bridgeql 0.2.2

BridgeQL
bridgeql is part of VMware's support for open source development
and community.
A library which will add feature to serve your model over rest API

This will allow users to make ORM query based on any models present in the django app
This will ask user to provide request in defined format and will serve the API response as json data
This will allow users to make filter, selection, ordering, slicing and count of model objects

As of today we only support for django, will add support for sqlalchemy soon.

Django Integration
Installation
You can install it directly from pypi.org using
pip install bridgeql

The bridgeql library can be integrated to the Django app by editing settings
file by including bridgeql in the settings.INSTALLED_APPS variable.
Another change required is to add a url to your existing project as
projectname/projectname/settings.py

INSTALLED_APPS = [
...
'bridgeql',
...
]

URLs Configuration
In your project you can edit urls.py, to include the bridgeql urls.
from bridgeql.django import urls as bridgeql_urls
...

urlpatterns = [
...
path('api/bridgeql/', include(bridgeql_urls)),
...
]
...

This way your app will be ready to serve the REST API to expose model query, you can request the API
to perform basic CRUD operations using one of the following URLs

Create: create/db_name/app_name/model_name
Read: read/db_name/app_name/model_name/<?pk>
Update: update/db_name/app_name/model_name/pk
Delete: delete/db_name/app_name/model_name/pk

Example Usage:
import requests

params = {
'filter': {
'os__name': 'os-name-1'
},
'fields': ['ip', 'name', 'id'],
'exclude': {
'name': 'machine-name-11'
},
'order_by': ['ip'],
'limit': 5,
'offset': 10, # default 0
}
# db_name could be default
api_url = '<yoursite.com>/api/bridgeql/read/default/machine/Machine'
resp = requests.get(api_url, {'payload': json.dumps(params)})
result = resp.json()

The above parameters will translate into running the model query for Machine model of machine django app.
Machine.objects.using('default')
.filter(os__name = 'os-name-1')
.exclude(name = 'machine-name-11')
.values(['ip', 'name', 'id'])
.order_by('ip')[10:15] # offset: offset + limit


BridgeQL Settings
Settings available in BridgeQL and their default values
BRIDGEQL_ALLOWED_APPS
Default: [list of local apps] (list)
By default, it will try to lookup your local apps for the project, considering settings.BASE_DIR or settings.SITE_ROOT (whichever is found) as your project root directory. If none of this will be available, WARNING will be there to setup BRIDGEQL_ALLOWED_APPS as application starts up.
Adding values as list of desired apps to BRIDGEQL_ALLOWED_APPS will allow you expose models only for the selected apps.
This way you can add django backend apps as well as third party apps e.g. django.contrib.auth which can expose User model.
You can combine next settings BRIDGEQL_RESTRICTED_MODELS to restrict few columns of that particular model e.g password.
BRIDGEQL_ALLOWED_APPS = ['machine', 'django.contrib.auth']


BRIDGEQL_RESTRICTED_MODELS
Default: {} (Empty dictionary)
Dictionary mapping app_label.model_name strings to list/bool(True). The value represents list of fields to be restricted for the model as provided in key. If the value is set to True, all the fields of that model will be restricted to lookup.
BRIDGEQL_RESTRICTED_MODELS = {
'auth.User': True,
'machine.OperatingSystem': ['license_key'],
}


BRIDGEQL_AUTHENTICATION_DECORATOR
Default:
{
'reader': '',
'writer': ''
}

Above setting allows you to use an authentication decorator to authenticate your client's requests.
You can provide a custom authentication decorator,
for reader and writer separately, whichever suits your application usecase, e.g login_required, same_subnet, etc.
Default value for BRIDGEQL_AUTHENTICATION_DECORATOR will allow you to access API without authentication.
BRIDGEQL_AUTHENTICATION_DECORATOR = {
'reader': 'bridgeql.auth.basic_auth',
'writer': 'bridgeql.auth.basic_auth'
}

bridgeql.auth.basic_auth is available as a basic authentication method where you can pass authorization header as
Authorization: Basic base64(username:password) for each request.
