Accessing values from additional field in sqlform.grid for all rows- Help Needed

[PremKumar KrishnaKumar]

Hi,
  

I am new to Web2Py and would like to achieve 'selectable' like functionality through links but I am not sure how to pass the ID and flag from checkbox to the controller function

Why links why not selectable?

      I might need multiple columns with checkbox and links is the easiest way to achieve it. Also to the controller I wanted to pass both the selected and not selected ids and their flags.

why both selected and not selected?

       For the corresponding ids I would like to update the flag in database to 1 or 0 depending on whether its checked or not.

Code?

testlink=[dict(header="Actioned",body=lambda row: INPUT(_name='actioned',_type="checkbox",_value=id))]

grid = SQLFORM.grid(query
    ,editable=True
    ,details=True
    ,deletable=True
    ,create=True
    ,links=testlink
    ,links_placement='left'
    ,showbuttontext=True
    ,fields=FIELDS
    )
grid = FORM(grid,INPUT(_type="submit",_name="testsubmit",_value="testsubmit"))

if grid.process().accepted:
    print "submit successful"
