When using an invalid letter model, the notification will not be generated and will not appear as failed in the message_queue table. There is no way to see that a notification has failed to generate (except by knowing he has requested a notice that has not appeared, it is easy for welcome as it is manual but way harder for DUE, PPREDUE, ... that are automaticly generated). Step to reproduce : 1- Select a borrower with an email address (primay email, no need to be a valid one) 2- On the detail page of the patron, click on "More" then "Send welcoe notice" 3- In tab Notices, check that it is generated correctly (default model) 4- Go to Tools > Notices and slip 5- Update the notice WELCOME with the following model ``` Welcome [% borrower.date_due %] ``` No warning is generated on the interface when saving 6- Repeat step 2 7- No notice is generated, no interface warning/error/message is generated, no log error either : the librarian has no way of knowing that it has failed !
The only case where I got some log is when the TT error is in a notice generated by a cronjob (advances_notices.pl, PREDUEDGST), I got the follwing error by an email report of the cron : ``` ERROR PROCESSING TEMPLATE: undef error - The method Koha::Item->date_due is not covered by tests!
