Question

如何阻止用户输入已存在的员工，如下图所示：

因此，当用户尝试输入已存在的同一员工时，它将引发警告或错误消息

我已经完成了这个功能：

class overtime(models.Model):
    _name = 'overtime.overtime'

    employee_ids = fields.One2many('overtime.overtime_details', 'overtime_id', string="Employee", readonly=True, states={'draft': [('readonly', False)]})

class overtime_details(models.Model):
    _name='overtime.overtime_details'

     @api.multi
     @api.constrains('employee_id')
     @api.onchange('employee_id')
     def prevent_duplicate(self):
        #import pdb;pdb.set_trace()
        if self.employee_id:
            bruh = self.search([])
            for empy in bruh:
                if self.employee_id.id == empy.employee_id.id:
                    raise osv.except_osv(_('Error!'),_('You Cant Enter Same Employee in One Overtime Request!'))

     nik = fields.Char('NIK', size=250, required=True)
     overtime_id = fields.Many2one('overtime.overtime', string="Overtime", ondelete='cascade')
     job_id = fields.Many2one('hr.job', string="Position", readonly=True)
     employee_id = fields.Many2one('hr.employee', "Employee", required=True, select=True, copy=False
                    , domain="[('department_id', '=', parent.department_id)]")
     ovrtm = fields.Float(compute=attd_check, string='Overtime Hour(s)')
     ttalmtp = fields.Float(compute=overtype_count, string='Total Multiplier')

但它会循环我保存在数据库中的每条记录，所以我需要帮助我应该怎么做，如果我想循环记录我在该会话中输入？我正在研究odoo v8

这里我通过方法或捕获约束数据库错误给出了可能性：

class overtime(models.Model):
    _name = 'overtime.overtime'

    employee_ids = fields.One2many('overtime.overtime_details',
                    'overtime_id', string="Employee",
                    readonly=True, states={'draft': [('readonly', False)]})

    #no need for multi because by default they are multi
    @api.onechange('employee_ids')
    @api.constrains('employee_ids') 
    def prevent_dupe(self): 
        # what you did here is wrong 
        # it will always give you = 12 because you are
        # computing the len of string 'employee_ids' not 
        # the number of record in the one2many field
        # o2m_size = len('employee_ids') 
        o2m_size = len(self.employee_ids) 
        employee_count = len(self.employee_ids.mapped('employee_id'))
        if o2m_size != employee_count:
            raise exceptions.ValidationError(_("Employee already exist!"))


class overtime_details(models.Model):
    _name='overtime.overtime_details'

     nik = fields.Char('NIK', size=250, required=True)
     overtime_id = fields.Many2one('overtime.overtime', string="Overtime", ondelete='cascade')
     job_id = fields.Many2one('hr.job', string="Position", readonly=True)
     employee_id = fields.Many2one('hr.employee', "Employee", required=True, select=True, copy=False
                    , domain="[('department_id', '=', parent.department_id)]")
     ovrtm = fields.Float(compute=attd_check, string='Overtime Hour(s)')
     ttalmtp = fields.Float(compute=overtype_count, string='Total Multiplier')

     # if you want to prevent duplicated 
     # and constrains for that if the method didn't work for you
     _sql_constraints = [('unique_imployee_overtime', 'unique(overtime_id,employee_id)',
                                _(" Deplicated employee in overtime ")), ]

Answer 2

您可以使用插入的'id'作为参数执行'browse'，而不是'search'，并检查获得记录集，如果它不为空则引发异常。

这样的事情：
