A buddy for babies! Helps caregivers track sleep, feedings, diaper changes, and
|
|
tummy time to learn about and predict baby's needs without (*as much*) guess
|
|
work.

## Demo
|
|
|
|
A [demo of Baby Buddy](http://demo.baby-buddy.net) is available on Heroku.
|
|
The demo instance resets every hour. Login credentials are:
|
|
|
|
- Username: `admin`
|
|
- Password: `admin`
|
|
|
|
## Deployment
|
|
|
|
The default user name and password for Baby Buddy is `admin`/`admin`. For any
|
|
deployment, **log in and change the default admin password immediately**.
|
|
|
|
Many of Baby Buddy's configuration settings can be controlled using environment
|
|
variables - see [Configuration](#configuration) for detailed information.
|
|
|
|
### AWS Elastic Beanstalk
|
|
|
|
A basic [Elastic Beanstalk](https://aws.amazon.com/elasticbeanstalk/)
|
|
configuration is provided in `.ebextensions/babybuddy.config`. The steps
|
|
below are a rough guide to deployment. See [Working with Python](http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-apps.html)
|
|
for detailed information.
|
|
|
|
1. Clone/download the Baby Buddy repo
|
|
|
|
git clone https://github.com/cdubz/babybuddy.git
|
|
|
|
1. Enter the cloned/downloaded directory
|
|
|
|
cd babybuddy
|
|
|
|
1. Change the `SECRET_KEY` value to something random in `.ebextensions/babybuddy.config`
|
|
|
|
1. [Create an IAM user](http://docs.aws.amazon.com/IAM/latest/UserGuide/id_users_create.html) in AWS with EB, EC2, RDS and S3 privileges.
|
|
|
|
1. Initialize the Elastic Bean application (using the IAM user from the previous step)
|
|
|
|
eb init -p python-3.6
|
|
|
|
1. Create/deploy the environment! :rocket:
|
|
|
|
eb create -db -db.engine postgres
|
|
|
|
The create command will also do an initial deployment. Run `eb deploy` to
|
|
redeploy the app (e.g. if there are errors or settings are changed).
|
|
|
|
### Docker
|
|
|
|
A Docker deploy requires [Docker](http://docker.com/) and
|
|
[Docker Compose](https://docs.docker.com/compose/overview/) to create two
|
|
containers - one for the database and one for the application. Baby Buddy uses a
|
|
[multi-stage build](https://docs.docker.com/engine/userguide/eng-image/multistage-build/),
|
|
which requires Docker version 17.05 or newer.
|
|
|
|
1. Copy the `docker.env.example` to `docker.env` and set the `ALLOWED_HOSTS` and
|
|
`SECRET_KEY` variables within
|
|
|
|
cp docker.env.example docker.env
|
|
editor docker.env
|
|
|
|
*See [Configuration](#configuration) for other settings that can be
|
|
controlled by environment variables added to the `docker.env` file.*
|
|
|
|
1. Build/run the application
|
|
|
|
docker-compose up -d
|
|
|
|
1. Initialize the database *(first run/after updates)*
|
|
|
|
docker-compose exec app python manage.py migrate
|
|
|
|
1. Initialize static assets *(first run/after updates)*
|
|
|
|
docker-compose exec app python manage.py collectstatic
|
|
|
|
The app should now be locally available at
|
|
[http://127.0.0.1:8000](http://127.0.0.1:8000). See
|
|
[Get Started, Part 6: Deploy your app](https://docs.docker.com/get-started/part6/)
|
|
for detailed information about how to deployment methods with Docker.
|
|
|
|
### Nanobox
|
|
|
|
An example [Nanobox](https://nanobox.io/) configuration, `boxfile.yml`, is
|
|
provided with Baby Buddy. The steps below are a rough guide to deployment. See
|
|
[Create and Deploy a Custom Django App](https://guides.nanobox.io/python/django/)
|
|
for detailed information about Nanobox's deployment and configuration process.
