Use ORM methods, to get the required data? - odoo

Question

I need to get the value of field in a tree view of the fields_view_get method and a
I use ORM methods to achieve this. my code :
class res_partner(osv.osv):
_inherit = 'res.partner'
def fields_view_get(self, cr, uid, view_id=None, view_type='form', context=None, toolbar=False, submenu=False):
if context is None:
context = {}
partner_obj = self.pool.get('res.partner')
ids_partner = partner_obj.search(cr, uid, [], context=context)
partner_name = partner_obj.browse(cr, uid, ids_partner, context=context)
element = partner_obj.browse(cr,uid,ids_partner[0]).numcte
res = super(res_partner,self).fields_view_get(cr, uid, view_id=view_id, view_type=view_type, context=context, toolbar=toolbar, submenu=submenu)
newcte=test_name.numcte
doc = etree.XML(res['arch'])
if view_type == 'tree':
for node in doc.xpath("//field[#name='numcte']"):
node.set('string', 'numcte')
for node in doc.xpath("//button[#name='icono']"):
node.set('icon', newcte)
res['arch'] = etree.tostring(doc)
return res
_columns = {
'numcte': fields.text('numero cliente'),
}
res_partner()
My problem is when I, use for instance :
element = partner_obj.browse(cr,uid,ids_partner[0]).numcte
It returns me the value of the field that I want, but in the treeView is the same for each row, like this A001, A001, A001, in instead of A001, A002, A003.
in this case ids_partner[0], How can I make this number to be dynamic and changing for each row ?
Or in the case that use this:
my_data = partner_obj.read(cr, uid, ids_partner, ["numcte"], context=context)
returns me the tuple like this:
[{'numcte': u'A001', 'id': 3}, {'numcte': u'A002', 'id': 2}, {'numcte': u'A003', 'id': 4}]
[{'numcte': u'A001', 'id': 3}, {'numcte': u'A002', 'id': 2}, {'numcte': u'A003', 'id': 4}]
[{'numcte': u'A001', 'id': 3}, {'numcte': u'A002', 'id': 2}, {'numcte': u'A003', 'id': 4}]
one for each row
How can I get the value of the field that I want for the correct row. ?
thank you all for your time, I been a while in this so any help is usefull.

Answer 1

fields_view_get is provided to allow you to change/create the XML that defines the view, not the data.
What you need to do in fields_view_get is drop your field onto the view. However, overriding fields_view_get is only done in very unusual cases where you need the view to by dynamic in a way that can't be achieved easily with attrs and states in the XML view.
The usual pattern is to create a view in XML that extends the partner tree view and adds your field in the correct place using an XPATH expression. If your field is a new field, you will need to also need to create a new model that inherits the res_partner model and add your new field in _columns.
