Module: Hecks::Forms::RecordTable

Defined in:
lib/hecks/forms/record_table.rb

Overview

An array of Record (or anything answering #id/#state — a Runtime::Instance qualifies without wrapping) -> an HTML table. Shared by the aggregate index page (record_renderer.rb) and a query's own results (query_form_renderer.rb) — the same records read the same columns either way.

def self.cell(instance, name)
  # `state` holds `Runtime::Value` wherever an attribute is a value
  # object, not a plain Hash — `.materialize` is the runtime's own
  # unwrap (value.rb), the same one a `to_h` read anywhere else in
  # this codebase goes through, so a table cell agrees with every
  # other reader about what a stored field actually contains.
  value = Runtime::Value.materialize(instance.state[name])
  case value
  when Hash then value.values.first
  when nil then ""
  else value
