The guide to the parser-model-view architecture is in the architecture document.
This page will describe the usual things that go wrong: the parsers that break when faced with user-generated data and how to fix them. Common error messages. How to set up troggle on a new machine. Copies of the older material where that is illuminating.
It concentrates on showing how to find and fix import errors so that the troggle-generated webpages are complete and not full of gaps.
Intended audience: Ideally someone who is not a python programmer will be able to use this page to help them fix import errors.
Also here we will explain the useful diagnostic pages such as
experimental
pathsreport
survey_scans
/admin/core/dataissue/
tunneldata
statistics
