haystack.exceptions.SearchBackendError：在任何search_indexes中找不到任何字段。尝试搜索之前请更正 [英] haystack.exceptions.SearchBackendError: No fields were found in any search_indexes. Please correct this before attempting to search

问题描述

我一直在收到这个错误，尽管一切似乎都被配置好了。我收到错误：

  haystack.exceptions.SearchBackendError：在任何search_indexes中找不到字段。尝试搜索之前请更正。 
  

...当我尝试执行 ./ manage.py rebuild_index

配置：

  HAYSTACK_SITECONF ='myproject'
 HAYSTACK_SEARCH_ENGINE ='whoosh'
 HAYSTACK_WHOOSH_PATH = cwd +'/ whoosh / mysite_index'
  

在我的项目的根文件夹中成功创建了 whoosh / mysite_index 目录。

* search_sites.py *

  import haystack 
 haystack.autodiscover（）
  

* search_indexes.py *

$ b $来自haystack.indexes import的$
从haystack导入站点
来自myproject.models import的


class ResearchersIndex（SearchIndex） ：
text = CharField（document = True，use_template = True）
name = CharFIeld（model_attr ='name'）

class SubjectIndex（SearchIndex）：
short_name = CharField（model_attr ='short_name'）
name = CharField（model_attr ='name'）
text = CharField（document = True，use_template = True）

class ResearchIndex
text = CharField（document = True，use_template = True）
abstract = TextField（model_attr ='abstract'）
methods = TextField（model_attr ='methods'）
year = IntegerField（model_attr ='year'）
name = CharField（model_attr ='name'）


class Graph（SearchIndex）：
text = CharField（document = True，use_template = True）
explain = TextField（model_attr ='explain'）
type = CharField（model_attr ='type '）
name = CharField（model_attr ='name'）

site.register（研究人员，研究员指数）
site.register（Subject，SubjectIndex）
网站。注册（Research，ResearchIndex）
site.register（Graph，GraphIndex）


谢谢

解决方案

问题出在你的 HAYSTACK_SITECONF 中。它必须是您的 search_sites 文件的路径。修正这个，它应该可以工作。

I am trying to implement Haystack with whoosh.

I keep getting this error although everything seems to be configured fine. I get the error:

haystack.exceptions.SearchBackendError: No fields were found in any search_indexes. Please correct this before attempting to search.

...when I try to do ./manage.py rebuild_index

configuration:

HAYSTACK_SITECONF = 'myproject'
HAYSTACK_SEARCH_ENGINE = 'whoosh'
HAYSTACK_WHOOSH_PATH = cwd + '/whoosh/mysite_index'

There are successfully created whoosh/mysite_index directories in the root folder of my project.

*search_sites.py*

import haystack
haystack.autodiscover()

*search_indexes.py*

from haystack.indexes import *
from haystack import site
from myproject.models import *

class ResearchersIndex(SearchIndex):
    text = CharField(document=True, use_template=True)
    name = CharFIeld(model_attr='name')

class SubjectIndex(SearchIndex):
    short_name = CharField(model_attr='short_name')
    name = CharField(model_attr='name')
    text = CharField(document=True, use_template=True)

class ResearchIndex(SearchIndex):
    text = CharField(document=True, use_template=True)
    abstract = TextField(model_attr='abstract')
    methodology = TextField(model_attr='methodology')
    year = IntegerField(model_attr='year')
    name = CharField(model_attr='name')


class Graph(SearchIndex):
    text = CharField(document=True, use_template=True)
    explanation = TextField(model_attr='explanation')
    type = CharField(model_attr='type')
    name = CharField(model_attr='name')

site.register(Researchers, ResearchersIndex)
site.register(Subject, SubjectIndex)
site.register(Research, ResearchIndex)
site.register(Graph, GraphIndex)

Thanks

解决方案

the problem is in your HAYSTACK_SITECONF. It must be the path to your search_sites file. Fix this and it should work.
