很抱歉这个令人困惑的标题,但我不确定究竟是什么问题,因为我不太了解Ruby。无论如何,关于这个问题!
所以我有一个渲染:
<div class="form" id="dept_div">
<span class="label search_label">Department:</span>
<% query = "<option></option>" %>
<% Department.all.each do |d| %>
<% query << "<option>"+d.dept+"</option>" %>
<% end %>
<%=select_tag :major, query.html_safe, class: "search_tag", id: "dept_drop" %>
</div>
我尝试插入这里:
<span class="su_label">
<%= f.label :major %>
</span>
<% if !in_mobile_view? %>
<div class = "su_textfield">
<div class="checkbox">
<% else %>
<div data-role="fieldcontain" class="field_group">
<fieldset data-role="controlgroup" data-type="horizontal">
<% end %>
<!-- check privacy preferences to decide whether box should already be checked -->
<% if !hasnoprefs && @user.privacy_prefs.include?("nomajor") %>
<%= check_box_tag "major", 1, true %>
<% else %>
<%= check_box_tag "major" %>
<% end %>
<%= label_tag 'major', 'Hide' %>
<% if !in_mobile_view? %>
</div>
<%= render 'courses/form_partials/majors' %>
</div>
<% else %>
<%= f.text_field :major, class: "settings_inputfield" %>
</fieldset>
我想要的是变量major(在类User中)成为从渲染中选择的项目(这是一个下拉菜单)。有什么想法吗?
答案 0 :(得分:0)
尝试......
<%= f.collection_select :major, query, :id, :major, {:include_blank => 'None' } %>
