django.db.models.base.py中的meta.local_fields設置在哪裏？

Question

，我發現了錯誤： 異常值：（1110，「列‘關於’指定了兩次」）

當我回顧Django的錯誤頁面，我注意到，自定義模式的用戶，似乎是附加到列表兩次。

這似乎是這裏發生在Django/DB /模型/ base.py在base_save（）：

values = [(f, f.get_db_prep_save(raw and getattr(self, f.attname) or f.pre_save(self, True))) for f in meta.local_fields] 

這是Django的錯誤頁面顯示的值是：

values = [(<django.db.models.fields.CharField object at 0xa78996c>, u'kallie'), 
(<django.db.models.fields.CharField object at 0xa7899cc>, ''), 
(<django.db.models.fields.CharField object at 0xa789a2c>, ''),

# at this point User model customizations repeats itself 
(<django.db.models.fields.BooleanField object at 0xa663b0c>, False), 
(<django.db.models.fields.CharField object at 0xaa1e94c>, None),

(<django.db.models.fields.CharField object at 0xaa1e40c>, 'b5ab1603b2308050ebd62f49ca75bca1'), 
(<django.db.models.fields.SmallIntegerField object at 0xa8c6d8c>, 0), 
(<django.db.models.fields.SmallIntegerField object at 0xaa2378c>, 0), 
(<django.db.models.fields.SmallIntegerField object at 0xaa237ac>, 0),

(<django.db.models.fields.DateTimeField object at 0xaa2380c>, u'2010-02-03 14:54:35'), 
(<django.db.models.fields.CharField object at 0xaa2384c>, ''), 
(<django.db.models.fields.URLField object at 0xaa2388c>, ''),

(<django.db.models.fields.DateField object at 0xaa2390c>, None), 
(<django.db.models.fields.TextField object at 0xaa2394c>, '')] 

由於這個應用程序在生產中，我無法弄清楚如何使用pdb.set_trace（）來查看save_base中發生了什麼。

到用戶自定義是：

User.add_to_class('email_isvalid', models.BooleanField(default=False)) 
    User.add_to_class('email_key', models.CharField(max_length=16, null=True)) 
    User.add_to_class('reputation', models.PositiveIntegerField(default=1)) 
    User.add_to_class('gravatar', models.CharField(max_length=32)) 
    User.add_to_class('email_feeds', generic.GenericRelation(EmailFeed)) 
    User.add_to_class('favorite_questions', models.ManyToManyField(Question, through=FavoriteQuestion, related_name='favorited_by'))     
    User.add_to_class('badges', models.ManyToManyField(Badge, through=Award, related_name='awarded_to')) 
    User.add_to_class('gold', models.SmallIntegerField(default=0)) 
    User.add_to_class('silver', models.SmallIntegerField(default=0)) 
    User.add_to_class('bronze', models.SmallIntegerField(default=0)) 
    User.add_to_class('questions_per_page', models.SmallIntegerField(choices=QUESTIONS_PER_PAGE_CHOICES, default=10))        
    User.add_to_class('last_seen', models.DateTimeField(default=datetime.datetime.now))      
    User.add_to_class('real_name', models.CharField(max_length=100, blank=True)) 
    User.add_to_class('website', models.URLField(max_length=200, blank=True)) 
    User.add_to_class('location', models.CharField(max_length=100, blank=True)) 
    User.add_to_class('date_of_birth', models.DateField(null=True, blank=True)) 
    User.add_to_class('about', models.TextField(blank=True)) 

Django1.1.1 Python 2.5的

Answer 1

我有同樣的問題。在我的情況下，代碼被執行了兩次。我有以下情況：

在一個應用程序：

from apps.accounts.models import User 

而在另一個應用程序：

from accounts.models import User 

自定義代碼是賬戶/ models.py模塊中，它被執行死刑兩次。
