model mixins

The following mixins are available for your model classes:

Timestampable

Provides created_at and updated_at fields.

Ownerable

Provides a owner field which references settings.AUTH_USER_MODEL

view mixins

The following mixins are available for your view classes:

SelectRelatable

Provides a class variable select_related that allows you to provide a tuple or list of related models to perform a select_related on.

django-rest-framework filter backend

A custom filter backend that provides a generic filter query string parameter.

Convert a search query into a dictionary.

A search query like this one:

party: stakker is akker category:"hiha hoi"

Will be converted to a python dict:

{
    'category': 'hiha hoi',
    'party': None,
    'search': 'stakker is akker'
}

It uses a regular expression to split every token on the : separator instead of using the string.split() function. This is important to distinguish between the following use cases:

- 'party:'        => {'party': None}
- 'party:tester'  => {'party': 'tester'}
- 'party: tester' => {'search': 'party: tester'}

django-rest-framework serializer mixins

The following mixins are available for your serializer classes:

Projectable

Gives your api consumers the ability to control what fields are included in the api response using a configurable query string parameter (defaults to _fields).

E.g. a GET /resources?_fields=name,description,count will only return the specified 3 fields of the resource.

Ownerable

Limit the related field options to only those records owned by the current logged in user.
