v1.4.0

New Features

• Dynamic Model support — generate reports from any database table without defining a Django model.
  New get_dynamic_model(table_name, database, schema) utility introspects a live table and returns a
  fully usable (unmanaged) Django model. Supports 20+ field types and PostgreSQL schemas
  (schema parameter generates "schema"."table_name" as the db table).
  Models are cached after first introspection.
• table_name attribute on ReportGenerator and ReportView — shorthand for using a dynamic model.
  Setting table_name = "my_table" is equivalent to setting report_model = get_dynamic_model("my_table").
  Column validation is deferred to request time for table_name-based views so imports do not trigger
  database access.
• Pre-computed crosstab reports — new crosstab_precomputed = True flag on ReportGenerator
  switches from live aggregation to reading existing column values and pivoting them.
  Use crosstab_columns to name the value columns and crosstab_field to identify the pivot field.
  Distinct values for crosstab_field are auto-discovered from the database if crosstab_ids is not set.
  Intended for materialized views, data-warehouse fact tables, and pre-aggregated ETL outputs.
• Print / HTML export — new PrintHTMLExport class renders a clean, RTL-aware, print-ready HTML
  page and triggers window.print() automatically. Enabled by default on all ReportView subclasses
  via the new print_export_class attribute. The print export button opens in a new browser tab.
  Templates are split into print_report.html, print_report_header.html, print_report_footer.html,
  and print_report_controls.html for easy overriding.
• Arabic (ar) and German (de) translations added.

Improvements

• Static asset path resolution — template tags now consistently apply Django's static() to any
  relative URL in settings (jQuery URL, chart engine JS files, Font Awesome CSS URL). The
  slick_reporting_settings JSON block written to the page also contains fully resolved static URLs,
  ensuring correct paths with ManifestStaticFilesStorage or CDN-backed storages.
• Export action metadata — get_export_actions() now includes a new_window flag per action;
  the JS export handler opens a new tab when the flag is set, used by the print export.
• Report form extracted — the filter form markup is now in its own report_form.html template
  (included by report.html) making it easier to override just the form section.
• Select2 removed from core assets — Select2 was a demo-only dependency that made it into the default
  SLICK_REPORTING_SETTINGS["MEDIA"] JS/CSS lists and was auto-initialised in report_loader.js.
  It is now removed from the library defaults; demo project configures it separately.
• fkeys_filter_func_hook — new static method on ReportViewBase that receives the dict of
  detected foreign-key fields before the filter form is built. Override it to exclude or rename fields
  (e.g. remove internal FK columns such as polymorphic_ctype_id).
• Chart error recovery — chart rendering errors are now caught in report_loader.js and displayed
  as an inline message instead of silently breaking the rest of the page.

Bug Fixes

• Fix crosstab_compute_remainder class-level attribute being ignored; the value was always read from
  the request instead of falling back to the class default.

Chart Engine Fixes

• Update Highcharts wrapper to use the modern Highcharts.chart() API (v11+), replacing the removed
  jQuery plugin syntax. Switch default Highcharts CDN to jsDelivr (cdn.jsdelivr.net/npm/highcharts@11).
• Fix Chart.js wrapper: corrected inverted is_time_series check; update to Chart.js v3/v4 API
  (plugins.title, plugins.tooltip, scales.y / scales.x).
• Add crosstab support to the Chart.js wrapper.
• Fix Chart.js area chart type to render as line with fill: true.
• Fix Chart.js pie chart on time-series reports: automatically enables plot_total.
• Fix Chart.js pie chart sizing with aspectRatio: 2.
• Fix Chart.js chart cache key to include the element xpath, preventing chart destruction when
  the same report appears multiple times on a dashboard.
