odoo12常用的方法

#自定义显示名称
def name_get(self):
    result = []
    for order in self:
        rec_name = "%s(%s)"%(record.name,record.date_done)
        result.append((record.id, rec_name))
    return result


# 新添加函数name_search
@api.model
def name_search(self, name=‘‘, args=None, operator=‘ilike‘, limit=100):
    if not args:
        args = []
        products = []
    if name:
        positive_operators = [‘=‘, ‘ilike‘, ‘=ilike‘, ‘like‘, ‘=like‘]
        products = self.env[‘product.product‘]
        if operator in positive_operators:
            products = self.search([(‘name‘, ‘ilike‘, name)] + args, limit=limit)
            if not products:
                products = self.search([(‘size‘, ‘ilike‘, name)] + args, limit=limit)
            if not products:
                products = self.search([(‘material‘, ‘ilike‘, name)] + args, limit=limit)
    else:
        products = self.search(args, limit=limit)
    return products.name_get()






#添加约束
from odoo.exceptions import ValidationError
@api.constrains(‘age‘)
def _check_something(self):
    for record in self:
        if record.age > 20:
            raise ValidationError("Your record is too old: %s" % record.age)

    # all records passed the test, don‘t return anything  

#更新时间
@api.multi
def change_updatetime(self):
    for order in self:
      order.update_time=fields.Datetime.now()

在SQL语句里或ORM里  记录集要用tuple  不能用list
search([(‘id‘,‘in‘,tuple(ids)])


调用mapped获取员工名字
return employee_ids.mapped(‘name‘)

#获取用户组：self.user_has_groups(‘base.group_no_one‘)


看板默认分组当无此类型当值时也默认出现在看板里
#对于odoo12来说  group_expand=‘‘   对于selection类型
state = fields.Selection([(‘a‘, "A"), (‘b‘, "B"),(‘c‘, "C"), (‘d‘, "D")], group_expand=‘_expand_states‘)

def _expand_states(self, states, domain, order):
    # return all possible states, in order
    return [key for key, val in type(self).state.selection]






#对于odoo12来说  group_expand=‘‘   对于many2one类型
stage_id = fields.Many2one(‘crm.stage‘, string=‘Stage‘, ondelete=‘restrict‘, track_visibility=‘onchange‘, index=True,
                           domain="[‘|‘, (‘team_id‘, ‘=‘, False), (‘team_id‘, ‘=‘, team_id)]",
                           group_expand=‘_read_group_stage_ids‘, default=lambda self: self._default_stage_id())
@api.model
def _read_group_stage_ids(self, stages, domain, order):
    """ Read group customization in order to display all the stages in the
        kanban view, even if they are empty
    """
    stage_ids = stages._search([], order=order, access_rights_uid=SUPERUSER_ID)
    return stages.browse(stage_ids)



#以超级用户身份创建记录
rent_as_superuser = self.env[‘library.book‘].sudo()

rent_as_superuser.create(vals)


#获取当前用户对于的员工

employee = self.env.user.employee_ids[0]  #对象

employee.id

employee.name
