Sambil testing data di Odoo, saya mendapatkan galat seperti ini :

File "/usr/lib/python3/dist-packages/odoo/models.py", line 4371, in ensure_one
raise ValueError("Expected singleton: %s" % self)
ValueError: Expected singleton: stock.move(32898, 32899, 32900)

File "/usr/lib/python3/dist-packages/odoo/models.py", line 4371, in ensure_one

raise ValueError("Expected singleton: %s" % self)

ValueError: Expected singleton: stock.move(32898, 32899, 32900)

Solusi:

Mencoba dengan iterasi for loop

for record in self:
   if record.doctype is 
   # First check if entered value is valid

for record in self:

if record.doctype is

# First check if entered value is valid
