The problem is that I get an error when I try to display a block on a page, I don't really know what to do, since I'm working with a template engine for the first time. this is code of views.py

class IndexView(generic.ListView):
template_name = 'Homepage/index.html'
model = Goods
context_object_name = 'goods'

def sale(request):
    return render(request, 'articles/sale.html')

this is code of index.html

{% include "article/sale.html" %}
{% block sale %}

{% endblock %}

<iframe name="sif1" sandbox="allow-forms allow-modals allow-scripts" frameborder="0"></iframe>

this is code of sale.html

{% extends "Homepage/index.html" %}

{% block sale %}

<td class ="sale">
      <img src="https://upload.wikimedia.org/wikipedia/commons/thumb/b/b6/Image_created_with_a_mobile_phone.png/1280px-Image_created_with_a_mobile_phone.png">

        <h1 class="description">ОписаниеОписаниеОписаниеОписание</h1>

  <a class="buy" href="#openModal" >
    <span >Купить</span></a>
  <h1 class="price">цена</h1>
  </td>


{% endblock %}

<iframe name="sif2" sandbox="allow-forms allow-modals allow-scripts" frameborder="0"></iframe>

This is building a template

in the end it gives an error maximum recursion depth exceeded while calling a Python object вот TraceBack

CodePudding user response：

Your index.html template includes the sales.html template, and the sales.html template extends the index.html template. As a result if you render index.html or sale.html, it will get stuck in an infinite loop.

You can remove the {% include 'article/sales.html' %} part of the index.html page. The fact that you defined a block that can be filled in by the sales.html template is sufficient.
