Provides runtime detection of the database adapter for Sequel configuration. This module dynamically detects the ActiveRecord adapter and returns the corresponding Sequel adapter, allowing users to change their database without needing to regenerate rodauth files.

Constant Summary collapse

SEQUEL_ADAPTERS =

Maps ActiveRecord adapter names to their corresponding Sequel adapter names. JRuby uses JDBC adapters which have different naming conventions.

{
  "postgresql" => (RUBY_ENGINE == "jruby") ? "postgresql" : "postgres",
  "mysql2" => (RUBY_ENGINE == "jruby") ? "mysql" : "mysql2",
  "sqlite3" => "sqlite",
  "oracle_enhanced" => "oracle",
  "sqlserver" => (RUBY_ENGINE == "jruby") ? "mssql" : "tinytds"

      Sequel.connect("jdbc:#{adapter}://", extensions: :activerecord_connection, keep_reference: false)

          "Please ensure your database configuration is correct and the required " \
          "database gems are installed. Original error: #{e.message}"
  end
end

.sequel_adapter ⇒ String

Returns the Sequel adapter name based on the current ActiveRecord adapter. If the ActiveRecord adapter is not in the SEQUEL_ADAPTERS mapping, the ActiveRecord adapter name is returned as-is, which may work for adapters where the names match between ActiveRecord and Sequel.

Returns:

  • (String) —

    the Sequel adapter name
