如何在Python MVC应用程序中从数据库获取数据

Question

模型

class URL_monitor(models.Model):
    url = models.TextField(unique=True, verbose_name='URL')
    interval = models.PositiveIntegerField(verbose_name='Interval (in seconds)')


    def __str__(self):
        return self.url

    def get_absolute_url(self):
        return reverse('index')

查看

def IndexView(request):
    urls = URL_monitor.objects.all()
    response = requests.get(urls)
    status = response.status_code
    context = {
        'urls' : urls,
        'status' : status,

    }
    return render(request, 'index.html', context)

模板

      {% if urls %}
          {% for url in urls %}
              <p>Status: {{ status }} {{ url.url }} <a href="{% url 'delete_url' url.pk %}">Delete</a></p>
          {% endfor %}
      {% else %}
          <p>No URL's added, <a href="{% url 'add_url' %}">add some</a></p>
      {% endif %}

我只想从模型中获取一个url并为其获取状态代码。我在数据库中的url字段具有一个值：http://google.com/
