下降后的Django不能执行syncdb /创建数据库

Question

我想重置数据库并发出DROP DATABASE接着是创建数据库 由Django应用程序通过psycopg2访问的PostgreSQL服务器上。

当我做./manage.py执行syncdb我得到以下错误：

(prod)root@ns204612:/home/someproject/prod/django-mingus/mingus# ./manage.py syncdb
Traceback (most recent call last):
  File "./manage.py", line 16, in <module>
    execute_manager(settings)

    utility.execute()

    output = self.handle(*args, **options)

    return self.get_table_list(cursor)
  File "/home/someproject/prod/lib/python2.6/site-packages/django/db/backends/postgresql/introspection.py", line 30, in get_table_list
    AND pg_catalog.pg_table_is_visible(c.oid)""")
  File "/home/someproject/prod/lib/python2.6/site-packages/django/db/backends/util.py", line 19, in execute
    return self.cursor.execute(sql, params)
psycopg2.InternalError: current transaction is aborted, commands ignored until end of transaction block

和在PostgreSQL的日志I得到了以下错误：

2010-01-24 01:08:02 CET ERROR:  relation "django_site" does not exist
2010-01-24 01:08:02 CET STATEMENT:  SELECT "django_site"."id", "django_site"."domain", "django_site"."name" FROM "django_site" WHERE "django_site"."id" = 1  ORDER BY "django_site"."domain" ASC

                    WHERE c.relkind IN ('r', 'v', '')
                        AND n.nspname NOT IN ('pg_catalog', 'pg_toast')
                        AND pg_catalog.pg_table_is_visible(c.oid)

2010-01-24 01:08:02 CET LOG:  unexpected EOF on client connection

我怎么能解决这个问题吗？

Answer 1

这样做的原因是，其中使用由Django的明格斯django的请求的问题。在执行syncdb Django的做一些分贝反省和相关的进口提出了这个例外。如果你是拉无论从Django的请求或者Django的明格斯最新位，你会没事的。

Answer 2

尝试重置你的数据库像./manage.py复位your_app

Answer 3

我有同样的问题，并跟踪它到提交在2979ea3d4541f7b3c51c17e160bc95b468ac999b上的django-明格斯

如果您重置提交2f7eb8de7e2cb1c776e801a40f008048fcbb6d36，同步应该发生的罚款。

Answer 4

当它遇到其中postgres的引发错误和直到当前事务不会中止不要运行其它查询错误

MySQL不失效当前事务。在这种情况下，必须杀死交易或与该事务ID提交
