how can i put validation check in Datagrid Fields ??
follw. is my Datagrid :
*/DataGridField('mr_inp_form',
searchable = True,
required=True,
#accessor = 'getMr_inp_form',
columns=("program", "activity",
"a_startdate","a_enddate","status", "act_desc"),
widget = DataGridWidget(
description="Fill Activity Related Details here :",
columns={
'program' : SelectColumn("Select Program",
vocabulary="getprog", default="---"),
'activity' : SelectColumn("Select Activity",
vocabulary="getactv", default="---"),
'a_startdate' : ColumnImg("select activity start
date"),
'a_enddate' : ColumnImg("selct activity end date"),
'status' : SelectColumn("Select Status",
vocabulary="getstatus", default="---"),
'act_desc' : Column("enter activity description
here"),
#'testdatefield' : SelectColumn('test',
vocabulary="listdate", default="---")
#'testdatefield' : DateBoxWidget()
#'testdatefield' : ColumnImg('testdatefield')
},
),
i18n_domain = "plone",
),
/*
Now i want to individually put validation, like, "required=True" for all
Datagrid fields, so that, if user missed out on any one of fields, an
error will be generated .
can i achieve this ?
thanks for any inputs
Just googled around and found this tutorial.
Perhaps this will help you writing your DataGridField valdiator.
http://www.pererikstrandberg.se/blog/index.cgi?page=PloneArchetypesFieldValidator
If you use Archetypes content types you can implement a validator very
easy using 'validate_[fieldname]' as function name.
def validate_station_matrix(self, datagridstuff):
errors = 0
# do your datagrid checks here
for row in ...
for col in ...
if errors > 0:
return "This field is required, please provide some information."
regards
saily
