visualis's Issues

Widget Chart Driven - The table size is changed to "Small" by default

1. Demand analysis
   After entering the Widget, after selecting the picture component, in the style bar, the default size of the table is "large", which needs to be changed to "small" by default.
2. Front section side reconstruction
   It is necessary to change the default value of the modified code in the previous paragraph, and the default value is changed to small.

OPTIMIZATION: In widget page, don't show pagination component when data is emoty

by jdbc data source struct widget，widget not rendering

bug describe: by jdbc data source struct Widget，getdata interface response data，but canvas rendering not show.
analysis: normal ，select sum(xx) from table group by xx。but visualis send sql is select * from table

Workflow should end immediately when widget execution fails

1. Demand background
   The background of the bug is that when a widget fails to execute, there will still be a successful screenshot caused by the occasional display execution. This requirement needs to be verified to reproduce.
2. Rear end side modification
   It is necessary to sort out the screenshot logic to determine whether there is an execution failure label in the previous layer of the execution failure (tentative solution)
   A better solution is that when the screenshot accesses the URL, the backend will start a WebDriver process to access the URL screenshot address. When the requirements such as pixels appear, the screenshot will be executed. This will lead to a scene where a blank picture may appear in the screenshot.
3. Front section side reconstruction
   The previous paragraph needs to set the layer label, and the label execution fails.
   The update plan currently does not involve the transformation of the previous section.

[后端] The latest server code of Visualis

1. Adapt the latest Apache linkis 1.1.0 code.
2. Adapt to the latest DSS1.1.0.
3. Modify and adapt DSS workflow interface.

Function: In "Widget" page, the sequence of columns can be set, which means indicators can be put in front of dimensions.

BUG: Can't share an empty display correctly

Function: In "Widget" page, columns can be hidden

Support Widget list search

1. Demand background
   Due to the complex reports of some users, there are dozens of widget lists. If you want to find a widget when developing a widget, you can only browse it manually, and you cannot search for the widget.
2. Rear end side modification
   The backend will provide a search interface. (Tentatively, if the search function can be implemented in the previous paragraph)
3. Front section side reconstruction
   If the previous paragraph provides a search function. (The backend may not provide the search function)

Drag the Widget component from the dashboard page to prompt 'server internal error'

Steps

1. Add more than two Widget component
2. Drag the Widget component.

solution

1. vi visualis-server/conf/application.xml Database url configuration followed by an argument &allowMultiQueries=true
2. restart visualis-server

Function: Integrate widgets to dss workflow

visualis二次开发文档

麻烦问一下，有没有visualis的二次开发指导文档或者开发文档？
当前需要对visualis进行二次开发，涉及前后台修改，没有找到类似的文档

Upgrading Linkis to Apache Linkis does not involve related requirements

1. Demand background
   The inline version Linkis is upgraded to Apache Linkis, which does not involve related requirements.
2. Rear end side modification
   It is required to modify the Linkis dependency version for the backend.

Optimize the copy logic, the data source does not need to be copied

1. Demand background
   At present, after the source module is released, after exporting, importing and copying, a new version will be added in the development center. The data source records are generally configured once and then reused.
2. Rear end side modification
   The back-end replication logic needs to be optimized and the source version of the data source is not generated.
3. Front section side reconstruction
   This requirement does not involve modification of the preceding paragraph.

BUG: In widget page, the color property can't work because some of data from the server are different

Display component sidebar Widget name display optimization

1. Demand background
   On the Display page, the Widegt list on the right will be hidden when the Widget name is too long, making viewing the Widget less intuitive.
2. Rear end side modification
   No back-end modifications are involved for the time being.
3. Front section side reconstruction
   Support name adaptive full display.

Widget-Editor Settings-Multi-select drag and drop default value changed to "Yes"

1. Demand analysis
   At present, Widget click settings, multi-selection drag and drop defaults to "No", and needs to be changed to "Yes".
2. Front section side reconstruction
   The default value for modifying the logic code is "Yes".

本地启动前台，服务启动成功，无法正常使用

1.已按照前台编译要求，配置chrome浏览器跨域相关项
2.配置.env文件VUE_APP_MN_CONFIG_PREFIX=http://xxx:xx/api/rest_j/v1
3.本地编译web模块，使用npm run serve启动服务，服务启动正常
4.打开localhost:8080，进入登录页面
5.使用账号密码进行登录
登录成功后，会马上跳转回登录页面，同时提示“您尚未登录，请先登录!”，
查看接口，发现login接口返回正常（login successful(登录成功)），getBaseInfo接口返回401（You are not logged in, please login first(您尚未登录，请先登录)!）

[组织结构] Optimize project structure

1. Remove useless files and simplify project structure.
2. Optimized compilation and packaging.

dimension sort notwork 提示您sql代码可能有语法错误

Steps

1. add or edit wigetlist, select view
2. drag dimension， and select sort

DSS Update Item Description Visualis Sync Update Item Description

DSS Update Project Description Visualis Sync Update Project Description

1. Demand background
   The DSS side updates the project description, and Visualis updates the project description synchronously.
2. Rear end side modification
   It mainly involves DSS VisualisAppConn docking transformation.
3. Front section side reconstruction
   No front-end modifications are involved.

