问题描述
我实现了一个带有所有正确操作和视图的 restfull 控制器.它目前与 new_html.erb 视图完美配合，该视图使用包含如下结构的 form_for:
I implemented a restfull controller with all the correct actions and views. It works currently perfectly with a new_html.erb view that uses a form_for containing a structure like:
<% form_for @ecard do |f| %>
在看一些教程时，我看到人们也使用这种结构:
when watching some tutorials i saw that people also use the structure:
<% form_for :ecard do |f| %>
这听起来合乎逻辑..但是当我尝试使用 <% form_for 时:ecard do |f|%> 结果帖子转到不同的操作，然后使用 <% form_for @ecard do |f|%>..
It sounds logical.. but when i try to use the <% form_for :ecard do |f| %> the resulting post goes to a different action then using <% form_for @ecard do |f| %>..

Marco,
这之前已经在网站上回答过:
This has been answered on the site before:
实例变量与 ruby on rails 中的符号 (form_for)
我希望能解决这个问题.
I hope that clears it up.