|
|
|
|
1. Clone/download the Baby Buddy repo
|
|
|
|
git clone https://github.com/cdubz/babybuddy.git
|
|
|
|
1. Enter the cloned/downloaded directory
|
|
|
|
cd babybuddy
|
|
|
|
1. Add the `SECRET_KEY` and `DJANGO_SETTINGS_MODULE` environment variables
|
|
|
|
nanobox evar add DJANGO_SETTINGS_MODULE=babybuddy.settings.nanobox
|
|
nanobox evar add SECRET_KEY=<CHANGE TO SOMETHING RANDOM>
|
|
|
|
*See [Configuration](#configuration) for other settings that can be
|
|
controlled by environment variables.*
|
|
|
|
1. Deploy! :rocket:
|
|
|
|
nanobox deploy
|
|
|
|
### Heroku
|
|
|
|
[](https://heroku.com/deploy)
|
|
|
|
For manual deployments to Heroku without using the deploy button, make sure to
|
|
create two settings before pushing using `heroku config:set`:
|
|
|
|
heroku config:set DJANGO_SETTINGS_MODULE=babybuddy.settings.heroku
|
|
heroku config:set SECRET_KEY=<CHANGE TO SOMETHING RANDOM>
|
|
|
|
See [Configuration](#configuration) for other settings that can be controlled
|
|
by `heroku config:set`.
|
|
|
|
### Manual
|
|
|
|
There are a number of ways to deploy Baby Buddy manually to any server/VPS.
|
|
The application can run fine in low memory (below 1GB) situations, however a
|
|
32-bit operating system is recommended in such cases. This is primarily
|
|
because the build process can be memory intensive and cause excessive memory
|
|
usage on 64-bit systems. If all fails, assets can be built on a local machine
|
|
and then uploaded to a server.
|
|
|
|
#### Requirements
|
|
|
|
- Python 3.4+, pip, pipenv
|
|
- Web server ([nginx](http://nginx.org/), [Apache](http://httpd.apache.org/), etc.)
|
|
- Application server ([uwsgi](http://projects.unbit.it/uwsgi), [gunicorn](http://gunicorn.org/), etc.)
|
|
- Database ([sqlite](https://sqlite.org/), [Postgres](https://www.postgresql.org/), [MySQL](https://www.mysql.com/), etc.)
|
|
- NodeJS 8.x and NPM 5.x (for building assets)
|
|
- Gulp (for building assets)
|
|
|
|
#### Example deployment
|
|
|
|
*This example assumes a 512MB VPS instance with Ubuntu 16.04 **x32**.* It uses
|
|
Python 3.x, nginx, uwsgi and sqlite and should be sufficient for a few users
|
|
(e.g. two parents and 1+ child).
|
|
|
|
1. Install Python 3.x, pip, nginx and uwsgi

|
|
env = DJANGO_SETTINGS_MODULE=%(project).settings.production
|
|
master = True
|
|
vacuum = True
|
|
|
|
See the [uWSGI documentation](http://uwsgi-docs.readthedocs.io/en/latest/)
|
|
for more advanced configuration details.
|
|
|
|

|
|
``pipenv --venv``.*
|
|
|
|
1. Create and configure the nginx server
|
|
|
|
sudo vim /etc/nginx/sites-available/babybuddy
|
|
sudo ln -s /etc/nginx/sites-available/babybuddy /etc/nginx/sites-enabled/babybuddy
|
|
sudo service nginx restart
|
|

|
|
}
|
|
}
|
|
|
|
See the [nginx documentation](https://nginx.org/en/docs/) for more advanced
|
|
configuration details.
|
|
|
|
1. That's it (hopefully)! :tada:
|
|
|
|
## Configuration
|
|
|
|
Environment variables can be used to define a number of configuration settings.
|
|
Baby Buddy will check the application directory structure for an `.env` file or
|
|
take these variables from the system environment. **System environment variables
|
|
take precedence over the contents of an `.env` file.**
|
|
|
|
- [`ALLOWED_HOSTS`](#allowed_hosts)
|
|
- [`ALLOW_UPLOADS`](#allow_uploads)
|
|
- [`DEBUG`](#debug)
|
|
- [`NAP_START_MAX`](#nap_start_max)
|
|
- [`NAP_START_MIN`](#nap_start_min)
|
|
- [`SECRET_KEY`](#secret_key)
|
|
- [`TIME_ZONE`](#time_zone)
|
|
|
|
### `ALLOWED_HOSTS`
|
|
|
|
*Default: * (any)*
|
|
|
|
This option may be set to a single host or comma-separated list of hosts
|
|
(without spaces). This should *always* be set to a specific host or hosts in
|
|
production deployments.
