I have a view that spits out a simple polygon display after the polygon has been transformed to srid 900913. It has worked fine for a good period of time, but now is failing for only a select minority of the records in my geospatial model. The traceback looks something like this. Any idea what could be causing it? I suspect it isn't the GDAL_DATA directory error describe in the docs, since the view is working perfectly find for the majority of my records -- and had been working for these problematic records as little as a few hours ago.

I hate to ask the obvious question, but what might have changed on your
end in the past few hours? Server restart so it's now reading new code?
(if so, how old would the previous running code have been?) System
library upgrades (e.g. a "yum update" or apt update)? Computer programs
don't just get dusty and stop working, so something changed. Big
challenge is working out what that might be. Think hard about what might
be different now, as compared to the system as it stood at lunchtime
today.

Hey Ben,
The first thing I would do is wrap that problem point like:
try:
object.polygon.transform(900913)
except Exception, E:
raise Exception('%s: geometry was: %s' % (E, objects.polygon.wkt))
Then send us along that error. Transforms into 900913 will bail for
malformed data or data that is outside the extent the projection can
handle (gt or lt 90 degrees for example).

Malcolm -- I'm totally tuned in to what you're saying, and I suspect it still might be the outcome. However, I've made no changes to the code today and already tried an apache restart. Though maybe I should clear out the cache and try a more thorough flush?
Dane -- thanks for the pointer. I've run what suggested and received the following, though I'm not sure what to make of it.

You could try to load the original polygon with fromstr() and see what
happens. Maybe the orginal polygon is corrupted somehow.
>>> from django.contrib.gis.geos import fromstr
>>> multipolygon = fromstr('the wkt from the polygon in question', srid=your_srid)
Looks like your wkt is cut off at the bottom.

Right,
Matt's thinking the same thing as I am.
But, I forgot that the geometry gets transformed in place, and ideally
we'd like to see the geometry pre-transform:
So try this:
try:
clone = object.polygon.clone()
object.polygon.transform(900913)
except Exception, E:
raise Exception('%s: geometry was: "%s", and is now: "%s" ' %
(E, clone.wkt,objects.polygon.wkt))
As an aside, it would be nice to know what postgis thinks about the
validity of the data:
What does this give:
Site.objects.extra(where=['NOT ST_IsValid(polygon)'])

Ah, nice.
So your geometries are valid... but if my code worked correctly (truly cloned the original geometry) it appears that your source data is already in 900913. If that is the case you surely cannot transform 900913 into 900913.
What is your geometry field 'srid' ?

The models.py snippet is:
polygon = models.MultiPolygonField(srid=4269)
Hmm. While this was all going on, I continued to backtrack and found that the polygon map widget in my admin was appearing blank in the four bad records -- unusual considering it had been filled earlier in the day. And also a little weird since that, we now see wrongly projected, data was appearing in the shell.
So what I did was take Matt's advice and reload just those bad records with fresh wkt from the development database, and found that the problem disappeared.
So, I guess, somehow the polygons got screwed today. And I'm really not sure how. I only have one trusted user in there, unless they're handing it out, and I'm not sure how they'd accomplish such a screw up through the admin. Hmm. I'll have to interrogate them a little tomorrow. But otherwise, I'm stumped, but at least temporarily happy the problem is fixed.
Thank you so much for the quick response, listers. The GeoDjango community continues to be a daily inspiration to me. And a reason to be excited to work in my weird profession at a time when there are a lot other reasons to be down.

How did you install PROJ.4? See the footnote in the installation docs:
http://geodjango.org/docs/install.html#proj4
If you don't have the datum-shifting files installed (at `configure`
time) it can mess up geometries edited in the admin as you describe.

This a problem I set aside for the moment because I didn't require the
fix, but I'm hoping to address it again now.
Again, the errors only arose after I installed GeoDjango on a new
machine, which now serves as a dedicated database server.
Because of that background, I suspect the culprit is probably -- as
Justin suggests -- in that installation process somewhere. However, as
I pasted above, I think I did compile PROJ.4. along with GEOS.
I just ran my geos tests again and seemed to pass, though I'm not sure
if it's even verified here. I've pasted that below. Could it be a
problem with GDAL or something else in the installation process?
If anyone has any ideas, I'd greatly appreciate to hear them. And if
there's any more information I could provide, feel free to prod me.
Thanks,
Ben.

fix, but I'm hoping to address it again now.
Again, the errors only arose after I installed GeoDjango on a new
machine, which now serves as a dedicated database server.
Because of that background, I suspect the culprit is probably -- as
Justin suggests -- in that installation process somewhere. However, as
I pasted above, I think I did compile PROJ.4. along with GEOS.
I just ran my geos tests again and seemed to pass, though I'm not sure
if it's even verified here. I've pasted that below. Could it be a
problem with GDAL or something else in the installation process?
If anyone has any ideas, I'd greatly appreciate to hear them. And if
there's any more information I could provide, feel free to prod me.
Thanks,
Ben.

You know what. I think I might have figured it out and, who would have guessed, I think the idiot user might have been the problem.
I found a dangling admin.pyc file hanging around on the server that is the ghost of a similar, identically name, set of instructions to ones I wrote for a new app.
I had long-since removed the admin.py file that came with it, but perhaps the pyc was still firing and registrations on the new admin crossed the wires with the old pyc file.
I'm not sure that's it, but removing that pyc file and restarting apache seems to have aced the problem.
If that was indeed it, sorry to have wasted everyone's time.
Ben.
