Functions

func AddBatchDeleteBeforeAndAfterHookPoints 

func AddBatchDeleteBeforeAndAfterHookPoints(typeString string,
	before func(ms []IModel, db *gorm.DB, oid *datatypes.UUID, typeString string, cargo *BatchHookCargo) error,

AddBatchDeleteBeforeAndAfterHookPoints adds hookpoints which are called before and after batch delete. Either one can be left as nil

func AddBatchUpdateBeforeAndAfterHookPoints 

func AddBatchUpdateBeforeAndAfterHookPoints(typeString string,
	before func(ms []IModel, db *gorm.DB, oid *datatypes.UUID, typeString string, cargo *BatchHookCargo) error,
	after func(ms []IModel, db *gorm.DB, oid *datatypes.UUID, typeString string, cargo *BatchHookCargo) error)

AddBatchUpdateBeforeAndAfterHookPoints adds hookpoints which are called before and after batch update. Either one can be left as nil

func AddModelRegistry 

func AddModelRegistry(typeString string, typ reflect.Type)

AddModelRegistry adds a New function for an IModel

func AddOwnerToModelRegistry added in v0.1.8 

func AddOwnerToModelRegistry(typeString string, typ reflect.Type)

AddOwnerToModelRegistry adds a New function for an owner

func AddUserToModelRegistry added in v0.1.3 

func AddUserToModelRegistry(typeString string, typ reflect.Type)

AddUserToModelRegistry adds a New function for a user

func RegisterOwnershipModel added in v0.1.3

Types

type BaseModel 

type BaseModel struct {
	ID        *datatypes.UUID `gorm:"type:binary(16);primary_key;" json:"id"`
	CreatedAt time.Time       `sql:"index" json:"createdAt"`
	UpdatedAt time.Time
	DeletedAt *time.Time `sql:"index"`
}

BaseModel is the base class domain model which has standard ID

func (*BaseModel) BeforeCreate 

func (b *BaseModel) BeforeCreate(scope *gorm.Scope) error

BeforeCreate sets a UUID if no ID is set (this is Gorm's hookpoint)

func (*BaseModel) GetID 

func (b *BaseModel) GetID() *datatypes.UUID

GetID Get the ID field of the model (useful when using interface)

func (*BaseModel) SetID 

func (b *BaseModel) SetID(id *datatypes.UUID)

SetID Set the ID field of the model (useful when using interface)

func (*BaseModel) Validate 

func (b *BaseModel) Validate() error

Validate validates the model

type BatchHookCargo 

type BatchHookCargo struct {
	Payload interface{}
}

BatchHookCargo is payload between batch update and batch delete hookpoints

type Client 

type Client struct {
	gorm.Model  // Includes ID, CreatedAt, UpdatedAt, DeletedAt
	Name        string
	Secret      string `gorm:"not null" json:"-"`
	RedirectURI string // TODO: RedirectURI can be multiples
}

Client is the program that makes request to the API So iOS would be one client, android would be another Any website making API request would have its own client ID This needs to be inserted into db beforehand. So we can validate the app making the request. Any such app has the permission to create the user
