我有 3 个与列出具有功能的产品相关的表，我想在模板 html 文件中使用 for 循环列出 FeatureItem 值。我试图编写一个视图类，但我无法成功。任何建议views.py和template.html文件的哪种方法是最好的解决方案？谢谢。

class Item(models.Model):
    title = models.CharField(max_length=100)
    price = models.FloatField()
    slug = models.SlugField()
    category = models.ForeignKey(Category,  on_delete=models.CASCADE)
    feature = models.ForeignKey(Feature, on_delete=models.CASCADE)

class FeatureItem(models.Model):
    feature_title = models.CharField(max_length=100)
    feature_description = models.CharField(max_length=100)
    feature_id = models.ForeignKey(Feature, on_delete=models.CASCADE)

class Feature(models.Model):
    title = models.CharField(max_length=100)
    description = models.TextField()

urls.py:

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

views.py：

def some_view_function(request):
 
    feature_items = models.FeatureItem.objects.all()
 
    context = {
        'feature_items' : feature_items,
         ... 
    }

    return render(request, 'some_template.html', context=context)

some_template.html：

...
<div>
{% for feature_item in feature_items %}
  Title: {{ feature_item.feature_title }}
{% endfor %}
...
