postgresql - Rails activeRecord version for to_tsvector() function of Postgresql

Question

I have a TSVECTOR column in my database and I want to update this column via Rails callback rather than a trigger. I want to know if there's an ActiveRecord code to achieve this. So far I'm doing this by manually executing a raw SQL and it doesn't look nice.

ActiveRecord::Base.connection.execute("update my_table set tsvector_document = to_tsvector('english', #{string_tokens}) where id = #{id}")

I'm wondering if there's a better approach to do this without using a raw SQL.

Thanks in advance.

我最终使用 rails 的 PG Search 插件来处理这个 TS Vector 转换。

PgSearch.multisearch_options = {
  using: {
    tsearch: {
      prefix: true,
      dictionary: 'english',
      tsvector_column: 'vector_column_name_here'
    },
    trigram: {
      threshold: 0.2
    }
  }
}
