error rebuilding the index using django-elasticsearch-dsl - django

Question

I am trying to connect to a existing index in my local elastic search engine.
I am using django-elasticsearch-dsl package. I followed this tutorial to do that. https://github.com/sabricot/django-elasticsearch-dsl
please note that,I already developed my django app[website] with mysql database. I have some unstructured text data indexed in elastic-search. I want to develop this 'advanced search' HTML page for users querying data frpm elasticsearch.
I followed almost everything upto
python manage.py search_index --rebuild but once I excute it it asked Are you sure you want to delete the 'website_data_discovery' indexes? [n/Y]: when I say n it will be aborted.
when I say Y it gives a lengthy error saying django.db.utils.ProgrammingError: Table 'crdc.website_data_discovery' doesn't exist
This is my file structure.
crdc
website
->__pycache__
-> media
->migrations
->static
->templates
->__init__.py
->admin.py
->apps.py
->documnets.py
->forms.py
->models.py
->tests.py
->urls.py
->views.py
manage.py
This is my settings.py/crdc.

This is documents.py/website
from django_elasticsearch_dsl import DocType, Index
from .models import Data_Discovery
data_discovery = Index('website_data_discovery')
data_discovery.settings( number_of_shards = 5, number_of_replicas = 1,)
#data_discovery.doc_type
class Data_DiscoveryDocument(DocType):
class Meta:
model = Data_Discovery
fields = ['extracted_text', 'source_type']
this is models.py/website
from django.db import models
class WebsiteRepository(models.Model):
##### mysql model
class Documents(models.Model):
#### mysql model
class Data_Deposite(models.Model):
#### mysql model
class Data_Discovery(models.Model):
## Elasticsearch model
Any help would be greatly appreciated. Thanks

Answer 1

I know this is late. But, I thought I should answer my own question, so that anyone face the same problem, can figure it out.
I created another App for Elastic search component.Yes, I created another App under the same project. And I followed this tutorial https://pypi.org/project/django-elasticsearch-dsl/
Then I called Elasticsearch view functions at views.py from the website App. It works perfectly now.
I am not a expert in Django or Elastic Search. So, I can not explain why it is not working as the previous attempt. I hope this helps to anyone who comes to this kind of situation.
