type Extra map[string]interface{}

func (e Extra) Scan(value interface{}) error {
     switch v := value.(type) {
     case string:
          return json.Unmarshal([]byte(v), e)

}
type translate

if sql type is not match, toyorm will ignore it in Sql Operation

you can use <type:sql_type> field tag to specified their sql type

the following type will auto translate to sql type

Go Type sql type
bool BOOLEAN
int8,int16,int32,uint8,uint16,uint32 INTEGER
int64,uint64,int,uint BIGINT
float32,float64 FLOAT
string VARCHAR(255)
time.Time TIMESTAMP
[]byte VARCHAR(255)
sql.NullBool BOOLEAN
sql.NullInt64 BIGINT
sql.NullFloat64 FLOAT
sql.NullString VARCHAR(255)
sql.RawBytes VARCHAR(255)

special fields

  1. special fields have some process in handlers, do not try to change it type or set it value
Field Name Type Description
CreatedAt time.Time generate when element be create
UpdatedAt time.Time generate when element be update/create
DeletedAt *time.Time delete mode is soft

field tags

  1. tag format can be <key:value> or <key>

  2. the following is special tag

Key Value Description
index void or string use for optimization when search condition have this field,if you want make a combined,just set same index name with fields
unique index void or string have unique limit index, other same as index
primary key void allow multiple primary key,but some operation not support
- void ignore this field in sql
type string sql type
column string sql column name
auto_increment void recommend, if your table primary key have auto_increment attribute must add it
autoincrement void same as auto_increment
foreign key void to add foreign key feature when create table
alias string change field name with toyorm
join string to select related container field when call brick.Join

other custom TAG will append to end of CREATE TABLE field

Bind models

  1. model kind must be a struct or a point with struct

  2. the model is what information that toyorm know about the table

brick := toy.Model(&User{})
// or
brick := toy.Model(User{})
Sql Operation
create table
var err error
_, err = toy.Model(&User{}).Debug().CreateTable()
// CREATE TABLE user (id BIGINT AUTO_INCREMENT,created_at TIMESTAMP NULL,updated_at TIMESTAMP NULL,deleted_at TIMESTAMP NULL,name VARCHAR(255),age BIGINT ,sex VARCHAR(255) , PRIMARY KEY(id))
// CREATE INDEX idx_user_deletedat ON user(deleted_at)

// UPDATE user SET deleted_at=? WHERE name = ?, args:[]interface {}{(*time.Time)(0xc4200dbfa0), "bigpigeon"}
ToyBrick

use toy.Model will create a ToyBrick, you need use it to build grammar and operate the database

Where condition

affective update/find/delete operation

usage

where will clean old conditions and make new one

brick.Where(<expr>, <Key>, [value])

conditions will copy conditions and clean old conditions

brick.Conditions(<toyorm.Search>)

or & and condition will use or/and to link new condition when current condition is not nil

brick.Or().Condition(<expr>, <Key>, [value])
brick.And().Condition(<expr>, <Key>, [value])

or & and conditions will use or/and to link new conditions

brick.Or().Conditions(<toyorm.Search>)
brick.And().Conditions(<toyorm.Search>)
SearchExpr
SearchExpr to sql example
ExprAnd AND brick.Where(ExprAnd, Product{Name:"food one", Count: 4}) // WHERE name = "food one" AND Count = 4
ExprOr OR brick.Where(ExprOr, Product{Name:"food one", Count: 4}) // WHERE name = "food one" OR Count = "4"
ExprEqual = brick.Where(ExprEqual, OffsetOf(Product{}.Name), "food one") // WHERE name = "find one"
ExprNotEqual <> brick.Where(ExprNotEqual, OffsetOf(Product{}.Name), "food one") // WHERE name <> "find one"
ExprGreater > brick.Where(ExprGreater, OffsetOf(Product{}.Count), 3) // WHERE count > 3
ExprGreaterEqual >= brick.Where(ExprGreaterEqual, OffsetOf(Product{}.Count), 3) // WHERE count >= 3
ExprLess < brick.Where(ExprLess, OffsetOf(Product{}.Count), 3) // WHERE count < 3
ExprLessEqual <= brick.Where(ExprLessEqual, OffsetOf(Product{}.Count), 3) // WHERE count <= 3
ExprBetween Between brick.Where(ExprBetween, OffsetOf(Product{}.Count), [2]int{2,3}) // WHERE count BETWEEN 2 AND 3
ExprNotBetween NOT Between brick.Where(ExprNotBetween, OffsetOf(Product{}.Count), [2]int{2,3}) // WHERE count NOT BETWEEN 2 AND 3
ExprIn IN brick.Where(ExprIn, OffsetOf(Product{}.Count), []int{1, 2, 3}) // WHERE count IN (1,2,3)
ExprNotIn NOT IN brick.Where(ExprNotIn, OffsetOf(Product{}.Count), []int{1, 2, 3}) // WHERE count NOT IN (1,2,3)
ExprLike LIKE brick.Where(ExprLike, OffsetOf(Product{}.Name), "one") // WHERE name LIKE "one"
ExprNotLike NOT LIKE brick.Where(ExprNotLike, OffsetOf(Product{}.Name), "one") // WHERE name NOT LIKE "one"
ExprNull IS NULL brick.Where(ExprNull, OffsetOf(Product{}.DeletedAt)) // WHERE DeletedAt IS NULL
ExprNotNull IS NOT NULL brick.Where(ExprNotNull, OffsetOf(Product{}.DeletedAt)) // WHERE DeletedAt IS NOT NULL
example

