Django: Saved data is not outputting to html .(I am real beginner.)

Thank you for reading.

Even though data is stored in the Product, it is not output to the store.html screen. What might be the problem? I checked Product is saved with admin page.

I'm so new I have no idea what I'm doing wrong. Thank you very much.

views.py

def store(request):
    global products, context
    data = cartData(request)

    cartItems = data['cartItems']
    products = Product.objects.all()

    context = {'products': products, 'cartItems': cartItems}
    return render(request, 'maps/store.html', context)

models.py

class Product(models.Model):
    poiid = models.DecimalField(max_digits=7, decimal_places=2)
    name = models.CharField(max_length=200, null=True)
    price = models.CharField(max_length=7, null=True)
    address = models.CharField(max_length=7, null=True)
    digital = models.BooleanField(default=False, null=True, blank=True)

    def save(self, *args, **kwargs):
        super().save(*args, **kwargs)  # Call the "real" save() method.

    def __str__(self):
        return self.name

        # url = ''
        # return url

store.html

{% extends 'maps/main.html' %}
{% load static %}
{% block content %}

<div class="row">
    <div class="col-md">
        <div class="card card-body">
            <table class="table table-sm">
                <tr>
                    <th>poiid</th>
                    <th>name</th>
                    <th>category</th>
                    <th>address</th>
                    <th>save</th>
                </tr>

                {% for product in products %}

                <tr>
                    <td>{{product.poiid}}</td>
                    <td>{{product.name}}</td>
                    <td>{{product.price}}</td>
                    <td>{{product.address}}</td>
                    <td><button data-product={{product.id}} data-action='add' class="btn btn-outline-secondary add-btn update-cart">save</button></td>
                </tr>
                {% endfor %}

            </table>
        </div>
    </div>
</div>
{% endblock content %}
