第二編輯

這是syncdb

Syncing... 
Creating tables ... 
Installing custom SQL ... 
Installing indexes ... 
No fixtures found. 

Synced: 
> django.contrib.auth 
> django.contrib.contenttypes 
> django.contrib.sessions 
> django.contrib.sites 
> django.contrib.messages 
> django.contrib.admin 
> south 
> demo_project.profiles 

Not synced (use migrations): 
- easy_thumbnails 
- guardian 
- userena 
- userena.contrib.umessages 
(use ./manage.py migrate to migrate these) 

輸出這是./manage.py migrate

Running migrations for easy_thumbnails: 
- Nothing to migrate. 
- Loading initial data for easy_thumbnails. 
No fixtures found. 
Running migrations for guardian: 
- Nothing to migrate. 
- Loading initial data for guardian. 
No fixtures found. 
Running migrations for userena: 
- Nothing to migrate. 
- Loading initial data for userena. 
No fixtures found. 
Running migrations for umessages: 
- Nothing to migrate. 
- Loading initial data for umessages. 
No fixtures found. 

輸出請注意，eventhough我看到錯誤，用戶名和電子郵件被保存在數據庫中。

如果我登錄，它說：your account has been disabled

，如果我嘗試重置密碼，它說

That e-mail address doesn't have an associated user account. Are you sure you've registered?

Answer 1

我認爲你需要刪除你的數據庫。然後在新鮮的數據庫上再次執行manage.py syncdb和manage.py migrate。當你運行manage.py migrate它不應該給你你發佈的輸出。您的輸出不會更改或創建任何表格，這可能是問題。也許你需要的表格尚未創建。

1. This is what the output should look like after a manage.py syncdb.
2. This is what the output should look like after a manage.py migrate.

你應該有21個表格用於提供userena的demo_project。

---

對於一般幫助的步驟來獲得這個項目的工作應該是。

1. 創建虛擬環境，並pip install django-userena
2. 拉出附帶userena
3. 激活virtualenv中，cd到項目目錄的demo_project，做你的manage.py syncdb和manage.py migrate
4. 運行該項目

---

我已經完成了這個，現在可以確認t如果完成這些步驟，則demo_project將起作用。

*請記住，如果您在/accounts/signup/頁面上註冊用戶。該用戶默認情況下將無法登錄/admin/。除非您在管理員中給他一個配置文件，否則您的超級用戶將無法訪問/accounts/(profile)/下的個人資料。

Answer 2

你需要運行執行syncdb：manage.py syncdb

你已經計算出你還需要使用各種南方的命令。

現在有兩個問題出現：你是否仍然在跑南（我假設你是）後出現這些錯誤;其次，錯誤消息（Exception Value: (1146, "Table 'demo_project.userena_userenasignup' doesn't exist")）中指定的表是否確實存在？檢查數據庫以確定表是否存在，如果存在，是否存在於正確的數據庫中。
