尝试从控制台重建时,PgSearch 1.0.0抛出ModelNotMultisearchable错误

标签: ruby-on-rails database pg-search

我有一个带有4种不同模型的应用程序,这些模型是多种可用的,但它们最初是用pg_search_scope设置的;即:

class Episode < ActiveRecord::Base
  include PgSearch
  # multisearchable :against => [:title, :description]

  pg_search_scope :search_text,
    :against => [:title, :description],
    :using => {
               :tsearch => {:prefix => true}
              }

正如您所看到的那样,我尝试以多种方式设置它。

最近我们知道应该返回的项目不在搜索结果中,我认为我必须重建pg_search_documents;然而,这是一个错误:

irb(main):004:0> PgSearch::Multisearch.rebuild(Show)
PgSearch::Multisearch::ModelNotMultisearchable: PgSearch::Multisearch::ModelNotMultisearchable
    from /app/vendor/bundle/ruby/2.0.0/gems/pg_search-0.7.3/lib/pg_search/multisearch/rebuilder.rb:6:in `initialize'

    from /app/bin/rails:4:in `require'
    from /app/bin/rails:4:in `<main>'
irb(main):005:0> 

我认为这可能是因为设置为pg_search_scope,所以我使用multisearch设置了一个类:multisearchable:against =&gt; [:title,:description] - 但即使这样,我也会遇到重建问题。

我尝试了从pg_search表中删除的手动方式并进行了重建,但即使这样做也会引发错误:

尝试通过带有PgSearch::Multisearch.rebuild(Professor)的Rails命令行重建(第一次安装)时,我遇到了同样的错误。对我来说有用的是使用Github上推荐的the alternative approach从命令行重建:

rake pg_search:multisearch:rebuild[Professor]

这似乎对我有用 - 它不会抛出错误,当我转到Rails控制台并运行PgSearch.multisearch("query")后,它返回一个结果,而在它返回错误之前。

我知道这不是一个解决方案,但它是解决当前问题的解决方案。我希望它有所帮助 - 在他们的Github上发布一个问题可能会导致更全面的修复。
