Can't view individual runs in browser with pecan 0.8+

[mattboehm]

When you click an individual run ID with pecan 0.8+, you get a 404 error. This does work with pecan 0.6, so somewhere between those two versions, it stopped working.

The most promising hint seems to be "Fixed a routing bug for generic subcontrollers.": https://pecan.readthedocs.org/en/latest/changes.html?highlight=redirect#id10

Short-term solution: force a specific pecan version in requirements.txt

Long-term solution: figure out how pecan routes work now, and fix the problem.

If you set up debug mode, do you get a traceback for the 404? I can't remember if pecan reports tracebacks in that case.

[mattboehm]

Unfortunately, I don't see tracebacks when 404s occur because the exception is caught when Pecan routes you to a debug page. The exception is typically thrown when Pecan has exhausted all controllers/methods without finding a match. I think the best approach will be to poke at these routes in a python shell or read the documentation until the problem makes sense.

(I tried various ways of using smiley to inspect the pecan server, but ran into bugs along the way)
