pulpcore.plugin.serializers¶
All serializers documented here should be imported directly from the pulpcore.plugin.serializers
namespace.
- class pulpcore.plugin.serializers.ArtifactSerializer(*args, **kwargs)¶
- validate(data)¶
Validate file by size and by all checksums provided.
- Parameters
data (
django.http.QueryDict
) – QueryDict mapping Artifact model fields to their values- Raises
rest_framework.exceptions.ValidationError – When the expected file size or any of the checksums don’t match their actual values.
- class pulpcore.plugin.serializers.AsyncOperationResponseSerializer(*args, **kwargs)¶
Serializer for asynchronous operations.
When a field is instantiated, we store the arguments that were used, so that we can present a helpful representation of the object.
- class pulpcore.plugin.serializers.ContentChecksumSerializer(*args, **kwargs)¶
Provide a serializer with artifact checksum fields for single artifact content.
If you use this serializer, it’s recommended that you prefetch artifacts:
Content.objects.prefetch_related(“_artifacts”).all()
When a field is instantiated, we store the arguments that were used, so that we can present a helpful representation of the object.
- class pulpcore.plugin.serializers.ContentGuardSerializer(*args, **kwargs)¶
- class pulpcore.plugin.serializers.DetailRelatedField(*args, **kwargs)¶
RelatedField for use when relating to Master/Detail models
When using this field on a Serializer, relate it to the Master model in a Master/Detail relationship, and it will automatically cast objects to their Detail type before generating URLs for them.
Subclasses must indicate the Master model they represent by declaring a queryset in their class body, usually <MasterModelImplementation>.objects.all().
- get_object(*args, **kwargs)¶
Return the object corresponding to a matched URL.
Takes the matched URL conf arguments, and should return an object instance, or raise an ObjectDoesNotExist exception.
- use_pk_only_optimization()¶
If the lookup field is pk, DRF substitutes a PKOnlyObject as an optimization. This optimization breaks with Detail fields like this one which need access to their Meta class to get the relevant view_name.
- class pulpcore.plugin.serializers.DistributionSerializer(*args, **kwargs)¶
The Serializer for the Distribution model.
The serializer deliberately omits the the publication and repository_version field due to plugins typically requiring one or the other but not both.
To include the
publication
field, it is recommended plugins define the field:publication = DetailRelatedField( required=False, help_text=_("Publication to be served"), view_name_pattern=r"publications(-.*/.*)?-detail", queryset=models.Publication.objects.exclude(complete=False), allow_null=True, )
To include the
repository_version
field, it is recommended plugins define the field:repository_version = RepositoryVersionRelatedField( required=False, help_text=_("RepositoryVersion to be served"), allow_null=True )
Additionally, the serializer omits the
remote
field, which is used for pull-through caching feature and only by plugins which use publications. Plugins implementing a pull-through caching should define the field in their derived serializer class like this:remote = DetailRelatedField( required=False, help_text=_('Remote that can be used to fetch content when using pull-through caching.'), queryset=models.Remote.objects.all(), allow_null=True )
- class pulpcore.plugin.serializers.ExportSerializer(*args, **kwargs)¶
Base serializer for Exports.
- class pulpcore.plugin.serializers.ExporterSerializer(*args, **kwargs)¶
Base serializer for Exporters.
- static validate_path(value, check_is_dir=False)¶
Check if path is in ALLOWED_EXPORT_PATHS.
- Parameters
value – The user-provided value path to be validated.
check_is_dir – If true, insure path ends with a directory
- Raises
ValidationError – When path is not in the ALLOWED_EXPORT_PATHS setting.
- Returns
The validated value.
- class pulpcore.plugin.serializers.FilesystemExporterSerializer(*args, **kwargs)¶
Base serializer for FilesystemExporters.
- class pulpcore.plugin.serializers.IdentityField(*args, **kwargs)¶
IdentityField for use in the pulp_href field of non-Master/Detail Serializers.
The get_url method is overriden so relative URLs are returned.
When a field is instantiated, we store the arguments that were used, so that we can present a helpful representation of the object.
- get_url(obj, view_name, request, *args, **kwargs)¶
Given an object, return the URL that hyperlinks to the object.
May raise a NoReverseMatch if the view_name and lookup_field attributes are not configured to correctly match the URL conf.

Serializer for Imports.
- class pulpcore.plugin.serializers.ImporterSerializer(*args, **kwargs)¶
Base serializer for Importers.
- class pulpcore.plugin.serializers.LabelsField(*args, **kwargs)¶
A serializer field for pulp_labels.
When a field is instantiated, we store the arguments that were used, so that we can present a helpful representation of the object.
- to_internal_value(data)¶
Ensures that data conforms to key/value dict.
- Parameters
data (str or dict) – A dictionary which maps a label key to a label value
- Returns
A validated data dict for labels mapping keys to values
- Raises
rest_framework.serializers.ValidationError – if data is invalid (e.g., not a dict)
- to_representation(labels)¶
Serializes list of labels to a dict.
- Parameters
labels (list of

) – A list of labels to serialize- Returns
A dict that maps label keys to label values

- validate_proxy_url(value)¶
Check, that the proxy_url does not contain credentials.

file://
path, and if so, ensure it’s an ALLOWED_IMPORT_PATH.The ALLOWED_IMPORT_PATH is specified as a Pulp setting.
- Parameters

A serializer for content_types with a single Artifact.
The Artifact can either be specified via it’s url, or a new file can be uploaded. Additionally a repository can be specified, to which the content unit will be added.
When using this serializer, the creation of the real content must be wrapped in a task that locks the Artifact and when specified, the repository.
Initializer for SingleArtifactContentUploadSerializer.
- deferred_validate(data)¶
Validate the content unit by deeply analyzing the specified Artifact.
This is only called when validating without a request context to prevent stalling an ongoing http request. It should be overwritten by plugins to extract metadata from the actual content in much the same way as validate.
- validate(data)¶
Validate that we have an Artifact or can create one.
- class pulpcore.plugin.serializers.SingleContentArtifactField(*args, **kwargs)¶

When a field is instantiated, we store the arguments that were used, so that we can present a helpful representation of the object.
- get_attribute(instance)¶
Returns the field from the instance that should be serialized using this serializer field.
This serializer looks up the list of artifacts and returns only one, if any exist. If more than one exist, it throws and exception because this serializer is being used in an improper context.
- Parameters
instance (
pulpcore.app.models.Content
) – An instance of Content being serialized.- Returns
A single Artifact model related to the instance of Content.
- class pulpcore.plugin.serializers.ValidateFieldsMixin¶
A mixin for validating unknown serializers’ fields.
