odoo 8 remove sum of total in group by - odoo

Question

I'm using odoo 8 and I want to remove the sum of the total in the group by. Here is my .py
class report_sales_weekly(osv.osv):
_name = "report.sales.weekly"
_description = "report sales weekly"
_columns = {
'div_target_monthly':fields.float('Div Target'),
'div_achievement':fields.float('Div Achievement'),
}
def read_group(self, cr, uid, domain, fields, groupby, offset=0, limit=None, context=None, orderby=False):
if 'div_target_monthly' in fields:
fields.remove('div_target_monthly')
return super(report_sales_weekly, self).read_group(cr, uid, domain, fields, groupby, offset, limit=limit, context=context, orderby=orderby)
report_sales_weekly()
I found this script from https://www.odoo.com/forum/help-1/how-to-remove-sum-of-total-in-group-by-29666, but I get an error when I make grouping in the list page
TypeError: read_group() got an unexpected keyword argument 'lazy'
Any help please? Thank you

Answer 1

The answer in the link is for openerp-7
Odoo 8 defines an optional parameter lazy, you can find an example in account module on how to override the read_group function:
def read_group(self, cr, uid, domain, fields, groupby, offset=0, limit=None, context=None, orderby=False, lazy=True):
# Your code
return super(account_entries_report, self).read_group(cr, uid, domain, fields, groupby, offset, limit, context, orderby, lazy)

Answer 2

You have two errors here: offset called without offset= and bad definition of the base read_group of Odoo 8.
Can you please try with this :
class report_sales_weekly(osv.osv):
_name = "report.sales.weekly"
_description = "report sales weekly"
_columns = {
'div_target_monthly':fields.float('Div Target'),
'div_achievement':fields.float('Div Achievement'),
}
def read_group(self, cr, uid, domain, fields, groupby, offset=0, limit=None, context=None, orderby=False, lazy=False):
if 'div_target_monthly' in fields:
fields.remove('div_target_monthly')
return super(report_sales_weekly, self).read_group(cr, uid, domain, fields, groupby, offset=offset, limit=limit, context=context, orderby=orderby, lazy=lazy)
# As stated in the comments, you can also not put offset=offset etc. but just the variables offset, limit, ... Thanks #Kenly
# Also, why this line ?
# report_sales_weekly()
