phx_gen_auth v0.7.0 mix phx.gen.auth View Source

Generates authentication logic for a resource.

mix phx.gen.auth Accounts User users

The first argument is the context module followed by the schema module and its plural name (used as the schema table name).

For more information about the generated authentication system, see the Overview.

Password hashing

The password hashing mechanism defaults to bcrypt for Unix systems and pbkdf2 for Windows systems. Both systems use the Comeonin interface.

The password hashing mechanism can be overriden with the --hashing-lib option. The following values are supported:

bcrypt - bcrypt_elixir
pbkdf2 - pbkdf2_elixir
argon2 - argon2_elixir

For more information about choosing these libraries, see the Comeonin project.

Web namespace

By default, the controllers and view will be namespaced by the schema name. You can customize the web module namespace by passing the --web flag with a module name, for example:

mix phx.gen.auth Accounts User users --web Warehouse

Which would generate the controllers, views, templates and associated tests in nested in the MyAppWeb.Warehouse namespace:

lib/my_app_web/controllers/warehouse/user_auth.ex
lib/my_app_web/controllers/warehouse/user_confirmation_controller.ex
lib/my_app_web/views/warehouse/user_confirmation_view.ex
lib/my_app_web/templates/warehouse/user_confirmation/new.html.eex
test/my_app_web/controllers/warehouse/user_auth_test.exs
test/my_app_web/controllers/warehouse/user_confirmation_controller_test.exs
and so on...

Binary ids

The --binary-id option causes the generated migration to use binary_id for its primary key and foreign keys.

Default options

This generator uses default options provided in the :generators configuration of your application. These are the defaults:

config :your_app, :generators,
  binary_id: false,
  sample_binary_id: "11111111-1111-1111-1111-111111111111"

You can override those options per invocation by providing corresponding switches, e.g. --no-binary-id to use normal ids despite the default configuration.

Custom table names

By default, the table name for the migration and schema will be the plural name provided for the resource. To customize this value, a --table option may be provided. For example:

mix phx.gen.auth Accounts User users --table accounts_users

This will cause the generated tables to be named "accounts_users" and "accounts_users_tokens".
