Kadi problem: orbit_points event does not work #49

Open Gregg140 opened 10 years ago

Gregg140 commented 10 years ago

According to the Kadi documentation,

http://cxc.cfa.harvard.edu/mta/ASPECT/tool_doc/kadi/index.html

an available event is "orbit_points". When I try to use that, I get the following failure:

In [95]: orbpts = events.orbit_points.filter( start="2014:188", stop="2014:195").table
ERROR: AttributeError: 'module' object has no attribute 'orbit_points' [IPython.core.interactiveshell]

----> 1 orbpts = events.orbit_points.filter( start="2014:188", stop="2014:195").table

AttributeError: 'module' object has no attribute 'orbit_points'

Other events work fine. For example:

myorbits = events.orbits.filter( start="2014:188", stop="2014:195").table

succeeds:

In [93]: myorbits = events.orbits.filter( start="2014:188", stop="2014:195").table

In [94]: myorbits

Please let me know if my usage is incorrect.

Sorry, this is indeed a documentation error and the OrbitPoint and ManvrSeq models are not kadi events which can be queried using the usual mechanism. These are not "events" because they have no duration and instead correspond to points in time. (Yes the English is a bit ambiguous, but for kadi an "event" is something with a distinct start and stop time). You can still work with these models, but directly using the Django query mechanism. For example:

>>> from kadi.events import models
>>> models.<TAB>

As an action from this I will update the docs to reflect the correct list of query-able events and show this example for using OrbitPoints.
