如何解决升级Apache Superset后出现错误-RuntimeError:在应用程序上下文之外工作
我刚刚升级到Apache Superset的最新版本。 当我使用命令启动Apache Superset时
gunicorn \
-w 10 \
-k gevent \
--timeout 120 \
-b 0.0.0.0:8088 \
--limit-request-line 0 \
--limit-request-field_size 0 \
--statsd-host localhost:8088 \
superset:app
respiter = self.wsgi(environ,resp.start_response)
File "/usr/local/superset/lib/python3.7/site-packages/werkzeug/local.py",line 376,in <lambda>
__call__ = lambda x,*a,**kw: x._get_current_object()(*a,**kw)
File "/usr/local/superset/lib/python3.7/site-packages/werkzeug/local.py",line 307,in _get_current_object
return self.__local()
File "/usr/local/superset/lib/python3.7/site-packages/flask/globals.py",line 52,in _find_app
raise RuntimeError(_app_ctx_err_msg)
RuntimeError: Working outside of application context.
This typically means that you attempted to use functionality that needed
to interface with the current application object in some way. To solve
this,set up an application context with app.app_context(). See the
documentation for more information.
...
我发现我可以将其更改为“ superset.app:create_app()”,如下所示:
gunicorn \
-w 10 \
-k gevent \
--timeout 120 \
-b 0.0.0.0:8088 \
--limit-request-line 0 \
--limit-request-field_size 0 \
--statsd-host localhost:8088 \
"superset.app:create_app()"
但是当我打开仪表板时,现在出现此错误:
File "/usr/local/superset/lib/python3.7/site-packages/MysqLdb/connections.py",line 239,in query

我已经搜索了更多的解决方案。似乎在使用db upgrade命令时,MysqL数据库没有通过升级得到纠正:
(superset) [root@host .superset]# superset db upgrade
logging was configured successfully
INFO:superset.utils.logging_configurator:logging was configured successfully
/usr/local/superset/lib/python3.7/site-packages/flask_caching/__init__.py:188: UserWarning: Flask-Cache: CACHE_TYPE is set to null,caching is effectively disabled.
warnings.warn("Flask-Cache: CACHE_TYPE is set to null,"
WARNI [alembic.env] sqlite Database support for Metadata databases will be removed in a future version of Superset.
INFO [alembic.runtime.migration] Context impl sqliteImpl.
INFO [alembic.runtime.migration] Will assume transactional DDL.
我没有看到任何错误吗?
当我调用init时,我得到了:
(superset) [root@host .superset]# superset init
logging was configured successfully
INFO:superset.utils.logging_configurator:logging was configured successfully
/usr/local/superset/lib/python3.7/site-packages/flask_caching/__init__.py:188: UserWarning: Flask-Cache: CACHE_TYPE is set to null,"

是因为超集需要MysqL的某些权限才能在表中进行更改?
希望有人可以进一步帮助我
谢谢
解决方法
我不知道为什么命令“ superset db upgrade”没有更新我的MYSQL数据库,但是我随后手动创建了这些字段和表,现在看来可以正常工作:
slices.schema_perm
tables.schema_perm
dbs.encrypted_extra
dbs.allow_cvas
dbs.server_cert
saved_query.extra_json
这些带有字段的表
CREATE TABLE `alerts` (
`id` int(11) NOT NULL,`label` varchar(250) DEFAULT NULL,`active` tinyint(2) DEFAULT NULL,`crontab` varchar(250) DEFAULT NULL,`sql` varchar(250) DEFAULT NULL,`alert_type` varchar(250) DEFAULT NULL,`recipients` varchar(250) DEFAULT NULL,`log_retention` varchar(250) DEFAULT NULL,`grace_period` varchar(250) DEFAULT NULL,`slice_id` int(11) DEFAULT NULL,`dashboard_id` int(11) DEFAULT NULL,`database_id` int(11) DEFAULT NULL,`last_eval_dttm` varchar(250) DEFAULT NULL,`last_state` varchar(250) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
ALTER TABLE `alerts`
ADD PRIMARY KEY (`id`);
CREATE TABLE `tab_state` (
`created_on` datetime DEFAULT NULL,`changed_on` datetime DEFAULT NULL,`extra_json` varchar(250) COLLATE utf8mb4_unicode_ci DEFAULT NULL,`id` int(11) NOT NULL,`user_id` int(11) NOT NULL,`label` varchar(250) COLLATE utf8mb4_unicode_ci DEFAULT NULL,`active` tinyint(1) DEFAULT NULL,`database_id` int(11) NOT NULL,`schema` varchar(250) COLLATE utf8mb4_unicode_ci DEFAULT NULL,`sql` varchar(250) COLLATE utf8mb4_unicode_ci DEFAULT NULL,`query_limit` varchar(250) COLLATE utf8mb4_unicode_ci DEFAULT NULL,`latest_query_id` int(11) NOT NULL,`autorun` varchar(250) COLLATE utf8mb4_unicode_ci DEFAULT NULL,`template_params` varchar(250) COLLATE utf8mb4_unicode_ci DEFAULT NULL,`created_by_fk` int(11) NOT NULL,`changed_by_fk` int(11) NOT NULL,) ENGINE=MyISAM DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
我不知道字段类型,所以也许有人可以为您提供正确的类型。
谢谢
