我刚刚在rails app的类别模型上实现了 friendly_id 。之前它曾用于生成这样的URL：
localhost:3000/search?category_id=metal-processing-and-machine-tool
。现在我得到了生成url，如下所示
<a href="<%= search_equipments_path(:category_id => category.slug ) %>">
网址生成线是：
search_equipments def search_equipments
begin
if (params.keys & ['category_id', 'sub_category', 'manufacturer', 'country', 'state', 'keyword']).present?
if params[:category_id].present?
@category = Category.active.find params[:category_id]
else
@category = Category.active.find params[:sub_category] if params[:sub_category].present?
end
@root_categories = Category.active.roots
@sub_categories = @category.children.active if params[:category_id].present?
@sub_categories ||= {}
@countries = Country.active.all
@manufacturers = Manufacturer.active.all
@states = State.active.where("country_id = ?", params[:country]) if params[:country].present?
@states ||= {}
unless params[:category_id].present? && params[:sub_category].present?
params[:category_id] = @category.id if params[:category_id].present?
params[:sub_category] = @category.id if params[:sub_category].present?
end
@equipments = Equipment.active.filter(params.slice(:manufacturer, :country, :state, :category_id, :sub_category, :keyword)).order("#{sort_column} #{sort_direction}, created_at desc")
else
redirect_to root_path
end
rescue Exception => e
redirect_to root_path, :notice => "Something went wrong!"
end
end
方法如下：
_由于搜索引擎优化的原因，我上面的人告诉我要从网址category_id中删除{{1}}。我尝试通过更改url生成行中的格式。没有帮助。可以请任何人告诉我它是否可行，我该如何实现？
如果需要任何额外信息，请在评论中告诉我。
