如何在django管理頁面中填充datefield？

Question

嘗試了以下內容：

from datetime import datetime 
class ArticleAdmin(admin.ModelAdmin): 
    prepopulated_fields = {'slug': ('title',), 'pub_date':(datetime.now()) } 

這就提出：

錯誤：

<class 'news.admin.ArticleAdmin'>: (admin.E028) The value of 'prepopulated_fields' refers to 'pub_date', which must not be a DateTimeField, ForeignKey or ManyToManyField. 
<class 'news.admin.ArticleAdmin'>: (admin.E029) The value of 'prepopulated_fields["pub_date"]' must be a list or tuple. 

Answer 1

你被遺忘的元組的逗號。

from datetime import datetime 
class ArticleAdmin(admin.ModelAdmin): 
    prepopulated_fields = {'slug': ('title',), 'pub_date': (datetime.now(),) } 

Answer 2

prepopulated_fields不接受DateTimeField字段，ForeignKey的，也不ManyToManyField領域。
