django-rf-candv-choices 1.0.0

Serializing choices

For example, you have some model which uses candv_x.django.choices.ChoiceField to store one of allowed values. This might be a User model, which has user_role field, where values for user_role are defined by USER_ROLES constants container.

Use candv_x.rest_framework.choices.ChoiceField for user_role serialization:

from rest_framework import serializers
from candv_x.rest_framework.choices import ChoiceField

from .constants import USER_ROLES
from .models import User


class UserSerializer(serializers.ModelSerializer):
    user_role = ChoiceField(USER_ROLES)

    class Meta:
        model = User
        fields = ('id', 'name', 'user_role', )

Exposing choices to the outer world

If you need to expose list of possible choices for your field, then you can use a ChoicesList base view to get a class-based view:

from candv_x.rest_framework.choices import ChoicesList

from .constants import USER_ROLES


class UserRoleList(ChoicesList):
    choices = USER_ROLES

The only thing you need to do is to define choices attribute.

There is a faster way also: you can use a coalitions_list view factory to get a function-based view:

from candv_x.rest_framework.choices import simple_choices_list

from .constants import USER_ROLES


user_role_list = simple_choices_list(USER_ROLES)
