Feature Request - Total Count of Data in Pagination

[kevintanhongann]

I'm working with Grails JSON Views and discovered that it's not configurable in a few ways.

1. Count of the total rows of data cannot be enabled in jsonapi.render(). If I don't know the total count of the data, how can I construct my pagination view in pure html format such as this:

I can make another API call to specifically know the count of my rows of data. But if this can be enabled and be shown in the json output would be better.

{
      data: [],
      links: {},
      total: '40'
}

The only place this could be put is in the meta object

One way to do it is shown in the project at https://github.com/jeffbrown/issue152.

import demo.Widget
import grails.gorm.PagedResultList

model {
    PagedResultList<Widget> widgetList
}

json {
    total widgetList.totalCount
    data tmpl.widget(widgetList)
}

(note that total increases from 100 to 101 after the POST)

$ curl http://localhost:8080/widget
{"total":100,"data":[{"id":1,"name":"Widget 0"},{"id":2,"name":"Widget 1"},{"id":3,"name":"Widget 2"},{"id":4,"name":"Widget 3"},{"id":5,"name":"Widget 4"},{"id":6,"name":"Widget 5"},{"id":7,"name":"Widget 6"},{"id":8,"name":"Widget 7"},{"id":9,"name":"Widget 8"},{"id":10,"name":"Widget 9"}]}
$ 
$ curl -X POST -d '{"name":"Some New Widget"}' -H "Content-Type: application/json" http://localhost:8080/widget
{"id":101,"name":"Some New Widget"}
$ 
$ curl http://localhost:8080/widget
{"total":101,"data":[{"id":1,"name":"Widget 0"},{"id":2,"name":"Widget 1"},{"id":3,"name":"Widget 2"},{"id":4,"name":"Widget 3"},{"id":5,"name":"Widget 4"},{"id":6,"name":"Widget 5"},{"id":7,"name":"Widget 6"},{"id":8,"name":"Widget 7"},{"id":9,"name":"Widget 8"},{"id":10,"name":"Widget 9"}]}
