A simple wrapper around sql.DB to help with structs. Not quite an ORM.
Philosophy: Don't make an ORM
Example:
// Setup
require "modeldb"
db := ...
modeldb.SetDB(db)
// Declaring a model
type User struct {
Id string `json:"id" db:"id,autoinc"`
Email string `json:"email" db:"email,null"`
Scrypt []byte `json:"-" db:"scrypt"`
Salt []byte `json:"-" db:"salt"`
}
var UserModel = db.GetModelInfo(new(User))
// Inserting a model
user := &User{Email:email, Scrypt:scrypt, Salt:salt}
_, err = modeldb.Exec(
`INSERT INTO user (`+UserModel.InsertFields+`)
VALUES (`+UserModel.Placeholders+`)`,
user,
)
// Querying a model
var user User
err := modeldb.QueryRow(
`SELECT `+UserModel.QueryFields+`
FROM user WHERE email=?`,
email,
).Scan(&user)
// Querying many rows
rows, err := modeldb.QueryAll(User{},
`SELECT `+UserModel.QueryFields+`
FROM user WHERE id < 100`)
)
if err != nil { panic(err) }
users := rows.([]*User)
// Auto-retry transaction blocks
err := db.DoBeginSerializable(func(tx *db.ModelTx) {
_, err := tx.Exec(...)
if err != nil {
panic(err)
}
...
})Also supports MySQL with some included helpers.
