ThinkingSphinx使用ActiveRecord 5.1.3索引失败

我最近将我的应用程序升级到Rails 5,现在当我想要索引时出现了一个错误(见下面的stacktrace)。

indexes categories(:slug), as: :category_slugs, facet: true
has categories(:id), as: :category_ids, facet: true

join_association.rb ( on github )文件并意识到 Category 对象存在,而不是 Relation

摘录:

def join_constraints(foreign_table, foreign_klass, join_type, tables, chain)
  joins         = []
  binds         = []
  tables        = tables.reverse

  # The chain starts with the target table, but we want to end with it here (makes
  # more sense in this context), so we reverse
  chain.reverse_each do |reflection|
    table = tables.shift
    klass = reflection.klass

    join_keys   = reflection.join_keys
    key         = join_keys.key
    foreign_key = join_keys.foreign_key

    constraint = build_constraint(klass, table, key, foreign_table, foreign_key)

    predicate_builder = PredicateBuilder.new(TableMetadata.new(klass, table))
    scope_chain_items = reflection.join_scopes(table, predicate_builder)
    klass_scope       = reflection.klass_join_scope(table, predicate_builder)

    scope_chain_items.concat [klass_scope].compact

    rel = scope_chain_items.inject(scope_chain_items.shift) do |left, right|
      left.merge right
      ############################ CRASH ############################
    end

    if rel && !rel.arel.constraints.empty?
      binds += rel.bound_attributes
      constraint = constraint.and rel.arel.constraints
    end

    if reflection.type
      value = foreign_klass.base_class.name
      column = klass.columns_hash[reflection.type.to_s]

      binds << Relation::QueryAttribute.new(column.name, value, klass.type_for_attribute(column.name))
      constraint = constraint.and klass.arel_attribute(reflection.type, table).eq(Arel::Nodes::BindParam.new)
    end

    joins << table.create_join(table, table.create_on(constraint), join_type)

    # The current table in this iteration becomes the foreign table in the next
    foreign_table, foreign_klass = table, klass
  end

  JoinInformation.new joins, binds
end

我的索引

# app/indices/programme_index.rb 
ThinkingSphinx::Index.define :programme, with: :active_record, delta: true do

  has id, as: :programme_id

  # Sphinx fields
  indexes website
  indexes admin_contact

  indexes categories(:slug), as: :category_slugs, facet: true
  has categories(:id), as: :category_ids, facet: true

end

# config/thinking_sphinx.yml
development:
  enable_star: true
  match_mode: boolean

生成的索引

如果我注释掉这两行,我会得到以下索引:
