【中文标题】ProgrammingError:关系 django_session 的权限被拒绝【英文标题】:ProgrammingError: permission denied for relation django_session 【发布时间】:2014-08-19 20:53:09 【问题描述】:我最近在网站上遇到了 500 个错误。错误是ProgrammingError: permission denied for relation django_session
。
update_disable()
ajax 函数有时会发生这种情况。
这里是函数
def update_disable(request, song_pk, dj_name=None, view=None, genre=None):
song = Song.objects.get(pk=song_pk)
song.votes = song.votes + 1
song.save()
dajax = Dajax()
dajax.assign('.vote', 'disabled', 'disabled')
if dj_name:
request.session[dj_name] = True
elif genre:
print genre
request.session[genre] = True
else:
if view=="month":
request.session['month_voted'] = True
else:
request.session['trending_voted'] = True
request.session.set_expiry(604800)
visitor = get_obj_or_none(Visitor, last_session_key=request.session._session_key)
if visitor:
voter = get_obj_or_none(Voter, visitor=visitor)
if voter:
voter.vote_count += 1
voter.save()
else:
voter = Voter(visitor=visitor)
voter.save()
return dajax.json()
我似乎无法理解引发此错误的原因。有什么想法吗?
这是整个回溯

【问题讨论】:
您使用的是哪个数据库? @BurhanKhalid PostreSQL checkout你的数据库权限,好像你没有权限在django-session表中执行了一条sql, 【参考方案1】:如果您使用 Heroku PostgreSQL 作为数据库,您可能已达到行数限制。用命令行工具验证一下:
heroku pg:info -a <your_app>
=== HEROKU_POSTGRESQL_MAUVE_URL, DATABASE_URL
Plan: Hobby-dev
Status: Available
Connections: 0/20
PG Version: 10.6
Created: 2018-03-14 22:04 UTC
Data Size: 20.3 MB
Tables: 90
Rows: 13764/10000 (Write access revoked)
Fork/Follow: Unsupported
Rollback: Unsupported
Continuous Protection: Off
Billing App: xxxxxxxxx
Add-on: postgresql-silhouetted-xxx
Rows:
行告诉您写访问权限已被撤销:(Write access revoked)
。
【讨论】:
遇到这个问题,请问有解决办法吗 @AzeezBello 您需要升级您的数据库计划以增加容量或删除内容。【参考方案2】:如果您使用的是 Heroku、DJANGO、PostgreSQL
这个错误被解释为by Heroku here
heroku 提供的用于解决此问题的所有方法都需要您更新帐户。 为了避免这一切,我想告诉你如何解决这个问题
1.在本地机器上安装 POSTGRESSQL Heroku devcenter tutorial
2。获取您的 BATABASE 信息
$ heroku pg:info -a your-app-name
=== DATABASE_URL
Plan: Hobby-dev
Status: Available
Connections: 6/20
PG Version: 11.12
Created: 2019-09-10 23:20 UTC
Data Size: 11.8 MB
Tables: 33
Rows: 1064/10000 (In compliance)
Fork/Follow: Unsupported
Rollback: Unsupported
Continuous Protection: Off
Add-on: postgresql-********
注意最后一行(附加组件)我们将使用它
3.打开您的在线 PSQL 命令提示符
$ heroku pg:psql postgresql-******** --app your-app-name
将 '********' 替换为您的插件内容*
如果一切顺利,您已到达应用程序的 pqsl 命令提示符
4.删除 django_session 表
your-app-name::DATABASE=> DROP TABLE django_session;
5.创建一个新的 django_session 表
your-app-name::DATABASE=> CREATE TABLE django_session (
session_key varchar(40),
session_data text,
expire_date timestamptz );
6.退出
your-app-name::DATABASE=> \q
