make init
copy all the data from AOL prod to your DB
If you have trouble installing psycopg2, you may need to add the path to
pg_config to your $PATH. You can find the proper path by using locate pg_config.
On my system, this does the trick:
export PATH=/usr/pgsql-9.3/bin:$PATH
Pillow is required, docs here. You
will probably need to install libjpeg-devel and libtiff-devel
Copy all the AOL pdf pages and photos to the media dir if you want some dummy data
rsync -v USERNAME@circe.rc.pdx.edu:/vol/www/aol/dev/media/pages/* media/pages
rsync -v USERNAME@circe.rc.pdx.edu:/vol/www/aol/dev/media/photos/* media/photos
It's very important to create an index like this:
CREATE INDEX observation_gist
ON observation
USING GIST (ST_BUFFER(ST_TRANSFORM(the_geom, 3644), 10));
This allows you to do intersection queries like:
ST_BUFFER(ST_TRANSFORM(the_geom, 3644), 10) && (SELECT the_geom FROM lake_geom WHERE reachcode = %s)
with very good performance. The magic '10' is arbitrary, but you should keep this consistent with DISTANCE_FROM_ITEM in lakes.models.
We cannot do this in a migration unfortunately, since the observation table is part of a different application/schema
Some custom migrations exist that add fields (like an hstore), and setup stored procs and triggers. So don't go blindly deleting them.
