Question

我是ROR的新手，我按照tutorial来学习ROR，但是，它显示错误

<%= form_for([@post, @post.comments.build]) do |f| %>
<%= f.error_messages %>
<div class="field">
    <%= f.label :commenter %>
    <br/>
    <%= f.text_field :commenter %>
</div>
<div class="field">
    <%= f.label :body %>
    <br/>
    <%= f.text_area :body %>
</div>
<div class="actions">
    <%= f.submit %>
</div>
<% end %>

在Aptana Studio中，它说：

ActionView::TemplateError (compile error
/home/ming/new/app/views/posts/show.html.erb:31: syntax error, unexpected ')'
...post.comments.build]) do |f| ).to_s); @output_buffer.concat(...
                              ^
/home/ming/new/app/views/posts/show.html.erb:51: syntax error, unexpected kENSURE, expecting ')'
/home/ming/new/app/views/posts/show.html.erb:53: syntax error, unexpected kEND, expecting ')') on line #31 of app/views/posts/show.html.erb:
28: <% end %>
29: 
30: <h2>Add a comment:</h2>
31: <%= form_for([@post, @post.comments.build]) do |f| %><%= f.error_messages %>
32: <div class="field">
33:     <%= f.label :commenter %>
34:     <br/>

那么，任何想法？

Answer 1

你有错误，应该是：

<% form_for ....

没有=

Answer 2

使用<% form_for...代替<%=

这是因为在Ruby2 +中，<%= form_for..更改为<% form_for..

<%= form_for将适用于ruby 1.9.3。
