将homePage视图链接到其他视图

Question

我正在尝试将我的主页视图链接到其他视图，但它不起作用，我也尝试只使用一个视图，但它仍然不能工作，我也不知道如何将多个视图连接到一个URL中

app/views.py

from django.http import HttpResponse, HttpResponseRedirect
from django.shortcuts import redirect
from django.shortcuts import render
from homePage.forms import SignInForm,DropUsaMessage
# Create your views here.
def homePage(request):
    sign_in_detail=SignIn
    message_detail=DropUsaMessage
    return render(request, "index.html",{"form":sign_in_detail,"forms":message_detail})

def SignIn(request):
    sign_in_detail=SignInForm()
    if request.method == 'POST':
        sign_in_detail = SignInForm(request.POST)
        if sign_in_detail.is_valid():
            return render(request, "index2.html",{"form":sign_in_detail})
    else:
        sign_in_detail = SignInForm()
        # "form":sign_in_detail
    return render(request, "index.html",{})

def Contact(request):
    message_detail=DropUsaMessage()
    if request.method == 'POST':
        message_detail = DropUsaMessage(request.POST)
        if message_detail.is_valid():
            return homePage(request)
    else:
        message_detail = DropUsaMessage()
        # "forms":message_detail
    return render(request, "index.html",{"forms":message_detail})

app/urls.py

from django.urls import path
from . import views

urlpatterns=[
        path('', views.homePage),
]

app/forms.py

from django import forms
from django.core import validators

class SignInForm(forms.Form):
    email=forms.EmailField(widget=forms.EmailInput(attrs={"class": 'form-control',"placeholder":'Enter E-mail',"id": 'exampleInputEmail1'}))
    password=forms.CharField(widget=forms.PasswordInput(attrs={"class":'form-control',"placeholder":'Enter Password',"id":'exampleInputPassword1'}))

class DropUsaMessage(forms.Form):
    name = forms.CharField(widget=forms.TextInput(attrs={"class":'form-control',"placeholder":'Your Name'}))
    email = forms.EmailField(widget=forms.EmailInput(attrs={"class": 'form-control',"placeholder":'Your E-mail',"id": 'exampleInputEmail1'}))
    phone = forms.IntegerField(widget=forms.NumberInput(attrs={"class":'form-control',"placeholder":'Your Phone Number'}))
    message = forms.CharField(widget=forms.Textarea(attrs={"class":'form-control',"placeholder":'Type Your Message',"style":'width:100%; height: 150px'}))

index.html

      <div class="container-fluid">

        <div class="row">
          <div class="col-md-8">
            <img src="{% static 'img/sampleImage.jpg' %}" width="100%" height="100%" class="d-inline-block align-top" alt="">
          </div>
          <div class="col-md-4">
            <form method="POST">
              {% csrf_token %}
              {{ form }}
              <div class="form-check">
                  <span class="fpswd">Forgot <a href="#">password?</a></span>
              </div>
              <button type="submit" class="btn btn-primary" name="SignIn">Submit</button>
            </form>



          </div>
        </div>
      </div>

<div class="container contact-form">
              <form  method="post">
                      <h3>Drop Us a Message</h3>
                              {% csrf_token %}
                              {{ forms }}<br><br>
                              <div class="form-group">
                                  <input type="submit" name="SendMessage" class="btnContact" value="Send Message" />
                              </div>



              </form>
      </div>

signin字段没有出现。在django-调试-工具栏中显示了一个长地址。

Answer 1

给您的URL模式命名如下：

urlpatterns=[
        path('', views.homePage, name='home'),
]

然后，在模板中，您可以使用Jinja引用这些名称如下。

<a href="{% url 'home' %}">Home</a>

您可以从DjangoProject站点教程获得一些关于链接的帮助。

更新：

您需要创建一个Navbar (导航栏)。然后，您可以使用主页中的URLS调用所有页面。喜欢

Home | Services | Portfolio 

您需要为每个页面创建具有名称的urlpatterns，然后您可以像这样使用它。

<ul><li><a href="{% url 'home' %}">Home</a></li> 
<ul><li><a href="{% url 'services' %}">Services</a></li>
<ul><li><a href="{% url 'portfolio' %}">Portfolio</a></li>. 

因此，所有的页面将链接到您的主页，您可以导航。

为此，您需要在urls.py中分别创建3个视图，如下所示：

urlpatterns=[
        path('', views.homePage, name='home'),
        path('services/', views.servicePage, name='services'),
        path('portfolio/', views.portfolioPage, name='portfolio'),
]

Answer 2

一个URL上不能有多个视图。一个URL映射到一个视图。
