问题：

运行 python manage.py build_solr_schema 出现如下错误:

TypeError : context must be a dict rather than Context

解决方法：

1.检查haystack是否为最新版(推荐版本（我用的版本）)：

Operating system version: Ubuntu 16.04.2 LTS (GNU/Linux 4.8.0-54-generic x86_64)

Search engine version: solr 4.10.4

Python version: 3.5

Django version: 1.11.4

Haystack version: 2.6.1

2.打开 site-packages\haystack\management\commands\build_solr_schema.py文件

打开build_solr_schema.py文件

def build_context(self, using):
backend = connections[using].get_backend()

if not isinstance(backend, SolrSearchBackend):
raise ImproperlyConfigured("'%s' isn't configured as a SolrEngine)." % backend.connection_alias)

content_field_name, fields = backend.build_schema(
connections[using].get_unified_index().all_searchfields()
)
return Context({
'content_field_name': content_field_name,
'fields': fields,
'default_operator': constants.DEFAULT_OPERATOR,
'ID': constants.ID,
'DJANGO_CT': constants.DJANGO_CT,
'DJANGO_ID': constants.DJANGO_ID,
})

修改为：

def build_context(self, using):
backend = connections[using].get_backend()

if not isinstance(backend, SolrSearchBackend):
raise ImproperlyConfigured("'%s' isn't configured as a SolrEngine)." % backend.connection_alias)

content_field_name, fields = backend.build_schema(
connections[using].get_unified_index().all_searchfields()
)
Context = {
'content_field_name': content_field_name,
'fields': fields,
'default_operator': constants.DEFAULT_OPERATOR,
'ID': constants.ID,
'DJANGO_CT': constants.DJANGO_CT,
'DJANGO_ID': constants.DJANGO_ID,
}
return Context

3.重新运行 python manage.py build_solr_schema

显示为：



运行成功，输出schema.xml的代码内容