single condition

brick = brick.Where(toyorm.ExprEqual, Offsetof(Product{}.Tag), "food")
or use string
brick = brick.Where("=", Offsetof(Product{}.Tag), "food")
// WHERE tag = "food"

combination condition

brick = brick.Where(toyorm.ExprEqual, Offsetof(Product{}.Count), 2).And().
    Condition(toyorm.ExprGreater, Offsetof(Product{}.Price), 3).Or().
    Condition(toyorm.ExprEqual, Offsetof(Product{}.Count), 4)
or use string
brick = brick.Where("=", Offsetof(Product{}.Count), 2).And().
    Condition(">", Offsetof(Product{}.Price), 3).Or().
    Condition("=", Offsetof(Product{}.Count), 4)
// WHERE count = 2 and price > 3 or count = 4

priority condition

brick.Where(toyorm.ExprGreater, Offsetof(Product{}.Price), 3).And().Conditions(
    brick.Where(toyorm.ExprEqual, Offsetof(Product{}.Count), 2).Or().
    Condition(toyorm.ExprEqual, Offsetof(Product{}.Count), 1).Search
)
or use string
brick.Where(">", Offsetof(Product{}.Price), 3).And().Conditions(
    brick.Where("=", Offsetof(Product{}.Count), 2).Or().
    Condition("=", Offsetof(Product{}.Count), 1).Search
)
// WHERE price > 3 and (count = 2 or count = 1)

brick.Conditions(
    brick.Where(toyorm.ExprEqual, Offsetof(Product{}.Count), 2).Or().
        Condition(toyorm.ExprEqual, Offsetof(Product{}.Count), 1).Search,
).And().Conditions(
    brick.Where(toyorm.ExprEqual, Offsetof(Product{}.Price), 3).Or().
        Condition(toyorm.ExprEqual, Offsetof(Product{}.Price), 4).Search,
)
or use string
brick.Conditions(
    brick.Where("=", Offsetof(Product{}.Count), 2).Or().
        Condition("=", Offsetof(Product{}.Count), 1).Search,
).And().Conditions(
    brick.Where("=", Offsetof(Product{}.Price), 3).Or().
        Condition("=", Offsetof(Product{}.Price), 4).Search,
)
// WHERE (count = ? OR count = ?) AND (price = ? OR price = ?)

limit & offset

brick := brick.Offset(2).Limit(2)
// LIMIT 2 OFFSET 2

order by

brick = brick.OrderBy(Offsetof(Product{}.Name))
// ORDER BY name

order by desc

brick = brick.OrderBy(brick.ToDesc(Offsetof(Product{}.Name)))
// ORDER BY name DESC
Transaction

start a transaction

brick = brick.Begin()

rollback all sql action

err = brick.Rollback()

commit all sql action

err = brick.Commit()
Debug

if Set debug all sql action will have log

brick = brick.Debug()
IgnoreMode

when I Update or Search with struct that have some zero value, did I update it ?

use IgnoreMode to differentiate what zero value should update

brick = brick.IgnoreMode(toyorm.Mode("Update"), toyorm.IgnoreZero ^ toyorm.IgnoreZeroLen)
// ignore all zeor value but excloud zero len slice
// now value = []int(nil) will ignore when update
// but value = []int{} will update when update

In default

Operation Mode affect
Insert IgnoreNo brick.Insert()
Replace IgnoreNo brick.Replace()
Condition IgnoreZero brick.Where(ExprAnd/ExprOr, )
Update IgnoreZero brick.Update()

