Zhonglu,

Created a couple of table components with queries against our DB2 database on the iSeries. Noticed that it is consistently only returning 1000 rows of data. I don't see anywhere to configure number of rows returned. Is this a hard-coded limitation?

Thanks,

Mike

For example.
User account belong to USA can only see USA data and UK to UK data etc.

Metabase enterprise version implement RLS maybe like this:

1. Add additional global K/V attributes to User.
2. Query append all those K/V parameters.

Save each row width scale when editing table data

Trying to set this up for a Mysql Data Source required some trial and error in the Data Source configuration. It could be useful to others to add to the documentation/readme some notes on that.

After downloading the JDBC Mysql connector and placing it in jdbc-drivers according to the instructions, In Data Source I had to set the Connection Url to jdbc:mysql://[ip]:[port]/[db] but more importantly I had to set the Driver Class Name to com.mysql.cj.jdbc.Driver.

Attempting to Ping the database gives me a ERROR: java.sql.SQLException: SQL String cannot be empty but I can use the Data Source for Reports.

登录几分钟，就会自动退出登录，
分享连接打开显示 The report is no longer available.

按照文档docker安装的

使用docker注意加驱动程序mssql可能会连接错误，需要到容器中修改java.security屏蔽3DES_EDE_CBC

1、mysql驱动问题
Loading class com.mysql.jdbc.Driver'. This is deprecated. The new driver class is com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

2、导出cvs显示乱码，而且文件名无法修改

It is possible and common to set up postgres to trust local users to connect to their own databases with no password. Poli does not allow for this. Even if the username is left blank:

It still tries to connect with an empty username (whereas it should connect without trying username/password auth):

I'm able to connect to the same database with psql and no username/password:

$ psql culturecounts
psql (9.4.22)
Type "help" for help.

culturecounts=# 

is there setting to configure that another PC can access this Poli on the same LAN ?

best regards

1、当设置fileter后为slicer后，在query里编写自己的查询条件，但是slicer只是多选，能否添加一个下拉组件。谢谢

2、当数据量很大时，默认的1000行加载不太满足，
解决方案：能否让用户获取 “当前页数”和“下一页数” 来让用户实现真分页。谢谢

Jar file runs, but login doesn't work
Here's the config file on windows:

Config the absolute path to poli.db

For example, jdbc:sqlite:/home/poli/poli.db or jdbc:sqlite:c:/poli/poli.db

spring.datasource.url= jdbc:sqlite:c:/tmp/poli-0.11.0/db/poli.db

The maximum number of data source pool size

poli.datasource-maximum-pool-size=50

The maximum number of records returned in the JDBC result set. Default value is -1 which returns unlimited rows.

poli.maximum-query-records=-1

The display language.

poli.locale-language=en

Allow to run multiple SQL query statements in the query editor. If there are multiple SQL statements, only the

last one will return query results.

poli.allow-multiple-query-statements=false

PDF export server URL. Check export-server/poli-export-server.js for more details.

poli.export-server-url=http://127.0.0.1:6689/pdf

Here's the error from server.txt

Seems like projects that have a docs site external to their repo (e.g. tig, pipx) will put those in the repo's description as well.

It would be very useful if you can print the reports generated by poli

Apply some CSS media queries to be able to print the report. Also responsive to work well on tablet and mobile devices.

Would be great if we could use map components, like heat maps with basemaps (like OpenStreetMap) - based on lat/long or spatial fields.

中文环境时添加组件选择静态、图表、过滤器子类型都不能选择，这应该是个BUG吧，调成英文没问题

You can export a chart contents to CSV but not a table? This project is 99% of what we need for some internal reporting, this would be the remaining 1%...

Great project, btw. Been using ART (Another Reporting Tool), but your report creation process is much easier for end users.

Does the data source support Oracle? How to create a connection URL and other information?

数据报表为table ，当数据增多后，下拉滚动看数据后，表头的字段看不到了，能否固定一下表头，滚动数据后，表头不滚动

纯表格的改进需求，表格自动翻页或者是自动滚动，表格填充颜色，可以当生产展览板，工厂或者监控平台展示数据，直接电视机打开网页全屏显示充当看板。

目前把0.5.0的数据库复制到0.6.0中报了很多错误

any suggetion. i am using the below drivers in drivers folder.
mssql-jdbc-7.2.0.jre8.jar

with below driver class name:
com.microsoft.sqlserver.jdbc.SQLServerDriver

Would be great if we could integrate with existing Keycloak instance and grab it's roles and users as of built-in ones.

It would be nice to be able to have a drill through that will refresh only the current report and not go to a different report. Currently, if I add a drill through and point it to the current report, I still need to click refresh to be able to update the other chart's data.

Thank you developing this software.

Hey Folks,

Thanks so much for using Poli! We'd like to hear more about how you use Poli in your product/company/organization/project and how it helps to solve your problems.

