Project sorting of Online Exercise System Based on gin and Gorm

go/gin/gorm/mysql Wait for the environment to be built ; use first Navicat Create a new database gin_gorm_online_judge For this project , The contents are as follows: ：

Create a new question table in this library problem Here's the picture ：

Our normal project logic ( Project process ) It should be that after we define a table, we need to go to our gorm Put it in there model Also sync it to the past ;

We are Goland new directory models Catalog , Then build problem.go The file is shown below ：

problem.go The contents are as follows ：

package models

import "gorm.io/gorm"

type Problem struct {
    
	gorm.Model
	Identity   string `gorm:"column:identity;type:varchar(36);" json:"identity"`
	CategoryId string `gorm:"column:category_id;type:varchar(255);" json:"category-id"`
	Title      string `gorm:"column:title;type:varchar(255)" json:"title"`
	Content    string `gorm:"column:content;type:text" json:"content"`
	MaxRuntime int    `gorm:"column:max_runtime;type:int(11);" json:"max-runtime"`
	MaxMem     int    `gorm:"column:max_mem;type:int(11);" json:"max_mem"`
}

func (table *Problem) TableName() string {
    
	return "problem"
}

newly build user The table is as follows ：

newly build user.go as follows ：

package models

import "gorm.io/gorm"

type User struct {
    
	gorm.Model
	Identity string `gorm:"column:identity;type:varchar(36);" json:"identity"`
	Name     string `gorm:"column:name;type:varchar(100)" json:"name"`
	Password string `gorm:"column:password;type:varchar(32)" json:"password"`
	Phone    string `gorm:"column:phone;type:varchar(20)" json:"phone"`
	Mail     string `gorm:"column:mail;type:varchar(100)" json:"mail"`
}

func (table *User) TableName() string {
    
	return "user"
}

newly build category surface ：

newly build category.go file ：

package models

import "gorm.io/gorm"

type Category struct {
    
	gorm.Model
	Identity string `gorm:"column:identity;type:varchar(36);" json:"identity"`
	Name     string `gorm:"column:name;type:varchar(100);" json:"name"`
	ParentId int    `gorm:"column:parent_id;type:int(11);" json:"parent_id"`
}

func (table *Category) TableName() string {
    
	return "category"
}

newly build submit surface ：

newly build submit.go The documents are as follows ：

package models

import "gorm.io/gorm"

type Submit struct {
    
	gorm.Model
	Identity        string `gorm:"column:identity;type:varchar(36);" json:"identity"`
	ProblemIdentity string `gorm:"column:problem_identity;type:varchar(36)" json:"problem_identity"`
	UserIdentity    string `gorm:"column:user_identity;type:varchar(36)" json:"user_identity"`
	Path            string `gorm:"column:path;type:varchar(20)" json:"path"`
}

func (table *Submit) TableName() string {
    
	return "submit"
}

After the overall construction, the directory is as follows ：
