我想在我的视图中使用Ace Editor来创建帖子对象,而不是textarea,但Ace Editor需要使用<div>
来包含其内容。我是Ruby on Rails的新手4我试图找出如何使用Ace Editor安全地提交用户输入,并将用户重定向到显示帖子提交后的页面。这是我目前提交尚未使用Ace编辑器<div>
...
<%= form_for(@post) do |f| %>
<div class="field">
<%= f.label :title %><br>
<%= f.text_field :title %>
</div>
<div class="field">
<%= f.label :description %><br>
<!-- I'd like to replace this text_area with the ace editor div-->
<%= f.text_area :description %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
如何用<div>
替换f.text_area元素并在表单的帖子请求中包含它的内容?

使用新版本的ace,您也可以使用textarea
