使用Django中的内联摘要生成列表/报告

class MyModel(models.Model):
    name = models.CharField(max_length=100)
    description = models.TextField()

    def summary(self):
        return f"{self.name}: {self.description[:50]}"

from django.views.generic import ListView
from .models import MyModel

class MyModelListView(ListView):
    model = MyModel
    context_object_name = 'my_model_list'

    def get_queryset(self):
        return MyModel.objects.all().order_by('name')

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['summary_list'] = [m.summary() for m in context['my_model_list']]
        return context

{% for summary in summary_list %}
    <p>{{ summary }}</p>
{% endfor %}
