## Django Admin自动填充当前用户的示例代码

### model.py

```python
import datetime
 
from django.contrib.auth.models import User
from django.db import models
 
 
class 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)
```

### admin.py

```python
from django.contrib import admin
 
from blog.models import Entry
 
 
class 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()
