SCC access script
=================

This small scripts permits interacting with the Single Calculus Chain through
the command line. Specifically, with the script you can:

* Upload a file to the SCC for processing
* Download the processed files and graphs
* Delete an existing measurement from the SCC (with appropriate privileges)

The main functions are implemented in a class (SCC) that you can also import 
and use in your custom scripts.

The script does not provide any feedback if a file upload fails. Before using
the script, you will need to upload some files manually and be confident that 
your SCC file format and processing settings are correct.

Please note that this is not part of the "official" SCC tools. I will update
it when I have time but I cannot guarantee to maintain it in the long run.

Any suggestions for improvements and new features are more than welcome.


Installation
------------

The only requirement for running this program is the requests python module.
If you have pip installed you can install it by::

   pip install requests.

See http://docs.python-requests.org/en/latest/user/install/ for more details.

You can use the script by cloning this mercurial repository. Alternatively, you 
can just coppy the scc_access.py and and settings.sample.py files to a local 
directory.


Settings
--------
You will need to change some user-defined settings in a settings.py file. You
can rename the settings.sample.py file to settings.py and follow the instructions 
there.

Specifically, you will need to:

1. Change the BASIC_LOGIN and DJANGO_LOGIN to your credentials.
2. Change the OUTPUT_DIR to the location were the results will be stored.

Please not that it's not a good idea to store your own credentials in the settings
file. The standard user has "Station Management" privileges and if the credentials 
are stolen, someone could change/delete the stations settings from the SCC database.
For this, it is better to use a used account with minimum access settings, that
can only upload files and measurements.


Usage
-----

You can upload a file specifying the username and the system id::

   python scc_access.py 20110101po01.nc 125

If you want to wait for the processing to finish and download the resulting files
you need to define the -p flag::

   python scc_access.py 20110101po01.nc 125 -p

If you want to delete an existing measurement id from the database use the -d flag and
the measurement id::
   
   python scc_access.py -d 20110101po01

For more information on the syntax type::
   
   python scc_access.py -h
