【问题描述】：
我一直在尝试的是单击帖子的作者（创建帖子的用户）我希望它将我重定向到该用户的个人资料，例如在 Instagram 中，当您单击帖子顶部的用户时-它会将您重定向到他们的个人资料。每次我这样做而不是看到帖子的作者个人资料时，我都会看到登录的用户个人资料。我认为views.py 文件或base.html 中有问题。
views.py
def profile(request, pk=None):
if pk:
user = get_object_or_404(User, pk=pk)
else:
user = request.user
args = {'user': user}
return render(request, 'profile.html', args)
def home(request):
created_posts = Create.objects.all().order_by("-added_date")
return render(request, 'base.html', {"created_posts": created_posts})
def create(request):
if request.method == 'POST':
created_date = timezone.now()
header1 = request.POST['header']
content1 = request.POST['content']
user = request.user
created_obj = Create.objects.create(added_date=created_date, title=header1, content=content1, user=user)
created_obj.save()
print('create created')
return redirect('home')
else:
print('create not created')
return render(request, 'create.html')
models.py
class Create(models.Model):
added_date = models.DateTimeField()
title = models.CharField(max_length=200)
content = models.CharField(max_length=200)
user = models.ForeignKey(User, related_name='user', on_delete=models.CASCADE, default=1)
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
image = models.ImageField(default='default.jpg', upload_to='profile_pics')
def __str__(self):
return f'{self.user.username} Profile'
urls.py
urlpatterns = [
path('', views.home, name='home'),
path('profile', views.profile, name='profile'),
path('profile/<int:pk>/', views.profile, name='profile_pk'),
path('create', views.create, name='create'),
]
profile.html（显示用户的个人资料）
{% extends 'home.html' %}
{% block body%}
<div class="content-section">
<div class="media">

<div class="media-body">
<h2 class="account-heading">{{ user.username }}</h2>
<p class="text-secondary">{{ user.email }}</p>
</div>
</div>
</div>
{% endblock %}
base.html（使用用户名显示所有用户的帖子）
{% extends 'home.html' %}
{% block body %}
<ul action="{% url 'create' %}" class="container-sm list-group" style="margin-top: 200px;">
{% for created_post in created_posts %}
<li class="list-group-item">{{ created_post.title }}

【问题讨论】：
-
找到解决方案的一种简单方法是使用调试器查看您在
views.py中收到的pk的值。 -
@ansuman 如何使用调试器？
-
插入
import pdb; pdb.set_trace()你想暂停执行的地方，检查你的终端应该有这样的-> (Pdb)输入pk。它应该向您显示收到的 pk 值。 -
请注意，这是 python 调试器仅适用于 python 文件，因为有多种调试方式，例如使用 IDE：stackoverflow.com/questions/1118183/…
-
@ansuman 当我放 pk 时它给了我这个错误 *** NameError: name 'pk' is not defined
