我开始使用带有rails 3.2.7和ruby 1.9.3p448（2013-06-27修订版41675）[i686-linux]的'Agile Web Development with Rails，第4版'来学习rails。当我尝试编辑html表单时

   <%= f.text_area :description  :rows=>6 %>

it returned an error

它返回了一个错误

       /media/ashku/New Volume/RoR/depot/app/views/products/_form.html.erb:19: syntax error, unexpected ':', expecting ')'
...= ( f.text_area :description  :rows=>6 );@output_buffer.safe...

then i tried to change the :rows=>6 to rows: 6 but the results where the same

然后我试着改变：rows => 6到行：6但结果在哪里相同

3 个解决方案

#1

You have missed the comma(,) after tag name ie.(:description). So replace your tag with following and try to run..

您错过了标记名称之后的逗号（，），即。（：description）。所以用以下内容替换你的标签并尝试运行..

<%= f.text_area :description, :rows => 6 %>

#2

You're missing a comma in between :description, and :rows.

您之间缺少逗号：description和：rows。

#3
