Django 实现Admin自动填充当前用户的示例代码

import datetimefrom django.contrib.auth.models import Userfrom django.db import modelsclass Entry(models.Model):  title = models.CharField(max_length=250)  slug = models.SlugField()  pub_date = models.DateTimeField(default=datetime.datetime.now)  author = models.ForeignKey(User, related_name='entries')  summary = models.TextField(blank=True)  body = models.TextField()  class Meta:    get_latest_by = 'pub_date'    ordering = ('-pub_date',)    verbose_name_plural = 'entries'  def __unicode__(self):    return self.title  def get_absolute_url(self):    return "/weblog/%s/%s/" % (self.pub_date.strftime("%Y/%b/%d"),                  self.slug)

from django.contrib import adminfrom blog.models import Entryclass EntryAdmin(admin.ModelAdmin):  exclude = ('author',)  list_display = ('title', 'pub_date', 'author')  prepopulated_fields = { 'slug': ['title'] }  def has_change_permission(self, request, obj=None):    has_class_permission = super(EntryAdmin, self).has_change_permission(request, obj)    if not has_class_permission:      return False    if obj is not None and not request.user.is_superuser and request.user.id != obj.author.id:      return False    return True  def queryset(self, request):    if request.user.is_superuser:      return Entry.objects.all()    return Entry.objects.filter(author=request.user)  def save_model(self, request, obj, form, change):    if not change:      obj.author = request.user    obj.save()admin.site.register(Entry, EntryAdmin)
