MultiSlugRelatedField

class MultiSlugRelatedField(slug_fields[, many, required, queryset])

Serializer field which may be used to represent the target of a relationship using a set of fields on the target.

For example, the following serializer:

class AddressSerializer(serializers.ModelSerializer):
    postal_code = serializers.SlugRelatedField(many=True, read_only=True,
                                               slug_fields=('code', 'country'))

    class Meta:
        model = Address
        fields = ('street', 'city', 'state', 'postal_code')

Would serialize to a representation like this:

By default this field is read-write, although you can change this behavior using the read_only flag.

When using MultiSlugRelatedField as a read-write field, you will normally want to ensure that the slug fields corresponds to a set of model field declared as unique_together.

Arguments

• slug_fields - The fields on the target that should be used to represent it. This should be a set of fields that uniquely identifies any given instance. For example, postal_code', 'country'). required
• many - If applied to a to-many relationship, you should set this argument to True.
• required - If set to False the field will accept values of None or the empty-string for nullable relationships.
• queryset - By default ModelSerializer classes will use the default queryset for the relationship. Serializer classes must either set a queryset explicitly, or set read_only=True.