All of IgnoreMode

mode effective
IgnoreFalse ignore field type is bool and value is false
IgnoreZeroInt ignore field type is int/uint/uintptr(incloud their 16,32,64 bit type) and value is 0
IgnoreZeroFloat ignore field type is float32/float64 and value is 0.0
IgnoreZeroComplex ignore field type is complex64/complex128 and value is 0 + 0i
IgnoreNilString ignore field type is string and value is ""
IgnoreNilPoint ignore field type is point/map/slice and value is nil
IgnoreZeroLen ignore field type is map/array/slice and len = 0
IgnoreNullStruct ignore field type is struct and value is zero value struct e.g type A struct{A string,B int}, A{"", 0} will be ignore
IgnoreNil ignore with IgnoreNilPoint and IgnoreZeroLen
IgnoreZero ignore all of the above
BindFields

if bind a not null fields, the IgnoreMode will failure

{
    var p Product
    result, err := brick.BindDefaultFields(Offsetof(p.Price), Offsetof(p.UpdatedAt)).Update(&Product{
        Price: 0,
    })
   // process error
   ...
}
var products []Product
result, err = brick.Find(&products)
// process error
...

for _, p := range products {
    fmt.Printf("product name %s, price %v\n", p.Name, p.Price)
}
Scope

use scope to do some custom operation

// desc all order by fields
brick.Scope(func(t *ToyBrick) *ToyBrick{

    newOrderBy := make([]*ModelFields, len(t.orderBy))
    for i, f := range t.orderBy {
        newOrderBy = append(newOrderBy, t.ToDesc(f))
    }
    newt := *t
    newt.orderBy = newOrderBy
    return &newt
})
Template

use template exec to replace default exec

now template only support Insert/Save/Update/Find

Custom insert
data := Product{
    Name:  "bag",
    Price: 9999,
    Count: 2,
    Tag:   "container",
}
result, err := brick.Template("INSERT INTO $ModelName($Columns) Values($Values)").Insert(&data)
// INSERT INTO product(created_at,updated_at,deleted_at,name,price,count,tag) Values(?,?,?,?,?,?,?) args:["2018-04-01T17:05:48.927499+08:00","2018-04-01T17:05:48.927499+08:00",null,"bag",9999,2,"container"]
Custom find
var data Product
// if driver is mysql use "USE INDEX" replace "INDEXED BY"
result, err := brick.Template("SELECT $Columns FROM $ModelName INDEXED BY idx_product_name $Conditions").
    Where("=", Offsetof(Product{}.Name), "bag").Find(&data)
// SELECT id,created_at,updated_at,deleted_at,name,price,count,tag FROM product INDEXED BY idx_product_name  WHERE deleted_at IS NULL AND name = ? LIMIT 1  args:["bag"]
Custom update

set count = count + 2

result, err := brick.Template(fmt.Sprintf("UPDATE $ModelName SET $Values,$FN-Count = $0x%x + ? $Conditions", Offsetof(Product{}.Count)), 2).
	Where("=", Offsetof(Product{}.Name), "bag").Update(&Product{Price: 200})
// UPDATE product SET updated_at = ?,price = ?,count = count + ?  WHERE deleted_at IS NULL AND name = ?  args:["2018-04-01T17:50:35.205377+08:00",200,2,"bag"]
Placeholder

follower placeholder use in template example

two special placeholder

  1. $FN- will convert struct field name to table field name e.g $FN-Name => name
  2. $0x will convert struct field offset to table field name e.g $0x58 => Count
action \ placeholder $ModelName $Columns $Values $Conditions
Find product id,data,... - WHERE ... ORDER BY ... GROUP BY ... LIMIT ... OFFSET ...
Insert product id,data,... ?,?,... WHERE ... ORDER BY ... GROUP BY ... LIMIT ... OFFSET ...
Save product id,data,... ?,?,... WHERE ... ORDER BY ... GROUP BY ... LIMIT ... OFFSET ...
Update product id,data,... id = ?,data = ?,... WHERE ... ORDER BY ... GROUP BY ... LIMIT ... OFFSET ...
Thread safe

Thread safe if you comply with the following agreement

  1. make sure ToyBrick object is read only, if you want to change it, create a new one

  2. do not use append to change ToyBrick's slice data,use make and copy to clone new slice

Preload

preload need have relation field and container field

relations field is used to link the main record and sub record

container field is used to hold sub record

Preload example

here

One to one

relation field at sub model

relation field name must be main model type name + main model primary key name

type User struct {
    toyorm.ModelDefault
    // container field
    Detail  *UserDetail
}

type UserDetail struct {
    ID       int    `toyorm:"primary key;auto_increment"`
    // relation field
    UserID   uint   `toyorm:"index"`
    MainPage string `toyorm:"type:Text"`
}

