從params填充複選框

Question

我有頁面列出了路徑並提供了基於文本的搜索 - 請參見當前版本http://www.trailsee.com/trails。我添加了一個表單來過濾搜索結果，例如通過困難，活動，長度，允許狗等。我有過濾器工作，但它不會加載之前使用過的參數在複選框字段中，用戶可以選擇多個項目，例如在搜索後允許騎自行車，允許遠足等。目前它只加載最大價值的參數。例如如果我有params難度= 0 &難度= 1 &難度2它只會加載難度爲2的頁面。

具體來說：travel_type（radio），：難度（複選框），：狗（複選框）和：action_types（複選框）有問題。

這裏是使用參數的樣品URL http://localhost:3000/trails?utf8=%E2%9C%93&travel_type=on&max_time=168&max_distance=35&difficulty=0&difficulty=1&difficulty=2&dogs=1&dogs=2&action_types=1&action_types=2&action_types=3&commit=Filter

在重載 travel_type 2選擇 難度2選擇 犬2選擇 ACTION_TYPES 3選擇

在這裏被寫在我的視圖代碼苗條

Answer 1

你重寫你的參數[：難度]變量與&difficulty=0&difficulty=1&difficulty=2，你必須給每個複選框一個獨特的參數變量名稱。

div.difficulty 
     strong Difficulty 
     div 
     p 
     = check_box_tag :difficulty0, true, false 
     = label_tag 
      i class='sprite-icon-difficulty-0' 
     = check_box_tag :difficulty1, true, false 
     = label_tag 
      i class='sprite-icon-difficulty-1' 
     = check_box_tag :difficulty2, true, false 
     = label_tag 
      i class='sprite-icon-difficulty-2'
