This feature is implemented partly by the web client invoking the

hosted directly at the base url with respect to its attempts to invoke the

on screen to the user, all subsequent UI activity will have no effect on
the timer, and it will not reset, and the server will not be aware of this
activity. Only a full page load like clicking a link to a new page will
register as activity and reset the timer.


This breakage affects all ''SDS Laravel'' instances at
* resources/js/app.js
https://sdsdev.smus.ca which are in sub-directories.
* resources/views/includes/menu.blade.php
* routes/web.php


The primary change of this task fixes the problem by making the web client

<code><nowiki>url: '{{route('session')}}'</nowiki></code> rather than

<code>url: '/session'</code>.
 
An additional change of this task is to fix a problem where the
app's background image doesn't display for the same underlying reason. The
problem is that the web client is trying to load the image

updates 1 line in the CSS file <code>public/css/smus_custom.css</code> to
<code>background: url('../images/body.png')</code> from
<code>background: url('/images/body.png')</code>; the newly-relative url is
relative to the location of the CSS file itself.
 
There is still additional broken behavior related to static asset loading
like the background image example, affecting custom fonts for example, but
these references are in the generated file <code>public/css/app.css</code>
as parts of third-party dependencies, and so these were left alone.
 
== SDS Laravel: Internal Design Changes ==
 
=== 2024 May 7: Replace model attrs "dates" with "casts" ===
 
Laravel supported a "dates" model attribute through version 9, and then
Laravel 10 removed it. The function of this was to enumerate database/model
fields that were supposed to be automatically converted to Carbon DateTime
objects; so under Laravel 8, any "dates" declarations would be respected,
while under Laravel 10 they would be ignored.
 
Compare:
 
* https://laravel.com/api/9.x/Illuminate/Database/Eloquent/Concerns/HasAttributes.html
* https://laravel.com/api/10.x/Illuminate/Database/Eloquent/Concerns/HasAttributes.html
 
As a result, simply upgrading ''SDS Laravel'' from Laravel 8 to 10 resulted
in many parts of the app breaking in various ways including when simply
visiting the post-login home screen, as PHP died with errors like
<code>Call to a member function format() on int</code>.
 
To fix this, any instances of <code>protected $dates = ['x',...]</code>
in model classes were replaced with
<code>protected $casts = ['x'=>'datetime',...]</code>
which was the more modern way to get the same functionality, which exists
in both Laravel 8 and 10. For the few model classes that already had other
<code>$casts</code> declarations, the replacements were merged with those.
 
The changes of this task were not merged to trunk yet because it was deemed
important to give each instance of the changed 51 model classes more
thorough testing before merging than they had received as of 2024 May 7.
One key reason for this is the idea that the fields in question might not
all be date+time, and rather may be date-only or time-only.
All ''SDS Laravel'' screens accessible from a main menu item were found to
load and at a glance seemed to display correctly, with these changes
included, but that is as far as any testing went as of 2024 May 7.
(There are 2 such screens that didn't load, but they didn't load prior to
these changes either, and that is a separate concern.)
 
As of 2024 May 7, the changes of this task have been bundled with the
changes of the task upgrading ''SDS Laravel'' from Laravel 8 to 10, so the
sum changes would receive the necessary thorough testing together before
being merged to trunk. However, since the changes of this task do not
depend on the upgrade, it is possible that a subset of them may be fully
tested and merged sooner when other changes using the same models occur.
 
[[#top|RETURN]]
 
== SDS Laravel: Changes to Third-Party Dependencies ==
 
=== 2024 May 16: Stop requiring laravel-eloquent-uuid ===
 
''SDS Laravel'' uses serially generated integers in most of its database
tables for their primary key fields, but for a small number of tables it
instead uses generated UUIDs for their primary key fields.
 
Prior to the performance of this task, the third-party PHP library
dependency <code>goldspecdigital/laravel-eloquent-uuid</code> version
<code>v8.0.1</code> was used to empower such UUID use, since Laravel
Eloquent itself did not support these prior to version 9.3. While we can
make use of equivalent functionality built-in to Laravel once we upgrade
to Laravel 10, we can't while we are on Laravel 8.
 
Fundamentally, the feature in question that we use is summed up by a single
very small PHP trait defined in a single file of a few dozen lines of code.
This is the case both for the <code>goldspecdigital</code> version used
prior to this task and the Laravel built-in that can be used later.
 
Here is a description of the built-in feature in Laravel 9.3+:
 
https://laravel.com/docs/11.x/eloquent#uuid-and-ulid-keys
 
Regardless of which of these options is used, most of core UUID-specific
functionality is provided by the third-party PHP library
<code>ramsey/uuid</code>, and Laravel 8+ itself already has this as its own
dependency for other reasons.
 
The primary change of this current task is to clone the single PHP file
from <code>goldspecdigital</code> that we actually use into ''SDS Laravel''
itself, as the new file <code>app/Models/Traits/Uuid.php</code>, and to
update <code>composer.json</code> to remove the explicit external
dependency on <code>goldspecdigital/laravel-eloquent-uuid</code>. In the
process, the fully-qualified PHP trait name was renamed to
<code>App\Models\Traits\Uuid</code> from
<code>GoldSpecDigital\LaravelEloquentUUID\Database\Eloquent\Uuid</code>,
but it had no other changes of any kind.
 
