无法使用自定义related_widget_wrapper.html

Question

如果我使用自定义related_widget_wrapper.html，我会收到TemplateDoesNotExist错误。我做的是，我在templates / dashboard目录中创建了一个名为widgets的文件夹，并添加了一个related_widget_wrapper.html文件。这样我得到了上面提到的错误，我发现了什么奇怪的事情

django.template.loaders.filesystem.Loader: /Users/.virtualenvs/furniture/lib/python3.6/site-packages/django/forms/templates/dashboard/widgets/related_widget_wrapper.html (Source does not exist)

它不是在我的应用程序内搜索。我的意思是它应该在我的项目模板中搜索。我错过了什么或者我做错了什么？

模板设置

location = lambda x: os.path.join(BASE_DIR, x)

FURNITURE_MAIN_TEMPLATE_DIR = os.path.join(
    os.path.dirname(os.path.abspath(__file__)), 'templates')
'DIRS': [location('templates'), furniture.FURNITURE_MAIN_TEMPLATE_DIR],

模板树是

项目

应用

• 目录 篮 仪表板

模板

• 目录 篮 仪表板 base.html文件

Answer 1

从dashboard应用程序目录开始

然后你需要创建templates并将related_widget_wrapper.html文件放在那里

所以你的RelatedFieldWidgetWrapper类的财产将如下所示

class RelatedFieldWidgetWrapper(Widget):
    template_name = 'related_widget_wrapper.html'
