    Product.create(:title => 'Pragmatic Project Automation', 
    :description => 
    %{<p> 
     <em>Pragmatic Project Automation</em> shows you how to improve the 
     consistency and repeatability of your project's procedures using 
     automation to reduce risk and errors. 
     </p> 
     <p> 
     Simply put, we're going to put this thing called a computer to work 
     for you doing the mundane (but important) project stuff. That means 
     you'll have more time and energy to do the really 
     exciting---and difficult---stuff, like writing quality code.

    Product.create(:title => 'Pragmatic Version Control', 
     :description => 
     %{<p> 
     This book is a recipe-based approach to using Subversion that will 
     get you up and running quickly---and correctly. All projects need 
     version control: it's a foundational piece of any project's 
     infrastructure. Yet half of all project teams in the U.S. don't use 
     any version control at all. Many others don't use it well, and end 
     up experiencing time-consuming problems. 
     </p>}, 
    :image_url => '/images/svn.jpg', 
    :price => 28.50) 
    # . . . 


    Product.create(:title => 'Pragmatic Unit Testing (C#)', 
    :description => 
    %{<p> 
     Pragmatic programmers use feedback to drive their development and 
     personal processes. The most valuable feedback you can get while 
     coding comes from unit testing. 
     </p> 
     <p> 
     Without good tests in place, coding can become a frustrating game of 
     "whack-a-mole." That's the carnival game where the player strikes at a 
     mechanical mole; it retreats and another mole pops up on the opposite side 
     of the field. The moles pop up and down so fast that you end up flailing 
     your mallet helplessly as the moles continue to pop up where you least 
     expect them. 
     </p>},

    end 

    def self.down 
    Product.delete_all 
    end 
end 

當我在以後的頁面顯示「說明」。

<h1>Your Pragmatic Catalog</h1> 
<% for product in @products -%> 
    <div class="entry"> 
     <%= image_tag(product.image_url) %> 
     <h3><%= product.title %></h3> 
     <%= product.description %> 
     <div class="price-line"> 
     <span class="price"><%= product.price %></span> 
     </div> 
    </div> 
<% end %> 

整個文本是<p>開始，以</p>結束。爲什麼？ 我該如何擺脫這些html標籤？ 我試圖刪除我的.rb代碼中的<p></p>。它不工作。 我是ROR的新手。請幫忙。

Answer 1

而不是product.description使用simple_format(product.description)擺脫html標籤。
