Describe the feature
比如业务写dao层的时候，经常函数传进来的是ctx和结构体参数
type A struct {
A string filter:"col:a;opr:like"
B string filter:"col:b;opr:eq"
C int
}
是不是可以根据结构体的tag标签定义数据库字段值和判断条件去实现 我看使用Scopes这个api可以实现
实现以后大概长这样
db.Model(&A{}).Scopes(func (db gorm.DB) gorm.DB{
scope := xxx() # 这里做一些逻辑
return db.Where(scope)
})
Motivation
可以作为一个特性，方便curd happy

The gorm Scopes implementation concatenates the where condition sql according to the tag of the passed struct Describe the feature For example, when a business writes the dao layer, ctx and structure parameters are often passed in by functions type A struct { A string filter:"col:a; opr:like" B string filter:"col:b; opr:eq" C int } Is it possible to define database field values and judgment conditions according to the tag tag of the structure to achieve I see Scopes this api can be achieved This is what it looks like when implemented db.Model(&A{}).Scopes(func (db gorm.DB) gorm.DB{ scope := xxx() # Do some logic here return db.Where(scope) })
Motivation Can be used as a feature to facilitate curd happy

似乎要自己去自定义函数实现
