How to display multiple images in a django template img element - django

Question

I am having a challenge displaying multiple images users post to one img template element, for one reason if i try fetching images with the default related name it wouldn't show in the template and i wonder what i am doing wrong. Can anyone be of help!
Here is my model for post.
class Post(models.Model):
page = models.ForeignKey(Page, on_delete=models.CASCADE, related_name="page")
username = models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.CASCADE ,related_name="page_user")
description = models.TextField(max_length=500, blank=True)
video = models.FileField(upload_to="PageVideos", blank=True)
pic = models.ImageField(blank=True)
date_posted = models.DateTimeField(auto_now_add=True)
tags = models.CharField(max_length=100, blank=True)
class Mete:
ordering = ['-date_posted']
def __str__(self):
return self.description
class PostImage(models.Model):
#page = models.ForeignKey(Page, on_delete=models.CASCADE, related_name="pg")
post = models.ForeignKey(Post, default=None, on_delete=models.CASCADE)
images= models.ImageField(upload_to="postimages/")
Here is my Detail view
def page_detail(request,id):
post = get_object_or_404(Post, id=id)
photos = PostImage.objects.filter(post=post)
context = {
'post':post,
'photos':photos
}
return render(request, 'page/detail.html',context)
These my Template to display users images
<div class="p-3 border-b dark:border-gray-700">
{{ post.description }}
</div>
<div uk-lightbox>
<div class="grid grid-cols-2 gap-2 p-2">
{% for p in photos.images_set.all %}
<a id="images" href="{{ p.images.url }}" class="col-span-2" >
<img src="{{ p.images.url }}" alt="" class="rounded-md w-full lg:h-76 object-cover">
</a>
<a href="">
<img src="" alt="" class="rounded-md w-full h-full">
</a>
<a href="" class="relative">
<img src="" alt="" class="rounded-md w-full h-full">
<div class="absolute bg-gray-900 bg-opacity-30 flex justify-center items-center text-white rounded-md inset-0 text-2xl"> + see more </div>
</a>
{% endfor %}
</div>
</div>

Answer 1

your photos is a list you dont need reverse m2m (the "images_set") simply change this in html
....
<div class="grid grid-cols-2 gap-2 p-2">
{% for p in photos %}
....
for optimize you can do this
from django.http import Http404
...
def page_detail(request,id):
try:
# with prefetch you do only one sql request
post = Post.objects.select_related('images_set').get(id=id)
expect Post.DoesNotExist as err:
raise Http404(err)
context = {
'post': post,
'photos': post.images_set.all()
}
return render(request, 'page/detail.html',context)
