Django 视图返回 POST 而不是 GET 请求

Question

所以我有这些使用 POST 请求进行注册和登录的工作视图，它们都返回 profile.html。

问题是登录和注册视图在我提交表单（根据 cmd）时返回一个 POST 到登录或注册 url，以运行必要的功能。 这意味着它只是渲染 profile.html，而不是运行 ITS 视图功能。

我如何提交表单向配置文件视图发送 GET，同时仍然让他们为各自的功能发送 POST。

def log_in(request):
    if request.method == 'POST':
        form = log_form(request.POST)
        if form.is_valid():
            username = form.cleaned_data['username']
            password = form.cleaned_data['password']
            user = authenticate(request, username=username, password=password)
            if user is not None:
                print("user exists")
                login(request, user)
                return render(request, 'profile.html')
            else:
                print("user does not exist")
                print(form.errors)
                return render(request, 'login.html', {
                    'form2': log_form
                })
        else:
            return render(request, 'login.html', {
            'form2': log_form
            })
    else:
        return render(request, 'login.html', {
            'form2': log_form
        })


def profile(request, username): 
    if request.method == 'GET':
        user = Users.objects.get(username=username)
        interests = []
        interest_list = Interests.objects.filter(member=user)#i got 5 objs here
        for i in interest_list:
            interests.append(i.item)
            print('added interest')
        info = Bios.objects.get(author=user)
        return render(request, 'profile.html', {
            'user': user,
            "interests": interests,
            'info': info
        })

urlpatterns = [
    path('reg/', views.register, name='register'),
    path('log/', views.log_in, name='login'),
    path('profile/<str:username>/', views.profile, name='profile'),

登录表单：

<form method='POST' action="{%url 'login' %}">
                        {% csrf_token %}
                        <p>Username: {{form2.username}}</p>

                    </form>

注册表：

<form method='POST' action="{% url 'register' %}">
                        {% csrf_token %}
                        <p>Username: {{form.username}}</p>
                        <p>Email:    {{form.email}}</p>
                        <p>Password: {{form.password}}</p>
                        <p>Phone:    {{form.phone}}</p>

                        {{form.errors}}
                        {% if form.errors %}
                            {% for field in form %}
                                {% for error in field.errors %}
                                    <p>
                                        <strong>{{ error|escape }}</strong>
                                    </p>
                                {% endfor %}
                            {% endfor %}
                            {% for error in form.non_field_errors %}
                                <p>
                                    <strong>{{ error|escape }}</strong>

登录页面应该被访问两次：当用户被重定向到它时，使用 GET，以及再次当用户发送填写的表单时，这次使用 POST。您的视图逻辑应处理两种类型的申请：

def user_login(request):
    if request.POST:
        form = UserForm(request.POST) # note that I renamed your form
        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(username=username, password=password)
        if user is not None:
            if user.is_active:
                login(request, user)
                return redirect('profile', kwargs={username=user})
    else: # request is GET
        form = UserForm()
    return render(request, 'login.html', {'form': form})

@require_GET()
def profile(request, username): 
    user = Users.objects.get(username=username)
    interests = Interests.objects.filter(member=user).values_list('item', flat=True)       
    info = Bios.objects.get(author=user)
    context = {
        'user': user,
        "interests": interests,
        'info': info
    }
    return render(request, 'profile.html', context)

我还稍微更改了配置文件视图，以使用我认为是基于 Django 函数的视图中的最佳实践。
