in my model.py, I have:

totFee = fields.Float(compute='_compute_totFee')


@api.depends('field1','field2')
def _compute_totFee(self): 
for rec in self: 
self.totFee = 44

I get an error message:

ERROR crc openerp.http: Exception during JSON request handling.

how would I write that function?

TIA



Hi Yves, Is your function above the fields.Float that has the compute field? If the function is under the fields.Float move it above the fields.Float. Regards, Yenthe

check the indentation of method, it should be inside the class

Hello, 

- without the complete file it is difficult to help you.

on note:


@api.depends('field1','field2')def _compute_totFee(self):      
for rec in self: 
self.totFee = 44

should be:

@api.depends('field1','field2')def _compute_totFee(self):      
for rec in self:
rec.totFee = 44
