在Django中OneToOne相關的自動填充子表

Question

我對django相當陌生，而且我在Django的構建User模型django.contrib.auth.model的擴展子表中遇到問題。子表是UserProfile，並從User繼承。 （請參閱下面的我的型號）

我無法真正弄清楚如何將數據放在這些表中，除非管理網站顯然不夠好。

我會得到我的用戶對象併爲它指定一些變量，比如說，u = User.objects.get(username = 'jane_smith'然後嘗試使用up = u.userprofile命令到達子表中的數據。我獎勵了以下錯誤：DoesNotExist: UserProfile matching query does not exist.

我嘗試通過終端獲得解決該問題通過手動輸入數據，與up = UserProfile(user_ptr = User.objects.get(username = 'jane_smith'), country = 'USA', num_meals_hosted = 0, cook_rating = 5, image = None, zipcode =91011)其次up.save()

但是，我得到了下面的堆棧跟蹤

>>> up.save() 
Traceback (most recent call last): 
File "<console>", line 1, in <module> 
File "/Library/Python/2.6/site-packages/django/db/models/base.py", line 460, in save

File "/Library/Python/2.6/site-packages/django/db/models/base.py", line 504, in save_base 
self.save_base(cls=parent, origin=org, using=using)

rows = manager.using(using).filter(pk=pk_val)._update(values)

return query.get_compiler(self.db).execute_sql(None) 
File "/Library/Python/2.6/site-packages/django/db/models/sql/compiler.py", line 869, in execute_sql 
cursor = super(SQLUpdateCompiler, self).execute_sql(result_type)

return self.cursor.execute(sql, params) 
File "/Library/Python/2.6/site-packages/django/db/backends/mysql/base.py", line 86, in execute 
return self.cursor.execute(query, args)

self.errorhandler(self, exc, value)

raise errorclass, errorvalue 
IntegrityError: (1062, "Duplicate entry '' for key 'username'") 

任何幫助？只想找到一種通過API將數據放入這些表中的方法。以下是我的模特。如果需要，歡迎在評論中發佈更多信息。

from django.db import models 
from django.contrib.auth.models import User 

class UserProfile(User): 
    address = models.CharField(max_length=100, blank=True) 
    city = models.CharField(max_length = 50, blank=True) 
    state = models.CharField(max_length = 15, blank=True) 
    zipcode = models.IntegerField(blank=True) 
    country = models.CharField(max_length = 50, blank=True) 
    num_meals_hosted = models.IntegerField() 
    cook_rating = models.IntegerField() 
    diet_restrict = models.CharField(max_length = 600, blank=True) 
    blurb = models.CharField(max_length = 10000, blank=True) 
    website = models.URLField(blank=True) 
    image_height = models.IntegerField(blank = True) 
    image_width = models.IntegerField(blank = True) 

    def __unicode__(self): 
     return self.id
