I want to access all files from many2many field. I don't want to save the files in the db, thats why is store=False

assets_uploader = fields.Many2many(comodel_name='ir.attachment', string='Assets upload', attachment=True, store=False)

<button string="Upload"  type="object" name="upload_asset" context="{'assets_uploader': assets_uploader}" />

def upload_asset(self):      

        for file in self._context.get('assets_uploader'):

            print(file)
