ruby-on-rails - 迁移失败无法引用哈希值

Question

Rails 5.2 至 6 升级

    create_table :logs, id: :uuid do |t|
      t.uuid :trackable_id, null: false
      t.string :trackable_type, null: false
      t.uuid :owner_id, null: false
      t.string :owner_type, null: false
      t.string :key, null: false
      t.hstore :parameters, null: false, default: {}
      t.datetime :created_at
    end

但是迁移失败说

rails aborted!
StandardError: An error has occurred, this and all later migrations canceled:

can't quote Hash

这个补丁是什么

Answer 1

尝试用引号将空散列括起来:

t.hstore :parameters, null: false, default: "{}"
