NosFinancesLocales.fr

This is the code in production for the website NosFinancesLocales.fr.

The main goal of this project is to illustrate french cities financial data recently freed by Regards Citoyens.

It is also an opportunity to show server and client code and how to install such a stack. Special thanks to these awesome projects:

## CONFIG

* Create postgresql db and add necessary extensions
```bash

 CREATE EXTENSION hstore;
 CREATE EXTENSION postgis;
 CREATE EXTENSION unaccent; # for city search
 CREATE EXTENSION pg_trgm; # indexation for city search
 ```

TODO: add localfinance pyramid app in virtualenv


## PREPARE DB, FILL IT

python -m localfinance.scripts.initializedb production.ini
python -m localfinance.scripts.filladminzone production.ini data/COMMUNES_4326/COMMUNE.shp
python -m localfinance.scripts.filladminzonefinance production.ini data/city_all.csv


## POSTGRESQL OPTIMIZATION

Add indexes on:
* CREATE INDEX adminzone_name_lower_unaccent_idx ON adminzone USING gist (lower(unaccent(name)) gist_trgm_ops);
* CREATE INDEX adminzonefinance_adminzone_id_index ON adminzonefinance
(adminzone_id)



## PRECOMPUTE STATS AND TILES

TODO: add bash script and improve code


## RUN

TODO: add make file
