共有117条记录。
我想做的是在 Property#Show 页面上，这取决于我正在查看的 property 对象上是否存在这些内容，我想显示超棒的字体与这些条目相关的图标。
所以，基本上我需要在这些记录的不同名称和各种超棒的字体图标之间对 link 进行硬编码。
例如，如果 property 有一个 property_feature_option.name.eql? "Car Port"（即上面 table 中的 ID=107），我想显示 fa fa-car。可以有很多 property_feature_options 到超赞字体图标名称的映射。
例如Panic Button, Security Guard & Electronic Security 可以转到 fa fa-bullhorn（仅举个例子）。
我该如何处理？不太确定从哪里开始。
我可能会做这样的事情，我定义了一个纯粹的 Ruby class 只是为了展示，但你可以调整 Rails.
class PropertyFeatureOption
attr_reader :name
ICON_MAP = { "fa fa-car" => ["Car Port"], "fa fa-bullhorn" => ["Panic Button", "Security Guard", "Electronic Security"] }.freeze
def initialize(name)
@name = name
end
def icon
icon = ICON_MAP.select { |k, v| v.include? name }.keys.first || "fa fa-whathever"
icon.to_s
end
end
property_feature_option = PropertyFeatureOption.new("Panic Button")
property_feature_option.icon #=> "fa fa-bullhorn"
property_feature_option = PropertyFeatureOption.new("Not in list")
property_feature_option.icon #=> "fa fa-whathever"
一个选项是@iGian 所说的，将它们放在哈希中。为了保持整洁，你应该把它们放在一个单独的命名空间中：
module FeatureIconizer
module_function
ICONS = {
'Car Port' => 'fa-car',
'Panic Button' => 'fa-bullhorn',
'Security Guard' => 'fa-bullhorn',
...
}
DEFAULT = 'fa-house'
def icon_class(feature)
'fa ' + ICONS.fetch(feature.name, DEFAULT)
end
end
另一个选项，因为您已经在数据库中定义了您的功能，所以也可以在数据库中添加图标。这样你不需要部署来改变一个图标。
