How can I solve the Not found problem when getting from pytest-django through pk?

Question

I have a problem with django-pytest
I'm using, djnago-rest-framework
There is a problem testing the details. As shown in the code below, I entered the same details, detail1, detail2, and detail3 codes. However, only detail1 succeeds and detail2, detail3 indicates that '/api/v1/stats/1/' could not be found. It also occurs when implementing delete. I am curious about the cause and solution of this error.

// tests/test_apis.py
import json
from django.urls import reverse
from rest_framework import status
from rest_framework.test import APITestCase
from stats.models import Stats


class StatsApiTests(APITestCase):
    def setUp(self):
        Stats.objects.get_or_create(blockshots=1, memo='test1')
        Stats.objects.get_or_create(blockshots=2, memo='test2')
        self.create_read_url = reverse('api:stats:stats-list')
        self.read_update_delete_url = reverse('api:stats:stats-detail', kwargs={'pk': '1'})

    def test_detail1(self):
        response = self.client.get(self.read_update_delete_url)
        data = json.loads(response.content)
        content = {
            'blockshots': 1,
            'memo': 'test1',
        }
        self.assertEqual(data, content)

    def test_detail2(self):
        response = self.client.get(self.read_update_delete_url)
        data = json.loads(response.content)
        content = {
            'blockshots': 1,
            'memo': 'test1',
        }
        self.assertEqual(data, content)

    def test_detail3(self):
        response = self.client.get(self.read_update_delete_url)
        data = json.loads(response.content)
        content = {
            'blockshots': 1,
            'memo': 'test1',
        }
        self.assertEqual(data, content)

    def test_list(self):
        response = self.client.get(self.create_read_url)
        self.assertContains(response, 'test1')
        self.assertContains(response, 'test2')

Its hard to know what your actual implementation for read_update_delete_url, hence I assume it is looking up the resource by primary key. In that case, you can simply add the primary key in the url like this:

stat_one, _ = Stats.objects.get_or_create(blockshots=1, memo='test1')
stat_two, _ = Stats.objects.get_or_create(blockshots=2, memo='test2')

self.read_update_delete_url = reverse('api:stats:stats-detail', kwargs={'pk': stat_one.pk})

Basically, get_or_create returns the object and the state of the object (created or not). You can use the object's id as the parameter of reverse function.
