如何在节点书架模型中定义列名?

I'm using Bookshelf in my NodeJs application for database manipulation

我在NodeJs应用程序中使用了Bookshelf来进行数据库操作。

I need when I execute:

我执行时需要:

User = bookshelf.Model.extend({
    tableName: 'users'
});

new User({
   firstName: "John",
   lastName: "Paul"
}).save();

It will need saving values in 'first_name' and 'last_name' columns

它需要在“first_name”和“last_name”列中保存值

How to can I do define this?

我怎么定义这个呢?

Apparently there is no built in method to do this. However I just asked this in #bookshelf irc and somebody told me :)

显然没有内置的方法来实现这一点。然而，我在#bookshelf irc上问过这个问题，有人告诉我:

var STRING_CAMELIZE_REGEXP = (/(\-|_|\.|\s)+(.)?/g);
var STRING_UNDERSCORE_REGEXP_1 = (/([a-z\d])([A-Z]+)/g);
var STRING_UNDERSCORE_REGEXP_2 = (/\-|\s+/g);

function camelize(str) {
  return str.replace(STRING_CAMELIZE_REGEXP, function(match, separator, chr) {
    return chr ? chr.toUpperCase() : '';
  }).replace(/^([A-Z])/, function(match, separator, chr) {
    return match.toLowerCase();
  });
}

function underscore(str) {
  return str.replace(STRING_UNDERSCORE_REGEXP_1, '$1_$2').
    replace(STRING_UNDERSCORE_REGEXP_2, '_').toLowerCase();
}


var _ = require('lodash');
var Podcast = bookshelf.Model.extend({
  parse: function(attrs) {
    return _.reduce(attrs, function(memo, val, key) {
      memo[camelize(key)] = val;
      return memo;
    }, {});
  },
  format: function(attrs) {
    return _.reduce(attrs, function(memo, val, key) {
      memo[underscore(key)] = val;
      return memo;
    }, {});
  }
});


var p = new Podcast();
p.set('lastUpdated', new Date());

To elaborate, this will turn camelCase into snake_case.

详细说明一下，这将使camelCase变成snake_case。
