# Django Spring

### Installing
```bash
pip install django-spring --upgrade
```

### Usage

```bash
# First start the server:
spring start

# Then run a manage.py command (eg. test)
spring test --keepdb

# Optionally, specify a settings module:
DJANGO_SETTINGS_MODULE="base.settings" spring test --keepdb
```

### Comparison
For a large project I tested against, it reduced the test time from 27.8s to 14.5s! Most of the time savings are from app startup, so the largest difference will be felt for running small test suites for large projects.

#### manage.py
```
# time ./manage.py test --keepdb billing_service/tests/test_user.py
..........

sys     0m2.510s
```

#### spring
```
# time spring test --keepdb billing_service/tests/test_user.py
[APP] running command `test --keepdb billing_service/tests/test_user.py`

Ran 10 tests in 4.714s

real    0m14.457s
user    0m0.180s
sys     0m0.100s
```

### Tweakable env vars

`DJANGO_SETTINGS_MODULE`: The path to your settings module  (eg. `base.settings`)

`CODE_RELOADER_POLL_PERIOD`: The number of seconds to wait between polling.
Setting this higher will improve performance when using the stat reloader.

`LOG_LEVEL`: (DEBUG, INFO, WARN, ERROR, CRITICAL)
