Installation and usage

This package can be installed directly from GitHub using pip:

pip install git+https://github.com/Princeton-CDH/htr2hpc.git@main#egg=htr2hpc

pucas is a dependency of this package and will be included when you install this package.

Import htr2hpc settings into the deployed escriptorium local settings. It must be imported after escriptorium settings so that overrides take precedence.

from escriptorium.settings import *
from htr2hpc.settings import *

This adjusts the settings as follows:

• Adds to INSTALLED_APPS and AUTHENTICATION_BACKENDS and provides a basic PUCAS_LDAP configuration to enable Princeton CAS authentication; configures CAS_REDIRECT_URL to use the escriptorium LOGIN_REDIRECT_URL configuration (currently the projects list page) and sets CAS_IGNORE_REFERER = True to avoid behavior where successful CAS login takes you back to the login page
• Sets ROOT_URLCONF to use htr2hpc.urls, which adds pucas url paths to the urls defined in escriptorium.urls
• Adds htr2hpc/templates directory first in the list of template directories, so that any templates in this application will take precedence over eScriptorium templates; currently used for customizing the login page to add Princeton CAS login

Configure CAS authentication

To fully enable CAS, you must fill out configurations for CAS server url and PUCAS LDAP settings in the local settings of your deployed application.

from escriptorium.settings import *
from htr2hpc.settings import *

# CAS login configuration
CAS_SERVER_URL = "https://example.com/cas/"

PUCAS_LDAP.update(
    {
        "SERVERS": [
            "ldap2.example.com",
        ],
        "SEARCH_BASE": "",
        "SEARCH_FILTER": "(uid=%(user)s)",
        # other ldap attributes as needed
    }
)
