Question

我正在django制作一个网站，在我的主页上，我想显示我最近的博客文章列表，下面几个街区我想制作一个简单的联系表格。博客和联系表单独工作正常。但我希望将它们包含在同一页面中（显然在同一个网址中）。

views.py是：

from .forms import NameForm

def get_name(request):
    if request.method == 'POST':
        form = NameForm(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/thanks/')
    else:
        form = NameForm()
    return render(request, 'personal/index.html', {'form': form})

如果你想查看forms.py，那么：

from django import forms

class NameForm(forms.Form):
    your_name = forms.CharField(label='Your name', max_length=100)

我主页的urls.py中的urlpattern是：

urlpatterns = [
    url(r'^$', ListView.as_view(
                                queryset=Post.objects.all().order_by("-date")[:2],
                                template_name="personal/index.html")),
    url(r'^$', views.get_name, name='contact'),
]

使用此urlpatter，博客文章列表完美显示但联系表单未显示。但是，下面的urlpattern联系表单显示但博客文章没有显示。

urlpatterns = [
    url(r'^$', views.get_name, name='contact'),
    url(r'^$', ListView.as_view(
                                queryset=Post.objects.all().order_by("-date")[:2],
                                template_name="personal/index.html")),
]

我想让这两个内容显示在同一页面中。请帮我。如果您需要更多信息，请告诉我们。

Answer 1

同一网址不可能有多个视图。每个网址只能有一个视图。

在这种情况下，最简单的解决方法是更新您的get_name视图，使其包含模板上下文中的帖子。

def get_name(request):
    if request.method == 'POST':
        form = NameForm(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/thanks/')
    else:
        form = NameForm()
    post_list = Post.objects.all().order_by("-date")[:2]
    return render(request, 'personal/index.html', {'form': form, 'post_list': post_list})

然后删除使用ListView的网址格式，以便get_name处理请求。

虽然您不能直接执行此操作，但是您可以在views.py中考虑您的函数以某种方式处理请求，即当它从一个模型收到发布请求时，仅初始化相应模型的表单。为此，您需要为按钮分配一个名称。参见下面的代码-

def SignUpLogin(request):
    message = ""
    Login_message = ""
    print(request.POST)
    if request.method == 'POST':
        if request.POST.get('UserForgotPassword') == 'Sign Up':
            form_SignUP_Login = LoginForm()
            print("POST request received")
            print(request.POST)
            form_SignUP=SignUpForm(request.POST)
            print(form_SignUP)
            if form_SignUP.is_valid():
                if request.POST["Password"] != request.POST["Confirm_Password"]:
                    message = "* Passwords do not match"
                    #raise forms.ValidationError(('Passwords do not match'), code="PasswordNotMatched")
                else:
                    try:
                        user = User.objects.get(username=request.POST["Username"])
                        context= {'form': form_SignUP, 'error':'* Username already taken. Please try different username.'}
                        return render(request, 'User/SignUp.html', context)
                    except User.DoesNotExist:
                        user = User.objects.create_user(request.POST["Username"], request.POST["Email"], request.POST["Password"])
                        user.first_name = request.POST["First_Name"]
                        user.last_name = request.POST["Last_Name"]
                        user.save()
                        form_SignUP = SignUpModel(Username = request.POST["Username"], First_Name = request.POST["First_Name"], Last_Name = request.POST["Last_Name"], Email = request.POST["Email"],  Company_Name = request.POST["Company_Name"], Address = request.POST["Address"], Password = make_password(request.POST["Password"]), Confirm_Password = make_password(request.POST["Confirm_Password"]), Phone_Number = request.POST["Phone_Number"])
                        form_SignUP.save()

                        #queryset = SignUpModel.objects.get(Username = request.POST["Username"])
                        #queryset.Password = "pwd_removed"
                        #queryset.Confirm_Password = "pwd_removed"
                        #queryset.save()
                        #send_email_to_host(request.POST["First_Name"], request.POST["Family_Name"], request.POST["Number_Of_Adults"], request.POST["Number_Of_Kids"], request.POST["Email"])
                        return redirect(HomePage)

        elif request.POST.get('UserLogin') == 'Login':
            form_SignUP = SignUpForm()
            form_SignUP_Login=LoginForm(request.POST)
            if form_SignUP_Login.is_valid():
                user = authenticate(username=request.POST["Username"], password=request.POST["Password"])
                if user is not None:
                    print("User authenticated")
                    return redirect(HomePage)
                else:
                    print("User not authenticated")
                    form_SignUP_Login = LoginForm()
                    Login_message = "Username and password combination is not correct"

        elif request.POST.get('UserForgotPassword') == 'Forgot Password':
            form_SignUP = SignUpForm()
            form_SignUP_Login = LoginForm()


    else:
        form_SignUP = SignUpForm()
        form_SignUP_Login = LoginForm()

    return render(request, 'User/SignUp.html', {'form' : form_SignUP, "error":message,'form_login' : form_SignUP_Login, "error_login":Login_message})
