In this use case you will learn how to build a Sandwich order management system using Table Grid Next Generation app.

You will also learn how to use external datasource in TGNG app and how to use external data in a select list in a grid column configuration:

Contents

Introduction

(info) The Sandwich order management is using an external datasource to collect the sandwich list that our restaurant will propose to customers. Our restaurant will use a Jira project to manager the sandwich orders from customers: each issue in the Jira project will be an order.

In order to use the data from an external datasource, you will have to use an external database system such as: MySQL, Postgres, SQL Server, etc. In this example, we will use MySQL as our external database system.

Prerequisites

  • User logged into their account, installed Table Grid Next Generation Server / Datacenter app

  • User created a related Jira project

  • User had the admin role on Jira 

  • User had a database system such as: MySQL, Postgres, SQL Server, etc.

Post-condition

  • User can use the grid to update related information for the list of items

  • User can create issues using the Sandwich grid

  • User can download/upload the Configuration for personal usage

  • User can add more columns to support the order management such as: total, amount,..

Conditions

  • Required fields are marked with a red asterisk *

  • User can use formulas in Table Grid Next Generation as a separate column or as an aggregation option for other column types. User can input formulas inside the embedded JavaScript Editor and get results on the grid view. The grid can process formula logic and display formula results. Error types in the formula column type

#error - syntax error

#type - operation error (operation could not be executed using different column types)

  • User have to set the name of Column to be an exact match with Column of the database.

User need to type the correct statement for the “SQL query”. For example:

SELECT column1, column2, ...

FROM table_name;

  • Each grid must contain at least 1 column, or else it will show the pop-up message “table-config-column-config-required”

Use case Flow Diagram

1. Create database in MySQL

To create a database in MySQL, we expect that you are connected to MySQL using a terminal in Linux / Mac or a batch command in Windows.

Here is the database that we will create using SQL language.
The database is called SANDWICH.

CREATE DATABASE SANDWICH;
use SANDWICH;

Here is the table that we will create in order to store our sandwiches data.
The table is called sandwich_menu

CREATE TABLE sandwich_menu(
sandwich_id SERIAL PRIMARY KEY,
sandwich_name VARCHAR(45),
sandwich_price DECIMAL(5,2)
);

2. Insert data in MySQL table

After creating the database and the table, we can now insert data into the recently created table.

INSERT INTO sandwich_menu
VALUES (1,'Lemon pepper chicken',1.95),
(2,'Chicken tikka with minted mayo',1.95),
(3,'Chicken and bacon',1.95),
(4,'Cajun chicken',1.95),
(5,'Chinese chicken',1.95),
(6,'BBQ chicken',1.95),
(7,'Mexican chicken',1.95),
(8,'Tuna mayo',1.65),
(9,'Tuna crunch',1.85),
(10,'Egg mayo',1.5),
(11,'Egg mayo & crispy bacon',1.95),
(12,'Prawn & marie rose sauce',2.2),
(13,'Cheese',1.3),
(14,'Cheese mix',1.6),
(15,'Ham',1.8),
(16,'Beef',1.8),
(17,'Corned beef',1.8),
(18,'Turkey',1.8); 

3. Configure a grid using Table Grid Next Generation app

Basic flow

Action

1
