Resource Classes

Resource Classes#

The Classes resource represents the classes a school user is a member of.

The resource objects are represented as group objects in the LDAP.

Classes can be created, retrieved, modified, deleted and searched for with the Kelvin API.

Retrieve#

Example curl command to retrieve the class Democlass at DEMOSCHOOL

$ curl  -X GET  "https://<fqdn>/ucsschool/kelvin/v1/classes/DEMOSCHOOL/Democlass" \
        -H "accept: application/json"
        -H "Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciO..."

The response headers will be:

Connection: Keep-Alive
Content-length: 460
Content-type: application/json
Date: Tue,10 May 2022 07:55:51 GMT
Keep-alive: timeout=5,max=100
Server: uvicorn
Via: 1.1 <fqdn>

The response body will be:

{
    "dn": "cn=DEMOSCHOOL-Democlass,cn=klassen,cn=schueler,cn=groups,ou=DEMOSCHOOL,dc=******,dc=******",
    "url": "https://<fqdn>/ucsschool/kelvin/v1/classes/DEMOSCHOOL/Democlass",
    "ucsschool_roles": [
        "school_class:school:DEMOSCHOOL"
    ],
    "udm_properties": {},
    "name": "Democlass",
    "school": "https://<fqdn>/ucsschool/kelvin/v1/schools/DEMOSCHOOL",
    "description": null,
    "users": [
        "https://<fqdn>/ucsschool/kelvin/v1/users/demo_student"
    ],
    "create_share": true
}

Matching of the queried class and school is case-insensitive. The response body will be identical to the response in the example above, if a school only has a single class registered. Otherwise the list of classes from the example above will contain the class which has been requested.

Modify#

Example curl command to modify the class Democlass2 at DEMOSCHOOL

$ curl  -X PATCH  "https://<fqdn>/ucsschool/kelvin/v1/classes/Demoschool/Democlass2" \
        -H "accept: application/json" \
        -H "Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1N..." \
        -H "Content-Type: application/json" \
        -d "{
            "name": "Democlass_2"
        }"

The response headers will be:

HTTP/1.1 200 OK
Connection: Keep-Alive
Content-length: 397
Content-type: application/json
Date: Tue,10 May 2022 07:49:13 GMT
Keep-alive: timeout=5,max=100
Server: uvicorn
Via: 1.1 <fqdn>

The response will be:

{
    "dn": "cn=Demoschool-Democlass_2,cn=klassen,cn=schueler,cn=groups,ou=Demoschool,dc=******,dc=******",
    "url": "https://<fqdn>/ucsschool/kelvin/v1/classes/Demoschool/Democlass_2",
    "ucsschool_roles": [
    "school_class:school:Demoschool"
    ],
    "udm_properties": {},
    "name": "Democlass_2",
    "school": "https://<fqdn>/ucsschool/kelvin/v1/schools/Demoschool",
    "description": null,
    "users": [],
    "create_share": true
}

The example shows how to rename a certain class. Optionally description, udm_properties and/or users can be modified. But a class objects school or create_share can’t be modified.

Create#

Example curl command to create the class Democlass2 at DEMOSCHOOL

$ curl  -X POST  "https://<fqdn>/ucsschool/kelvin/v1/classes/" \
        -H "accept: application/json" \
        -H "Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1..." \
        -H "Content-Type: application/json" \
        -d "{
        "name": "Democlass2",
            "school": "https://<fqdn>/ucsschool/kelvin/v1/schools/DEMOSCHOOL"
        }"

The response headers will be:

HTTP/1.1 201 CREATED
Connection: Keep-Alive
Content-length: 394
Content-type: application/json
Date: Tue,10 May 2022 07:45:30 GMT
Keep-alive: timeout=5,max=100
Server: uvicorn
Via: 1.1 <fqdn>

The response will be:

{
    "dn": "cn=DEMOSCHOOL-Democlass2,cn=klassen,cn=schueler,cn=groups,ou=DEMOSCHOOL,dc=******,dc=******",
    "url": "https://<fqdn>/ucsschool/kelvin/v1/classes/DEMOSCHOOL/DEMOCLASS_2",
    "ucsschool_roles": [
        "school_class:school:DEMOSCHOOL"
    ],
    "udm_properties": {},
    "name": "Democlass2",
    "school": "https://<fqdn>/ucsschool/kelvin/v1/schools/DEMOSCHOOL",
    "description": null,
    "users": [],
    "create_share": true
}

The queried school has to exist, whilst the class to be created must not exist. To create a class its name and the corresponding school must be provided. Optionally a description, udm_properties, users and/or create_share can be provided on creation.

Delete#

Example curl command to delete the class Democlass2 at DEMOSCHOOL

$ curl  -X DELETE  "https://<fqdn>/ucsschool/kelvin/v1/classes/DEMOSCHOOL/Democlass2" \
        -H "accept: */*" \
        -H "Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9..."

The response headers will be:

HTTP/1.1 204 NO CONTENT
Connection: keep-alive
Date: Tue,10 May 2022 07:38:49 GMT
Keep-alive: timeout=5,max=100
Server: uvicorn
Via: 1.1 <fqdn>

The server responses with 204 (with no body), if a class got deleted successfully. Matching of the queried class and school is case-insensitive.
