在 Django 中，我无法从另一个页面显示索引中的表单。我只看到按钮，但看不到文本框

问题描述 投票：0回答：1

我想直接在索引

.html
页面（主页）查看注册表。在index.html中，我想显示
register.html
。

注册表单在registration/register.html 中创建。我在index.html中使用以下方式调用它：

{% block content %}
{% include 'registration/register.html' %}
{%endblock%}

在

urlpatterns
的
App1/views.py
中，我使用：

path("register_request", views.register_request, name='register_request')

问题是在index.html上我看到了表单按钮，但看不到它的文本框（用户名、电子邮件、密码）。

我不明白我错在哪里。你能告诉我我做错了什么吗？你能告诉我代码如何修复它吗？

这是

App1
:

App1
.migrations
.static
.templates
..index.html
..registration
...register.html

index.html

{% load static %}

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>University</title>

<body>

  {% block content %}
  {% include 'registration/register.html' %}
  {%endblock%}

</body>
</html>

App1/templates/registration/register.html

<!--Register--> 
<div class="container py-5">
    <h1>Register</h1>
    <form method="POST">
        {% csrf_token %}
        {{ register_form.as_p }}                    
        <button class="btn btn-primary" type="submit">Register</button>
    </form>
    <p class="text-center">If you already have an account, <a href="/login">login</a> instead.</p>
</div>

App1/forms.py

from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User

# Create your forms here.

class NewUserForm(UserCreationForm):
    email = forms.EmailField(required=True)

    class Meta:
        model = User
        fields = ("username", "email", "password1", "password2")

    def save(self, commit=True):
        user = super(NewUserForm, self).save(commit=False)
        user.email = self.cleaned_data['email']
        if commit:
            user.save()
        return user

App1/urls.py

from django.urls import path
from . import views

urlpatterns=[
  path('', views.index, name='index'), 
  path("register_request", views.register_request, name='register_request'),
  ]

App1/views.py

from .forms import NewUserForm
from django.contrib import messages
from django.contrib.auth.decorators import login_required

def index(request):
    """View function for home page of site."""
    return render(request, 'index.html')

def register_request(request):
    if request.method == "POST":
        form = NewUserForm(request.POST)
        if form.is_valid():
            user = form.save()
            login(request, user)
            messages.success(request, "Registration successful." )
            return redirect("index.html")
        messages.error(request, "Unsuccessful registration. Invalid information.")
    form = NewUserForm()
    return render (request=request, template_name="registration/register.html", context={"register_form":form})
    #NO: return render(request, "registration/register.html",{"register_form":form})

我的网站（项目）

mysite/urls.py

from django.contrib import admin
from django.urls import path, include
from django.contrib.auth import views as auth_views
from django.contrib.auth.views import LoginView

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('App1.urls')),

mysite/setting.py

TEMPLATES = [
    {
        ....
        #NO: "DIRS" :  [ BASE_DIR  /  "templates" ],
        'DIRS': ["templates"], 
 [

STATIC_DIR = os.path.join(BASE_DIR,"static")
STATIC_URL = '/static/'
STATICFILES_DIRS = [STATIC_DIR,]

在

models.py
我什么也没写。

python python-3.x django django-forms

问题在于您如何呈现注册表单。由于您希望表单位于索引页上，因此不需要单独的视图 (

register_request
)。删除该视图并直接在您的 
index
视图中处理表单处理。我在下面的代码片段中做了一些调整。

# In App1/views.py
from .forms import NewUserForm
from django.contrib import messages
from django.contrib.auth.decorators import login_required
from django.shortcuts import render, redirect

def index(request):
    if request.method == "POST":
        form = NewUserForm(request.POST)
        if form.is_valid():
            user = form.save()
            login(request, user)
            messages.success(request, "Registration successful.")
            return redirect("index")
        else:
            messages.error(request, "Unsuccessful registration. Invalid information.")
    else:
        form = NewUserForm()

    return render(request, 'index.html', {'register_form': form})

删除

register_request
中的
App1/urls.py
路径：

# In App1/urls.py
from django.urls import path
from . import views

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

这些更改应在您的索引页面上正确显示注册表单。
