Tomeu,
At the moment I'm just letting datatables.net enhance a plain html table
for me. One of these days I'll probably get around to giving it a json
datasource but so far it hasn't been a priority for my usage.
As a bonus, here's some of how to update the datatables.net display after
using the edit dialog. (So just the edited record's row in the datatable
gets updated rather than a full page refresh)
In controller
#after you'd done the necessary DB updates...
#tell browser to close the jqueryui dialog
response.js =XML( '$("#edit_dialog").dialog("close");')
#prepare for display update
edit_icon = IMG(_src=URL(c="static",f="images/page_white_edit.png"),
_alt="Click
to edit")
#prep javascript code for datatables.net to update the existing row's
display
#basically just a json list of td values
row_update = simplejson.dumps([updated_record.table.first_name,
updated_record.table.last_name, updated_record.table2.name,
str(A(edit_icon, _href=URL(r=request,f='edit_loader', args=[
updated_record.table.record_id, mode]), _class="updateDialog")),
updated_record.table.email, updated_record.table.someother_id])
#using the tr#id method to update table is unreliable (the TR won't have an
id if it was added dynamically
#instead use the row index provided by datatables.net itself (we passed it
in via ajax vars)
#essentially fnUpdate(new td values, which row)
response.js += '$("#your_table_selector").dataTable().fnUpdate( '+row_update
+', '+request.vars['datatable_row_index']+',0, false );'
#also using jGrowl to give an acknowledgement
message = T("%s updated") % (updated_record.table.first_name)
response.js += '$.jGrowl("'+message+'");'
And as the second bonus, how to insert a brand new row in the datatable.
(Below my datatable.net is another always visible LOAD()ed form for
creating a new record. Upon submission the new record is inserted into the
existing datatable via javascript returned in web2py's response)
In controller:
#do the database insert then
#prepare for display update
edit_icon = IMG(_src=URL(c="static",f="images/page_white_edit.png"),
_alt="Click
to edit")
table_update = simplejson.dumps([new_record.table.first_name, new_record.
table.last_name,
new_record.table2.name, str(A(edit_icon, _href=URL(r=request,f=
'edit_loader',
args=[new_record.table.record_id, form.vars.mode]), _class=
"updateDialog")),
new_record.table.email, new_record.table.foreign_id])
#issue command for adding new row to datatable
response.js = 'vol_table.fnAddData('+table_update+');'
Good luck
~Brian
