Django Elasticsearch ( Em desenvolvimento )

Projeto testando Elasticsearch com Django

Requisitos

• Docker
• Docker-compose
• Python 3.7
• Elasticsearch 6.8

Começando

Migrando de arquivos JSON na pasta fixtures e rodando o projeto:

Via Docker

1. docker-compose build
2. docker-compose run --service-ports --rm django python manage.py bootstrap
3. docker-compose run --service-ports --rm django python manage.py setup_courses
4. docker-compose up

Via Docker/ Servidor Local (Opção de DEBUG)

1. docker pull docker.elastic.co/elasticsearch/elasticsearch:6.8.9
2. docker run --name django_elastic -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:6.8.9
3. docker pull postgres:10
4. docker run --name django_postgres -e POSTGRES_PASSWORD=postgres -e POSTGRES_DB=django_elastic -d -p 5432:5432 postgres:10
5. python manage.py bootstrap
6. python manage.py setup_courses
7. python manage.py runserver

Rodando o elastic e o postgres é possivel debugar e implementar novos modelos e indices.

Teste o Elasticsearch com o shell:

1. docker-compose up
2. docker-compose exec django python manage.py shell

Exemplos de uso

## Para app Cars

cars = CarDocument.search().query('match', color='black')
for car in cars:
    print(car.color)

## Score de indice em Cars
cars = CarDocument.search().extra(size=0)
cars.aggs.bucket('points_count', 'terms', field='points')
result = cars.execute()
for point in result.aggregations.points_count:
    print(point)

## Para App Courses

courses = CourseDocument.search().query('match', title='Financial')
for course in courses:
    print(course.title)
