How to render the values in a parent child relationship in Django – Telegram API

I am creating a django app where the admin can add travel packages. To add the explicit details of the package I created a child that will handle those values. Here is how the code looks like.

class Category(models.Model):
    title = models.CharField(max_length=30)
    slug = models.SlugField(unique=True)

class Meta:
    ordering = ['title']

def __str__(self):
    return self.title


class SafariPackages(models.Model):
    image = models.ImageField(upload_to='SafariPackages/%Y/%m/%d', null=False)
    title = models.CharField(max_length=200)
    cost = models.FloatField(null=False)
    days = models.FloatField(blank=False, null=False)
    nights = models.FloatField(blank=False, null=False)
    category = models.ManyToManyField(Category)
    exodus = models.CharField(max_length=200)
    destination = models.CharField(max_length=200)
    telegram = models.TextField(max_length=140, null=False)
    description = models.TextField(null=False)
    slug = models.SlugField(max_length=200, unique=True)

objects = EntryQuerySet.as_manager()

def __str__(self):
    return self.title

class Meta:
    verbose_name = 'Safari Package Entry'
    verbose_name_plural = 'Safari Package Entries'

class DayNumber(models.Model):
    daydetails = models.ForeignKey(SafariPackages, related_name='daydetails', default=1, on_delete=models.CASCADE)
    day_number = models.CharField( max_length=10, null=True, blank=True)
    image = models.ImageField (upload_to='SafariPackagesDetails/%Y/%m/%d', null=False, default=1)
    day_description = models.TextField()

The views that I have so far look like this

def safaripackages_view(request, *args,**kwargs):
    print (args, kwargs)
    print (request.user)

    all_safaripackages = SafariPackages.objects.all()

#Paginator
paginator = Paginator(all_safaripackages, 8)    
page = request.GET.get('page')      
try:
    all_safaripackages = paginator.page(page)
except PageNotAnInteger:
    all_safaripackages = paginator.page(1)
except EmptyPage:
    all_safaripackages = paginator.page(paginator.num_pages)


context = {
'all_safaripackages': all_safaripackages,
}


return render (request, "safaripackages.html", context)

def single_safaripackage(request, post_id):
    safaripackage = SafariPackages.objects.get(pk=post_id)
    return render (request, 'single_safaripackage.html', {'safaripackage':safaripackage,})

How do I include the values of the DayNumber model in the single_safaripackage view?