|
|
|
|
See also: [Django's documentation on the ALLOWED_HOSTS setting](https://docs.djangoproject.com/en/1.11/ref/settings/#allowed-hosts)
|
|
|
|
### `ALLOW_UPLOADS`
|
|
|
|
*Default: True*
|
|
|
|
Whether or not to allow uploads (e.g. of Child photos). For some deployments
|
|
(AWS, Heroku, Nanobox) this setting will default to False due to the lack of
|
|
available persistent storage.
|
|
|
|
### `DEBUG`
|
|
|
|
*Default: False*
|
|
|
|
When in debug mode, Baby Buddy will print much more detailed error information
|
|
for exceptions. This setting should be *False* in production deployments.
|
|
|
|
See also [Django's documentation on the DEBUG setting](https://docs.djangoproject.com/en/1.11/ref/settings/#debug).
|
|
|
|
### `NAP_START_MAX`
|
|
|
|
*Default: 18:00*
|
|
|
|
The maximum *start* time (in the instance's time zone) before which a sleep
|
|
entry is consider a nap. Expects the format %H:%M.
|
|
|
|
### `NAP_START_MIN`
|
|
|
|
*Default: 06:00*
|
|
|
|
The minimum *start* time (in the instance's time zone) after which a sleep
|
|
entry is considered a nap. Expects the format %H:%M.
|
|
|
|
### `SECRET_KEY`
|
|
|
|
*Default: None*
|
|
|
|
A random, unique string must be set as the "secret key" before Baby Buddy can
|
|
be deployed and run.
|
|
|
|
See also [Django's documentation on the SECRET_KEY setting](https://docs.djangoproject.com/en/1.11/ref/settings/#secret-key).
|
|
|
|
### `TIME_ZONE`
|
|
|
|
*Default: Etc/UTC*
|
|
|
|
The time zone to use for the instance. See [List of tz database time zones](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones)
|
|
for all possible values.
|
|
|
|
## API
|
|
|
|
Baby Buddy uses the [Django REST Framework](http://www.django-rest-framework.org/)
|
|
(DRF) to provide a REST API.
|
|
|
|
### Authentication
|
|
|
|
By default, the [TokenAuthentication](http://www.django-rest-framework.org/api-guide/authentication/#tokenauthentication)
|
|
and [SessionAuthentication](http://www.django-rest-framework.org/api-guide/authentication/#sessionauthentication)
|
|
classes are enabled. Session authentication covers local API requests made by
|
|
the application itself. Token authentication allows external requests to be
|
|
made.
|
|
|
|
:exclamation: **In a production environment, token authentication should only
|
|
be used for API calls to an `https` endpoint.** :exclamation:
|
|
|
|
Each user is automatically assigned an API key that can be used for token
|
|
authentication. This key can be found on the User Settings page for the logged
|
|
in the user. To use a key for an API request, set the request `Authorization`
|
|
header to `Token <user-key>`. E.g.
|
|
|
|
Authorization: Token 2h23807gd72h7hop382p98hd823dw3g665g56
|
|
|
|
If the `Authorization` header is not set or the key is not valid, the API will
|
|
return `403 Forbidden` with additional details in the response body.
|
|
|
|
### Responses
|
|
|
|
#### `GET`
|
|
|
|
Returns JSON data in the response body in the following format:
|
|
|
|
{
|
|
"count":<int>,
|
|
"next":<url>,
|
|
"previous":<url>,
|
|
"results":[{...}]
|
|
}
|
|
|
|
- `count`: Total number of records (*in the database*, not just the response).
|
|
- `next`: URL for the next set of results.
|
|
- `previous`: URL for the previous set of results.
|
|
- `results`: An array of the results of the request.
|
|
|
|
#### `OPTIONS`
|
|
|
|
Returns JSON data in the response body describing the endpoint and available
|
|
options for `POST` requests. The following example describes the
|
|
`/api/children` endpoint:
|
|
|
|
{
|
|
"name": "Child List",
|
|
"description": "",
|
|
"renders": [
|
|
"application/json",
|
|
"text/html"
|
|
],
|
|
"parses": [
|
|
"application/json",
|
|
"application/x-www-form-urlencoded",
|
|
"multipart/form-data"
|
|
],
|
|
"actions": {
|
|
"POST": {
|
|
"id": {
|
|
"type": "integer",
|
|
"required": false,
|
|
"read_only": true,
|
|
"label": "ID"
|
|
},
|
|
[...]
