使用M2M中介模型的Django : list_display和视图

# models.py
from django.db import models

class Tag(models.Model):
    name = models.CharField(max_length=50)

    def __str__(self):
        return self.name

class Article(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
    tags = models.ManyToManyField(Tag, through='ArticleTag')

    def __str__(self):
        return self.title

class ArticleTag(models.Model):
    article = models.ForeignKey(Article, on_delete=models.CASCADE)
    tag = models.ForeignKey(Tag, on_delete=models.CASCADE)

# admin.py
from django.contrib import admin
from .models import Article, Tag, ArticleTag

class ArticleTagInline(admin.TabularInline):
    model = ArticleTag

class ArticleAdmin(admin.ModelAdmin):
    list_display = ('title', 'get_tags')

    def get_tags(self, obj):
        return ", ".join([tag.name for tag in obj.tags.all()])

    get_tags.short_description = 'Tags'

    inlines = [
        ArticleTagInline,
    ]

admin.site.register(Article, ArticleAdmin)
admin.site.register(Tag)

# views.py
from django.shortcuts import render
from .models import Article

def article_list(request):
    articles = Article.objects.all()
    return render(request, 'articles/article_list.html', {'articles': articles})