// load preload
brick = toy.Model(&User{}).Debug().Preload(OffsetOf(User.Detail)).Enter()
Belong to

relation field at main model

relation field name must be container field name + sub model primary key name

type User struct {
    toyorm.ModelDefault
    // container field
    Detail   *UserDetail
    // relation field
    DetailID int `toyorm:"index"`
}

type UserDetail struct {
    ID       int    `toyorm:"primary key;auto_increment"`
    MainPage string `toyorm:"type:Text"`
}
One to many

relation field at sub model

relation field name must be main model type name + main model primary key name

type User struct {
    toyorm.ModelDefault
    // container field
    Blog    []Blog
}

type Blog struct {
    toyorm.ModelDefault
    // relation field
    UserID  uint   `toyorm:"index"`
    Title   string `toyorm:"index"`
    Content string
}
Many to many

many to many not need to specified the relation ship,it relation field at middle model

type User struct {
    toyorm.ModelDefault
    // container field
    Friends    []*User
}
Load preload

when you finish model definition, it time to load preload

// create a main brick
brick = toy.Model(&User{})
// create a sub brick
subBrick := brick.Preload(OffsetOf(User.Blog))
// you can editing any attribute what you want, just like editing it on main model
subBrick = subBrick.Where(ExprEqual, OffsetOf(Blog.Title), "my blog")
// finished change ,use Enter() go back the main brick
brick = subBrick.Enter()

if you not like relation field name rule,use custom module to create it

// one to one custom
brick.CustomOneToOnePreload(<main container>, <sub relation>, [sub model struct])
// belong to custom
brick.CustomBelongToPreload(<main container>, <main relation>, [sub model struct])
// one to many
brick.CustomOneToManyPreload(<main container>, <sub relation>, [sub model struct])
// many to many
brick.CustomManyToManyPreload(<middle model struct>, <main container>, <main relation>, <sub relation>, [sub model struct])
Join

different association query is join query

Example

here

Model Define

use join tag to association related field/ join tag value must same as container field name

type Extra map[string]interface{}

func (e *Extra) Scan(value interface{}) error {
	switch v := value.(type) {
	case string:
		return json.Unmarshal([]byte(v), e)
	case []byte:
		return json.Unmarshal(v, e)
	default:
		return errors.New("not support type")
	}
}

func (e Extra) Value() (driver.Value, error) {
	return json.Marshal(e)
}

type Color struct {
	Name string `toyorm:"primary key;join:ColorDetail"`
	Code int32
}

type Comment struct {
	toyorm.ModelDefault
	ProductDetailProductID uint32 `toyorm:"index"`
	Data                   string `toyorm:"type:VARCHAR(1024)"`
}

type ProductDetail struct {
	ProductID  uint32 `toyorm:"primary key;join:Detail"`
	Title      string
	CustomPage string `toyorm:"type:text"`
	Extra      Extra  `toyorm:"type:VARCHAR(2048)"`
	Color      string `toyorm:"join:ColorDetail"`
	ColorJoin  Color  `toyorm:"alias:ColorDetail"`
	Comment    []Comment
}

type Product struct {
	ID        uint32     `toyorm:"primary key;auto_increment;join:Detail"`
	CreatedAt time.Time  `toyorm:"NULL"`
	DeletedAt *time.Time `toyorm:"NULL"`
	Name      string
	Count     int
	Price     float64
	Detail    *ProductDetail
}
Join in Find

Swap on Join just like Enter on Preload, can back to previous data

brick := toy.Model(&tab).Debug().
    Join(Offsetof(tab.Detail)).
    Join(Offsetof(detailTab.ColorJoin)).Swap().Swap()
var scanData []Product
result, err = brick.Find(&scanData)
// SELECT m.id,m.created_at,m.deleted_at,m.name,m.count,m.price,m_0.product_id,m_0.title,m_0.custom_page,m_0.extra,m_0.color,m_0_0.name,m_0_0.code FROM `product` as `m` JOIN `product_detail` AS `m_0` ON m.id = m_0.product_id JOIN `color` AS `m_0_0` ON m_0.color = m_0_0.name   WHERE m.deleted_at IS NULL

