Ruby on Rails-选择选项帮助器
|
有人可以帮助选择帮助者吗，因为我是Ruby On rails的新手。
我有一个如下的json对象，
@response = {\"status\" => \"200\", \"fruit\" => [ {
\"id\" => 1,
\"name\" => \"Apple\"
}, {
\"id\" => 2,
\"name\" => \"Mango\"
} ]
}
<select name=\'fruit\'>
<option value=\"1\">apple</option>
<option value=\"2\" selected>mango</option>
</select>
def selFruit
@resp = Fruit.getFruit # this will return @response object as mentioned above
return @resp[\'fruit\']
end
<%= form_for(:AdminLogin) do |f| %>
<div>
<%= select_tag \"fruit\", options_for_select(selFruit.each{|fruit,key| [fruit[key]=>\'name\',fruit[key]=>\'id\']}) %>
<div>
<% end %>
<select name=\"fruit\" id=\"fruit\">
<option value=\"id1nameApple\">id1nameApple</option>
<option value=\"id2nameMango\">id2nameMango</option>
</select>

<%= select_tag \"fruit\", options_for_select(selFruit.map{|fruit,key| [fruit[\'name\'], fruit[\'id\']]}) %>诧不达
form.select(:fruit, @response[\"fruit\"].map { |f| [f[\"name\"], f[\"id\"]] })
