Hi,

You might be calling some function as compute of the field and you might not define the function which is called, Check whether the _read_group_stage_ids has called in compute attribute of a filed and see. Or just search for the _read_group_stage_ids in your custom code.


Thanks

Thank you So much i fix the problem , i have one another question about how to get date at this moment is there any function in odoo like date.now() ior something like that beacause i have a compute field and i need it to make dvision between aquisition date wich a field that i have and date.now() 

Example : 

date_now= ???? function to get date .now 

Duree_ct = ((aquisition_date - date_now).days / 30)
