在Django'中操作数据；保存上的管理面板

好的，下面是瘦子：

# models.py
class Article( models.Model ):
    title           = models.CharField( max_length = 255 )
    author          = models.ForeignKey( User )
    published_at    = models.DateTimeField( auto_now_add = True )
    body            = models.TextField( )

    def __unicode__( self ):
        return self.title

# admin.py
from hpccoe.news.models import Article
from django.contrib import admin
from django import forms
from django.forms import widgets

class ArticleAdminForm( forms.ModelForm ):    
    title   = forms.CharField( max_length = 255, required = True )
    body    = forms.CharField( required = True, widget = widgets.Textarea )

class ArticleAdmin( admin.ModelAdmin ):
    fields  = [ 'title', 'body' ]
    form    = ArticleAdminForm

admin.site.register( Article, ArticleAdmin )

如您所见，我省略了Admin表单中的author字段。我想在保存之前自动填充它。我如何做到这一点？我在谷歌上呆了一个小时都没用

提前感谢。

来自：

class ArticleAdmin( admin.ModelAdmin ):
    fields  = [ 'title', 'body' ]
    form    = ArticleAdminForm

    def save_model(self, request, obj, form, change):
         obj.author = "name Here"
         obj.save()

save\u model

方法提供了

HttpRequest

、一个模型实例、一个

ModelForm

实例和一个基于是添加还是更改对象的布尔值。在这里，您可以执行任何保存前或保存后操作

例如，要在保存前将

request.user

附加到对象，请执行以下操作：

ModelAdmin.save_model(self, request, obj, form, change)

from django.contrib import admin

class ArticleAdmin(admin.ModelAdmin):
    def save_model(self, request, obj, form, change):
        obj.user = request.user
        super().save_model(request, obj, form, change)
