#as_description_list(obj, columns, opts = {}) ⇒ Object

as_description_list() prints a a two column table containing the name and value of a list of descriptions Usage: print_description_list([:id, :name, :status], my_instance, {})

Parameters:

  • columns —
    • Hash or Array or Hashes

      list of column definitions, A column defintion can be a String, Symbol, Hash or Proc

  • obj (Object) —

    an object to extract the data from, it is treated like a Hash.

  • opts (Map) (defaults to: {}) —

    rendering options for label :justify, :wrap

#build_column_definitions(*columns) ⇒ Array of OpenStruct

build_column_definitions constructs an Array of column definitions (OpenStruct) Each column is defined by a label (String), and a display_method (Proc)

Usage:

build_column_definitions(:id, :name)
build_column_definitions({"Object Id" => 'id'}, :name)
build_column_definitions({"ID" => 'id'}, "name", "plan.name", {status: lambda {|data| data['status'].upcase } })

Returns:

  • (Array of OpenStruct) —

    list of column definitions (OpenStruct) like:

    “ID”, display_method: ‘id’, “Name”, display_method: Proc
