应用rails进行敏捷web开发学习日记--创建列表
创建controller并包含index这个action方法
修改app\controllers\store_controller.rb
def index
@products = Product.find(:all,:order=>"title")
end
def add_to_cart
@products = Product.find(params[:id])
end
end
在app\views\layouts\ 目录下创建布局模板store.html.erb
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="content-type" content="text/html;charset=UTF-8" />
<title>Store: <%= controller.action_name %></title>
<%= stylesheet_link_tag 'depot' %>
</head>
<body>
<div id="header">
<h1>Store</h1>
</div>
<div id="globalnav">
</div>
<div id="tools">
<p id="notice"><%= flash[:notice] %></p>
</div>
<div id="body">
<%= yield %>
</div>
<div id="footer">
<p class="center"><%=Time.now%></p>
</div>
</body>
</html>
修改app\views\store\index.html.erb
<h2>index</h2>
<% @products.each do |product| %>
<ul class="<%=cycle('list_odd','list_even')%>">
<li class="image"> <img src="<%=product.image_url %>"/></li>
<li class="id"><%=product.id%></li>
<li class="title"><%=h(product.title).titleize %></li>
<li class="description"><%=h(product.description) %></li>
<li class="price"><%=number_to_currency(h(product.price)) %></li>
<%=button_to"Add to cart",:action=>:add_to_cart,:id=>product%>
</ul>
<% end %>
创建add_to_cart.html.erb
<h2>add_to_cart</h2>
<ul>
<li class="image"> <img src="\<%=@products.image_url %>"/></li>
<li class="title"><%=h(@products.title).titleize %></li>
<li class="price"><%=number_to_currency(h(@products.price)) %></li>
</ul>
<%= link_to 'Back To Store', :action=>"index" %>
