Grails“丢失”在页面上进行任何链接时自定义URL映射 [英] Grails "loses" custom URL mapping when following any links on the page

问题描述

我有一个应用程序，用户可以通过两种方式浏览地图（如缩略图和列表）。

  / map /浏览
 / map / list 
  

现在，我想限制这些视图显示特定用户的地图，例如通过

  / user / 3 / browse 
 / user / 3 / list 
  

所以我创建了映射：

<$ p $ / user / $ userId / browse{
controller =map
action =browse
}

/ user / $ userId / list{
controller =map
action =list
}


现在，我可以转到 / user / 3 / browse ，但只要点击分页链接或更改分页过滤器，网址可以回到 / map / browse 。 如果我在控制器中将 userId 设置为 null ，则会出现错误：

错误500：错误处理essing GroovyPageView：执行标记时出错：无法为映射[/ user /（*）/ list]和参数[[action：list，controller：map，max：20， offset：0，sort：uploadDate，order：desc，userId：null，totalMaps：30]]。参数[userId]是必需的，但未指定！ at /views/map/browse.gsp:26

分页的工作原理如下：

 < div class =paginateButtons> 
 < / div> 
  

我能做些什么，或者什么是实现我想要的正确方式？ p>

_{我不一定需要这个URL映射，我只需要一个很好的方式来说：仅显示一个用户的地图}

解决方案

看来问题不在于您的URL映射配置，而在于您创建链接的方式。我认为如果您使用命名的URL映射：它比现在更清晰，创建分页链接时只需指定url名称。例如：

在UrlMappings.groovy中：

  static mappings = {
 
 name account详细信息：/ details / $ acctNumber{
 controller ='product'
 action ='accountDetails'
} 
} 
  

在视图中 - gsp页面：

 < g：link mapping =accountDetailsparams =[acctNumber：'8675309']> 
显示帐户
< / g：link> 
  

I have an application where users can browse maps in two ways (like thumbnails and in a list)

/map/browse
/map/list

Now, I would like to restrict these views to just show maps of a specific user, for example through

/user/3/browse
/user/3/list

So I created the mapping:

"/user/$userId/browse" {
  controller = "map"
  action = "browse"
}

"/user/$userId/list" {
  controller = "map"
  action = "list"
}

Now, I can go to /user/3/browse, but as soon as I click on a pagination link or change the pagination filters, the URL goes back to /map/browse.

Also, if I set the userId to null in the controller, I get the error:

Error 500: Error processing GroovyPageView: Error executing tag : Unable to create URL for mapping [/user/(*)/list] and parameters [["action":"list", "controller":"map", "max":20, "offset":0, "sort":"uploadDate", "order":"desc", "userId":null, "totalMaps":30]]. Parameter [userId] is required, but was not specified! at /views/map/browse.gsp:26

The pagination works as follows:

<div class="paginateButtons">
    <g:paginate controller="map" action="browse" total="${mapInstanceTotal}"></g:paginate>
</div>

What can I do against that or what would be the correct way of implementing what I want?

_{I don't necessarily need to have that URL mapping, I only need a nice way of saying: "Display maps of only one user"}

解决方案

It seems that the problem is not at your URL mapping configuration ,but in your way to create link. I think it's better if you use Named URL Mapping : it's clearer than your approach now, and when create link for pagination you only need to specify the url name. For example:

In UrlMappings.groovy:

static mappings = {

    name accountDetails: "/details/$acctNumber" {
        controller = 'product'
        action = 'accountDetails'
    }
}

In view - gsp page:

<g:link mapping="accountDetails" params="[acctNumber:'8675309']">
    Show Account
</g:link>
