将用户重定向到其他模型中的某人配置文件时出错

Question

我想将用户重定向到问题模型中的个人资料页面，当用户在问题模型的用户名中单击URL时，我希望该URL将用户重定向到该问题的作者到他/她的public_profile页面，例如Facebook您可以在他/她发布某些内容时单击他的名字来访问某人的个人资料，我尝试使用此方法，但它给我带来了一个错误：反向'public_profile'带有参数'（'''，）'找不到。 个模式尝试：['userProfile/

（

我的观点：

@login_required(login_url='login')
def index(request):
    query = request.GET.get('q', None)
    list_of_question = Question.objects.all()
    if query is not None:
        list_of_question = Question.objects.filter(
            Q(title__icontains=query) |
            Q(category__name__icontains=query)
        )
    unread_notifications = 
    Notification.objects.filter(user=request.user, 
    is_read=False).count()

    paginator = Paginator(list_of_question, per_page=15)
    context = [
        {
             'unread_notifications':unread_notifications,
             'list_of_question':list_of_question,
             'paginator':paginator
       }
    ]
    return render(request, 'index.html', context)

def profile(request, pk):
    profiles = Profile.objects.filter(user=request.user)
    questions = Question.objects.filter(user=request.user)
    context = {
        'profiles':profiles,
        'questions':questions
    }
    return render(request, 'profile.html', context)

def public_profile(request, slug):
    contents = get_object_or_404(Profile, slug=slug)
    profiles = Profile.objects.filter(user=contents)
    context = {
        'contents':contents,
        'profiles':profiles
    }
    return render(request, 'public_profile.html', context)

我的模型

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    profile_image = models.ImageField(upload_to='avatar', blank=True, null=True, 
    default='static/default.jpg')
    stories = RichTextField(blank=True, null=True)
    twitter = models.URLField(max_length=300, blank=True, null=True)
    website = models.URLField(max_length=300,blank=True, null=True)
    city = models.CharField(max_length=50, blank=True, null=True)
    location = models.CharField(max_length=80, blank=True, null=True)
    slug = models.SlugField(unique=True, max_length=200)

    def save(self, *args, **kwargs):
        self.slug = slugify(self.user)
        super(Profile, self).save(*args, **kwargs)

    def __str__(self):
        return str(self.user)

class Question(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    title = models.CharField(max_length=100, blank=False, null=False)
    body = RichTextField(blank=False, null=False) 
    category = models.ForeignKey(Category, on_delete=models.CASCADE)
    slug = models.SlugField(unique=True, max_length=200)

    def save(self, *args, **kwargs):
        self.slug = slugify(self.title)
        super(Question, self).save(*args, **kwargs)

    def __str__(self):
        return str(self.title)

Answer 1

错误是试图告诉您Django试图致电 public_profile ，但需要一些sl。这是因为profile在模板上下文中没有。您需要更改＆lt; a href =“ {％url'public_profile'profile'profile'profile.slug％}”＆gt;使用＆lt; a href =“ {％url url'public_profile'问题.slug％}“＆gt;

Answer 2

您应该更改profile.slug toed.user.profile.slug

在模板中尝试此操作：

<div class="container">
    <div class="row justify-content-center">
        {% for question in list_of_question reversed %}
        <div class="col-md-4">
            <div class="card my-3">
                <div class="card-header">
                <p class="card-title">
                <a href="{% url'Public_Profile' question.user.profile.slug %}">
                    {{question.user.username.upper}}
                </a></p>
                </div>
                <div class="card-body">
                    <a href="{% url 'view-Question' question.slug %}" style="text-decoration: none;">
                        <p class="card-title">{{question.title}}</p>
                    </a>
                    <h5>{{question.category}}</h5>
                </div>
            </div>
        </div>
        {%endfor%}
    </div>
</div>

Answer 3

在模板

<p class="card-title">
 <a href="/profile/{{question.user}}">
   {{question.user.username.upper}}
 </a>
</p>

视图中：

def profile(request, pk):
    profiles = Profile.objects.get(user=pk)
    questions = Question.objects.filter(user=pk)
    context = {
        'profiles':profiles,
        'questions':questions
    }
    return render(request, 'profile.html', context)
