PgSearch 1.0.0在试图从控制台重建时抛出ModelNotMultisearchable错误

Question

我有一个应用程序有4个不同的模型，它们是多区段的，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} 
       } 

正如你可以看到在一个点上，我试图设置这种多分配方式。

最近我们知道应该返回的项目不在搜索结果中，我想我必须重建pg_search_documents;然而那的投掷一个错误：

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/vendor/bundle/ruby/2.0.0/gems/pg_search-0.7.3/lib/pg_search/multisearch.rb:10:in `new'

    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作为pg_search_scope的，所以设置一类如以上所述multisearch：multisearchable：针对=> [：标题，：描述] - 但即使如此，我得到重建问题。

我试图从pg_search表中删除和重建，但即使这是引发错误的手工方式：

我已经得到了同样的错误，而试图重建（首次，安装）通过Rails命令行与PgSearch::Multisearch.rebuild(Professor)。什么工作对我来说是不是从使用the alternative approach命令行重建建议在Github上：

rake pg_search:multisearch:rebuild[Professor]

这似乎为我工作 - 它不抛出一个错误，当我去到了Rails控制台并运行PgSearch.multisearch("query")它返回一个结果，而在它返回一个错误之前。

我知道这不是一个修复，但它是解决眼前的问题。我希望它有帮助 - 在他们的Github上发布一个问题可能会导致更全面的修复。
