Hello Guys,
I just wanted to let you know I pushed the json stuff to tip[1], which
has a minor backwards incompatibility with older quickstarts, if you
upgrade you will see this error.
MissingRendererError: The renderer for 'json' templates is missing.
Try adding the following line in you app_cfg.py:
"base_config.renderers.append('json')"
which despite it's obviousness, someone asked me what's up? so read
this and add that line.
I'll committed a patch so newer quickstart will have json on by
default.[2] Please note this introduces a "broken" tests, see below.
My last question regarding this ends up at how permissive should it
be. So far our json renderer will automagically render any object that
- has __json__ and it's a callable
- is of type date,datetime, Decimal, "Sqlalchemy class", SA result
proxy, row proxy or.
now we have a final choice here
a- make it call __repr__ and if that fails str(obj)
b- make it fail with an error that the item is not "jsonable"
c- make it a configurable option.
Currently the code implements "b" which is why the quickstart will
fail at /environ.json because it doesn't knows how to render a "logger
object", this is nice to catch errors But something you just want a
quick valid json string, in which case "a" seems better.
