### Create the `Settings` object { #create-the-settings-object }

Import `BaseSettings` from Pydantic and create a sub-class, very much like with a Pydantic model.

The same way as with Pydantic models, you declare class attributes with type annotations, and possibly default values.

For example, with an ID of `42`, this would render:

```html
<a href="/items/42">
```

## Templates and static files { #templates-and-static-files }

You can also use `url_for()` inside of the template, and use it, for example, with the `StaticFiles` you mounted with the `name="static"`.

```jinja hl_lines="4"

				{Name: "temporary/0/"},

		//    * Listing with marker > last object should return empty
		//    * Listing an object with a trailing slash and '/' delimiter

			Objects:     []ObjectInfo{},
		},
		// ListObjectsResult-35 list with custom uncommon delimiter

			Objects: []ObjectInfo{

    }
