Introdu\u00e7\u00e3o<\/h2>\n\n\n\n

O Celery \u00e9 uma poderosa ferramenta para execu\u00e7\u00e3o de tarefas ass\u00edncronas no Django. Ele permite processar tarefas em segundo plano, melhorando o desempenho e a escalabilidade das aplica\u00e7\u00f5es web. Neste artigo, vamos mostrar como configurar e utilizar o Celery no Django de forma eficiente.<\/p>\n\n\n\n

O Que \u00e9 o Celery?<\/h2>\n\n\n\n

Celery \u00e9 um sistema de fila de tarefas distribu\u00eddas que permite a execu\u00e7\u00e3o ass\u00edncrona de fun\u00e7\u00f5es Python. Ele \u00e9 amplamente usado em aplica\u00e7\u00f5es Django para executar tarefas demoradas, como envio de e-mails, processamento de arquivos e integra\u00e7\u00e3o com APIs externas.<\/p>\n\n\n\n

Instalando o Celery no Django<\/h2>\n\n\n\n

Para come\u00e7ar, precisamos instalar o Celery e um backend para armazenar as filas de tarefas, como o Redis:<\/p>\n\n\n\n

<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
pip<\/span> <\/span>install<\/span> <\/span>celery<\/span> <\/span>redis<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
Em seguida, configure o Celery no seu projeto Django:<\/p>\n\n\n\n
Configurando o Celery<\/h3>\n\n\n\n
Crie um arquivo celery.py<\/code> dentro do seu app principal e adicione:<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
import<\/span> <\/span>os<\/span><\/span>\nfrom<\/span> <\/span>celery<\/span> <\/span>import<\/span> <\/span>Celery<\/span><\/span>\n<\/span>\nos<\/span>.<\/span>environ<\/span>.<\/span>setdefault<\/span>(<\/span>'<\/span>DJANGO_SETTINGS_MODULE<\/span>'<\/span>,<\/span> <\/span>'<\/span>seu_projeto.settings<\/span>'<\/span>)<\/span><\/span>\n<\/span>\napp<\/span> = <\/span>Celery<\/span>(<\/span>'<\/span>seu_projeto<\/span>'<\/span>)<\/span><\/span>\napp<\/span>.<\/span>config_from_object<\/span>(<\/span>'<\/span>django.conf:settings<\/span>'<\/span>)<\/span><\/span>\napp<\/span>.<\/span>autodiscover_tasks<\/span>()<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
No settings.py<\/code>, adicione as configura\u00e7\u00f5es do Celery:<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
BROKER_URL<\/span> <\/span>=<\/span> <\/span>'<\/span>redis:\/\/localhost:6379\/0<\/span>'<\/span><\/span>\nCELERY_BROKER_URL<\/span> <\/span>=<\/span> <\/span>'<\/span>redis:\/\/localhost:6379\/0<\/span>'<\/span>  <\/span><\/span>\nCELERY_ACCEPT_CONTENT<\/span> <\/span>=<\/span> [<\/span>'<\/span>json<\/span>'<\/span>]<\/span><\/span>\nCELERY_TASK_SERIALIZER<\/span> <\/span>=<\/span> <\/span>'<\/span>json<\/span>'<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
Criando Tarefas no Celery<\/h2>\n\n\n\n
Para criar uma tarefa ass\u00edncrona, crie um arquivo tasks.py<\/code> dentro do seu app e defina:<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
from<\/span> <\/span>celery<\/span> <\/span>import<\/span> <\/span>shared_task<\/span><\/span>\n<\/span>\n@<\/span>shared_task<\/span><\/span>\ndef<\/span> <\/span>adicionar<\/span>(<\/span>x<\/span>,<\/span> <\/span>y<\/span>):<\/span><\/span>\n    <\/span>return<\/span> <\/span>x<\/span> + <\/span>y<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
Agora voc\u00ea pode chamar essa tarefa de forma ass\u00edncrona:<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
adicionar<\/span>.<\/span>delay<\/span>(<\/span>4<\/span>,<\/span> <\/span>6<\/span>)<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
Executando o Celery<\/h2>\n\n\n\n
Para iniciar o Celery, execute o seguinte comando:<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
celery<\/span> <\/span>-<\/span>A<\/span> <\/span>seu_projeto<\/span> <\/span>worker<\/span> <\/span>--<\/span>loglevel<\/span>=<\/span>info<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
Isso iniciar\u00e1 um worker que processar\u00e1 as tarefas em segundo plano.<\/p>\n\n\n\n
Monitorando Tarefas com Flower<\/h2>\n\n\n\n
Para monitorar as tarefas do Celery, instale o Flower:<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
pip<\/span> <\/span>install<\/span> <\/span>flower<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
Execute o Flower para visualizar o status das tarefas:<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
celery<\/span> <\/span>-<\/span>A<\/span> <\/span>seu_projeto<\/span> <\/span>flower<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
Isso abrir\u00e1 uma interface web onde voc\u00ea pode acompanhar suas tarefas.<\/p>\n\n\n\n
Conclus\u00e3o<\/h2>\n\n\n\n
O Celery \u00e9 uma ferramenta essencial para quem deseja melhorar o desempenho de aplica\u00e7\u00f5es Django. Com ele, \u00e9 poss\u00edvel executar tarefas demoradas em segundo plano, garantindo maior efici\u00eancia e escalabilidade.<\/p>\n\n\n\n
Se voc\u00ea deseja otimizar sua aplica\u00e7\u00e3o Django, implementar o Celery \u00e9 um excelente passo!<\/p>\n\n\n\n
