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

Question

我正在尝试显示一个名为 visit-form.html 的文件，但出于某种原因 Django 一直在寻找一个名为 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 > 使缓存无效）。我在整个程序中搜索了 visit_form.html 文件或代码，但可以找到 none（我在旧文件路径中找到了一个，并删除了该文件而没有更改）。

错误如下，第一个Url在正确的文件位置，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:

    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 = [

    'APP_DIRS': True,

            'django.contrib.messages.context_processors.messages',
        ],
    },
},
]

原来的link到visit-form（正确的文件）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

模板名称与您 URL 模式中的名称无关。

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），最好重命名您的模板以使用下划线而不是连字符。
