尝试单击“赞”按钮时出现错误 此页面无法正常工作 HTTP 错误 405

Question

我是 Django 新手，正在尝试在博客应用程序中实现喜欢和不喜欢选项。

我有一个问题，一旦任何登录用户单击“赞”按钮，浏览器就会给出 HTTP ERROR 405

一旦用户点击 Like 按钮，它就会重定向到 PostDetailView (post_detail)

我还在 post_detail.html 页面中添加了如下形式的 POST 方法

view.py

class PostDetailView(DetailView):
    model = Post
    template_name = 'blog/post_detail.html'
    
    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        data = get_object_or_404(Post, id=self.kwargs['pk'])
        total_likes = data.total_likes()
        liked = False
        if data.likes.filter(id=self.request.user.id).exists():
            liked = True
        else:
            pass
        context["total_likes"] = total_likes
        context["liked"] = liked
        return context
        
def LikeView(request,pk):
    if request.method == 'POST':
        post = get_object_or_404(Post, id=request.POST.get('post_id'))
        liked = False
        if post.likes.filter(id=request.user.id).exists():
            post.likes.remove(request.user)
        else:
            post.likes.add(request.user)
            liked = True
        post.likes.add(request.user)
        return HttpResponseRedirect(reverse('post_detail', args=[str(pk)]))

post_detail.html

{% extends 'blog/base.html' %}

{% block content %}
    {% csrf_token %}
    <article class="media content-section">
        <img class="rounded-circle article-img" src="{{ object.author.profile.image.url }}">

            </div>
            <h2 class="article-title">{{ object.title }}</h2>
            <p class="article-content">{{ object.content|urlize }}</p>
            {% if object.author == user %}
                    <div>
                        <a class="btn sm btn btn-secondary mb-1" href="{% url 'post_update' object.id %}">Update</a>
                        <a class="btn sm btn btn-danger mb-1" href="{% url 'post_delete' object.id %}">Delete</a>
                    </div>
            {% endif %}
            
            <br/><br/>
            <form action="{% url 'like_post' object.id %}" 
                method="POST">
                {% csrf_token %}
                {% if liked %}
                    <button class="btn btn-danger btn-sm" type="submit", name "post_id", value={{post.id}}>Unlike
                    </button>
                {% else %}
                    <button class="btn btn-primary btn-sm" type="submit", name "post_id", value={{post.id}}>Like
                    </button>
                {% endif %}
                 - {{ total_likes }}
            </form>

        </div>
    </article>
    
{% endblock  %}

urls.py

urlpatterns = [
    path('', PostListView.as_view(), name='home'),
    path('user/<str:username>', UserPostListView.as_view(), name='user_post'),
    path('post/<int:pk>/', PostDetailView.as_view(), name='post_detail'),
    path('post/<int:pk>/update', PostUpdateView.as_view(), name='post_update'),
    path('post/<int:pk>/delete', PostDeleteView.as_view(), name='post_delete'),
    path('post/new/', PostCreateView.as_view(), name='post_create'),
    path('about/', views.about, name='about'),
    path('contact/', views.contactView, name='contact'),
    path('success/', views.successView, name='success'),
    path('post/<int:pk>/', views.LikeView, name='like_post'),
]

Answer 1

在你的 urls.py “like_post”和“post_detail” 具有相同的模式。我认为当您发布到此网址时，您的代码会选择“post_detail”而不是“like_post”。

urlpatterns = [
    path('post/<int:pk>/like', views.LikeView, name='like_post'),
]

可以解决你的问题
