Question

在我的一个项目中，正在

上搜索模板

<project_root>/<app>/templates/

正在另一个搜索中

<project_root>/<app>/templates/<app>/

这究竟取决于什么

两个项目的settings.py在settings.py中都具有以下完全相同的配置

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        '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',
            ],
        },
    }, ]

这是错误

处理视图为

class PrinterCreate(CreateView):
    model = Printer
    form_class = PrinterCreateForm
    template_name = 'printer_add.html'
    success_url = reverse_lazy('printer_list')

Answer 1

您要在/opt/app/w_apps/sts/templates/sts/printer_add.html中使用模板

回溯显示它正在/opt/app/w_apps/sts/templates目录中查找。这是因为您的'APP_DIRS': True设置中有TEMPLATES。

如果将模板位置分为两个，则会得到：

/opt/app/w_apps/sts/templates/sts/printer_add.html = /opt/app/w_apps/sts/templates/ + sts/printer_add.html

因此，您应该在视图中使用sts/printer_add.html作为模板名称。

class PrinterCreate(CreateView):
    ...
    template_name = 'sts/printer_add.html'

Django在templates / app目录中找不到模板
