Configuring paging

The DataviewConfig.groovy file is set up by default so that when a Viewpoint DataView page first loads, the page displays the first 20 items in the list. However, you can cause the page to open to a different page of items, and you can customize how many items display on each page. For example, you can set up the Node Management page to display 50 items per page and to open (by default) on the 3rd page of results, so that items 101-150 display when the page loads. These instructions explain how to change the default paging options in the DataviewConfig.groovy file.

To configure paging settings

1. Open the DataviewConfig.groovy file in the $VIEWPOINT_HOME directory, and find the ID of the page you want to modify (for example, if you want to modify the Node Management page, find the nodes section).
2. Locate the "page" element.

nodes = """{
"sort" : {"${DV_SORT_SORT}":[{"name":"ASC"}]},
"page" : {"${DV_PAGE_NUMBER}":0, "${DV_PAGE_COUNT}":20},
"filter" : "{}",
...

The "${DV_PAGE_NUMBER}" value corresponds to the item page number that will display when the page loads—0 is the first page, 1 is the second, and so on. The "${DV_PAGE_COUNT}" value is the number of items that appear per page.

3. To change the number of items that appear on a page, change the "${DV_PAGE_COUNT}" value. For example, if you wanted 10 items to display per page, specify 10:

nodes = """{
"sort" : {"${DV_SORT_SORT}":[{"name":"ASC"}]},
"page" : {"${DV_PAGE_NUMBER}":0, "${DV_PAGE_COUNT}":10},
"filter" : "{}",
...

4. To change which item page the page opens to by default, change the "${DV_PAGE_NUMBER}" value. A value of 1 opens on the second page of items; a value of 2 opens on the third page, etc. For example, if you want to open on the 5th page of results, specify 4:

nodes = """{
"sort" : {"${DV_SORT_SORT}":[{"name":"ASC"}]},
"page" : {"${DV_PAGE_NUMBER}":4, "${DV_PAGE_COUNT}":10},
"filter" : "{}",
...

5. Save your changes to the DataviewConfig.groovy file.
6. Go to the Configuration Home page in Viewpoint, and verify that your JSON syntax is still correctly validated. For more information, see Fields: Configuration Home.
