如何修复错误 'str' object 没有属性 'relative_url'
How to fix error 'str' object has no attribute 'relative_url'
我正在尝试将一些 wagtail 上下文传递到 django 项目的搜索页面。 post 标题出现，但图像、描述和其他参数未出现在搜索模板中。如何将这些上下文传递给搜索模板？
这是我得到的错误

我做错了什么？
您模板中的 news_page 变量似乎是一个字符串，而不是页面对象，因为这是您共享的代码示例中唯一使用 {% routablepageurl %} 标记的地方。 但是，您没有显示 news_page 的定义位置，所以我可能弄错了。
我现在已经查看了您的模型文件，以及您定义 news_page 的位置。您已在 NewsIndexPage 的上下文中定义 news_page。这将在使用 Wagtail 的内部视图显示 NewsIndexPage 时使用，但在呈现搜索视图时不会使用。
这是您在 search/views.py 中设置的响应上下文：
# Render template
return render(request, 'search/search.html', {
'search_query': search_query,
'search_results': search_results,
'recent_posts' : posts,
'categories' : categories
})
你能在上下文中添加 news_page 吗？
