Before I share my thoughts here is a question for you. Where do you expect
your product to be printed out?
Here is what I think you should try out.
First, the source code looks correct to me. Your view only get triggered
when you access the routes(url) pointing to this view via the browser and
this doesn't rerun server to print result on your console so you won't see
anything get printed on the console. I presume you could be thinking of
running a django app like you do with ordinary python scripts, your right
but django is a python framework which requires specifics configurations to
get results.
To test your code and see products get printed out try this:
1. Use a template. Modify your view as follows:
def product_task(request):
products = Task.objects.select_related().all()
context = {'products': products}
return render(request, 'product-task.html', context)
Create the template, configure routes in urls.py to point to this view and
access through browser. Remember to add dummy data in your db
2. To print out your products using a for loop, use the django shell using
'*python
manage.py shell*'
e.g.
(.venv)
python manage.py shell
Python 3.12.2 (tags/v3.12.2:6abddd9, Feb 6 2024, 21:26:36) [MSC v.1937 64
bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from stores.models import Task, Product
>>> products = Task.objects.select_related().all()
>>> for p in products:
... print(p.product.product_name)
...
Coffee
Banana Bread
Note:
1. Stores refers to a dummy app I have created to host models.py.
2. Coffee and Banana Bread are just products I have added as dummy data.
Hopes this help or atleast gives a guide somehow
