Question

所以，我今天让朋友在我的应用程序上工作，现在：表单的url，'website url'部分没有保存，但剩下的就是。不知道为什么会这样。我进入控制台并不得不手动设置它以便在浏览器中显示。

<div class="row">
    <div class="large-6 columns">
<div class="field">
<%= f.label :title %>
<%= f.text_field :title %>
</div>

<div class="field"> 
<%= f.label 'website url' %> 
<%= f.text_area :url %> <----------- this field isn't saving anymore.
</div>
<div class="field">
  <%= f.label :tag_list, "Genres (separated by commas)" %><br />
  <%= f.text_field :tag_list %>
</div>
<p>
<%= f.file_field :track%>
</p>

<div class="actions">
    <%= f.submit value: "Upload" %>
</div>

     def song_params
       params.require(:song).permit(:title, :artist, :bio, :track, :user_id, :tag_list)
     end
  end

Answer 1

在params.require（：song）.permit列表中添加：url是否可以解决问题？

提交后表单输入不保存
