      1. make connection with django_elasticsearch_dsl

      2. make default data by using search_cofig.json

      3. bulk default data on elastic_search

JWT

  • used_library

    • djangorestframework-jwt
  • JWT_Settings.py

    • set JWTโ€™s default_settings

  • JWT on frontEND

    • restore tokens by using redux
    • if we need some user data, we donโ€™t need to make connection with backend by opening JWT payload, we can get user data
  • JWT on backEND

    • after we identify user by check login data, give authorization by using JWT
    • by using refresh_token, we enhanced our security level
