Deleting
========
.. _CSRF: https://en.wikipedia.org/wiki/Cross-site_request_forgery
.. _Requests: https://2.python-requests.org/en/master/
The delete action executes the HTTP method DELETE which is usually protected by
CSRF_ and therefore you must make some effort to initialize your HTTP Session
to send DELETE requests acceptable by the remote server.
Let's assume you use the python library Requests_
.. code-block:: python
import pyodata
import requests
SERVICE_URL = 'http://example.io/TheServiceRoot/'
session = requests.Session()
response = session.head(SERVICE_URL, headers={'x-csrf-token': 'fetch'})
token = response.headers.get('x-csrf-token', '')
session.headers.update({'x-csrf-token': token})
theservice = pyodata.Client(SERVICE_URL, session)
Deleting an entity
------------------
You can either delete entity by passing its PropertyRef value to the delete function
.. code-block:: python
request = service.entity_sets.Employees.delete_entity(23)
request.execute()
or by passing the EntityKey object
.. code-block:: python
key = EntityKey(service.schema.entity_type('Employee'), ID=23)
request = service.entity_sets.Employees.delete_entity(key=key)
request.execute()
Encode OData URL Path
-------------------------------------------
By default the resource paths of requests are percent encoded. However if this is not what your API expects,
you can disable the encoding with the variable encode_path by setting it to False.
.. code-block:: python
request = service.entity_sets.Employees.delete_entity(key=key, encode_path=False)
