LatteDB

LatteDB, an application (Python) of EspressoDB that is specialized to contain table definitions for lattice quantum chromodynamics (LQCD) calculations and analysis.

The main page of LatteDB is hosted on https://ithems.lbl.gov/lattedb.

Install

Clone the repo and install via pip

pip install [--user] [-e] .

You must set up the db-config.yaml and settings.yaml file. These files specify in which setup you want to use and how run the database connection.

For a general setup, take a look at the EspressoDB documentation.

If you want to connect to a specific database, contact the admin of this instance.

Docker

Run

docker-compose up

To build and run the local docker image (needs Docker installation).

You can interface with the image by running

docker-compose run app <bash command like lattedb --version>

Test the install

Run

pip install -r requirements-dev.txt
pytest

in the repo root to run the tests.

Usage

Host a local webpage

After configuration you can launch a local server with

lattedb runserver

and visit http://127.0.0.1:8000 (once the server is running.) Note that the address might change (look at the output of lattedb runserver).

Import in Python

Or connect your scripts with LatteDB

from lattedb.project.formfac.models import DiskConcatenatedFormFactor4DFile as DCFF4DF

files = DCFF4DF.objects.filter(exists=False)
print(files.count())
