我正在开发一个大型的网络图象,我们的数据库图谱显示,大多数表格栏(即一栏是一大例外)都以缩略语标明。
我们想要把 app带到铁路,但根据铁路做法,似乎不应以这种方式预先确定一栏名称。
是否可以使用有一栏名的铁路? 我知道表格名称的序号得到了支持,但我看不出一栏名称。
任何铁路专家在座是否有任何想法?

确实,我看一看预设的栏目有任何问题(不过,它只是借用而已)。
不管怎么说,你有一个用户模型,有<条码>u_ 姓名/代码>,有<条码>。
冷静:User.first.name
而不是:User.first.u_name
为了实现这一点,我建议,你应当把这一未经测试的气象方案放在一个初步的准备者身上。
class ActiveRecord::Base
def self.pretty_columns(prefix)
skipped_columns = ["id"] #add whatever column name you want here
columns.each do |column|
column_name = column.name
unless skipped_columns.include? column_name
unprefixed_col = (column_name.scan /^#{prefix}(.*)/).flatten.first
define_method "#{unprefixed_col}" do
self.send "#{column_name}"
end
define_method "#{unprefixed_col}=" do |value|
self.send(column_name, value)
end
end
end
end
end
接着, 用户模式:
class User < ActiveRecord::Base
pretty_columns :u_
end
