Rihanna v1.2.2 Rihanna.Migration.Upgrade View Source
A set of tools for upgrading an existing Rihanna jobs table.
Rihanna stores jobs in a table in your database. The default table name is
“rihanna_jobs”. The name is configurable by either passing it as an argument
to the functions below or setting :jobs_table_name
in Rihanna’s config.
Using Ecto
The easiest way to upgrade the database is with Ecto.
Run mix ecto.gen.migration upgrade_rihanna_jobs
and make your migration look
like this:
defmodule MyApp.UpgradeRihannaJobs do
use Rihanna.Migration.Upgrade
end
Now you can run mix ecto.migrate
.
Without Ecto
Ecto is not required to run Rihanna. If you want to upgrade the table yourself,
without Ecto, take a look at either statements/0
or sql/0
.
