Defined in:

Overview

Extracts ActiveRecord model metadata using a hybrid approach:

  • Rails reflection for runtime data (associations, validations, enums, table info)
  • Prism AST for source-level declarations (scopes, callbacks, macros, methods)

The AST layer replaces all regex/scan/match? source parsing with Prism::Dispatcher-based single-pass extraction via SourceIntrospector.

  # A hybrid app (ActiveRecord primary, Mongoid gem present too) has
  # documents that AR reflection can never see - they don't descend
  # from ActiveRecord::Base. Supplement rather than replace, so a
  # pure-AR model in a hybrid app keeps its full reflection-based
  # details instead of being reduced to Mongoid's blanket static pass.
  if RailsAiContext::AppKind.mongoid?(app.root)
    mongoid_static_models.each do |class_name, details|

#static_call ⇒ Object

Static tier: models are discovered by globbing every model directory PathResolver resolves (conventional app/models, packs, engines, and configured extras) and parsed with the source listeners; nothing is constantized. The table name is inferred from the class name (Rails convention), which is why every entry is tagged STATIC rather than VERIFIED - custom table_name= calls surface in :macros but are not resolved. When the same class name is found in more than one directory, the first discovery wins.
