使用了一个网站的导航模板，设置了一个后台编辑文章数据在前台展示的功能。数据在后台没问题，使用view不能在页面展示了。
views.py
def news(request):
data=3333
news = NewsPost.objects.all()
return render(request,'news.html',{'news':news,'data':data})
models.py
class NewsPost(models.Model):
title = models.CharField(max_length=150)
content = models.TextField()
admin.py
rom page.models import NewsPost
class NewsPostAdmin(admin.ModelAdmin):
list_display = ('id','title', 'content')
list_per_page = 3
admin.site.register(NewsPost,NewsPostAdmin)
