如何从odoo 9中的数据库中获取数据

Question

我有一段获取数据的代码，但是没用

py文件

 class group_js(osv.osv):
    _name = "group_js"
    _description = "Group JS"

    _columns={
       'id': fields.integer('ID', readonly=True),
       'name': fields.char('Purpose', required=True, select=1),
       'js' : fields.text('Javascript',required = True , index=True,store=True),
       'active' : fields.boolean('Active'),
       'group_id': fields.many2many('res.groups', 'js_group_rel', 'js_group_id', 'group_id', string='Groups'),
    }
   _sql_constraints = [
    ('name_uniq', 'unique (name)', 'The name of the Javascript available , You must change your javascript name or check the javascript code may available !!!')
   ]

   def get_record(self,cr,uid,context=None):
     get_obj=self.pool.get('group_js')
     user_ids = get_obj.browse(cr, uid,uid,[])
     return user_ids.to_JSON()

  def to_JSON(self,cr,context=None):
     return json.dumps(self, default=lambda o: o.__dict__, sort_keys=True, indent=4)

Answer 1

Browse take cursor, user ,ids , context

对于 id，您首先 在模型中搜索 使用空白域 [].

试试这个方法：

   def get_record(self,cursor,user,context=None):
     get_obj=self.pool.get('group_js')
     domain=[]
     ids = get_obj.search(cursor, user,domain)
     user_ids = get_obj.browse(cursor, user,ids,context)
     return user_ids.to_JSON()

或者这样

   def get_record(self,cursor,user,context=None):
     get_obj=self.pool.get('group_js')
     domain=[]
     ids = get_obj.search(cursor, user,domain)
     user_ids = get_obj.read(cursor, user,ids,[],context)
     return user_ids

已编辑：关于如何获取组名和 id

因为 group_id 是 many2many 字段，所以在这种情况下，您将有 browse 如下记录并更新组 group_id:

group_obj = self.pool.get('res.groups')
def get_id_name(group_id):
    res =group_obj.browse(cursor, user,group_id)
    return res.id,res.name
user_ids[0]['group_id']=map(lambda group_id:get_id_name(group_id),user_ids[0]['group_id'])

现在该方法将如下所示：

  def get_record(self,cursor,user,context=None):
    get_obj=self.pool.get('group_js')
    domain=[]
    ids = get_obj.search(cursor, user,domain)
    user_ids = get_obj.read(cursor, user,ids,[],context)
    group_obj = self.pool.get('res.groups')
    def get_id_name(group_id):
        res =group_obj.browse(cursor, user,group_id)
        return res.id,res.name
    user_ids[0]['group_id']=map(lambda group_id:get_id_name(group_id),user_ids[0]['group_id'])
    return user_ids
