Customizing error handling

djangosaml2idp renders a very basic error page if it encounters an error, indicating an error occured, which error, and possibly an extra message. The HTTP status code is dependant on which error occured. It also logs the exception with error severity. You can customize this by using the SAML_IDP_ERROR_VIEW_CLASS setting. Set this to a dotted import path to your custom (class based) view in order to use that one. You’ll likely want this to use your own template and styling to display and error message. If you subclass the provided djangosaml2idp.error_views.SamlIDPErrorView, you have the following variables available for use in the template:

exception

the exception instance that occurred

exception_type

the class of the exception that occurred

exception_msg

the message from the exception (by doing str(exception))

extra_message

if no specific exception given, a message indicating something went wrong, or an additional message next to the exception_msg

The simplest override is to subclass the SamlIDPErrorView and only using your own error template. You can use any Class-Based-View for this; it’s not necessary to subclass the builtin error view. The example project contains a ready to use example of this; uncomment the SAML_IDP_ERROR_VIEW_CLASS setting and it will use a custom view with custom template.
