表似乎失去了，当我试图定义一个'校园'模型在rails和设置复数名称自己 [英] Table seems lost when I try to I define a 'Campus' model in rails and set the plural name myself

问题描述

我需要一张表，名字是校园。但铁路解释为复数，把一切都弄乱。
所以我做了一个小调查，他们建议添加这样的变化：

I need a table whos name is Campus. But rails interprets that as plural, messing everything up. So I did a little research and they suggest to add an inflection like this:

ActiveSupport::Inflector.inflections do |inflect|
  inflect.singular /^(campus)(es)?$/i, '\1'
  inflect.plural   /^(campus)$/i, '\1es'
end

我已将它添加到initializers / inflection.rb文件中。
我创建了一个新的迁移，删除表，并再次创建一个新的名为Campus，期望解决问题，但现在我不能得到的表Campus在控制台：

I have added this in the initializers/inflection.rb file. I created a new migration to drop the table and create a new one again called Campus, expecting to have the problem solved, but now I can't get the table Campus in the console:

$ rails console
Loading development environment (Rails 3.0.10)
1.9.2p290 :001 > Campus
 => Campus(Table doesn't exist) 

我做错了什么？如何解决这个问题？
感谢您的帮助

What am I doing wrong? How can I fix this problem? Thanks for your help

我的校园模式是：

class Campus < ActiveRecord::Base

  validates_presence_of :name
  validates_presence_of :university_id

  has_many :pois, dependent: :destroy
  has_many :events, dependent: :destroy
  has_many :market_items, dependent: :destroy
  has_many :ads_points, dependent: :destroy
  belongs_to :university
end

推荐答案

inflectors.rb 有一些标准代码，您的情况：

inflectors.rb has some standard code that you can adjust for your situation:

# inflect.plural /^(ox)$/i, '\1en'
# inflect.singular /^(ox)en/i, '\1'
# inflect.irregular 'person', 'people'

所以你应该是：

inflect.plural /^(campus)$/i, '\1es'
inflect.singular /^(campus)es/i, '\1'

或者这可能更容易：

inflect.irregular 'campus', 'campuses'

对于这些偏转器，Rails将寻找一个名为校园。由于您的表名为 campus ，因此您必须在 Campus 模型中添加以下内容：

With these inflectors Rails will be looking for a table called campuses. Since your table name is campus, you have to add the following to your Campus model:

set_table_name 'campus'

在更改 inflectors.rb 后，务必重新启动服务器。

Be sure to restart your server after making changes to inflectors.rb.
