我是makine的商业目录，我在城市和地区的商业目录页卡住了。
我做了一个简单的企业目录。所有我想要三个查询;例如，类别名称：制造业

• • 第一页：**我想要这样的一页：slug（这个slug的意思是类别名称）/（我做了，我对这个页面没有问题。
    **Second:**City url like this abc.com/directory/category/slug:slug/(city name with slug style)/. forexample abc.com/category/manufacturing/london/
• • 第三个：**地区网址如下：abc.com/directory/category/slug：slug/（带有鼻涕虫样式的城市名称）/。例如：abc.com/category/manufacturing/london/southwark（地区名称）

我只做了第一个第二个和第三个让我发疯...
我试过很多方法都失败了...
下面是我的代码：
