bridgeql 0.1.7b0

Query language to bridge the gap between REST API and ORM capability

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

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'
    ...
    ]

On 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 an API like follows:

    params = {
       'using': 'db1',
       'app_name': 'machine', # required
       'model_name': 'Machine', # required
       'filter': {
           'os__name': 'os-name-1'
        },
        'fields': ['ip', 'name', 'id'],
        'exclude': {
           'name': 'machine-name-11'
        },
        'order_by': ['ip'],
        'limit': 5,
        'offset': 10, # default 0
    }
    api_url = '<yoursite.com>/api/bridgeql/dj_read'
    resp = make_post_api_call(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('db1')
                .filter(os__name = 'os-name-1')
                .exclude(name = 'machine-name-11')
                .values(['ip', 'name', 'id'])
                .order_by('ip')[10:15] # offset: offset + limit
