Question

我在点击主页时遇到以下错误。我花了好几个小时试图弄清楚没有运气。查看调试输出，似乎member_session对象没有获取成员对象类上可用的任何方法。

此页面包含两个表单，一个用于注册，另一个用于登录。

 NoMethodError in Members#new

    Showing /home/thomas/railsProjects/draughtsWorld/app/views/common/_loginPanel.html.erb where line #23 raised:

Answer 1

这是一个答案：

模型MemberSession不响应昵称

会员是否有专栏nickname？

我认为它应该是username或login，所以请尝试将您的视图更改为：

<%= f.label :username, "Nickname" %>
<%= f.text_field :username, :class => "sign_in_textbox" %>

或

<%= f.label :login, "Nickname" %>
<%= f.text_field :login, :class => "sign_in_textbox" %>

编辑：或者您可以尝试在authlogic配置中指定列名称：

acts_as_authentic do |c|
  c.login_field = :nickname
end

它应该完成这项工作。

Authlogic会话模型不绑定到成员模型
