Question

使用：

jquery3-autocomplete gem at 1.0.5

jquery-rails gem at 1.0.19

mysql2 gem在0.2.7

autocomplete gem在jquery中按预期工作但我收到一个mysql2错误：

  Job Load (0.4ms)  SELECT jobs.id, jobs.title FROM `jobs` WHERE (LOWER(jobs.title) ILIKE 'te%') ORDER BY jobs.title ASC LIMIT 10
Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ILIKE 'te%') ORDER BY jobs.title ASC LIMIT 10' at line 1: SELECT  jobs.id, jobs.title FROM `jobs` WHERE (LOWER(jobs.title) ILIKE 'te%') ORDER BY jobs.title ASC LIMIT 10
Completed 500 Internal Server Error in 131ms

ActiveRecord::StatementInvalid (Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ILIKE 'te%') ORDER BY jobs.title ASC LIMIT 10' at line 1: SELECT  jobs.id, jobs.title FROM `jobs` WHERE (LOWER(jobs.title) ILIKE 'te%') ORDER BY jobs.title ASC LIMIT 10):


# gemfile 
gem 'jquery-rails'
gem 'rails3-jquery-autocomplete'

# jobs_controller.rb
  autocomplete :tag, :name
  autocomplete :job, :title

# routes.rb
  resources :jobs do 
    get :autocomplete_tag_name, :on => :collection    
    get :autocomplete_job_title, :on => :collection    
  end

#chrome console
GET http://localhost:3000/jobs/autocomplete_job_title?term=te 500 (Internal Server Error)

有人有什么想法吗？我对这个有点难过。它最近工作，最近破产。很可能是因为我跑了bundle update，但我无法回溯罪魁祸首，或确认这实际上是问题。

编辑：固定问题：我正在使用Heroku所以我偶然在我的开发环境中加载了PostgreSQL gem。开发环境使用mysql。这解决了我的问题 - 我希望它可以帮助别人。

group :production do
  gem 'pg'
end

group :production do
  gem 'pg'
end

在Rails应用程序中，jquery autocomplete gem因mysql2错误而失败
