Example Script

Working with files

"""
Expects that ~/temp exists and is a directory.

The purpose of this script is to demonstrate how to use the new OOP interface for files.
The following actions are shown in this script:
1. Creating a file
2. Storing a file
3. Storing a file in a sub-folder
4. Renaming a file
5. Downloading a file
6. Deleting a file
7. Copying a file
8. Storing an activity to a file
9. Retrieve an activity from a file

API Reference

synapseclient.models.File dataclass

Bases: FileSynchronousProtocol, AccessControllable

A file within Synapse.

ATTRIBUTE	DESCRIPTION
id	The unique immutable ID for this file. A new ID will be generated for new Files. Once issued, this ID is guaranteed to never change or be re-issued. TYPE: Optional[str]
name	The name of this entity. Must be 256 characters or less. Names may only contain: letters, numbers, spaces, underscores, hyphens, periods, plus signs, apostrophes, and parentheses. If not specified, the name will be derived from the file name. TYPE: Optional[str]
path	The path to the file on disk. Using shorthand ~ will be expanded to the user's home directory. This is used during a get operation to specify where to download the file to. It should be pointing to a directory. This is also used during a store operation to specify the file to upload. It should be pointing to a file. TYPE: Optional[str]
description	The description of this file. Must be 1000 characters or less. TYPE: Optional[str]
parent_id	The ID of the Entity that is the parent of this Entity. Setting this to a new value and storing it will move this File under the new parent. TYPE: Optional[str]
version_label	The version label for this entity. Updates to the entity will increment the version number. TYPE: Optional[str]
version_comment	The version comment for this entity TYPE: Optional[str]
data_file_handle_id	ID of the file associated with this entity. You may define an existing data_file_handle_id to use the existing data_file_handle_id. The creator of the file must also be the owner of the data_file_handle_id to have permission to store the file. TYPE: Optional[str]
external_url	The external URL of this file. If this is set AND synapse_store is False, only a reference to this URL and the file metadata will be stored in Synapse. The file itself will not be uploaded. If this attribute is set it will override the path. TYPE: Optional[str]
activity	The Activity model represents the main record of Provenance in Synapse. It is analygous to the Activity defined in the W3C Specification on Provenance. Activity cannot be removed during a store operation by setting it to None. You must use: synapseclient.models.Activity.delete_async or [synapseclient.models.Activity.disassociate_from_entity_async][]. TYPE: Optional[Activity]
annotations	Additional metadata associated with the folder. The key is the name of your desired annotations. The value is an object containing a list of values (use empty list to represent no values for key) and the value type associated with all values in the list. To remove all annotations set this to an empty dict {} or None and store the entity. TYPE: Optional[Dict[str, Union[List[str], List[bool], List[float], List[int], List[date], List[datetime]]]]

ATTRIBUTE	DESCRIPTION
content_type	(New Upload Only) Used to manually specify Content-type header, for example 'application/png' or 'application/json; charset=UTF-8'. If not specified, the content type will be derived from the file extension. This can be specified only during the initial store of this file or any time there is a new file to upload. In order to change this after the File has been created use synapseclient.models.File.change_metadata. TYPE: Optional[str]
content_size	(New Upload Only) The size of the file in bytes. This can be specified only during the initial creation of the File. This is also only applicable to files not uploaded to Synapse. ie: synapse_store is False. TYPE: Optional[int]

ATTRIBUTE	DESCRIPTION
content_md5	(Store only) The MD5 of the file is known. If not supplied this will be computed in the client is possible. If supplied for a file entity already stored in Synapse it will be calculated again to check if a new upload needs to occur. This will not be filled in during a read for data. It is only used during a store operation. To retrieve the md5 of the file after read from synapse use the .file_handle.content_md5 attribute. TYPE: Optional[str]
create_or_update	(Store only) Indicates whether the method should automatically perform an update if the file conflicts with an existing Synapse object. TYPE: bool
force_version	(Store only) Indicates whether the method should increment the version of the object if something within the entity has changed. For example updating the description or name. You may set this to False and an update to the entity will not increment the version. Updating the version_label attribute will also cause a version update regardless of this flag. An update to the MD5 of the file will force a version update regardless of this flag. TYPE: bool
is_restricted	(Store only) If set to true, an email will be sent to the Synapse access control team to start the process of adding terms-of-use or review board approval for this entity. You will be contacted with regards to the specific data being restricted and the requirements of access. This may be used only by an administrator of the specified file. TYPE: bool
merge_existing_annotations	(Store only) Works in conjunction with create_or_update in that this is only evaluated if create_or_update is True. If this entity exists in Synapse that has annotations that are not present in a store operation, these annotations will be added to the entity. If this is False any annotations that are not present within a store operation will be removed from this entity. This allows one to complete a destructive update of annotations on an entity. TYPE: bool
associate_activity_to_new_version	(Store only) Works in conjunction with create_or_update in that this is only evaluated if create_or_update is True. When true an activity already attached to the current version of this entity will be associated the new version during a store operation if the version was updated. This is useful if you are updating the entity and want to ensure that the activity is persisted onto the new version the entity. TYPE: bool
synapse_store	(Store only) Whether the File should be uploaded or if false: only the path should be stored when synapseclient.models.File.store is called. TYPE: bool

ATTRIBUTE	DESCRIPTION
download_file	(Get only) If True the file will be downloaded. TYPE: bool
if_collision	(Get only) Determines how to handle file collisions. Defaults to "keep.both". May be: overwrite.local keep.local keep.both TYPE: str
synapse_container_limit	(Get only) A Synanpse ID used to limit the search in Synapse if file is specified as a local file. That is, if the file is stored in multiple locations in Synapse only the ones in the specified folder/project will be returned. TYPE: Optional[str]

ATTRIBUTE	DESCRIPTION
etag	(Read Only) Synapse employs an Optimistic Concurrency Control (OCC) scheme to handle concurrent updates. Since the E-Tag changes every time an entity is updated it is used to detect when a client's current representation of an entity is out-of-date. TYPE: Optional[str]
created_on	(Read Only) The date this entity was created. TYPE: Optional[str]
modified_on	(Read Only) The date this entity was last modified. TYPE: Optional[str]
created_by	(Read Only) The ID of the user that created this entity. TYPE: Optional[str]
modified_by	(Read Only) The ID of the user that last modified this entity. TYPE: Optional[str]
version_number	(Read Only) The version number issued to this version on the object. TYPE: Optional[int]
is_latest_version	(Read Only) If this is the latest version of the object. TYPE: Optional[bool]
file_handle	(Read Only) The file handle associated with this entity. TYPE: Optional[FileHandle]

Functions

get

get(include_activity: bool = False, *, synapse_client: Optional[Synapse] = None) -> File

Get the file from Synapse. You may retrieve a File entity by either:

• id
• path

If you specify both, the id will take precedence.

If you specify the path and the file is stored in multiple locations in Synapse only the first one found will be returned. The other matching files will be printed to the console.

You may also specify a version_number to get a specific version of the file.

PARAMETER	DESCRIPTION
include_activity	If True the activity will be included in the file if it exists. TYPE: bool DEFAULT: False
synapse_client	If not passed in and caching was not disabled by Synapse.allow_client_caching(False) this will use the last created instance from the Synapse class constructor. TYPE: Optional[Synapse] DEFAULT: None

RETURNS	DESCRIPTION
File	The file object.

RAISES	DESCRIPTION
ValueError	If the file does not have an ID or path to get.
