Rails 3简单forms错误：无法解析YAML
我的new.html.erb：
New konkurrancer
<%= simple_form_for [:admin, @konkurrancer] do |f| % 我在视图中看到此错误（http：// localhost：3000 / admin / konkurrancers / new）：
Psych::SyntaxError in Admin/konkurrancers#new Showing C:/Rails/konkurranceportalen/app/views/admin/konkurrancers/new.html.erb where line #4 raised: couldn't parse YAML at line 20 column 14 Extracted source (around line #4): 1: New konkurrancer

尝试
<%= simple_form_for ['admin', @konkurrancer] do |f| %>
看起来你是一个名字间隔模型？
您正在使用命名空间模型 – 您必须在表单路径中引用命名空间。
试试这个：
<%= simple_form_for [:admin, @konkurrancer] do |f| %>
