Because the world needs an even simpler Django app for making a read-only API.

• Works over existing ORM models with little extra configuration needed.
• Can query the database directly via the ORM or via a Django Haystack SearchQuerySet to make full-text search queries via Solr or any Haystack backend.
• JSON, JSONP, CSV, and XML output formats.
• Automatic documentation generation.
• Nice handling of model fields with choices that use common.enum.
• Filtering is only allowed on indexed fields to prevent runaway queries.

• Python 2.x or 3.x.
• lxml.etree for the XML output format.

1. Put simplegetapi in your Python path and add simplegetapi to your INSTALED_APPS.

2. Configure which models will be exposed in the API and under what endpoint names. Add to settings.py:

   API_MODELS = { 'polls': 'myapp.Poll', }

3. Create a URLconf entry for API requests and the automatically-generated API documentation page.

   url(r'^api/v1', include('simplegetapi.urls')), url(r'^developers/api$', 'simplegetapi.views.api_documentation'),

This will expose the myapp.Poll class at /api/v1/polls.

3. Customize your models.

Optionally add any of the following to your models.

api_recurse_on: A list of model ForeignKey, OneToOneField, or ManyToManyField fields that should be walked recursively in API outputs. If a field of one of these types is not mentioned in this list, it will be included in API responses as just the primary key (ForienKey, OneToOneField) or list of primary keys (ManyToManyField) and not as an embedded object.

api_recurse_on_single: A list of fields as in api_recurse_on that additionally get recursively embedded in response outputs but only in API requests to a single object instance (not a query with filters).

api_additional_fields: A mapping from new fields to add to API responses to functions that generate those values.

api_filter_if: A mapping from field names to a tuple of what other fields must be specified in the query for filtering on the field to be allowed. Besides this, db_index=True fields and any prefix of a unique_together allow filtering.

api_example_id: The primary key of an example object to use in the automatic API documentation.

api_example_parameters: A dict giving some sample parameters to an API request to use as an example in the automatic API documentation.
