Instance Method Summary

• #as(alias_name, quote: true) ⇒ Object
• #asc ⇒ Object
• #desc ⇒ Object
• #to_arel(table, model) ⇒ Object

  The model travels with the table because some SQL cannot be written without knowing the adapter, and a node is built before anything knows which one it will be rendered for -- a symbol becomes a node inside a refinement, where there is no model to ask.

#to_arel(table, model) ⇒ Object

The model travels with the table because some SQL cannot be written without knowing the adapter, and a node is built before anything knows which one it will be rendered for -- a symbol becomes a node inside a refinement, where there is no model to ask. Most nodes never look at it and only pass it on.

Raises:

  raise ScriptError, "subclass must override this method"
