Django 实现Admin自动填充当前用户的示例代码

model.py

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

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()
 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)
