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":"uploadDa开发者_StackOverflow中文版te", "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="${mapInstanceTotal}"></g:paginate>
</div>
What can I do against that or what would be the correct way of implementing what I want?
I don't necessarily need to have that URL mapping, I only need a nice way of saying: "Display maps of only one user"
It seems that the problem is not at your URL mapping configuration ,but in your way to create link. I think it's better if you use Named URL Mapping : it's clearer than your approach now, and when create link for pagination you only need to specify the url name. For example:
In UrlMappings.groovy:
static mappings = {
name accountDetails: "/details/$acctNumber" {
controller = 'product'
action = 'accountDetails'
}
}
In view - gsp page:
<g:link mapping="accountDetails" params="[acctNumber:'8675309']">
Show Account
</g:link>
