我想在每个规范上清除Redis数据库.

当我通过v键选择一些代码并按s括起来并在括号中关闭时,我收到此错误:

 surround.vim Visual mode s has been remove in favor of S

如何恢复此功能？

我有简单的邮件程序,它发送用户每周摘要和rake任务,向所有用户发送此电子邮件,并将其固定到heroku调度程序.

我想每周向用户发送此电子邮件,但每周只发送一次,无论我运行多少次 rake send_weekly_digest

信封

class DigestMailer < ActionMailer::Base
  include Resque::Mailer
  default from: "company@email.com"

  def weekly_digest(user_id)
    @user = User.find(user_id)

    mail :to => @user.email, :subject => "Weekly Digest"
  end
end

耙任务

desc "Send weekly email digest"
task send_weekly_digest: :environment do
  User.all.each do |user|
    DigestMailer.weekly_digest(user.id).deliver
  end
end

我有一个阵列 [["Company Name", "Field6"], ["Email", "Field5"]]

从该数组我创建具有值的字段数组:

[
  [{:label=>"Company Name", :value=>"gfdgfd"}],
  [{:label=>"Email", :value=>"gfdgfd@gfd.pl"}]
]

运用

fields = [["Company Name", "Field6"], ["Email", "Field5"]]
# first element in array is Label and second is param id
fields_with_values = fields.collect do |field| 
 [
   label: field[0],
   value: params[field[1]]
 ]
end

然后我想将标签和值传递给erb模板(类似):

# template.erb
<% fields_with_values.each do |field| %>
  l: <%= field.label %>
  v: <%= field.value %>
<% end %>

如何收集这些fields_with_values的最佳方式？也许我应该使用Object.new

当我打开quickfix窗口时,我想禁用以下映射.

map <F5> :ZoomWin<cr>

我使用ctags创建了标签文件.

现在,当我尝试使用TAB从缓冲区完成文本时,我也会在弹出窗口中看到所有标签.

如何防止这种情况并且不在完成弹出窗口中显示标签？

我使用SuperTab,没有指定任何选项.

我有使用 jQuery UI 自动完成插件的搜索建议自动完成功能。 http://jqueryui.com/autocomplete/

但是如何在结果弹出项的底部添加其行为类似于 Quora（见下文）。

Javascript

$("#question_search").autocomplete({
  source:$('#question_search').data('source'),
  html: true,
  appendTo: "#search_results",
  select: function( event, ui ) {
    window.location=ui.item.value;
    return false;
  },
  focus: function( event, ui ) { },
  open: function( event, ui ) { });

看法

<div id="question_search_form">
  <input type="text" id="question_search" data-source="<%= new_search_url %>" />
  <div id="search_results"></div>
</div>

我正在跟踪用户活动:

def track
   UserActivityTracker.new(date: Date.today.to_s).track
end

#application.rb
config.time_zone = 'UTC'

如何确保在Pacific Time (US & Canada) 时区中跟踪日期.我不想改变时区application.rb

我想在Mail erb模板中用作body.当我在Pony gem上设置它时,它可以工作.

post 'test_mailer' do
  Mail.deliver do
    to ['test1@me.com', 'test2@me.com']
    from 'you@you.com'
    subject 'testing'
    body erb(:test_mailer) # this isn't working
  end
end

private

fields = [1, 2] # some array

ERB文件

<% fields.each do |f| %>
  <%= f %>
<% end %>

我有下面的帮助,应该把日期放在单词取决于数字:

def day_in_words(number)
    case number
    when 0
      "Sunday"
    when 1
      "Monday"
    when 2
      "Tuesday"
    when 3
      "Wednesday"
    when 4
      "Thursday"
    when 5
      "Friday"
    when 6
      "Saturday"
    when 7
      "Sunday"
    when 8
      "Monday"
    when 9
      "Tuesday"
    when 10
      "Wednesday"
    when 11
      "Thursday"
    ...
    when 16
      "Sunday"
    when 17
      "Monday"
    when 18
      "Tuesday"
    when 19
      "Wednesday"
    when 20
      "Thursday"
    when 21
      "Friday"
    else
      "Unknown Day"
    end
  end
