从费用创建费用报告

方法： action_submit_expense

def action_submit_expenses(self):
    context_vals = self._get_default_expense_sheet_values()
    if len(context_vals) > 1:
        sheets = self.env['hr.expense.sheet'].create(context_vals)
        return {
            'name': _('New Expense Reports'),
            'type': 'ir.actions.act_window',
            'views': [[False, "list"], [False, "form"]],
            'res_model': 'hr.expense.sheet',
            'domain': [('id', 'in', sheets.ids)],
            'context': self.env.context,
        }
    else:
        context_vals_def = {}
        for key in context_vals[0]:
            context_vals_def['default_' + key] = context_vals[0][key]
        return {
            'name': _('New Expense Report'),
            'type': 'ir.actions.act_window',
            'views': [[False, "form"]],
            'res_model': 'hr.expense.sheet',
            'target': 'current',
            'context': context_vals_def,
        }

内部使用 _get_default_expense_sheet_values方法获取默认值

从费用报告创建账单

方法： action_sheet_move_create

def action_sheet_move_create(self):
    samples = self.mapped('expense_line_ids.sample')
    if samples.count(True):
        if samples.count(False):
            raise UserError(_("You can't mix sample expenses and regular ones"))
        self.write({'state': 'post'})
        return

    if any(sheet.state != 'approve' for sheet in self):
        raise UserError(_("You can only generate accounting entry for approved expense(s)."))

    if any(not sheet.journal_id for sheet in self):
        raise UserError(_("Specify expense journal to generate accounting entries."))

    if not self.employee_id.sudo().address_home_id:
        raise UserError(_("The private address of the employee is required to post the expense report. Please add it on the employee form."))

    expense_line_ids = self.mapped('expense_line_ids')\
        .filtered(lambda r: not float_is_zero(r.total_amount, precision_rounding=(r.currency_id or self.env.company.currency_id).rounding))
    res = expense_line_ids.with_context(clean_context(self.env.context)).action_move_create()

    paid_expenses_company = self.filtered(lambda m: m.payment_mode == 'company_account')
    paid_expenses_company.write({'state': 'done', 'amount_residual': 0.0, 'payment_state': 'paid'})

    paid_expenses_employee = self - paid_expenses_company
    paid_expenses_employee.write({'state': 'post'})

    self.activity_update()
    return res

sheet中准备bill数据的方法：_prepare_bill_vals

def _prepare_bill_vals(self):
    self.ensure_one()
    return {
        **self._prepare_move_vals(),
        # force the name to the default value, to avoid an eventual 'default_name' in the context
        # to set it to '' which cause no number to be given to the account.move when posted.
        'journal_id': self.journal_id.id,
        'move_type': 'in_invoice',
        'partner_id': self.employee_id.sudo().address_home_id.commercial_partner_id.id,
        'currency_id': self.currency_id.id,
        'line_ids':[Command.create(expense._prepare_move_line_vals()) for expense in self.expense_line_ids],
    }

准备move的方法是_prepare_move_vals

费用中准备账单明细行数据的方法： _prepare_move_line_vals

def _prepare_move_line_vals(self):
    self.ensure_one()
    account = self.account_id
    if not account:
        # We need to do this as the installation process may delete the original account and it doesn't recompute properly after.
        # This forces the default values if none is found
        if self.product_id:
            account = self.product_id.product_tmpl_id._get_product_accounts()['expense']
        else:
            account = self.env['ir.property']._get('property_account_expense_categ_id', 'product.category')

    return {
        'name': self.employee_id.name + ': ' + self.name.split('\n')[0][:64],
        'account_id': account.id,
        'quantity': self.quantity or 1,
        'price_unit': self.unit_amount,
        'product_id': self.product_id.id,
        'product_uom_id': self.product_uom_id.id,
        'analytic_distribution': self.analytic_distribution,
        'expense_id': self.id,
        'partner_id': False if self.payment_mode == 'company_account' else self.employee_id.sudo().address_home_id.commercial_partner_id.id,
        'tax_ids': [Command.set(self.tax_ids.ids)],
    }

• 从费用报告创建账单的时候，使用的是员工的联系人地址(私人地址)关联的商业实体(通常为上级公司)。
