django 发布者 默认值

models.py:

from django.contrib.auth.models import User

class Essay(models.Model):
    title = models.CharField(max_length=666)
    body = models.TextField()
    publisher = models.ForeignKey(User, null=True, blank=True)

admin.py:

from myapplication.essay.models import Essay
from django.contrib import admin

class EssayAdmin(admin.ModelAdmin):
    list_display = ('title', 'author')
    fieldsets = [
        (None, { 'fields': [('title','body')] } ),
    ]

    def save_model(self, request, obj, form, change):
        if getattr(obj, 'publisher', None) is None:
            obj.publisher = request.user
        obj.save()

这样设置以后默认就可以自动填充Publisher字段

    list_display = ('title','orders','format_date','publisher','thumbnail')
    exclude = ('publisher',)
