charms.saml_integrator.v0.saml

Library to manage the relation data for the SAML Integrator charm.

This library contains the Requires and Provides classes for handling the relation between an application and a charm providing the samlrelation. It also contains a SamlRelationData class to wrap the SAML data that will be shared via the relation.

Requirer Charm

from charms.saml_integrator.v0 import SamlDataAvailableEvent, SamlRequires

class SamlRequirerCharm(ops.CharmBase):
    def __init__(self, *args):
        super().__init__(*args)
        self.saml = saml.SamlRequires(self)
        self.framework.observe(self.saml.on.saml_data_available, self._handler)
        ...

    def _handler(self, events: SamlDataAvailableEvent) -> None:
        ...

As shown above, the library provides a custom event to handle the scenario in which new SAML data has been added or updated.

Provider Charm

Following the previous example, this is an example of the provider charm.

from charms.saml_integrator.v0 import SamlDataAvailableEvent, SamlRequires

class SamlRequirerCharm(ops.CharmBase):
    def __init__(self, *args):
        super().__init__(*args)
        self.saml = SamlRequires(self)
        self.framework.observe(self.saml.on.saml_data_available, self._on_saml_data_available)
        ...

    def _on_saml_data_available(self, events: SamlDataAvailableEvent) -> None:
        ...

    def __init__(self, *args):
        super().__init__(*args)
        self.saml = SamlProvides(self)

The SamlProvides object wraps the list of relations into a relations property and provides an update_relation_data method to update the relation data by passing a SamlRelationData data object. Additionally, SamlRelationData can be used to directly parse the relation data with the class method from_relation_data.
