And i want to post them in one page i need to take price rows exactly declared for this medical service I cant get the idia how to get it done through admin panel (i dont know how to insert quantity value quantity into it) I created an intermidiate model (services_count) but i think its not best idea :0

from django.db import models
from tinymce import models as tiny_models
from django.urls import reverse

class Medservices(models.Model):
    public = 'pub'
    private = 'priv'
    status_post = [(public,'public'),(private,'private')]
    position = models.IntegerField(default=1, verbose_name="Позиція")
    status = models.CharField(max_length=10,default=public,choices=status_post, verbose_name="Статус показу")
    photo = models.ImageField(verbose_name='Фото послуги або акції', upload_to='services_images', max_length=None)
    date_start = models.DateField(verbose_name='Дата початку', auto_now=False, auto_now_add=False)
    date_expire = models.DateField(verbose_name='Дата початку', auto_now=False, auto_now_add=False)
    title = models.CharField(verbose_name='Назва послуги або акції', max_length=300)
    text = text = tiny_models.HTMLField()
    slug = models.SlugField(max_length=255,unique=True,verbose_name="URL",db_index=True)

def __str__(self):
    return f"{self.price.all} - to {self.status}"

def get_absolute_url(self):
    return reverse('service_page', kwargs={'post_slug': self.slug})

class services_count(models.Model):
    quantity = models.IntegerField(verbose_name='Кількість цієї послуги у сервісі')
    service = models.ForeignKey("medservices.Medservices", verbose_name='Послуга або акція', on_delete=models.CASCADE)
    prices = models.ManyToManyField("price.Price", verbose_name='Ціни')
