Rails - 4.2.1 undefined method `or 'for # <ActiveRecord :: Relation []>

Я пытаюсь использовать оператор or с помощью @verses, но по какой-то причине я продолжаю получать ошибку отношения activerecord.Rails - 4.2.1 undefined method `or 'for # <ActiveRecord :: Relation []>

searches_controller.rb

class SearchesController < ApplicationController 
    def search 
    @verses = Verse.where("LOWER(verse) LIKE LOWER(?)", params[:search_term]).or.where("LOWER(verse) LIKE LOWER(?)", "%#{params[:search_term]}%") 
    @books = Book.where("LOWER(book_name) LIKE LOWER(?)", "%" + params[:search_term] + "%") 
    @versions = Version.where("LOWER(name) LIKE LOWER(?)", "%" + params[:search_term] + "%") 
    @results = @verses.paginate(:page => params[:page]) 
    # @json = @results.map { |item| {name: item.name, link: url_for(item)} } 
    respond_to do |format| 
     format.html 
     # format.json { render json: @json } 
    end 
    end 
end

Ошибка приложения показывает, что это

app/controllers/searches_controller.rb:3:in `search'

Что заставляет меня думать, что использование .Или в @verses

я даже не слышал, что рельсы были 'or' метод – JustMichael

если у вас длинные запросы, я бы сказал, что это хорошая идея создать класс для него – JustMichael

Насколько я знаю, эта функция была объединена с ведущей веткой rails, но еще не выпущена. – BroiSatse

Вы можете уменьшить длинные запросы контроллера, создав Scope.

в модели

scope :find_verse, ->(search_term) { where("LOWER(verse) LIKE LOWER (?) OR LOWER(verse) LIKE LOWER(%#{search_term}%)", search_term) }

В контроллере

@verses = Verse.find_verse(params[:search_term])

Спасибо, у вас новая ошибка, так что прогресс. – nadermx

Какую ошибку вы сейчас получаете? –

'ActiveRecord :: RecordNotFound in SearchesController # search' Не удалось найти версию без ID, но я думаю, что это не связано с этой конкретной проблемой. – nadermx

Rails - 4.2.1 undefined method `or 'for # <ActiveRecord :: Relation []>
