Core API

You can use pyuploadcare in any Python project. At first you need assign your project keys to conf object. After that you will be able to do direct api calls or use api resources:

>>> import pyuploadcare
>>> pyuploadcare.conf.pub_key = '<your public key>'
>>> pyuploadcare.conf.secret = '<your private key>'
>>> f = pyuploadcare.File('6c5e9526-b0fe-4739-8975-72e8d5ee6342')
>>> f.cdn_url
https://ucarecdn.com/6c5e9526-b0fe-4739-8975-72e8d5ee6342/

File API Resource

class pyuploadcare.api_resources.File(cdn_url_or_file_id)

File resource for working with user-uploaded files.

It can take file UUID or group CDN url:

>>> file_ = File('a771f854-c2cb-408a-8c36-71af77811f3b')
>>> file_.cdn_url
https://ucarecdn.com/a771f854-c2cb-408a-8c36-71af77811f3b/
>>> print File('https://ucarecdn.com/a771f854-c2cb-408a-8c36-71af77811f3b/-/effect/flip/')
https://ucarecdn.com/a771f854-c2cb-408a-8c36-71af77811f3b/-/effect/flip/
uuid

File UUID [1], e.g. a771f854-c2cb-408a-8c36-71af77811f3b.

default_effects

String of default effects that is used by File.cdn_url, e.g. effect/flip/-/effect/mirror/.

class FileFromUrl(token)

Contains the logic around an upload from url.

It expects uploading token, for instance:

>>> ffu = FileFromUrl(token='a6a2db73-2aaf-4124-b2e7-039aec022e18')
>>> ffu.info()
{
    "status': "progress",
    "done": 226038,
    "total": 452076
}
>>> ffu.update_info()
{
    "status": "success",
    "file_id": "63f652fd-3f40-4b54-996c-f17dc7db5bf1",
    "is_stored": false,
    "done": 452076,
    "uuid": "63f652fd-3f40-4b54-996c-f17dc7db5bf1",
    "original_filename": "olympia.jpg",
    "is_image": true,
    "total": 452076,
    "size": 452076
}
>>> ffu.get_file()
<uploadcare.File 63f652fd-3f40-4b54-996c-f17dc7db5bf1>

But it could be failed:

>>> ffu.update_info()
{
    "status": "error",
    "error": "some error message"
}
get_file()

Returns File instance if upload is completed.

info()

Returns actual information about uploading as dict.

First time it makes API request to get information and keeps it for further using.

update_info()

Updates and returns information by requesting Uploadcare API.

wait(timeout=30, interval=0.3, until_ready=False)
File.cdn_path(effects=None)
File.cdn_url

Returns file’s CDN url.

Usage example:

>>> file_ = File('a771f854-c2cb-408a-8c36-71af77811f3b')
>>> file_.cdn_url
https://ucarecdn.com/a771f854-c2cb-408a-8c36-71af77811f3b/

You can set default effects:

>>> file_.default_effects = 'effect/flip/-/effect/mirror/'
>>> file_.cdn_url
https://ucarecdn.com/a771f854-c2cb-408a-8c36-71af77811f3b/-/effect/flip/-/effect/mirror/
classmethod File.construct_from(file_info)

Constructs File instance from file information.

For example you have result of /files/1921953c-5d94-4e47-ba36-c2e1dd165e1a/ API request:

>>> file_info = {
        # ...
        'uuid': '1921953c-5d94-4e47-ba36-c2e1dd165e1a',
        # ...
    }
>>> File.construct_from(file_info)
<uploadcare.File 1921953c-5d94-4e47-ba36-c2e1dd165e1a>
File.copy(effects=None, target=None)

Creates a File Copy on Uploadcare or Custom Storage.

File.copy method is deprecated and will be removed in 4.0.0. Please use create_local_copy and create_remote_copy instead.

Args:
  • effects:
    Adds CDN image effects. If self.default_effects property is set effects will be combined with default effects.
  • target:
    Name of a custom storage connected to your project. Uploadcare storage is used if target is absent.
File.create_local_copy(effects=None, store=None)

Creates a Local File Copy on Uploadcare Storage.

Args:
  • effects:
    Adds CDN image effects. If self.default_effects property is set effects will be combined with default effects.
  • store:
    If store option is set to False the copy of your file will be deleted in 24 hour period after the upload. Works only if autostore is enabled in the project.
File.create_remote_copy(target, effects=None, make_public=None, pattern=None)

Creates file copy in remote storage.

Args:
  • target:
    Name of a custom storage connected to the project.
  • effects:
    Adds CDN image effects to self.default_effects if any.
  • make_public:
    To forbid public from accessing your files on the storage set make_public option to be False. Default value is None. Files have public access by default.
  • pattern:
    Specify pattern option to set S3 object key name. Takes precedence over pattern set in project settings. If neither is specified defaults to ${uuid}/${filename}${effects}${ext}.

For more information on each of the options above please refer to REST API docs https://uploadcare.com/documentation/rest/#file.

Following example copies a file to custom storage named samplefs:

>>> file = File('e8ebfe20-8c11-4a94-9b40-52ecad7d8d1a')
>>> file.create_remote_copy(target='samplefs',
>>>                         make_public=True,
>>>                         pattern='${uuid}/${filename}${ext}')

Now custom storage samplefs contains publicly available file with original filename billmurray.jpg in in the directory named e8ebfe20-8c11-4a94-9b40-52ecad7d8d1a.

[<uploadcare.File 6c5e9526-b0fe-4739-8975-72e8d5ee6342>, None]
>>> file_group[0]
<uploadcare.File 6c5e9526-b0fe-4739-8975-72e8d5ee6342>
>>> len(file_group)

File List API Resource

class pyuploadcare.api_resources.FileList(*args, **kwargs)

List of File resources.

This class provides iteration over all uploaded files.

You can specify:

  • starting_point – a starting point for filtering files. It is reflects a from parameter from REST API.
  • ordering – a string with name of the field what must be used for sorting files. The actual list of supported fields you can find in documentation: http://uploadcare.com/documentation/rest/#file-files
  • limit – a total number of objects to be iterated. If not specified, all available objects are iterated;
  • request_limit – a number of objects retrieved per request (page). Usually, you don’t need worry about this parameter.
  • storedTrue to include only stored files, False to exclude, None is default, will not exclude anything;
  • removedTrue to include only removed files, False to exclude, None will not exclude anything. The default is False.

Files can’t be stored and removed at the same time, such query will always return an empty set.

But files can be not stored and not removed (just uploaded files).

Usage example:

>>> for f in FileList(removed=None):
>>>     print(f.datetime_uploaded())

Count objects:

>>> print('Number of stored files is', FileList(stored=True).count())
api_url(**qs)
base_url = u'/files/'

  • ordering – a string with name of the field what must be used for sorting files. The actual list of supported fields you can find in documentation: https://uploadcare.com/documentation/rest/#group-groups
  • limit – a total number of objects to be iterated. If not specified, all available objects are iterated;
  • request_limit – a number of objects retrieved per request (page). Usually, you don’t need worry about this parameter.

Usage example:

>>> from datetime import datetime, timedelta
>>> last_week = datetime.now() - timedelta(weeks=1)
>>> for f in GroupList(starting_point=last_week):
>>>     print(f.datetime_created())
