小编zor*_*ras的帖子

我有这个字符串,我想知道如何将其转换为哈希.

"{:account_id=>4444, :deposit_id=>3333}"

我想按月对帖子进行分页,所以我在Post模型中添加了以下范围

class Post
  include Mongoid::Document
  include Mongoid::Timestamps

  scope :by_month, lambda {|end_date| Post.order_by(:created_at => :asc).where(:created_at.gte => (end_date.to_date.beginning_of_month), :created_at.lte => (end_date.to_date))}
end

在我的控制器中我放了

def show
  @posts = Post.by_month(Time.now).page(params[:page]).per(20)
end

在视野中

<%= paginate @posts, :theme => 'month_theme' %>
<%= render @posts %>

问题:

1. 分页不按月工作,我想在页面中显示一个月的所有结果,用params [:month] = 2或params [:month] = Feb替换params [:page]
2. 如何查看"2011年8月"而非1,2
3. 循环月份和年份,就像你在'2011年1月'中转到之前一样,它将转到'2010年12月'

我正在使用ruby 1.9来解析以下带有MacRoman字符的csv文件

# encoding: ISO-8859-1
#csv_parse.csv
Name, main-dialogue
"Marceu", "Give it to him ó he, his wife."

我做了以下解析这个.

require 'csv'
input_string = File.read("../csv_parse.rb").force_encoding("ISO-8859-1").encode("UTF-8")
 #=> "Name, main-dialogue\r\n\"Marceu\", \"Give it to him  \x97 he, his wife.\"\r\n"

data = CSV.parse(input_string, :quote_char => "'", :col_sep => "/\",/")
 #=> [["Name, main-dialogue"], ["\"Marceu", " \"Give it to him  \x97 he, his wife.\""]]

所以,问题是数据中的第二个数组是单个字符串而不是2个字符串,如: ["\"Marceu\"", " \"Give it to him \x97 he, his wife.\""]] 我试过:col_sep => ","(这是默认行为),但它给了我3个分裂.

header = CSV.parse(input_string, :quote_char …
