Django HTML模板未从模型的通用视图加载

介绍

我目前正在研究该项目的一小部分，以了解有关Django ORM的更多信息并显示单个对象。使用通用视图保持代码干净。（我是Django框架的新手）

目标

本文的目的是显示有多少用户写了一篇文章。例如，我总共有4条文章。我需要显示每个用户写了多少篇文章。

我的控制台输出：

我在HTML模板上的输出：

问题

我不明白为什么控制台输出正确，但是我的HTML模板没有显示结果。请帮助我理解为什么这样做！！如果有类似的帖子让我知道！我一直到处都在寻找答案，但是我无法在互联网上找到答案。

码

views.py

from django.views.generic import ListView
from .models import Article
from django.contrib.auth import get_user_model


class ArticleListView(ListView):
    model = Article
    template_name = 'article_list.html'
    context_object_name='article_list'
    queryset=Article.objects.order_by('-date')

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)        
        users = get_user_model().objects.all()
        context["users"] = users
        articles = Article.objects.all()
        for user in users:
            article_count = articles.filter(author__exact=user).values('author').count()
            # works with and without str() function
            context['article_count'] = str(article_count)
            # My console output is correct
            print(str(user) + ': ' + str(articles.filter(author__exact=user).values('author').count()))

        return context

models.py

from django.contrib.auth import get_user_model
from django.db import models
from django.urls import reverse


class Article(models.Model):
    title = models.CharField(max_length=255)
    body = models.TextField()
    date = models.DateTimeField(auto_now_add=True)
    author = models.ForeignKey(
        get_user_model(),
        on_delete=models.CASCADE,
    )

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('article_detail', args=[str(self.id)])

article_list.html

{% extends 'base.html' %}

{% block title %}Articles{% endblock title %}

{% block content %}

   <!-- This is for checking if the articles exist. Nothing to worry here. Output is 4 -->
  {% if article_count > 0 %}
    <p>{{article_count}} There are articles in this list</p>
  {% else %}
   <p>There are no articles in this list</p>
  {% endif %}

  <!-- Main source of the problem!! -->
  {% for user in users %}
    <p>{{user}} = {{article_count}}</p>
  {% endfor %}

  <!-- Displays data from database. Nothing to worry here. -->
  {% for article in article_list %}
    <div class="card">
      <div class="card-header">
        <span class="font-weight-bold">{{ article.title }}</span> &middot;
        <span class="text-muted">by {{ article.author }} | {{ article.date }}</span>
      </div>
      <div class="card-body">
        {{ article.body }}
      </div>
      <div class="card-footer text-center text-muted">
        <a href="{% url 'article_edit' article.pk %}">Edit</a> |
