TemplateDoesNotExist 在 /account/

Question

我尝试让我的网址更具动态性，但最终破坏了一些东西。我可以用我的一生来解决它！任何帮助将不胜感激。唯一有效的 URL 是我的登录和注销模板。我明白为什么这些都有效，但是我的其余 URL 做错了什么？

这是我收到的回溯：

TemplateDoesNotExist: accounts:home

以下是我的看法：

from django.shortcuts import render, redirect
from django.urls import reverse
from accounts.forms import (
    RegistrationForm,
    EditProfileForm
)
from django.contrib.auth.models import User
from django.contrib.auth.forms import (
    UserChangeForm,
    PasswordChangeForm
)
from django.contrib.auth import update_session_auth_hash
from django.contrib.auth.decorators import login_required

# Create your views here.

def home(request):
    name = 'Matthew Zayas'
    args = {'myName': name}
    return render(request, 'accounts:home')

def register(request):
    if request.method =='POST':
        form = RegistrationForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect(reverse('accounts:home'))
    else:
        form = RegistrationForm()

        args = {'form': form}
        return render(request, 'accounts:register', args)

def view_profile(request):
    args = {'user': request.user}
    return render(request, 'accounts:view_profile', args)

def edit_profile(request):
    if request.method == 'POST':
        form = EditProfileForm(request.POST, instance=request.user)

        if form.is_valid:
            form.save()
            return redirect('accounts:view_profile')
    else:
        form = EditProfileForm(instance=request.user)
        args = {'form': form}
        return render(request, 'accounts:edit_profile', args)

def change_password(request):
    if request.method == 'POST':
        form = PasswordChangeForm(data=request.POST, user=request.user)

        if form.is_valid():
            form.save()
            update_session_auth_hash(request, form.user)
            return redirect('accounts:view_profile')
        else:
            return redirect('accounts:change_password')
    else:
        form = PasswordChangeForm(user=request.user)
        args = {'form': form}
        return render(request, 'accounts:change_password', args)

我的网址：

from django.conf.urls import url
from . import views
from django.contrib.auth.views import (
        login,
        logout,
        password_reset,
        password_reset_done,
        password_reset_confirm,
        password_reset_complete
)

urlpatterns = [
    url(r'^$', views.home, name='home'),
    url(r'^login/$', login, {'template_name': 'accounts/login.html'}, name='login'),
    url(r'^logout/$', logout, {'template_name': 'accounts/logout.html'}, name='logout'),
    url(r'^register/$', views.register, name='register'),
    url(r'^profile/$', views.view_profile, name='view_profile'),
    url(r'^profile/edit$', views.edit_profile, name='edit_profile'),
    url(r'^change-password/$', views.change_password, name='change_password'),
    url(r'^reset-password/$', password_reset, {'template_name': 'accounts/reset_password.html'}, name='reset_password'),
    url(r'^reset-password/done/$', password_reset_done, name='password_reset_done'),
    url(r'^reset-password/confirm/(?P<uidb64>[0-9A-Za-z]+)-(?P<token>.+)/$', password_reset_confirm, name='password_reset_confirm'),
    url(r'^reset-password/complete$', password_reset_complete, name='password_reset_complete')
]

这是我的中间件：

import re

from django.conf import settings
from django.urls import reverse
from django.shortcuts import redirect
from django.contrib.auth import logout

EXEMPT_URLS = [re.compile(settings.LOGIN_URL.lstrip('/'))]
if hasattr(settings, 'LOGIN_EXEMPT_URLS'):
    EXEMPT_URLS += [re.compile(url) for url in settings.LOGIN_EXEMPT_URLS]

class LoginRequiredMiddleware:

    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        response = self.get_response(request)
        return response

    def process_view(self, request, view_func, view_args, view_kwargs):
        assert hasattr(request, 'user')
        path = request.path_info.lstrip('/')    
        url_is_exempt = any(url.match(path) for url in EXEMPT_URLS)

        if path == reverse('accounts:logout').lstrip('/'):
            logout(request)

        if request.user.is_authenticated() and url_is_exempt:
            return redirect(settings.LOGIN_REDIRECT_URL)
        elif request.user.is_authenticated() or url_is_exempt:
            return None
        else:
            return redirect(settings.LOGIN_URL)

render 函数接受两个必需的参数。

来自文档，

render(request, template_name, context=None, content_type=None, status=None, using=None)[来源]

将给定的模板与给定的上下文字典结合起来，并返回一个带有渲染文本的 HttpResponse 对象。

必填参数

请求

用于生成此响应的请求对象。

模板名称

要使用的模板的全名或模板名称的序列。如果给定一个序列，将使用第一个存在的模板。有关如何找到模板的更多信息，请参阅template loading documentation。

所以，你需要在函数中添加template_name，而不是url的命名空间。

编辑您的观点，

def home(request):
    name = 'Matthew Zayas'
    args = {'myName': name}
    #add the full name of the template and the 
    #context variables you want to add.
    return render(request, 'accounts/home.html', args)

def register(request):
    if request.method =='POST':
        form = RegistrationForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect(reverse('accounts:home'))
    else:
        form = RegistrationForm()
    args = {'form': form}
    #here tooo..
    return render(request, 'accounts/register.html', args)

def view_profile(request):
    args = {'user': request.user}
    #same here..
    return render(request, 'accounts/view_profile.html', args)

def edit_profile(request):
    if request.method == 'POST':
        form = EditProfileForm(request.POST, instance=request.user)

        if form.is_valid:
            form.save()
            return redirect('accounts:view_profile')
    else:
        form = EditProfileForm(instance=request.user)
    args = {'form': form}
    return render(request, 'accounts/edit_profile.html', args)

def change_password(request):
    if request.method == 'POST':
        form = PasswordChangeForm(data=request.POST, user=request.user)

        if form.is_valid():
            form.save()
            update_session_auth_hash(request, form.user)
            return redirect('accounts:view_profile')
        else:
            return redirect('accounts:change_password')
    else:
        form = PasswordChangeForm(user=request.user)
    args = {'form': form}
    #same thing here too
    return render(request, 'accounts/change_password.html', args)

Answer 2

您似乎忘记在视图中包含反向功能。

你的代码

def home(request):
name = 'Matthew Zayas'
args = {'myName': name}
return render(request, 'accounts:home')

要修改的是

def home(request):
name = 'Matthew Zayas'
args = {'myName': name}
return render(request, reverse('accounts:home'))

希望这会有所帮助。

转到项目目录中的“settings.py”文件并更改模板“DIRS”：[]

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': ['templates'],
    'APP_DIRS': True,
    'OPTIONS': {
        'context_processors': [
            'django.template.context_processors.debug',
            'django.template.context_processors.request',
            'django.contrib.auth.context_processors.auth',
            'django.contrib.messages.context_processors.messages',
        ],
    },
},

]
