isogeo_pysdk.api.routes_link module¶

Isogeo API v1 - API Routes to manage metadata links.

See: http://help.isogeo.com/api/complete/index.html

class isogeo_pysdk.api.routes_link.ApiLink(api_client=None)[source]¶

Bases: object

Routes as methods of Isogeo API used to manipulate metadata links (CGUs).

clean_kind_action_liability[source]¶

Link available actions depend on link kind. Relationships between kinds and actions are described in the /link-kinds route. This is a helper checking the liability between kind/actions/type and cleaning if needed. Useful before creating or updating a link.

Parameters:	link_actions (list) – link actions link_kind (str) – link kind
Return type:	tuple
Example:

# invalid action will be removed
print(isogeo.metadata.links.clean_kind_action_liability(
    link_actions=("download", "stream"),
    link_kind="url"
    )
)
>>> ('download',)

create(metadata: isogeo_pysdk.models.metadata.Metadata, link: isogeo_pysdk.models.link.Link) → isogeo_pysdk.models.link.Link[source]¶

Add a new link to a metadata (= resource).

Parameters:	metadata (Metadata) – metadata (resource) to edit link (Link) – link object to create
Returns:	the created link or a tuple with the request’s response error code
Return type:	Link or tuple
Example:

# retrieve metadata
md = isogeo.metadata.get(METADATA_UUID)
# create the link locally
new_link = Link(
    type="url",
    restriction="patent",
    description="Do not use for commercial purpose.",
    )
# add it to the metadata
isogeo.metadata.links.create(md, new_link)

# to create a link which is a pointer to another link, add the link attribute:
new_link = Link(
    actions=["other"],
    title="Associated link",
    kind="url",
    type="link",
    link=Link(_id=LINK_UUID)
    )

delete(link: isogeo_pysdk.models.link.Link, metadata: isogeo_pysdk.models.metadata.Metadata = None) → requests.models.Response[source]¶

Delete a link from a metadata.

Parameters:	link (Link) – Link model object to delete metadata (Metadata) – parent metadata (resource) containing the link. Optional if the link contains the ‘parent_resource’ attribute.
Return type:	Response

download_hosted(link: isogeo_pysdk.models.link.Link, encode_clean: bool = 1) → tuple[source]¶

Download hosted resource.

Parameters:	link (Link) – link object encode_clean (bool) – option to ensure a clean filename and avoid OS errors
Returns:	tuple(stream, filename, human readable size)
Return type:	tuple

Example:

# get links from a metadata
md_links = isogeo.metadata.links.listing(Metadata(_id=METADATA_UUID))
# filter on hosted links
hosted_links = [
    link for link in md_links
    if link.get("type") == "hosted"
    ]
# get the stream, the filename and the size (in human readable format)
dl_stream = isogeo.metadata.links.download_hosted(Link(**hosted_links[0]))
# download the file and store it locally
with open("./" + dl_stream[1], "wb") as fd:
    for block in dl_stream[0].iter_content(1024):
        fd.write(block)

get[source]¶

Get details about a specific link.

Parameters:	metadata_id (str) – metadata UUID link_id (str) – link UUID
Return type:	Link
Example:

# get a metadata
md = isogeo.metadata.get(METADATA_UUID)
# list its links
md_links = isogeo.metadata.links.listing(md)
# get the first link
link = isogeo.metadata.links.get(
    metadata_id=md._id,
    link_id=md_links[0].get("_id")
    )

kinds_actions[source]¶

Get the relation between kinds and action for links.

Parameters:	caching (bool) – cache the response into the main API client instance. Defaults to True.
Returns:	list of dictionaries per link kinds
Return type:	list
Example:

import pprint
pprint.pprint(isogeo.metadata.links.kinds_actions())

>>> [
        {
            'actions':
            [
                'download',
                'view',
                'other'
            ],
            'kind': 'url',
            'name': 'Lien'
        },
        {
            'actions': ['download', 'view', 'other'],
            'kind': 'wfs',
            'name': 'Service WFS'
        },
        {

        },

        },

Update a link.

Parameters:	link (Link) – Link model object to update metadata (Metadata) – parent metadata (resource) containing the link. Optional if the link contains the ‘parent_resource’ attribute.

upload_hosted(metadata: isogeo_pysdk.models.metadata.Metadata, link: isogeo_pysdk.models.link.Link, file_to_upload: str) → isogeo_pysdk.models.link.Link[source]¶
