我无法在 html 文件中传递动态数据

Question

我想将我的数据库信息呈现为 HTML 页面。我使用了从数据库传递动态数据的方式。但是，它不起作用。结果我看到一个空白页面。

models.py

class Business(models.Model):
    business_name = models.CharField(max_length=50)
    business_services = models.CharField(max_length =50)
    business_location = models.CharField(max_length=200)
    business_description = models.TextField()

    def __str__(self):
        return self.business_name

views.py

def get_data(request):
    business = Business.objects.all()
    b = {'business': business}
    return render(request, "test.html", b)

urls.py

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', get_data),

    ]

test.html

{{ business.business_name }}
{{ business.services }}

Answer 1

business 是类Business 的实例。因此，在 test.html 中，执行以下操作：

{% for b in business %}
    {{ b.business_name }}
    {{ b.services }}
{% endfor %}
