Tane

Tane means seeds.

# priv/repo/seeds.exs

use Tane

repo(MyApp.Repo)
|> model(MyApp.User)
|> seed(name: "Bob",  email: "bob@black.com")
|> seed(name: "Mary", email: "mary@blue.com")

Then do this.

$ mix tane

You can specify the path.

$ mix tane --path priv/another_repo/seeds.exs

If you want to delete all data before seeding, delete_all!/1 is useful.

repo(MyApp.Repo)
|> model(MyApp.User)  # have to register these two before delete_all!.
|> delete_all!
|> seed(name: "Bob", email: "bob@black.com")

Use get_by/2 to get saved models.

use Tane

alias MyApp.User
alias MyApp.Post
alias MyApp.Repo

repo(Repo)
|> model(User)
|> seed(name: "bob")
|> seed(name: "mary")
|> model(Post)
|> seed(title: "Hello", body: "I'm bob", user_id: get_by(User, name: "bob").id)
