当我尝试创建新的 GroupLink 时出现此错误

控制器代码：

def new
  @group_links=GroupLink.new
  respond_to do |format|
  format.html { render(:template=> 'group_links/new_link_details', :layout =>      
  '/layouts/sponsored_group_manage_sub_menu') }
  end
end

 def create
   @group_link=GroupLink.new(params[:group_link])
   @group_link.group_id=params[:group_id]
    if @group_link.save
    flash[:notice] = "A new booth link was created!"
     else
    flash[:errors] = @group_link.errors
   end
   redirect_to group_group_links_path(@group)
  end

模型关系是一对多的关联：

 class GroupLink < ActiveRecord::Base
    belongs_to :group
    validates_presence_of :url
    validates_presence_of :text

 def link
   self.url
 end

 def text
  self.text
 end
end

 class Group < ActiveRecord::Base
    has_many :group_links, :dependent => :destroy
 end

路由文件有以下内容：

resources :groups do
 member do
  get :get_group_links
 end

 resources :group_links
 ...
end

视图文件如下：

  <% content_for(:page_title, "Create a New Booth Link") -%>
  <% form_for(:group_link,:url => group_group_links_path, :html => {:id => 
    "new_group_link", :method => :post}) do |f| %>
  <fieldset>
 <h6>New Booth Link</h6>
  <label for="group_link_url">URL</label><br />
  <%= f.text_field :url, :size => 32, :placeholder => "URL for the booth link" %><br    
      /><br />
  <label for="group_link_text">Text</label><br />
  <%= f.text_field :text, :size => 32, :placeholder => "The text for this booth 
     link" %><br/><br />
     <div class="buttons">
 <%= f.submit "Create Booth Link", :class => "button large" %>
    </div>
    </fieldset>
 <% end %>

当我错误地将模型创建为 group_links 而不是 group_link 时，问题就开始了。所以我回滚了迁移并销毁了模型并使用正确的名称重新创建了它。在我进行此更改后，它开始抛出此错误（它正在使用 group_links 模型正确创建新的组链接，但正如预期的那样，路由 wnet haywire 所以我决定更改它）

请帮忙，我只是无法弄清楚问题是什么......

我看到的问题是方法GroupLink

 def text
  self.text
 end

您正在定义text只是调用自身的方法。尝试删除此方法。
