Question

我正在尝试显示名为visit-form.html的文件，但由于某些原因，Django一直在寻找名为visit_form.html的文件（区别在于下划线）。因此，我不断收到TemplateDoesNotExist错误。

我已经尝试清除浏览器缓存，使Pycharm缓存无效（文件＆gt;无效缓存）。我在整个程序中搜索了visit_form.html文件或代码，但没有找到（我在旧的文件路径中找到了一个并且没有更改就删除了文件）。

错误如下，第一个Url位于正确的文件位置，但问题似乎是我无法摆脱的文件名。

Template-loader postmortem
Django tried loading these templates, in this order:

Using engine django:

django.template.loaders.app_directories.Loader: /Users/nrsmoll/PycharmProjects/clincher/clincher/templates/clincher/visit_form.html (Source does not exist)

Urls.py

urlpatterns = [
    # /main/
   path('', views.index, name='index'),
    #/main/<main_id>/
    path('main/', views.MainListView.as_view(), name='main'),
    path('main/<int:pk>', views.MainDetailView.as_view(), name='main-detail'),
    path('visit/add/<int:pk>', views.VisitCreate.as_view(), name='visit-form'),
    url(r'main/add/$', views.MainCreate.as_view(), name='main-add'),
    #/main/main/2/
    url(r'^(?P<pk>[0-9]+)/$', views.MainUpdate.as_view(), name='main-update'),
    #/main/main/2/
    url(r'^(?P<pk>[0-9]+)/delete/$', views.MainDelete.as_view(), name='main-delete'),
]

Views.py

class VisitCreate(CreateView):
    model = Visit
    fields = ['fk_visit_main', 'visit_progress_notes']

    def get_success_url(self):
        return reverse('clincher:main-detail', args={'pk': self.object.id})

Settings.py

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [os.path.join(BASE_DIR, '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',
        ],
    },
},
]

visit-form（正确文件）的原始链接是：

Html模板

<td><a href="{% url 'clincher:visit-form' main.id %}"  role="button" class="btn btn-primary btn-xs">New Consult</a></td>

Answer 1

模板名称与网址格式中的名称无关。

您可以在视图中设置模板名称：

class VisitCreate(CreateView):
    model = Visit
    fields = ['fk_visit_main', 'visit_progress_notes']

    template_name = 'clincher/visit-form.html'

但是，由于默认情况下the create view uses <app_name>/<model_name>_form.html（全部小写），因此最好将模板重命名为使用下划线而不是连字符。

Django：Url路由到错误的文件，但位置正确：TemplateDoesNotExist错误
