I added a Tax Description/Account line item in an invoice. I added the field to the tree view by enabling developer mode, editing the view, and adding an entry in the XML for the line item. This is not a module I developed. I'd like to display the sum of the amounts, but no matter what I try I only seem able to display the number of line items as shown in this screenshot: dl.dropboxusercontent.com/u/174789/screenshot.png. In this screenshot there is only one line item, but there could be more.
How can I display the total of the line item values instead of the number of records in the database? Thanks.
Edit: Here are two more screenshots. I created a one2many field in the admin dashboard: dl.dropboxusercontent.com/u/174789/newfield.png. This is the line item entry I made in the invoice: dl.dropboxusercontent.com/u/174789/invoice.png. The field is included in the tree view like: <field name="x_FlourTaxAmount" sum="Flour Tax Total"/>. I did not create a module. I did not add a .py or .xml.
Edit: This is what we came up with. Now that we understand the solution a little better some variables need to be renamed, otherwise this works.
from openerp.osv import fields, osv
class AAA(osv.osv):
_inherit = 'account.invoice'
def get_tax_total(self, cr, uid, ids, field, arg, context=None, line_name=None):
#~ import ipdb;ipdb.set_trace();
res = {}
for order in self.browse(cr, uid, ids, context=context):
res[order.id] = {
'flour_tax_total': 0,
}
val = 0
for line in order.flour_tax:
if line.name.startswith(line_name):
val += line.tax_amount
res[order.id] = val
return res
def get_flour_tax_total(*args, **kwargs):
kwargs["line_name"] = "Harina"
return get_tax_total(*args, **kwargs)
_columns = {
'flour_tax': fields.one2many('account.invoice.tax', 'invoice_id', 'Flour Tax Amount'),
'flour_tax_total': fields.function(get_flour_tax_total, type='float', string='Flour Tax Total'),
}
_defaults ={
'flour_tax': 13,
'flour_tax_total': 42,
}
AAA()
In the screenshot, I can see the amount
5000.00
on top and at very bottom. So at the very bottom amount is total of all the values of fieldSubtotal
. You can do it same for line item values but it should be type of float instead of character. Then you can achieve total of line item at the very bottom.