BUG：In widget page, function "sort" can't work

BUG: In widget page，add logic when response is empty

Function: In "Widget" page, table's width can be set by dragging or inputing number in configuration area

前端单独跑Visualis

本地拉取代码Visualis的master分支

The user checked the widget node again after the bill of lading and did not modify it, and then reported an error: Widget Updated after approved

Scenario: Although the user viewed the workflow without modification, and then saved it, the UpdateTime of the node will be greater than the B/L time.

[前端] Latest web Front-end code

1. fix compilation issues.
2. Sync latest modification point.

[DDL文件] Database file update

1. The latest database file updates, including table and field updates.

Background settings - the background color RGB is changed by default, and the display default value is changed to static mode

1. Requirement description
   For background settings, the default color value is changed from the previous RGB black value to RGB white.
2. Modification of the front section
   You need to modify the default value of this module of the Display component.

Function: watermask

The default entry of Widget is changed to icon-driven

1. Demand background
   At present, after Visuslis enters the Widget, the default is perspective-driven.
2. Front section side reconstruction
   The previous section needs to be modified. The default entry is icon driven.

Function: In "Display" page, labels can be named

BUG: In widget page, pivot chart cannot be changed into table normally

Support DSS delete project synchronization Visualis delete project

1. Demand background
   To delete a project on the DSS side, the Visualis project as a third-party node is not deleted. It needs to support the deletion of the project on the DSS side, and the Visualis side will also delete the project synchronously. (DSS can only delete Visualis projects created by DSS itself. Visualis can only delete projects created by itself)
2. Rear end side modification
   It mainly involves the deletion of the back-end side (in the design, the database logical deletion is mainly used, and real deletion is not performed.) After a new project is created on the DSS side, Visualis, as a third-party node, will also create the project synchronously. After DSS deletes the project, Visualis also deletes the project synchronously.
3. Front section side reconstruction
   A small delete icon is added, and the interface is attached separately. The pop-up window effect and deletion icon material are shown in Figure 2-3 (if the DSS project is deleted, a corresponding prompt will pop up not to allow deletion). Figure 2 shows the pop-up window prompt effect, and Figure 3 shows the small picture material.

OPTIMIZATION：In widget page columnConfigModal, width value needs to show in interger mode

Try replacing with Chrom for screenshots

1. Demand background
   In the Display preview, when the workflow is executed, a Minified React Error #31 will be reported occasionally. Need to locate whether it is a compatibility problem. https://www.jianshu.com/p/f0ac782e369c
   This version will replace the screenshot tool with Chromer, and you need to verify the correctness of the email.
2. Rear end side modification
   No back-end modifications are involved for the time being.
3. Front section side reconstruction
   No front-end modifications are involved.
   Remarks: The original Visualis already supports Chromer screenshots, you only need to verify the correctness of the mail function. If there is a problem, the requirement is left behind.

The field order of "Type/Numeric" in the Widget should be consistent with the order of the upstream temporary table

1. Defect Background
   The results and field information queried from the upstream temporary table are shown in the figure.
   The "Type/Numeric" that appears in the Widget may appear, and the fields in the area as shown below are inconsistent (the screenshots are consistent, and code and case verification are required)
2. Rear side modification
   The data returned by the back-end analysis interface, whether the book is in the same order as the data in the temporary table.
3. Modification of the front section
   It is necessary to check the data interfaces on both sides in the front section to see if there is any inconsistency caused by data sorting.

The version should only show the latest current version, the previous version does not need to show

1. Demand background
   At present, each component display of Visualis displays all versions, which will result in a lot of components displayed in the previous section, which will affect the user experience.
2. Rear side modification
   The backend side will filter the version, only the latest version will be displayed, and the previous version will not be displayed. (To be discussed: the current component names all have the project version and the workflow version number. The version information is in the component name. If the version information is changed, whether it needs to be removed when it is passed to the front end)
3. Modification of the front section
   This requirement does not involve modification of the preceding paragraph

表格设置隔行不同色

图表配置样式时，是否有可能设置隔行不同颜色？

Source does not need to generate version after release, Source should be reused

1. Defect Background
   For Source, the data source is immutable and can be reused. In the current logic, an immutable data source will be copied, resulting in many versions of the same data source.
2. Rear side modification
   The back-end side will reuse the data source to avoid duplicating the data source.
3. Modification of the front section
   This requirement does not involve modification of the preceding paragraph

Documentation update

1. Front-end and back-end compilation documentation.
2. Install and deploy documentation.
3. Documents for docking with DSS.
4. FAQ document.

Bug: In "Widget" page, there're some numbers close to each other.Need to separate them

[Tableau DeskTop][Bug修复]Tableau DeskTop数据读取和展示的结果不同

【需求背景】
用户在使用Tableau连接TDSQL数据库时，预览字段数据与实际在视图中展示的字段数据值不一致。

[Tableau DeskTop][Tableau Server][Bug修复]同一个视图，Tableau DeskTop与Tableau Server上字体展示不同

After the Widget is executed and published, the configuration binding fails

1. Defect Background
   When the DSS workflow is executed after the release, if you double-click to enter the widget node, only the configuration of the relevant indicators will be lost.
2. Rear side modification
   When the workflow is published, it will export, import and copy the workflow nodes. At present, the back-end code uses the widget's model field serial number as a string, which causes an exception in the previous parsing formula, and the back-end needs to modify the model field serial number logic.
3. Modification of the front section
   This requirement does not involve modification of the preceding paragraph.

想单独部署visualis，然后注册到linkis
