ruby-on-rails - 错误：在 Ruby on rails 中运行应用程序时无法将字符串转换为整数

Question

显示第 156 行引发的 app/views/student/edit.erb ：

can't convert String into Integer

提取的源代码（在 #156 行附近）：

154:<div class="label-field-pair">
155:<label for="student_country"><%= t('select_native') %></label>
156:<div class="text-input-bg_form"> <%= select :student,  :select_native, [["Arab","arab"]["Non Arab","non_arab" ]],  { :prompt => "#{t('select_native')}" } %> </div>
157:</div>
158: 
159: 

Answer 1

数组中缺少逗号，添加逗号即可。

[["Arab","arab"],["Non Arab","non_arab" ]] 
<%= select :student,  :select_native, [["Arab","arab"], ["Non Arab","non_arab" ]],  { :prompt => "#{t('select_native')}" } %>
