Hi CorTex IT Solutions Ltd
thanks for your answer
this code is exactly what i wrote it but unfortunately it is not working
ok my code is like this :
class AccountMoveLine(models.Model):
_name = "account.move.line"
_inherit = "account.move.line"
einv_amount_discount = fields.Monetary(string="Amount discount", compute="_compute_amount_discount", store='True',
help="")
einv_amount_tax = fields.Monetary(string="Amount tax", compute="_compute_amount_tax", store='True', help="")
# price_sup_total
einv_price_subtotal = fields.Monetary(string='sub total', compute='_compute_price_total')
# price_to_tal
einv_price_total = fields.Monetary(string='total', compute='_price_to_tal')
dayes = fields.Char(string="Days", store=True)
date_s = fields.Date(string="Start D", store='True')
date_e = fields.Date(string="End D", store='True')
date_difference = fields.Integer(string="dayes", compute="_compute_dayes", default=1)
invoice_line_ids = fields.Many2one('account.move')
@api.depends('date_s', 'date_e', 'date_difference')
def _compute_dayes(self):
for r in self:
if r.date_s and r.date_e:
date_ss = datetime.strptime(str(r.date_s), '%Y-%m-%d').date()
date_ee = datetime.strptime(str(r.date_e), '%Y-%m-%d').date()
cek_hasil = (date_ee - date_ss).days
r.date_difference = (int(cek_hasil)) # / 100000
# cek_day = r.sub('[^0-9]', '', str(cek_hasil))
@api.depends('price_unit', 'quantity', 'date_difference', 'invoice_line_ids')
def _compute_price_total(self):
for line in self:
for res in line.invoice_line_ids:
line.einv_price_subtotal = line.price_unit * res.quantity * line.date_difference
@api.depends('discount', 'quantity', 'price_unit')
def _compute_amount_discount(self):
for r in self:
r.einv_amount_discount = r.quantity * r.price_unit * (r.discount / 100)
@api.depends('tax_ids', 'discount', 'quantity', 'price_unit', 'einv_price_subtotal')
def _compute_amount_tax(self):
for r in self:
r.einv_amount_tax = sum(r.einv_price_subtotal * (tax.amount / 100) for tax in r.tax_ids)
@api.depends('einv_amount_tax', 'einv_price_subtotal', 'invoice_line_ids')
def _price_to_tal(self):
for line in self:
for res in line.invoice_line_ids:
line.einv_price_total = line.einv_price_subtotal + line.einv_amount_tax
and after that i simple have a report print the invoice
and it is get me this error

ValueError: Compute method failed to assign account.move.line(55,).einv_price_subtotal
Template: einv_sa.inv_lines
Path: /t/table/tbody/tr/td[7]/span
Node: so any help pleas
If the store equal to True then the code will run the first time when you install the module and then whenever there is a change in any of the three fields mentioned in the depends the compute method will be called.
Try to set the store=false and upgrade the module.
If you have a compute field in your model and you set store=True for the field, the field value will not get recomputed if proper depends is not given for the compute function.
Please post your code here
Replace the below line as you are set Store=True and its should be store=True. Also you are set store=True for not computed fields.
compute="_compute_amount_discount", store=True,help="")
einv_amount_tax = fields.Monetary(string="Amount tax", compute="_compute_amount_tax", store=True, help="")
dayes = fields.Char(string="Days")
date_s = fields.Date(string="Start D")
date_e = fields.Date(string="End D")
There below error is self explained:
Compute method failed to assign account.move.line(55,).einv_price_subtotal
There is no invoice_line_ids in account.move.line so your method should be
@api.depends('price_unit', 'quantity', 'date_difference',)
def _compute_price_total(self):
for line in self:
line.einv_price_subtotal = line.price_unit * line.quantity * line.date_difference
Thanks man you are the best
hi thanks man you code is working greatly but win i aply it i get error in the tax felds
einv_amount_tax = fields.Monetary(string="Amount tax", compute="_compute_amount_tax", help="")
@api.depends('tax_ids', 'discount', 'quantity', 'price_unit', 'einv_price_subtotal')
def _compute_amount_tax(self):
for r in self:
r.einv_amount_tax = sum(r.einv_price_subtotal * (tax.amount / 100) for tax in r.tax_ids)
this is my field and my method
and it is give me THE SAME error
File "C:\Program Files (x86)\odoo14\server\odoo\addons\einv_sa\model\account_move.py", line 193, in _compute_subtotal

File "C:\Program Files (x86)\odoo14\server\odoo\fields.py", line 1028, in __get__
raise ValueError("Compute method failed to assign %s.%s" % (record, self.name))
Exception
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "C:\Program Files (x86)\odoo14\server\odoo\http.py", line 640, in _handle_exception
return super(JsonRequest, self)._handle_exception(exception)

raise exception.with_traceback(None) from new_cause
ValueError: Compute method failed to assign account.move.line(100,).date_difference
and this error shwon if i chose a tax id in the tax feld in the line
The issue is the below:
ValueError: Compute method failed to assign account.move.line(100,).date_difference
The date_difference computed method is not correct. try to use log or print the value to check if it's calculated correct value or not
You can define the subtotal as computed field and you can choose to store it in DB or not by adding attribute store=True.
Define subtotal field:
subtotal = fields.Float(string='SubTotal',compute='_compute_subtotal', store=True)
Then define computed method:
@api.depends('price_unit',' quantity',' date_deffrence')
def _compute_subtotal(self)
for line in self:
line.subtotal = line.price_unit * line.quantity * line.date_deffrence
Note if the date_deffrence is zero the subtotal will be zero.
