尝试使用Django 2.1.4创建简单的应用程序。
项目名称为“ inventory_management”,项目内部的应用程序称为“ gInventory”。
这是我的文件管理的树状视图:

每当我运行本地服务器并尝试拉出网页时,我都希望index.html出现。相反,我收到一条错误消息,指出“ / index.html处的TemplateDoesNotExist”-该模板不存在,但是我认为该路径有效。
以下是Django尝试加载的错误:

感谢任何可以提供帮助的人!

在您的Settings.py
中,您需要用以下代码替换DIRS
中的TEMPLATES
。
'DIRS': [os.path.join(BASE_DIR, 'templates')],
这定义您在项目的基本目录中拥有template
文件夹。
您应该遵循的惯例:
在templates
文件夹中创建一个以您的应用程序命名的文件夹,并将html放入其中。
+---templates/
| ginventory/
| base.html
| index.html
在您的view
函数中,您将html地址指定为:
def index(request):
return render(request, 'ginventory/index.html')

将模板文件夹移动到public class ListItem {
public ListItem(int ImageSrc, string ItemName)
{
this.ImageSrc = ImageSrc;
this.ItemName = ItemName;
}
public int ImageSrc { get; set; }
public string ItemName { get; set; }
}
public class MyAdapter : BaseAdapter
{
List<ListItem> listItems;
Context context;
public MyAdapter(List<ListItem> listItems, Context context)
{
this.listItems = listItems;
this.context = context;
}
public override int Count => listItems.Count;
public override Java.Lang.Object GetItem(int position)
{
throw new NotImplementedException();
}
public override long GetItemId(int position)
{
return position;
}
public override View GetView(int position, View convertView, ViewGroup parent)
{
convertView = LayoutInflater.From(context).Inflate(Resource.Layout.ListItem, parent, false);
TextView textView = convertView.FindViewById<TextView>(Resource.Id.Ls_textview);
ImageView imageView = convertView.FindViewById<ImageView>(Resource.Id.Ls_ImageView);
//int id=Resource.Drawable.Capture;
textView.Text = listItems[position].ItemName;
imageView.SetImageResource(listItems[position].ImageSrc);
return convertView;
}
}

如果要按照官方文档的建议进行操作,请按照以下步骤操作:
您项目的TEMPLATES设置描述了Django如何加载和 渲染模板。默认设置文件配置了 将APP_DIRS选项设置为True的DjangoTemplates后端。通过 约定DjangoTemplates在以下位置查找“ templates”子目录 每个INSTALLED_APPS。
因此,请检查您的应用名称是否在INSTALLED_APPS
列表中。然后在settings.py
内部检查并寻找TEMPLATES
,然后检查是否'APP_DIRS': True
。
您的模板文件应该在以下路径中:myproject/myapp/templates/myapp/mypage.html
这是django在每个应用程序中查找模板的方式。
最后,您的views函数应以如下形式结束:
def索引(请求):
....
返回渲染(请求,“ portal / index.html”,上下文)
