我试图找出一种方法来计算包含html的特定字符串中的单词.

示例字符串:

<p>Hello World</p>

Ruby中有没有办法计算p标签之间的单词？或者这个问题的任何标签？

例子:

<p>Hello World</p>
<h2>Hello World</h2>
<li>Hello World</li>

提前致谢!

编辑(这是我的工作代码)

控制器:

class DashboardController < ApplicationController
  def index
    @pages = Page.find(:all)
    @word_count = []
  end

end

视图:

<% @pages.each do |page| %>

        <%  page.current_state.elements.each do |el| %>
            <% @count = Hpricot(el.description).inner_text.split.uniq.size  %>
            <% @word_count << @count %>
        <% end %>

            <li><strong>Page Name: <%= page.slug %> (Word Count: <%= @word_count.inject(0){|sum,n| sum+n } %>)</strong></li>

<% end %>

无论如何回应.yml文件扩展名？

我试过了,但无法让它发挥作用.

respond_to do |format|
      format.xml # index.xml.builder
      format.yml {render :text => @labels.to_yaml, :content_type => 'text/yaml'}
    end

上面的代码吐出以下错误 uninitialized constant Mime::YML

我试图用TDD让我的头"脏",出于某种原因,当我bundle exec rake test在命令行上运行时,没有任何反应.

这是我的RakeFile:

require 'rake/testtask'

Rake::TestTask.new do |test|
  test.libs << 'test'
end

desc "Run Tests"
task :default => :test

这是我的测试文件:

require 'test/unit'

class TestMygem < Test::Unit::TestCase
  def test_silly_example
    assert_equal 2+2, 5
  end
end

我有以下型号:

class Contact
  attr_accessor :name, :emails, :message

  def initialize(attrs = {})
    attrs.each do |k, v|
      self.send "#{k}=", v
    end
  end

  def persisted?
    false
  end
end

我在我的视图中呼吁联系表格如下:

<div class="email_form">
   <%= render 'form' %>
</div>

这是控制器:

class ShareController < ApplicationController
  layout "marketing_2013"
  respond_to :html, :js

  def index
    @contact = Contact.new
  end
end

这是表格:

<%= form_for(@contact) do |f| %>
    <%= f.label :name, "Your Name" %>
    <%= f.text_field :name %>
    <%= f.label :text, "Send to (separate emails with a comma)" %>
    <%= f.text_field :emails …

我有以下内容 form_for

<div class="multiple_students">
        <%= f.label :multiple_classes, "Do you teach multiple classes?" %>
        <%= f.radio_button :multiple_classes, 1, checked: @user.multiple_classes?, class: 'multiple_classes', data: { question: 'What is your average class size?' } %> <%= f.label :multiple_classes, "Yes", class: 'multiple_classes' %>
        <%= f.radio_button :multiple_classes, 0, checked: @user.multiple_classes?, class: 'multiple_classes', data: { question: 'How many kids do you teach?' } %> <%= f.label :multiple_classes, "No", class: 'multiple_classes' %>
    </div>
    <div class="number_of_students hide">
        <%= f.label :students %>
        <%= f.text_field :students, :class=>"student_count required digits" %> …

在我的应用程序中有Athletes...运动员可以有很多运动.

运动员:

has_many :sports, :through => :user_sports
has_one :primary_sport, conditions: ["user_sports.primary = ?", true], class_name: "Sport"
has_many :user_sports

UserSport:

class UserSport < ActiveRecord::Base
  attr_accessible :athlete_id, :sport_id, :primary

  belongs_to :athlete
  belongs_to :sport
end

我试图能够拉回primary_sport作为Sport对象而不是user_sport对象.

我正在尝试使用Rails 3设置OAuth提供程序服务器,但似乎无法找到任何可以实现此目的的内容.

当涉及到oauth时,我也是一个新手,所以请原谅我的无知.

在设置oauth服务器时,我是否需要在agree2.com这样的地方拥有oauth帐户？或者我可以使用自己的服务器吗？

我正在使用一个 Rails 应用程序，我需要返回特定行的最大值，但还需要返回行的其余内容。

代码：

medias = Media.maximum(:id, :conditions => ['medias.image = true AND medias.subscriber_id  = 37'], :group => ['subscriber_id'])

这仅返回 id 和subscriber_id，我需要返回所有行而不仅仅是这两个行。

示例：在我的媒体表中，订阅者可以上传多张照片。我正在尝试按订阅者 ID 分组并获取所有订阅者的最后一个条目。所以基本上我需要一个最大的查找。

这是我的API的样子:

module ServiceRequests
  class API < Grape::API
    version 'v1', using: :path
    format :json

    namespace :companies do
      params do
        requires :company_id, type: Integer, desc: "A Company Id"
      end

      resource :service_requests do
        get :all do
          Company.find(params[:company_id]).service_requests
        end
      end
    end

  end
end

我试图像这样打电话:http://localhost/v1/companies/:company_id/service_requests/all但是当我打这个电话时,我收到了错误No route matches [GET] "/v1/companies/1/service_requests/all"

工作守则:

module ServiceRequests
  class API < Grape::API
    version 'v1', using: :path
    format :json

    resource :companies do

      params do
        requires :company_id, type: Integer, desc: "A Company Id"
      end

      route_param :company_id do
        resource :service_requests do …
