Question

我对Django很陌生，遇到了一个问题。我什至不确定这是否是一个愚蠢的问题。我想测试我的主视图是否包含指向主题视图的链接，但是尽管一切就绪，但测试仍然失败。感谢任何帮助。它显示以下错误

Traceback (most recent call last):
  File "/home/abc/Desktop/python-environments/second/tutorial/myproject/boards/tests.py", line 26, in test_home_view_contains_link_to_topics_page
self.assertContains(self.response, 'href="{0}"'.format(board_topics_url))
  File "/home/abc/Desktop/python-environments/second/lib/python3.5/site-packages/django/test/testcases.py", line 369, in assertContains
self.assertTrue(real_count != 0, msg_prefix + "Couldn't find %s in response" % text_repr)
AssertionError: False is not true : Couldn't find 'href="/boards/1/"' in response

这是我的文件

urls.py

from django.urls import path
from . import views


app_name = 'boards'
urlpatterns = [
path('', views.home, name='home'),
path('<int:d>/', views.topics, name='topics'),

]

views.py

from django.shortcuts import render, get_object_or_404
from .models import Board, topic


def home(request):
    boards = Board.objects.all()
    return render(request, 'boards/index.html', {'boards': boards})

def topics(request, d):
    board = get_object_or_404(Board, id=d)
    return render(request, 'boards/topics.html', {'boards': board})

index.html

{% load static %}<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Boards</title>
    <link rel="stylesheet" href="{% static 'boards/css/bootstrap.min.css'     %}">
  </head>
  <body>
    <div class="container">
      <ol class="breadcrumb my-4">
        <li class="breadcrumb-item active">Boards</li>
      </ol>
      <table class="table">
        <thead class="thead-inverse">
          <tr>
            <th>Board</th>
            <th>Posts</th>
            <th>Topics</th>
            <th>Last Post</th>
          </tr>
        </thead>
        <tbody>
          {% for board in boards %}
            <tr>
              <td>
                  <a href = "{% url 'boards:topics' board.id %}"> {{board.Name }}</a>
                <small class="text-muted d-block">{{ board.description}}</small>
              </td>
              <td class="align-middle">0</td>
              <td class="align-middle">0</td>
              <td></td>
            </tr>
          {% endfor %}
        </tbody>
      </table>
    </div>
  </body>
</html>

最后是tests.py

from django.test import TestCase
from django.urls import reverse, resolve
from .models import Board
from .views import topics, home


class HomeTests(TestCase):

    def setUp(self):
        self.board = Board.objects.create(Name='Python',description='Python discussion board')
        self.response = self.client.get(reverse('boards:home'))

def test_home_view_status_code(self):
    self.assertEquals(self.response.status_code, 200)

def test_home_url_resolves_to_home_view(self):
    view = resolve('/boards/')
    self.assertEquals(view.func, home)

def test_home_view_contains_link_to_topics_page(self):
    board_topics_url = reverse('boards:topics', kwargs={'d': self.board.id})
    self.assertContains(self.response, 'href="{0}"'.format(board_topics_url))

Answer 1

self.assertContains（self.response， 'href =“ {0}”'。format（board_topics_url））

您是否忘记了=周围的空格？无论如何，您都可以在浏览器中打开页面并检查其html代码。
