Subject [jira] Commented: (ABDERA-168) Generating page links
Date Wed, 18 Jun 2008 14:54:45 GMT

    [ https://issues.apache.org/jira/browse/ABDERA-168?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12605975#action_12605975

James M Snell commented on ABDERA-168:
--------------------------------------

You could use a URI Template to do this by setting the template pattern and passing in the
current uri parameters in the context with the appropriate changes for the page. e.g. something
like:

  Template template = new Template("?{-join|&|a,b,c,d,page}");
  Map<String,Object> context = new HashMap<String,Object>();
  context.put("a", request.getParameter("a"));
  context.put("b", request.getParameter("b"));
  context.put("c", request.getParameter("c"));
  context.put("d", request.getParameter("c"));
  context.put("page", 2);
  String queryString = template.expand(context);

you can then append the expanded querystring to the base request uri

>             Project: Abdera
>          Issue Type: Improvement
>    Affects Versions: 0.4.0
>            Reporter: Remy Gendron
>            Priority: Minor

> Hello all,
> I'm adding glue code in my application to automatically generate and add paging links
to a returned feed.
> I have the necessary information to decide if a link should be there.
> I know how to compute the URI parameters to target another page.
> I know how to add a link to a feed with the FeedPagingHelper class.
> My question is: Is there an easy way provided by Abdera to generate the link by altering
the current request URI parameters? I need to pass thru all the current parameters that define
the feed content returned (eg ?q=xxx&author=yyy&max-results=10) but alter the start-index
parameter to target the new page.
> I can do it manually by getting this information from the RequestContext and building
the new link. But I see a bunch of getLink() methods in the adapter classes. Is there an easy
(or recommended) way of generated new links based on the current request that I haven't seen?
> Another question would be... do you make the paging links relative to the base URI or
do paging links need to be absolute as the examples in RFC5005 seem to indicate?
> Thank you,
> Rémy
