Gramex 1.55 release notes

FormHandler summarizes data

To get totals for any dataset, add ?by= to the URL. For example, this link summarizes the flags data

Instead of sum, you can use average, count, min, or max for each columns. For example, ?_by=&_c=c1|avg&_c=c2|count averages c1 and counts c2.

You can also apply aggregations for subsets of data. For example, ?_by=&continent=Europe shows the totals only for continent=Europe.

UI component upgrades

g1 is upgraded from 0.16.1 to 0.17.0, which introduces $().template() subtemplates, and fixes a minor bug in $.formhandler time zone handling.

Bootstrap-select has been updated to 0.13.10. This fixes bug #138.

Other UI components have also been updated to the latest patch versions.

Other enhancements

• Log viewer now supports scrolling when the number of categories is long. It also supports custom data transforms #160
• The Docker instance is based on Miniconda instead of the full Anaconda. This shrinks the image size (but it’s still at ~2.5GB). This fixes #81
• Documentation on custom fonts added #124

Bug fixes

• FormHandler date support for SQL filtering. Fixes #146 (#149)
• Preview for alert-capture works. Fixes Fixes #84
• Install SpaCy dependencies for CI #159
• Admin scheduler displays all schedules, including those that didn’t start on startup. The scheduler is also re-entrant – so we can run multiple times in parallel. (This may not be a )