|
|
}
|
|
}
|
|
}
|
|
|
|
#### `POST`
|
|
|
|
Returns JSON data in the response body describing the added/updated instance or
|
|
error details if errors exist. Errors are keyed by either the field in error or
|
|
the general string "non_field_errors" (usually when validation incorporates
|
|
multiple fields).
|
|
|
|
## Development
|
|
|
|

|
|
- Gulp
|
|
|
|
### Installation
|
|
|
|
1. Install pipenv
|
|
|
|
pip install pipenv
|
|
|
|
1. Install required Python packages, including dev packages
|
|
|
|
pipenv install --dev
|
|
|
|
1. Install Gulp CLI
|
|
|
|
npm install -g gulp-cli
|
|
|
|
1. Install required Node packages
|
|
|
|
npm install
|
|
|
|
1. Set, at least, the `DJANGO_SETTINGS_MODULE` environment variable
|
|
|
|
export DJANGO_SETTINGS_MODULE=babybuddy.settings.development
|
|
|
|
This process will differ based on the host OS. The above example is for
|
|
Linux-based systems. See [Configuration](#configuration) for other settings
|
|
and methods for defining them.
|
|
|
|
1. Migrate the database
|
|

|
gulp migrate
|
|
|
|
1. Build assets and run the server
|
|
|
|
gulp
|
|
|
|
This command will also watch for file system changes to rebuild assets and
|
|
restart the server as needed.
|
|
|
|
Open [http://127.0.0.1:8000](http://127.0.0.1:8000) and log in with the default
|
|
user name and password (`admin`/`admin`).
|
|
|
|
### Gulp commands
|
|
|
|
Baby Buddy's Gulp commands are defined and configured by files in the
|
|
[`gulpfile.js`](gulpfile.js) folder. Django's management commands are defined
|
|
in the [`babybuddy/management/commands`](babybuddy/management/commands) folder.
|
|
|
|
- [`gulp`](#gulp)
|
|
- [`gulp build`](#build)
|
|
- [`gulp collectstatic`](#collectstatic)
|
|
- [`gulp compress`](#compress)
|
|
- [`gulp coverage`](#coverage)
|
|
- [`gulp extras`](#extras)
|
|
- [`gulp fake`](#fake)
|
|
- [`gulp lint`](#lint)
|
|
- [`gulp makemigrations`](#makemigrations)
|
|
- [`gulp migrate`](#migrate)
|
|
- [`gulp reset`](#reset)
|
|
- [`gulp runserver`](#runserver)
|
|
- [`gulp scripts`](#scripts)
|
|
- [`gulp styles`](#styles)
|
|
- [`gulp test`](#test)
|
|
|
|
#### `gulp`
|
|
|
|
Executes the `build` and `watch` commands and runs Django's development server.
|
|
|
|
#### `build`
|
|
|
|
Creates all script, style and "extra" assets and places them in the
|
|
`babybuddy/static` folder.
|
|
|
|
#### `collectstatic`
|
|
|
|
Executes Django's `collectstatic` management task. This task relies on files in
|
|
the `babybuddy/static` folder, so generally `gulp build` should be run before
|
|
this command for production deployments. Gulp also passes along
|
|
non-overlapping arguments for this command, e.g. `--no-input`.
|
|
|
|
#### `compress`
|
|
|
|
:exclamation: *DEPRECATED* :exclamation:
|
|
|
|
Compresses built scripts and styles. This command has been deprecated in favor
|
|
of WhiteNoise's compression as part of the `collectstatic` command.
|
|
|
|
#### `coverage`
|
|
|
|
Create a test coverage report. See [`.coveragerc`](.coveragerc) for default
|
|
settings information.
|
|
|
|
#### `extras`
|
|
|
|
Copies "extra" files (fonts, images and server root contents) to the build
|
|
folder.
|
|
|
|
#### `fake`
|
|
|
|
Adds some fake data to the database. By default, ``fake`` creates one child and
|
|
31 days of random data. Use the `--children` and `--days` flags to change the
|
|
default values, e.g. `gulp fake --children 5 --days 7` to generate five fake
|
|
children and seven days of data for each.
|
|
|
|
#### `lint`
|
|
|
|
Executes Python and SASS linting for all relevant source files.
|
|
|
|
#### `makemigrations`
|
|
