我正在为我的本地系统（拥有Mac OS X 10.8）建立一个现有的“Ruby On Rails”项目。我已经安装了所有必需的宝石但是，当我尝试为项目加载数据库模式时，它在终端显示错误'找不到表rv_classes' 我是Ruby On Rails的初学者 我现在没有线索如何解决它。提前完成。
终端的响应如下
Cynosures-Mac-mini:sunridgerv cynosure$ bundle exec rake db:schema:load

* 正如它在'blog_posts'表中所说的重复列“ID”...这里是schema.rb中该表的架构*
create_table "blog_posts", :force => true do |t|
t.text "post_title"
t.datetime "post_date"
t.text "post_content"
t.string "post_image"
t.datetime "created_at"
t.datetime "updated_at"
t.string "post_name"
t.integer "ID"
end
答案 0 :(得分：0)
注释掉这一行：
ActiveAdmin.routes(self)
然后运行您的bundle exec rake db:schema:load并取消注释。
关于您的第二个错误，我想您应该从架构中的t.integer "ID"删除blog_posts行。
