Usage

This plugin will add core facilities and custom charges which can be added through django admin.

Core Facility can be set on Custom Charges, Tools, Areas, Consumables and Staff Charges

There are 2 ways to set them up:

In Detailed Administration -> Core Facilities, you can select each tool, area, consumable or staff charge
In Detailed Administration -> NEMO on each individual custom charge, tool, area, consumable or staff charge

Core Facility can be accessed on a tool, area, consumable or staff charge using: tool.core_facility, area.core_facility, consumable.core_facility or staff_charge.core_facility

Options

By default, a Core Facility is not required for each custom charge, tool, area, consumable or staff charge.

That can be changed by updating the following default settings in settings.py:

TOOL_CORE_FACILITY_REQUIRED = False
AREA_CORE_FACILITY_REQUIRED = False
CONSUMABLE_CORE_FACILITY_REQUIRED = False
STAFF_CHARGE_CORE_FACILITY_REQUIRED = False
CUSTOM_CHARGE_CORE_FACILITY_REQUIRED = False

In the billing (user, project billing, billing API, invoices) tool usage and area access on behalf of a user (only during a remote project) are categorized as Staff Charges.

That can be changed by updating the following default settings in settings.py

STAFF_TOOL_USAGE_AS_STAFF_CHARGE = True
STAFF_AREA_ACCESS_AS_STAFF_CHARGE = True

Email templates

To change email templates, either go to Invoices customization settings in NEMO and upload new files, or directly create a file in NEMO's media folder with the same name.
The following templates can be set:

email_send_invoice_subject.txt
email_send_invoice_message.html
email_send_invoice_reminder_subject.txt
email_send_invoice_reminder_message.html
billing_project_expiration_reminder_email_subject.txt
billing_project_expiration_reminder_email_message.html

Timed services/cron jobs

To send reminder emails, set a cron job daily with one of the 2 options:

send an authenticated http request to <nemo_url>/invoices/send_invoice_payment_reminder
run command django-admin send_invoice_payment_reminder or python manage.py send_invoice_payment_reminder

Similarly, to automatically deactivate expired projects and send expiration reminders, set a cron job daily with one of the 2 options:

send an authenticated http request to <nemo_url>/projects/deactivate_expired_projects
run command django-admin deactivate_expired_projects or python manage.py deactivate_expired_projects
