phoenix_postgres_pub_sub v0.1.1 mix phoenix_postgres_pub_sub.gen.channel

Generates a migration to listen to changes in postgres. The repository must be set under :ecto_repos in the current app configuration or given via the -r option.

Examples

mix ecto.gen.migration listen_to_member_changes --table=members
mix ecto.gen.migration listen_to_member_changes --table=members --repo=Custom.Repo

The generated migration filename will be prefixed with the current timestamp in UTC which is used for versioning and ordering. By default, the migration will be generated to the “priv/YOUR_REPO/migrations” directory of the current application but it can be configured to be any subdirectory of priv by specifying the :priv key under the repository configuration. This generator will automatically open the generated file if you have ECTO_EDITOR set in your environment variable.

Command line options

  • -r, --repo - the repo to generate migration for
  • -t, --table - the table to listen the notifications migration for
