我有代码:
<% generate_bullets = Bullet.all %>
<% generate_bullets.shuffle.first(4).each do |t| %>
<%= f.text_field, :bullets, :class => 'text_field disabled' %>
我想禁用使用嵌入式ruby的文本框,但我无法这样做.如果我能得到任何有关我所面临的情况的帮助,我将非常感激.
禁用文本框后,我想让一个按钮从数据库表"bullets"生成四个随机ID,并以数组格式在禁用的文本框中打印它们,并利用这四个打印的ID将它们发布到创建的页面上.任何帮助都会更好.
我有一个spork gem问题.每次我运行spork命令时都会遇到这个长错误:
