Server-Side Pagination

Currently we do all pagination client-side which won't be possible to keep doing as we accumulate more data

This will be needed for:

• Request Management System
• Organisation Registry
• Volunteer Registry

fractalis has offered to look at this

Status

• The Back-end is now done for HTML representation
• The Back-end was already done for JSON representation
• The Front-end still needs doing

Front-end implementation

• ​http://datatables.net/examples/data_sources/server_side.html

JSON Back-end implementation

Support already present in modules\s3xrc.py

HTML Back-end implementation

Patched the models\01_RESTlike_Controller to support http://S3_PUBLIC_URL/module/resource?limit=x&start=y

shn_list()
...
     if request.vars.limit:
        limit = int(request.vars.limit)
        if request.vars.start:
            start = int(request.vars.start)
            limitby = (start, start + limit)
        else:
            limitby = (0, limit)
    else:
        limitby = None
...
items = crud.select(table, query=query,
            ...
            limitby=limitby, 
            ...
            )

Other Options

• Maybe look at the currently-unused modules/webgrid.py.
• pagenav in models\01_RESTlike_Controller seems unused currently...was an older implementation of a webgrid...can probably be removed.
