# CELERY

### Download  & install reddis

{% embed url="<https://github.com/tporadowski/redis/releases>" %}

### go to &#x20;

### Install django,celery redis

```bash
pip install django celery redis
```

**Create a Django Project**:

Run the following command to create a new Django project:

```bash
django-admin startproject project_name
```

**Navigate to the Project Directory**:

Move into the project directory:

```bash
cd project_name
```

**Create a Django App**:

Create a new app within the project:

```bash
python manage.py startapp app_name
```

### Link App With Project

**Create a URL Mapping**&#x20;

<br>

**app\_name/urls.py**

```python
# app_name/urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('', views.index, name='index'),
]

```

**app\_name/views.py**

```python
# app_name/views.py

from django.http import HttpResponse

def my_view(request):
    return HttpResponse("Hello from my view!")

```

**project settings.py**

```
INSTALLED_APPS = [
    'app_name'
]
```

**project urls.py**

```python
# project_name/urls.py

from django.contrib import admin
from django.urls import path, include  # Import the include function

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('app_name.urls')),  # Include the app's URLs
]
```

**Start the Development Server To Check**

```bash
python manage.py runserver
```

**প্রজেক্ট ডিরেক্টরির যেখানে settings.py ফাইল আছে সেখানে celery.py নামে একটি ফাইল তৈরী করি।**

```python
from __future__ import absolute_import, unicode_literals
import os
from celery import Celery

# Set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project_name.settings')

app = Celery('project_name',broker='redis://localhost:6379/0')  # Use the same name as your Django project

# This reads the configuration from the Django settings file.
app.config_from_object('django.conf:settings', namespace='CELERY')

# Load task modules from all registered Django app configs.
app.autodiscover_tasks()

@app.task(bind=True)
def debug_task(self):
    print('Request: {0!r}'.format(self.request))

```

**app ফোল্ডারে tasks.py নামে একটি ফাইল তৈরী করি**&#x20;

```python
# app_name/tasks.py

from celery import shared_task

@shared_task
def my_task(parameter):
    # Your task logic here
    return "Task completed"
```

**প্রজেক্ট ফোল্ডারে cmd ওপেন করে নিচের কমান্ড রান করি**

```bash
celery -A project_name worker -l info
```

**app ফোল্ডারে views.py নামে ফাইলটি নিচের মত করি**

```python
from django.shortcuts import render
from django.http import HttpResponse  # Import HttpResponse

from .tasks import my_task

def index(request):
    # ...
    result = my_task.delay(5)

    return HttpResponse("Task triggered successfully")  # Return an HttpResponse
```

**এবার চেক করি celery টাস্কটি কাজ করছে কিনা।**
