的Django/Postgres的：事務管理塊未決的COMMIT/ROLLBACK

Question

我想運行（從Django的擴展命令）manage.py sqldiff MYAPP結束了，但我得到了以下錯誤：

Traceback (most recent call last): 
    File "manage.py", line 11, in <module> 
    execute_manager(settings) 
    File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 438, in execute_manager 
    utility.execute()

    self.__exit__(None, None, None) 
    File "/usr/local/lib/python2.7/dist-packages/django/db/transaction.py", line 207, in __exit__ 
    self.exiting(exc_value, self.using) 
    File "/usr/local/lib/python2.7/dist-packages/django/db/transaction.py", line 302, in exiting 
    leave_transaction_management(using=using) 
    File "/usr/local/lib/python2.7/dist-packages/django/db/transaction.py", line 56, in leave_transaction_management 
    connection.leave_transaction_management() 
    File "/usr/local/lib/python2.7/dist-packages/django/db/backends/__init__.py", line 115, in leave_transaction_management 
    raise TransactionManagementError("Transaction managed block ended with " 
django.db.transaction.TransactionManagementError: Transaction managed block ended with pending COMMIT/ROLLBACK 

manage.py runserver命令，shell，shell_plus都可以正常工作，但sqldiff命令會窒息。我曾嘗試過：

• restart postgres server
• manually connect to postgres from shell via psycopg2, ran connection.rollback(), and connection.commit()

但是錯誤仍然存​​在。

歡迎任何關於可以做什麼的想法！

乾杯，

我更新了sqldiff造成類似問題的issue。你最好的選擇可能是從github repository獲得django-extensions並做一些調查。編輯sqldiff.py並註釋掉交易代碼裝飾find_differences方法：

# @transaction.commit_manually 
def find_differences(self): 
... 
#    transaction.rollback() # reset transaction 
... 
#    transaction.commit() 

現在你真正的問題應該被揭露出來，不再受交易異常掩蓋。
