python 2.7 - Odoo Inherit - adding fields -


i testing odoo 9 , and trying figure out inheritance. below code should field jason_test2,total_amount_invoice , total_balance_invoice added res.partner table. not adding them , not know if should be.

from openerp.osv import osv, fields openerp.tools.translate import _ openerp import fields, models, api, exceptions, _ class respartner(models.model):   _inherit = 'res.partner' def _get_total_amount_invoice(self):     res = {}     partner in self:         invoice_obj = self.env['account.invoice']         invoice_ids = invoice_obj.search([('partner_id', '=', partner.id)])         amount_total = 0         invoice in invoice_ids:             amount_total += invoice.amount_total         res.update({'total_amount_invoice': amount_total})   def _get_total_balance_invoice(self):     res = {}     partner in self:         invoice_obj = self.env['account.invoice']         invoice_ids = invoice_obj.search([('partner_id', '=', partner.id)])         balance_total = 0         invoice in invoice_ids:             balance_total += invoice.residual         res.update({'total_balance_invoice': balance_total})   jason_test2 = fields.char("jason2")  total_amount_invoice = fields.monetary(string='amount total', type='float',                                        readonly=true, compute='_get_total_amount_invoice') total_balance_invoice = fields.monetary(string='balance total', type='float',                                         readonly=true, compute='_get_total_balance_invoice')

unless question formatting issue, body of class definition should indented, otherwise not part of class @ all.

class respartner(models.model):      _inherit = 'res.partner'     def _get_total_amount_invoice(self):         res = {}         partner in self:             invoice_obj = self.env['account.invoice']             invoice_ids = invoice_obj.search([('partner_id', '=', partner.id)])             amount_total = 0             invoice in invoice_ids:                 amount_total += invoice.amount_total             res.update({'total_amount_invoice': amount_total})       def _get_total_balance_invoice(self):         res = {}         partner in self:             invoice_obj = self.env['account.invoice']             invoice_ids = invoice_obj.search([('partner_id', '=', partner.id)])             balance_total = 0             invoice in invoice_ids:                 balance_total += invoice.residual             res.update({'total_balance_invoice': balance_total})       jason_test2 = fields.char("jason2")      total_amount_invoice = fields.monetary(string='amount total', type='float',                                            readonly=true, compute='_get_total_amount_invoice')     total_balance_invoice = fields.monetary(string='balance total', type='float',                                             readonly=true, compute='_get_total_balance_invoice')

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...

ios - Change Storyboard View using Seague -
