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:

fractalis has offered to look at this

Status

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

HTML Back-end implmentation

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

shn_list()
...
    if request.vars.limit:
        limit = int(request.vars.limit)
        if request.vars.page:
            page = int(request.vars.page)
            start = (page - 1) * limit
            stop = page * limit
            limitby = (start, stop)
        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.
