I'm working on a project using django-python. This has "oaisearch" installed to retrieve the metadata from different websites and "django_elasticsearch_dsl" to index them. It was verified that "oaisearch" runs without problems.
The problem occurs when "python3 manage.py search_index --create -f" is run to start indexing.
The file "documents.py" that has the configuration of what you want to index is the following.
from elasticsearch_dsl import analyzer
from django_elasticsearch_dsl import DocType, Index
from oaisearch.models import Digital_Resources
digital_resources = Index('digital_resources')
digital_resources.settings(
number_of_shards=1,
number_of_replicas=0
)
html_strip = analyzer(
'html_strip',
tokenizer="standard",
filter=["standard", "lowercase", "stop", "snowball"],
char_filter=["html_strip"]
)
@digital_resources.doc_type
class Resources(DocType):
class Meta:
model = Digital_Resources
fields = [
#'oai_server',
'creator',
'title',
'subject',
'description',
'identifier',
]
The console failure message after executing the aforementioned command is as follows
Creating index 'digital_resources'
PUT http://localhost:9200/digital_resources [status:400 request:0.014s]

What version of elasticsearch are you running? It looks like you are running elasticsearch 7.x which is not yet supported by your version of django_elasticsearch_dsl. Try looking for a newer version or using elasticsearch 6.x.
