莫里斯線圖日拒絕強制爲字符串的Rails應用程序

Question

我試圖讓這通常是用一個簡單的

date.to_s 

日期爲字符串，但它不工作我嘗試使用JavaScript字符串脅迫。

String(date) 

但這只是給了我幾年。這是我的代碼。

<script> 
    Morris.Line({ 
    element: 'line', 
    data: [ 
    <% metrics_history(current_user.oauth_token, 'page_impressions', 30).each do |k,v|%> 
    { date: String(<%= k%>) , value: <%= v %>}, 
    <% end %> 
    ], 
    xkey: 'date', 
    ykeys: ['value'], 
    labels: ['Value'], 
    parseTime: false 
}); 
</script> 

這就是它返回的結果。

完全卡在這裏。

數據看起來像這樣在瀏覽器

Morris.Line({ 
           element: 'line', 
           data: [ 
           { date: String(2015-06-18) , value: 0}, 
           { date: String(2015-06-19) , value: 0}, 
           { date: String(2015-06-20) , value: 1}, 
           { date: String(2015-06-21) , value: 0}, 
           { date: String(2015-06-22) , value: 23},

           { date: String(2015-06-24) , value: 11}, 
           { date: String(2015-06-25) , value: 1}, 
           { date: String(2015-06-26) , value: 36},

           parseTime: false 
          }); 

Answer 1

因爲日期是不加引號，使用Javascript將其視爲整數，所以不會在一年之間減法月份和日期。在你的模板，把引號日期：

<% metrics_history(current_user.oauth_token, 'page_impressions', 30).each do |k,v|%> 
{ date: "<%= k%>" , value: <%= v %>}, 

Answer 2

這奏效了

{ date: '<%= raw k%>' , value: <%= v %>}
