在manage.py migrate时,必须是关系django_site的所有者

Question

经过长时间搜索postgre,关于manage.py killorphant,关于django_site,没有什么能帮助我解决这个错误:

Synchronizing apps without migrations:
  Creating tables...
  Installing custom SQL...
  Installing indexes...
Running migrations:
  Applying sites.0002_auto_20150929_1444...Traceback (most recent call last):

    return self.cursor.execute(sql, params)
psycopg2.ProgrammingError: must be owner of relation django_site**

上述异常是以下异常的直接原因:

因此,在检查并重新检查后,django-site位于已安装的应用列表中site_id = 1; 我的数据库工作除了一些图像问题..那么我试图做一些迁移,但这个错误继续运行,我现在迫切希望找到问题.

有人对此有所了解吗？

Answer 1

用于django连接到数据库的数据库用户不是表的所有者.你需要在postgres shell上更改它,或者pgadmin3可以帮助你.

就像是:

ALTER DATABASE your_db OWNER TO your_django_db_user
ALTER TABLE django_site OWNER TO your_django_db_user

Answer 2

就我而言，我想将所有表所有权更改为db_user ，因此我执行以下脚本将所有表所有权更改为db_user。

打开你的外壳

sudo -s -u postgres

对于多个数据库：

export user="db_user"
export dbs="db1 db2"

然后

for db in $dbs; do
    psql -c "alter database $db owner to $user" $db;
done

for db in $dbs; do
    psql -c "alter schema public owner to $user" $db;
done

for db in $dbs; do
    tables=`psql -qAt -c "select tablename from pg_tables where schemaname = 'public';" $db`

    for tbl in $tables; do
        psql -c "alter table \"$tbl\" owner to $user" $db;
    done;
done

for db in $dbs; do
    seqs=`psql -qAt -c "select sequence_name from information_schema.sequences where sequence_schema = 'public';" $db`

    for seq in $seqs; do
        psql -c "alter table \"$seq\" owner to $user" $db ;
    done;
done

for db in $dbs; do
    views=`psql -qAt -c "select table_name from information_schema.views where table_schema = 'public';" $db`

    for view in $views; do
        psql -c "alter table \"$view\" owner to $user" $db ;
    done;
done

然后迁移

python manage.py migrate
