多重选择框在导轨中不起作用 [英] Multiple select box is not working in rails

问题描述

我正在使用以下代码选择多个值.

I am using the following code to select multiple values.

 <select name="video" multiple="multiple" id="form-field-select-2" class="form-control">
 <%video.each do |option|%>
 <option><%=option%> </option>
 <%end%>
 </select>

但是在提交表单后，它没有给出所有选定的值，而不是仅给出最后一个选定的值.

But after submitting form its not giving all selected values,instead of its giving only the last selected value.

如果对这个问题有任何想法，请分享.

Please share if you have any idea about this issue.

推荐答案

 <select name="video[]" multiple="multiple" id="form-field-select-2" class="form-control">
 <%video.each do |option|%>
 <option><%=option%> </option>
 <%end%>
 </select>

您需要通过将名称更改为video[]

You need to make sure that you are sending an array of answers by changing the name to video[]
