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

问题

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

回答1:

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

回答2:

Make sure your site_indexes.py is in an app that you have registered in the INSTALLED_APPS in settings.py
