    :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.

    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.

<h1>Your Pragmatic Catalog</h1>

전체 텍스트 <p>로 시작하고 </p>로 끝입니다. 왜? 어떻게 이러한 html 태그를 제거 할 수 있습니까? 내 .rb 코드에서 <p></p>을 삭제하려고했습니다. 작동하지 않습니다. 저는 ROR에 정말 새로운입니다. 도와주세요.

Answer 1

product.description 대신 simple_format(product.description)을 사용하면 html 태그를 제거 할 수 있습니다.
