#St Andrews Observatory Project Backend

This backend has two functions. It can a) scrape weather from sources into an archive and b) parse fits files for display on the frontend.

The main deployment steps are based on resolving dependancies.

clone repo

git clone https://github.com/billytrend/st-andrews-observatory-backend.git

install f2n

svn export https://svn.epfl.ch/svn/mtewes-public/trunk/f2n ./f2n
cd f2n/
python setup.py install
cd ../
rm -r f2n/

install pip dependancies

pip install xmltodict
pip install feedparser
apt-get install python-lxml
pip install lxml
pip install astropy
pip install scipy
pip install pyfits
pip install numpy

install pillow

make sure this includes the version 2.4.0 more recent versions have a critical bug in them

pip install pillow==2.4.0  

add a data folder (should be at the web app root)

mkdir ??/data

First initialise the data folder in the web app root.

python src/main.py -i ??/path_to_fits_file_repo ??/data

This will set all the current fits files to ignore so only new fits files will be parsed - may make it appear as though the site isn't working until the first fits files come through.

Parses latest weather forecasts to the data folder

python src/main.py -w ??/data

Parses latest fits files to data folder. Does nothing if there are no new files.

python src/main.py -f ??/path_to_fits_file_repo ??/data

* Check missing dependancies
* Check pillow is on the right version
* Check that the apis are still at the right version
* Let me (wt6@st-andrews.ac.uk) know if there are problems. I'll be happy to help.
