Rails：编译错误，以整数开头的属性名称

我有编译错误。你们能帮我找到答案吗？这在我看来，（在特定5prime_primer第三行）：Rails：编译错误，以整数开头的属性名称

<tr> 
     <td><%=relation.AmpInfoName%></td> 
     <td><%=relation.5prime_primer%></td> 
     <td><%=relation.3prime_primer%></td> 
     <td><%=relation.Selective_bases_1%></td> 
     <td><%=relation.Selective_bases_2%></td> 
</tr>

产生以下错误：

compile error

...tput_buffer.append= (relation.5prime_primer);@output_buffer....

难道你们帮我找出如何解决这个问题？

与大多数语言一样，ruby标识符可能不以数字字符开头。 – 2012-01-12 20:19:21

你建议我做什么？我没有建立这个数据库，我坚持使用它。 – bdeonovic 2012-01-12 20:23:30

Ruby方法名称不能以数字开头。然而，你可以定义你自己来完成：

class Foo < ActiveRecord::Base 
    def three_prime_primer 
    read_attribute '3_prime_primer' 
    end 

    def three_prime_primer=(value) 
    write_attribute '3_prime_primer', value 
    end 
end

它不会是很难在一个小方法来包装这件事，让你可以做

access_attribute '3_prime_primer', :as => 'three_prime_primer'

你快到了那里比我快一点:)谢谢 – bdeonovic 2012-01-12 20:58:15

我在模型中定义的方法，然后抬起头来使用HashMap中的属性：

class AmplificationInfoTable < ActiveRecord::Base 
     attr_accessor :all 
     def fiveprime_primer 
       attributes["5prime_primer"] 
     end 
end

这让我做的事情，如：

relation.fiveprime_primer

和平！
