Database

With GoFrame CLI tools, we could create a new project quickly and then configure the compose file for docker.

Create project

Use the following command to create your project:

gf init bootcamp -u

Or change the bootcamp to whatever you want for your project name.

ℹ️

GoFrame project have its own folder structure, we may talk about some methodology later.

Create a database folder in manifest folder, you can store you database related code or settings here.

Setup

Create docker-compose file in your project root folder:

docker-compose.yaml

version: "3"
services:
  database:
    image: mariadb:10.3
    environment:
      MYSQL_ROOT_PASSWORD: R0OTp@ssword
      MYSQL_DATABASE: bootcamp
      MYSQL_USER: dbadmin
      MYSQL_PASSWORD: Password
      TZ: Asia/Shanghai
    healthcheck:
      test: mysqladmin ping -u dbadmin -pPassword
    volumes:
      - ./manifest/database/:/var/database
      - database:/var/lib/mysql
    command:
      mysqld --default-time-zone=Asia/Shanghai --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
    ports:
      - "3306:3306"
volumes:
  database:

ℹ️

we are using mariadb as database in this file, you could also change to any other database supported by GoFrame.

Since you are using local database, you need to do following steps by yourself:

Create database bootcamp
Create account for your project
- username: dbadmin
- password: Password
Add permissions to created account

⚠️

Using root account is not recommended

Schema

Since GoFrame is an enterprise-class framework, its design principle is not allowing developers to change schema when developing. Therefore, we need to create a database schema first. You may also find other project for database schema management:

Schema management

Migration when developing

For simplicity, we will just use the following SQL to create the schema first, you may discover other methods later:

manifest/database/initial.sql

CREATE TABLE IF NOT EXISTS `users`
(
    `uid` varchar(10) NOT NULL UNIQUE COMMENT 'User Unique ID',
    `username`  varchar(25) NOT NULL UNIQUE COMMENT 'User Name',
    `password`  varchar(45) NOT NULL COMMENT 'User Password',
    PRIMARY KEY (`uid`),
    INDEX `idx_username` (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE utf8mb4_unicode_ci;

CREATE TABLE IF NOT EXISTS `messages`
(
    `id` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT 'Message ID',
    `user_uid`  varchar(10) NOT NULL COMMENT 'Message Sender Uid',
    `content`  varchar(100) NOT NULL COMMENT 'Message Content',
    `created_at` datetime DEFAULT NULL COMMENT 'Created Time',
    `updated_at` datetime DEFAULT NULL COMMENT 'Updated Time',
    `deleted_at` datetime DEFAULT NULL COMMENT 'Soft deleted Time',
    PRIMARY KEY (`id`),
    FOREIGN KEY (`user_uid`) REFERENCES `users`(`uid`) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE utf8mb4_unicode_ci;

Initialize tables

Start the database container with:

docker compose up -d --build

Enter the container and execute the sql file in var/database folder:

mysql -u dbadmin -pPassword bootcamp < /var/database/initial.sql

Use the following command to execute the sql file:

mysql -u dbadmin -pPassword bootcamp < /var/database/initial.sql

Insert data

Enter the container and execute the following command to enter your database:

mysql -u dbadmin -pPassword bootcamp

Use the following command to insert data to users table:

INSERT IGNORE INTO `users`(`uid`, `username`, `password`)
VALUES ('0000000000', 'admin', '123456');

Check the data with:

SELECT * FROM `users`;

uid	username	password
0000000000	admin	123456

ℹ️

Saving password without encryption is not recommended, you could add it later.
This record is needed for CRUD operations, since we have added FOREIGN KEY in messages table.
