問題描述
如何修復錯誤“str”對像沒有屬性“relative_url” (How to fix error 'str' object has no attribute 'relative_url')
我正在嘗試將一些 wagtail 上下文傳遞到 django 項目的搜索頁面。帖子標題出現，但圖片、描述和其他參數未出現在搜索模板中。如何將這些上下文傳遞給搜索模板？
這是我得到的錯誤
AttributeError at /search/

我做錯了什麼？
參考解法
方法 1:
It seems like the news_page variable in your template is a string, rather than a page object, as that's the only use of the {% routablepageurl %} tag in the code examples you have shared. However, you don't show where news_page is defined, so I may be mistaken.
I have now looked at your models file, and where you define news_page. You have defined news_page in the context of NewsIndexPage. This will be used when displaying a NewsIndexPage, using Wagtail's internal views, but this is not used when rendering the search view.
Here's the response context you are setting in your search/views.py:
# Render template
return render(request, 'search/search.html', {
'search_query': search_query,
'search_results': search_results,
'recent_posts' : posts,
'categories' : categories
})
Can you add news_page to the context there?
