Django _set.all in template with one to many relationship - django

Question

I am trying to output a web page with many blog posts, each of them potentially containing many images.
Models.py:
class FreeImage(models.Model):
f_img = models.ImageField(null=True, blank=True, upload_to="img/f")
f_img_alt = models.CharField(max_length=100, blank=True, null=True)
post = models.ForeignKey('Post', on_delete=models.SET_NULL, null=True)
class Post(models.Model):
title = models.CharField(max_length=100, unique=True)
Views.py:
def home_view(request):
posts = Post.objects.order_by('-id')
freeimgs = FreeImage.objects.filter(post__in=posts)
context = {
'posts':posts,
'freeimgs' :freeimgs,}
return render(request, 'home.html', context)
Template:
{% extends 'base.html' %}
{% block main %}
{% for post in posts%}
<h3>{{post.title}}</h3>
{% for i in freeimgs.post_set.all %}
<h5>Test</h5>
<img src="{{ freeimage.f_img.url }}" alt="{{freeimage.f_img_alt}}">
{% endfor %}
{% endfor %}
{% endblock %}
freeimgs.post_set.all does not return anything here. I have no idea how else I could show the images corresponding to the right post inside template.

Answer 1

You have reverse accessor from Post to FreeImage and not other way around
{% for free_image in post.freeimage_set.all %}
<h5>Test</h5>
<img src="{{ free_image.f_img.url }}" alt="{{ free_image.f_img_alt}}">
{% endfor %}
