Is there a way to pull records from activerecord in a hash already indexed by id instead of an array? This is what im currently doing:
results = {} Table.select { |current| results[current.id] = current } Im assuming that there has to be a method that does that?

ActiveRecord::Base indicates that the ActiveRecord class or module has a static inner class called Base that you're extending. Edit: as Mike points out, in this case ActiveRecord is a module...
ActiveRecord expects applications to follow certain naming conventions. These conventions extend from file naming, class naming, table naming and more. By default classes are singular, tables are plural, primary keys are id and foreign keys are table_id.
The active record pattern is an approach to accessing data in a database. A database table or view is wrapped into a class. Thus, an object instance is tied to a single row in the table. After creation of an object, a new row is added to the table upon save.
Rails Active Records provide an interface and binding between the tables in a relational database and the Ruby program code that manipulates database records. Ruby method names are automatically generated from the field names of database tables.
Table.all.index_by { |t| t.id } Or:
Table.all.index_by(&:id) if you're into the whole brevity thing.
