Dear [% user.family_name %], [% user.first_given_name %]
The following items are 90 days overdue and have been marked LOST.
[%- params.recipient_email || user.email %][%- params.sender_email || default_sender %]
[% FOR circ IN target %]
  Title: [% circ.target_copy.call_number.record.simple_record.title %]
  Barcode: [% circ.target_copy.barcode %]
  Due: [% date.format(helpers.format_date(circ.due_date), '%Y-%m-%d') %]
  Item Cost: [% helpers.get_copy_price(circ.target_copy) %]
  Total Owed For Transaction: [% circ.billable_transaction.summary.total_owed %]
  Library: [% circ.circ_lib.name %]
[% END %]

[% FOR circ IN target %]
  Title: [% circ.target_copy.call_number.record.simple_record.title %]
  Barcode: [% circ.target_copy.barcode %]
  Due: [% date.format(helpers.format_date(circ.due_date), '%Y-%m-%d') %]
  Item Cost: [% helpers.get_copy_price(circ.target_copy) %]
  Total Owed For Transaction: [% circ.billable_transaction.summary.total_owed %]
  Library: [% circ.circ_lib.name %]
[% END %]

Once you are satisfied with your new event trigger, click the Save button located at the bottom of the form.

Tip

A quick and easy way to create new action triggers is to clone an existing action trigger.

Cloning Existing Action Triggers

Check the check box next to the action trigger you wish to clone.
Click Clone Selected on the top left of the page.
An editing window will open. Notice that the fields will be populated with content from the cloned action trigger. Edit as necessary and give the new action trigger a unique Name.
Click Save.

Editing Action Triggers

Double-click on the action trigger you wish to edit.
The edit screen will appear. When you are finished editing, click Save at the bottom of the form. Or click Cancel to exit the screen without saving.

Note

Before deleting an action trigger, you should consider disabling it through the editing form. This way you can keep it for future use or cloning.

Deleting Action Triggers

Check the check box next to the action trigger you wish to delete
Click Delete Selected on the top-right of the page.

Hooks

Hooks define the Fieldmapper class in the core_type column off of which the rest of the field definitions “hang”.

Table 2. Hooks

Field	Description
Hook Key	A unique name given to the hook.
Core Type	Used to link the action trigger to the IDL class in fm_IDL.xml
Description	Text to describe the purpose of the hook.
Passive	Indicates whether or not an event is created by direct user action or is circumstantial.

You may also create, edit and delete Hooks but the Core Type must refer to an IDL class in the fm_IDL.xml file.

Reactors

Reactors link the trigger definition to the action to be carried out.

Table 3. Action Trigger Reactors

Field	Description
Module Name	The name of the Module to run if the action trigger is validated. It must be defined as a subroutine in `/openils/lib/perl5/OpenILS/Application/Trigger/Reactor.pm` or as a module in `/openils/lib/perl5/OpenILS/Application/Trigger/Reactor/*.pm`.
Description	Description of the Action to be carried out.

You may also create, edit and delete Reactors. Just remember that there must be an associated subroutine or module in the Reactor Perl module.

Validators

Validators set the validation test to be preformed to determine whether the action trigger is executed.

Table 4. Action Trigger Validators

Field	Description
Module Name	The name of the subroutine in `/openils/lib/perl5/OpenILS/Application/Trigger/Reactor.pm` to validate the action trigger.
Description	Description of validation test to run.

You may also create, edit and delete Validators. Just remember that their must be an associated subroutine in the Reactor.pm Perl module.
