ent/ent v0.9.0

on GitHub

We are excited to share the v0.9.0 release! 🎊

This release contains several bug fixes and many small features and improvements to the ent/schema, ent runtime, and ent-codegen. Also, 2 major features were added to the framework, Upsert/UpsertBulk APIs, and Row-level locking (see details below). See examples:

// Upsert one.
id, err := client.User.
    Create().
    SetAge(30).
    SetName("Ariel").
    OnConflict().
    SetName("Mashraki").
    ID(ctx)

// Upsert bulk.
err := client.User. 
    CreateBulk(builders...). 
    OnConflict(). 
    UpdateNewValues().
    Exec(ctx)

// Row-level locking.
tx.User.Query().
    Where(user.Name(name)).
    ForUpdate().
    Only(ctx)

In the next release, we'll introduce the new migration framework for SQL.
