HAML:form_tag困境(缩进？)

Question

我正在制作"用户设置表单",并坚持使用HAML:

= form_tag('/')
  - [1,2,3].each do |i|
    =  check_box_tag "accept#{i}"
  = submit_tag

这导致"语法错误,意外的kENSURE,期待$ end".

工作变体是

= form_tag('/')
  - [1,2,3].each do |i|
  =  check_box_tag "accept#{i}"
  = submit_tag

结果是

 <input id="accept1" name="accept1" type="checkbox" value="1" />
    <input name="commit" type="submit" value="Save changes" />
    <input id="accept2" name="accept2" type="checkbox" value="1" />
    <input name="commit" type="submit" value="Save changes" />
    <input id="accept3" name="accept3" type="checkbox" value="1" />
    <input name="commit" type="submit" value="Save changes" />
    <form action="/" method="post"><div style="margin:0;padding:0;display:inline"><input name="authenticity_token" type="hidden" value="tuniieYp9hgvGBMaYDjK2l3Mgjpxo9F1LPzqEF4ykHg=" /></div>

错误:控制外部表格标签,3次提交按钮.

任何有关修复的想法都将受到赞赏.谢谢!

Answer 1

您应该将块传递给form_tag.我想你想要:

Rails 2.x:

- form_tag('/') do
  - [1, 2, 3].each do |i|
    = check_box_tag "accept#{i}"
  = submit_tag

Rails 3+:

= form_tag('/') do
  - [1, 2, 3].each do |i|
    = check_box_tag "accept#{i}"
  = submit_tag
