实现Django Admin自动填充当前用户的功能

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)