use Join to switch current model and add conditions

// where Product.Name = "clean stick" or Color.Name = "black"
brick := toy.Model(&tab).Debug().Where("=", Offsetof(tab.Name), "clean stick").
    Join(Offsetof(tab.Detail)).
    Join(Offsetof(detailTab.ColorJoin)).Or().Condition("=", Offsetof(colorTab.Name), "black").
    Swap().Swap()
var scanData []Product
result, err = brick.Find(&scanData)
// SELECT m.id,m.created_at,m.deleted_at,m.name,m.count,m.price,m_0.product_id,m_0.title,m_0.custom_page,m_0.extra,m_0.color,m_0_0.name,m_0_0.code FROM `product` as `m` JOIN `product_detail` AS `m_0` ON m.id = m_0.product_id JOIN `color` AS `m_0_0` ON m_0.color = m_0_0.name   WHERE m.deleted_at IS NULL AND (m.name = ? OR m_0_0.name = ?)  args:["clean stick","black"]

set order just like add conditions

// where Product.Name = "clean stick" or Color.Name = "black"
brick := toy.Model(&tab).Debug().
    Join(Offsetof(tab.Detail)).
    Join(Offsetof(detailTab.ColorJoin)).OrderBy(Offsetof(colorTab.Name)).
    Swap().Swap()

also can set GroupBy but here not example

Preload On Join

Preload method also work on Join mode

brick := toy.Model(&tab).Debug().
    Join(Offsetof(tab.Detail)).Preload(Offsetof(detailTab.Comment)).Enter().
    Join(Offsetof(detailTab.ColorJoin)).Swap().Swap()
var scanData []Product

Selector

toyorm support following selector

operation \ selector OffsetOf Name string map[OffsetOf]interface{} map[string]interface{} struct
Update no no yes yes yes
Insert no no yes yes yes
Save no no yes yes yes
Where & Conditions yes yes yes yes yes
BindFields yes yes no no no
Preload & Custom Preload yes yes no no no
OrderBy yes yes no no no
Find no no no no yes

Collection

collection provide multiple database operation

ToyCollection

ToyCollection is basic of the collection , it like Toy

toyCollection, err = toyorm.OpenCollection("sqlite3", []string{"", ""}...)
CollectionBrick

CollectionBrick use to build grammar and operate the database, like ToyBrick

brick := toyCollection.Model(&User{})
Selector

Selector use to select database when Insert/Save

CollectionBrick has default selector dbPrimaryKeySelector

you can custom db selector

func idSelector(n int, keys ...interface{}) int {
	sum := 0
	for _, k := range keys {
		switch val := k.(type) {
		case int:
			sum += val
		case int32:
			sum += int(val)
		case uint:
			sum += int(val)
		case uint32:
			sum += int(val)
		default:
			panic("primary key type not match")
		}
	}
	return sum % n
}

brick = brick.Selector(idSelector)
id generator

in this mode,Field tag auto_increment was invalid

you need create id generator

// a context id generator
type IDGenerator map[*toyorm.Model]chan int

func (g IDGenerator) CollectionIDGenerate(ctx *toyorm.CollectionContext) error {
	if g[ctx.Brick.Model] == nil {
		idGenerate := make(chan int)
		go func() {
			current := 1
			for {
				// if have redis, use redis-cli
				idGenerate <- current
				current++
			}

		}()
		g[ctx.Brick.Model] = idGenerate
	}
	primaryKey := ctx.Brick.Model.GetOnePrimary()
	for _, record := range ctx.Result.Records.GetRecords() {
		if field := record.Field(primaryKey.Name()); field.IsValid() == false || toyorm.IsZero(field) {
			v := <-g[ctx.Brick.Model]
			record.SetField(primaryKey.Name(), reflect.ValueOf(v))
		}
	}
	return nil

}

// set id genetor to model context
toy.SetModelHandlers("Save", brick.Model, toyorm.CollectionHandlersChain{idGenerate.CollectionIDGenerate})
// set id genetor to all preload models context
for _, pBrick := range brick.MapPreloadBrick {
		toy.SetModelHandlers("Save", pBrick.Model, toyorm.CollectionHandlersChain{idGenerate.CollectionIDGenerate})
}
sql action

toy collection sql action is same as Toy

insert

users := []User{
    {Name: "Turing"},
    {Name: "Shannon"},
    {Name: "Ritchie"},
    {Name: "Jobs"},
}
result, err = userBrick.Insert(&users)
// error process

// view report log
fmt.Printf("report:\n%s", result.Report())

find

var jobs User
result, err = userBrick.Where(toyorm.ExprEqual, Offsetof(User{}.Name), "Jobs").Find(&jobs)
// error process

// view report log
fmt.Printf("report:\n%s", result.Report())

delete

result, err = userBrick.Delete(&jobs)
// error process

// view report log
fmt.Printf("delete report:\n%s\n", result.Report())
