From 6127608cae729b5c8bf20b92d8af3d591cc2034f Mon Sep 17 00:00:00 2001 From: Simon Lejeune Date: Sat, 11 May 2019 15:44:16 +0000 Subject: [PATCH] [REF] stock_account: standard cost method with valuation layers Valuation of standard move: We introduce _create_in_svl and _create_out_svl and call these method in _action_done only on the standard move, the other valuation methods still use the old code. We hijack _account_entry_move to create journal entries anyway for the valuation layer with a minimal diff. Helpers for the valuation layers creation are added on the product because we will need to create similar layer without stock move later on when we'll implement changes of cost method. We also make a first implementation of the edition in the past to make some tests pass, it will be completed with other cost method implementation Change of standard price: Before this commit, the wizard to change the standard price was only displayed in perpetual, because it was used to create accountign entries. We also use this wizard in manual now, because we want to create a stock valuation layer. Fortunetaly, the accounting fields of this wizard are not required if the product has a manual valuation. And the new method is private. We adapt the existing tests as well as we can and include the start of a new battery of tests: test_stockvaluationlayer.py task-1875873 --- addons/stock_account/models/product.py | 119 +++++++++++ addons/stock_account/models/stock_move.py | 81 ++++++- .../stock_account/models/stock_move_line.py | 44 +++- addons/stock_account/tests/__init__.py | 1 + .../tests/test_stockvaluation.py | 144 +++++-------- .../tests/test_stockvaluationlayer.py | 202 ++++++++++++++++++ addons/stock_account/views/product_views.xml | 8 +- .../wizard/stock_change_standard_price.py | 2 +- 8 files changed, 505 insertions(+), 96 deletions(-) create mode 100644 addons/stock_account/tests/test_stockvaluationlayer.py diff --git a/addons/stock_account/models/product.py b/addons/stock_account/models/product.py index b3c57626f97..aee06a78892 100644 --- a/addons/stock_account/models/product.py +++ b/addons/stock_account/models/product.py @@ -80,6 +80,125 @@ class ProductProduct(models.Model): product.value_svl = group['value'] product.quantity_svl = group['quantity'] + # ------------------------------------------------------------------------- + # SVL creation helpers + # ------------------------------------------------------------------------- + def _prepare_in_svl_vals(self, quantity, unit_cost): + """Prepare the values for a stock valuation layer created by a receipt. + + :param quantity: the quantity to value, expressed in `self.uom_id` + :param unit_cost: the unit cost to value `quantity` + :return: values to use in a call to create + :rtype: dict + """ + self.ensure_one() + vals = { + 'product_id': self.id, + 'value': unit_cost * quantity, + 'unit_cost': unit_cost, + 'quantity': quantity, + } + return vals + + def _prepare_out_svl_vals(self, quantity): + """Prepare the values for a stock valuation layer created by a delivery. + + :param quantity: the quantity to value, expressed in `self.uom_id` + :return: values to use in a call to create + :rtype: dict + """ + self.ensure_one() + # Quantity is negative for out valuation layers. + quantity = -1 * quantity + vals = { + 'product_id' : self.id, + 'value': quantity * self.standard_price, + 'unit_cost': self.standard_price, + 'quantity': quantity, + } + return vals + + def _change_standard_price(self, new_price, counterpart_account_id=False): + """Helper to create the stock valuation layers and the account moves + after an update of standard price. + + :param new_price: new standard price + """ + # Handle stock valuation layers. + svl_vals_list = [] + company_id = self.env.user.company_id + for product in self: + if product.cost_method not in ('standard', 'average'): + continue + if float_is_zero(product.quantity_svl, precision_rounding=product.uom_id.rounding): + continue + diff = new_price - product.standard_price + value = company_id.currency_id.round(product.quantity_svl * diff) + if company_id.currency_id.is_zero(value): + continue + + svl_vals = { + 'company_id': company_id.id, + 'product_id': product.id, + 'description': _('Product value manually modified (from %s to %s)') % (product.standard_price, new_price), + 'value': value, + 'quantity': 0, + } + svl_vals_list.append(svl_vals) + stock_valuation_layers = self.env['stock.valuation.layer'].create(svl_vals_list) + + # Handle account moves. + product_accounts = {product.id: product.product_tmpl_id.get_product_accounts() for product in self} + am_vals_list = [] + for stock_valuation_layer in stock_valuation_layers: + product = stock_valuation_layer.product_id + value = stock_valuation_layer.value + + if product.valuation != 'real_time': + continue + + # Sanity check. + if counterpart_account_id is False: + raise UserError(_('You must set a counterpart account.')) + if not product_accounts[product.id].get('stock_valuation'): + raise UserError(_('You don\'t have any stock valuation account defined on your product category.
