Instance Method Details

#[](column_name) ⇒ Arel::Attributes::Attribute

Model[:column] shortcut for Model.arel_table[:column].

Written as an explicit method rather than delegate :[], to: :arel_table
because YARD's DSL handler crashes on delegate with an operator name.

column_name (Symbol or String) is the column to expose as an Arel
attribute. Aliased columns work because arel_table resolves them.

Returns:

• (Arel::Attributes::Attribute) —

  the attribute node, ready to
  chain Arel predicates (.eq, .gt, .in, .matches, .lower,
  .or, etc.) against.
