SearchFieldError - 无法使用字段 "body" 进行搜索。请将 index.SearchField('body') 添加到 Page.search_fields

Question

我有一个 elasticsearch 后端 (7.14.0) 和 wagtail (2.14.1)，我想在我页面的正文字段中包含一个全文搜索。在前端搜索内容时，我得到

我的views.py:

from django.core.paginator import EmptyPage, PageNotAnInteger, Paginator
from django.template.response import TemplateResponse

from wagtail.core.models import Page
from wagtail.search.models import Query




def search(request):
    search_query = request.GET.get('query', None)
    page = request.GET.get('page', 1)

    # Search
    if search_query:
        #search_results = Page.objects.live().search(search_query)
        # exclude some search results
        search_results = Page.objects.live()\
        .exclude(title='Sie sind nun ausgeloggt.')\
        .exclude(title='Sie sind nun eingeloggt.')\
        .exclude(title='Passwort erfolgreich geändert.')\
        .search(search_query, fields=["title", "body"])

        query = Query.get(search_query)

        # Record hit
        query.add_hit()
    else:
        search_results = Page.objects.none()

    # Pagination
    paginator = Paginator(search_results, 10)
    try:
        search_results = paginator.page(page)
    except PageNotAnInteger:
        search_results = paginator.page(1)
    except EmptyPage:
        search_results = paginator.page(paginator.num_pages)

    return TemplateResponse(request, 'search/search.html', {
        'search_query': search_query,
        'search_results': search_results,
    })

我的models.py:

from django.db import models

from wagtail.core.models import Page
from wagtail.core.fields import RichTextField
from wagtail.admin.edit_handlers import FieldPanel

from wagtail.search import index


class HomePage(Page):
    body = RichTextField(blank=True)

    content_panels = Page.content_panels + [
        FieldPanel('body', classname="full"),
    ]

    # Search index configuration

    search_fields = Page.search_fields + [ # Inherit search_fields from Page
        index.SearchField('body'),
    ]

所以我已经 将 index.SearchField('body') 添加到 Page.search_fields，但找不到任何 type-o。知道我做错了什么吗？

在搜索查询上设置 fields=["title", "body"] 在这里不起作用，因为您的搜索查询是运行基本 Page 模型（这是正确的做法，如果您希望搜索涵盖所有页面类型）- 这里的 body 字段特定于 HomePage 模型，因此一般无法识别。

通常，字段集会因一种页面类型而异，如果您要在一种特定页面类型中查找特定内容，则只能在搜索中包含 fields=[...]：

EventPage.objects.search('london', fields=['location'])

对于通用搜索，您应该在搜索时省略 fields=[...] 参数 - 然后它将搜索所有页面类型中已命名为 SearchFields 的所有字段。您应该将 index.SearchField('body') 行保留在主页定义中，并确保您在添加它后重新运行 ./manage.py update_index。
