less than one day from the current time.
    return now-datetime.timedelta(days=1)<=self.pub_date<=now

Class Choice (models.Model):

  # This tells you that Choice is associated with Question.
  # Corresponds to database relationships such as many-to-one, many-to-many, and one-to-one.
  # Interactive interaction with Question←→ Choice is now possible.
  question=models.ForeignKey (Question, on_delete=models.CASCADE)
  choice_text=models.CharField(max_length=200)
  votes=models.IntegerField(default=0)

  def__str__(self):
    return self.choice_text
