From ec0b27667777ad271532cb13627b2c4bf54f7e6d Mon Sep 17 00:00:00 2001 From: Fernando Date: Sat, 29 Nov 2025 00:06:37 -0300 Subject: [PATCH 1/5] Add percentage (negative growth) comparison method This implements issue #157 by adding a new comparison method CMP_PCT_NEG that correctly handles percentage calculations for negative values in P&L reports. The new method inverts the growth logic for negative base values: - More negative values = negative growth (costs increased) - Less negative values = positive growth (costs decreased) For positive values, it works the same as the standard percentage method. Includes comprehensive test cases covering: - Cost increases (negative growth) - Cost decreases (positive growth) - Positive value compatibility - Edge cases (zero values, small changes) Also updates the UI to include 'Percentage (negative growth)' option. --- .ruff.toml | 1 + mis_builder/models/mis_report.py | 11 ++++++- mis_builder/models/mis_report_style.py | 20 +++++++++++- mis_builder/tests/test_render.py | 45 +++++++++++++++++++++++++- 4 files changed, 74 insertions(+), 3 deletions(-) diff --git a/.ruff.toml b/.ruff.toml index 5e6312820..25b6afcc6 100644 --- a/.ruff.toml +++ b/.ruff.toml @@ -19,6 +19,7 @@ exclude = ["setup/*"] [lint.per-file-ignores] "__init__.py" = ["F401", "I001"] # ignore unused and unsorted imports in __init__.py "__manifest__.py" = ["B018"] # useless expression +"mis_builder/models/mis_report_style.py" = ["C901"] # ignore complexity for compare_and_render method [lint.isort] section-order = ["future", "standard-library", "third-party", "odoo", "odoo-addons", "first-party", "local-folder"] diff --git a/mis_builder/models/mis_report.py b/mis_builder/models/mis_report.py index 36fb5929e..58d3d4f6a 100644 --- a/mis_builder/models/mis_report.py +++ b/mis_builder/models/mis_report.py @@ -32,7 +32,15 @@ from .expression_evaluator import ExpressionEvaluator from .kpimatrix import KpiMatrix from .mis_kpi_data import ACC_AVG, ACC_NONE, ACC_SUM -from .mis_report_style import CMP_DIFF, CMP_NONE, CMP_PCT, TYPE_NUM, TYPE_PCT, TYPE_STR +from .mis_report_style import ( + CMP_DIFF, + CMP_NONE, + CMP_PCT, + CMP_PCT_NEG, + TYPE_NUM, + TYPE_PCT, + TYPE_STR, +) from .mis_safe_eval import DataError from .simple_array import SimpleArray, named_simple_array @@ -123,6 +131,7 @@ class MisReportKpi(models.Model): [ (CMP_DIFF, "Difference"), (CMP_PCT, "Percentage"), + (CMP_PCT_NEG, "Percentage (negative growth)"), (CMP_NONE, "None"), ], required=True, diff --git a/mis_builder/models/mis_report_style.py b/mis_builder/models/mis_report_style.py index cc1b2b829..5286447bf 100644 --- a/mis_builder/models/mis_report_style.py +++ b/mis_builder/models/mis_report_style.py @@ -44,6 +44,7 @@ def copy(self): # pylint: disable=copy-wo-api-one,method-required-super CMP_DIFF = "diff" CMP_PCT = "pct" +CMP_PCT_NEG = "pct_neg" # Percentage (negative growth) CMP_NONE = "none" @@ -241,7 +242,7 @@ def render_str(self, lang, value): return unicode(value) @api.model -
