DATE字段的Rails腳手架問題

Question

當我使用Rails腳手架時，我無法訪問該頁面來編輯字段。它向我展示了所有DATE字段的一些問題。這裏的錯誤：

can't convert Symbol into String 

Extracted source (around line #124): 

    121: </p> 
    122: <p> 
    123:  <%= f.label :dataDeCadastro %><br /> 
    124:  <%= f.date_select :dataDeCadastro %> 

和部分堆棧跟蹤的：

拿什麼是？

Answer 1

我已經找到了解決方案上this link這one：

When in your application you have set the I18n.locale to something different than "en" and you have the following simple code in your view:

<%= date_select("user_info", "birthdate") %> 

You'll get the can't convert Symbol into String for the date_select helper. The problem can be rescued by giving the date_select helper order like this:

<%= date_select("user_info", "birthdate", :order => [:day,:month,:year]) %> 

or by doing order in the yml file usually located at config/locales/your_lang.yml like this

date: 
    formats: 
    default: "" 
    long: "" 
    short: "" 
    order: 
    - :year 
    - :month 
    - :day 

Answer 2

你能否也顯示錯誤信息？

UPDATE：

<p> 
    <%= f.label :dataDeNascimento, "Data de Nascimento" %> 

    <%= f.date_select "dataDeNascimento" %> 
</p> 

或試試這個：

<p> 
    <%= f.label :dataDeNascimento, "Data de Nascimento" %> 

    <%= date_select "usario", "dataDeNascimento" %> 
</p>

這是極有可能通過定位所致。您輸入的標準語言環境不同於：en（在application.rb或environment.rb中），但是您尚未爲月份名稱聲明合適的翻譯，導致導軌無法使用。您可以從GitHub下載標準翻譯文件。
