rails 4 def to_param有2个型号

I came accross something strange when trying to create friendly URLs.

在尝试创建友好的URL时,我遇到了一些奇怪的事情。

I have an item model which has:

我有一个项目模型,其中包括:

def to_param
  "#{id}-#{name}".parameterize
end

This makes my item URLs contain the "ID" and "name" just fine:

这使我的商品网址包含“ID”和“名称”就好了:

www.domain.com/items/ID-name

I also have a category model (item belongs to category and user models) where I have the same def to_param as above but the category URLs stay "unfriendly" no "name" included:

我也有一个类别模型(项目属于类别和用户模型),我有与上面相同的def to_param,但类别URL保持“不友好”,不包括“名称”:

domain.com/categories/ID

I have name column in category table and it has values. I also use ancestry for the category model. Maybe has_ancestry is causing the issue?

我在类别表中有名称列,它有值。我还使用祖先作为类别模型。也许has_ancestry造成了这个问题?

I tried below but no luck:

我试过下面但没有运气:

def to_param
 [id, name.parameterize].join("-")
end

Thanks for any advice!

谢谢你的建议!

Papirtiger的评论引导我找到解决方案。问题是我有这样的链接:

<% @category.children.in_groups_of(4, false) do |childs| %>
 <tr>
 <% for categories in childs %>
 <td>
 <%= link_to "../categories/#{categories.id}" do %><%= categories.name %><% end %></td>
 <% end %>
 </tr>

Beginners solution. :)

初学者解决方案。 :)

Removed the ugly part and now it works:

删除丑陋的部分,现在它的工作原理:

<% @category.children.in_groups_of(4, false) do |childs| %>
 <tr>
 <% for categories in childs %>
 <td><%= link_to categories do %><%= categories.name %><% end %> (<%= Item.where(:category_id => categories.id).count %>)</td>
 <% end %>
 </tr>
