在我的Shop
(姓名= ABC; ID = 10)节目视图中,我想展示附近的商店。因此,我用这个:
<h1>
Shops nearby <span id="title"><%=h @shop.name %></span>
</h1>
<% @shops.each_with_index do |shop, i| %>
<% if shop.geocoded? %>
{
latitude: <%= shop.lat %>,
longitude: <%= shop.lng %>,
html: "<a href='#item_<%= i + 1 %>'><strong><%=h shop.name %></strong></a>",
icon: { image: "<%= APP_CONFIG[:site_url] + '/images/map_blue_' + (i+1).to_s + '.png' %>",
iconsize: [48, 48],
iconanchor: [24,48],
infowindowanchor: [24, 0] }
},
<% end %>
<% end %>
您会注意到h1
实际上显示了当前的商店ABC,其余的each
实际上显示了它附近的所有商店。问题是,它还包括商店ABC,因为它是最近的点。如何让each
排除商店ABC?

other_shops = @shops.reject {|shop| shop == @shop}
然后迭代other_shops
:
other_shops.each_with_index do |shop, i|
...

首先设置@shops时,请使用额外条件"id <> ?", shop.id