Feel free to leave your product/company/organization/project information below so we can show them on our website(coming soon) and readme file!

Thanks again!

Poli is awesome project, thank you.

Can you add default value for filter commponent? Sometimes parametr without value will cause heavy query or internal error.

我修改了一版源码，其中涉及到一个私有jar包，已经pr，请看下是否合并

1.安全问题：当分享一个报表给其他应用系统时，url为：http://localhost:6688/poli/workspace/report/fullscreen?$toReport=reportname&$apiKey=apikey
这里的$apiKey目的是登录验证，但是也带来一个问题，我用以下地址：
http://localhost:6688/poli/workspace/report?$apiKey=apikey
同样可以访问分享人的report页面，导致报表权限泄露。如下图（未登录状态）：
http://ww1.sinaimg.cn/large/006y4X83gy1g5k2lykea1j31hc0smgn9.jpg
2. i18n问题：当分享报表时，使用的是默认en语言，不是应用定义的zh语言。

by the way ， @shzlw ，这个项目挺好，多谢开源！

Hi,
How I can retrieve password admin or any password ?
Same option with "lost passsword" in login page ?

Is there a way to export the data into a pdf format?

How hard would it be to create a war instead of a jar? I want Poli to run along side other war files within a tomcat server.

I am using Windows for server. I have been setting inbound port in the firewall, but still can't show the page. On localhost is working properly.
I have an idea, how to split IP:6688/static/js/2.39a8b735.chunk.js ? because that file size is 1.8 MB

Thanks in advance

目前的报表列表是一下子罗列所有报表，是否以目录树方式存放会更好些？

Would it be possible to create a Dynamic component type that allows for a query input and a plain text, or html output can can be customized to display the query results?

example:
Component to display the number of currently active sessions.
Currently the only way to achieve this is to put it out to a table.

Was able to connect to AWS Redshift using a Postgres compatible JDBC driver (https://docs.aws.amazon.com/redshift/latest/mgmt/configure-jdbc-connection.html)

However, my data is partitioned into multiple schemas. Need to select the schema before running the query. e.g.

set search_path to mySchema;
select count(*) from myTable;

The error I get is:
Internal Server Error: PreparedStatementCallback; bad SQL grammar [set search_path to xyzz; select * from....

Please suggest a way to do this either while creating the query or when setting up the data source (I can then create multiple datasources - one database per schema.)

你好，我想在报表配置语句中，限制当前登录的用户只能查看自己归属的区域数据，应该要怎么配置？

First of all, thanks. That is a very interesting project you made. I setup the mysql driver jar in the jdbc-drivers folder in the project.

When I added a datasource and ping it works well. And then made a report, it works very well when check the datasorce schema. But when I edit the query to fetch data, it went wrong with this error:

My platform is Windows. And I have already added the mysql driver jar into the java classpath. What I'm curious is it works well for datasource schema read, but failed for query execution, due to driver load failed. Any idea?

在Report中定义drill through，运行时点击进入钻取的report，table的数据查询范围是全部，钻取条件不起作用，只有点击apply filters才能起作用，钻取的参数在url中能够看到。

图表配置sql的时候，用了as但是列名称还是原始的数据库里的字段名称，现阶段采用cast的方式进行转换后，把展现的列名变了。

我下载了你的源码，但是在启动过程中并没有反应.

0.9.0中postgresql的p_report、p_component、p_canned_report表中定义了相关json类型，虽然有bug，但是修正下即可，例如ReportDao的insert：
PGobject jsonObject = new PGobject();
jsonObject.setType("json");
try {
jsonObject.setValue(style);
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
params.addValue(Report.STYLE, jsonObject);
0.9.1中将相关json类型都变更为varchar了，这样做会产生一些问题：
长度限制、varchar不能像json那样进行检索等等

从0.10.0 升级到0.11.0 后 ，poli 都为docker 启动
11版mysql数据源无法连接，10版数据源正常

myql版本 5.6.46

DB：postgres

创建报表、数据源、群组时报异常：
The getKey method should only be used when a single key is returned. The current key entry contains multiple keys:

创建用户时没有问题。

原因：
创建时会返回table的所有列，直接通过keyHolder.getKey().longValue()就会报异常，
所以其他的dao中都应该按照userdao的代码修改下：
KeyHolder keyHolder = new GeneratedKeyHolder();
npjt.update(sql, params, keyHolder, new String[] { User.ID});
return keyHolder.getKey().longValue();
而不是
KeyHolder keyHolder = new GeneratedKeyHolder();
jt.update(connection -> {
PreparedStatement ps = connection.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);
ps.setString(1, name);
return ps;
}, keyHolder);
return keyHolder.getKey().longValue();

eclipse加载项目源码后，怎么通过run spring boot app的形式启动？或者有相关说明不？
想通过二次开发追加些内容，通过ide进行调试。
不胜感激。