The only 5 other app PHP source files that directly used it were updated to
account for the new name:
 
* app/Models/Application/Application.php
* app/Models/User.php
* app/Models/User/Student.php
* app/Models/User/Teacher.php
* app/Models/User/UserContract.php
 
These further 3 files also referenced the trait but commented out, so not
current users but possible past or future users:
 
* app/Models/Application/AppUser.php
* app/Models/User/Address.php
* app/Models/User/Guardian.php
 
Another change made by this current task was to delete the single PHP file
<code>app/Models/Traits/Uuids.php</code> as it appeared to be unused.
 
Note that <code>goldspecdigital/laravel-eloquent-uuid</code> had a newer
version <code>10.x</code> that was explicitly compatible with Laravel 10,
however a source comparison of the 2 versions found that they were actually
identical in every way aside from adding a half dozen PHP type annotations
in the source code and changing the <code>composer.json</code> to require
Laravel 10 instead of 8.
As such, it was actually the <code>Uuid.php</code> file from version 10
cloned by this task rather than the one from version 8, so we benefitted
from the added PHP type annotations, and the behavior should be identical.
 
The net effect of this task was to maintain exactly the same app behavior
while dropping a hard external dependency, this reducing our overall
complexity and simplifying the later task of upgrading to Laravel 10.
 
It is expected that the future upgrade to Laravel 10 will take the next
step and remove this cloned trait file, and its users will use the
Larvel 10 built-in instead.
 
[[#top|RETURN]]
 
=== 2024 May 3: Upgrade Laravel from 8.x to 10.x ===
 
This task updated <code>composer.json</code> to require the latest
PHP-8.1-compatible major version of the PHP library dependency Laravel from
8.x to 10.x.
 
To be more specific, it made these dependency changes:
 
* barryvdh/laravel-debugbar (^3.7 to ^3.13.5)
* directorytree/ldaprecord-laravel (^2.7.3 unchanged but upgrade exists)
* etern8ty/beanstream (dev-master unchanged but upgrade exists)
* fakerphp/faker (^1.23.1 unchanged)
* fideloper/proxy (^4.4.2 removed as Laravel has its upgrade built-in)
* goldspecdigital/laravel-eloquent-uuid (^8.0.1 to ^10.0)
* guzzlehttp/guzzle (^7.8.1 unchanged)
* intervention/image (^2.7.2 unchanged but upgrade exists)
* juliomotol/laravel-auth-timeout (^3.1.1 to ^4.1)
* lab404/laravel-impersonate (^1.7.5)
* laravel/framework (^8.83.27 to ^10.48.10)
* laravel/helpers (^1.7 unchanged but possibly no longer needed)
* laravel/pint (^1.15.3 added but not yet used)
* laravel/sail (^1.29.1 added but not yet used)
* laravel/sanctum (^3.3.3 added but not yet used)
* laravel/tinker (^2.9 unchanged)
* laravel/ui (^3.4.6 to 4.5.1)
* mockery/mockery (^1.6.11 unchanged)
* nunomaduro/collision (^5.11 to ^7.10)
* phpunit/phpunit (^10.5.20 unchanged)
* spatie/laravel-ignition (^1.6.4 to ^2.7)
* staudenmeir/eloquent-has-many-deep (^1.14.4 to ^1.19.3)
 
Note that <code>juliomotol/laravel-auth-timeout</code> version 4.1 requires
Laravel version 9 or greater so it can not be upgraded from 3.1.1 prior to
the Laravel 10 upgrade.
 
This task also updated <code>app/Http/Middleware/TrustProxies.php</code> to
be compatible with the replacement of <code>fideloper/proxy</code> with a
Laravel built-in. The changes were in 2 spots.
 
First was this substitution:
 
    use Fideloper\Proxy\TrustProxies as Middleware;
 
    use Illuminate\Http\Middleware\TrustProxies as Middleware;
 
Second was this substitution:
 
    protected $headers = Request::HEADER_X_FORWARDED_ALL;
 
    protected $headers =
        Request::HEADER_X_FORWARDED_FOR |
        Request::HEADER_X_FORWARDED_HOST |
        Request::HEADER_X_FORWARDED_PORT |
        Request::HEADER_X_FORWARDED_PROTO |
        Request::HEADER_X_FORWARDED_AWS_ELB;
 
This task also updated
<code>app/Http/Middleware/AuthTimeoutMiddleware.php </code> to be
compatible with the <code>juliomotol/laravel-auth-timeout</code> upgrade.
 
There was this 1 substitution:
 
    use JulioMotol\AuthTimeout\Middleware\AuthTimeoutMiddleware as BaseMiddleware;
 
    use JulioMotol\AuthTimeout\Middlewares\CheckAuthTimeout as BaseMiddleware;
 
This task also explored upgrades to some other PHP library dependencies but
they were excluded due to requiring more substantial  code changes for
compatibility, and will be returned to later.

This document consists of multiple parts; for a directory to all of the parts, see SDSM:Index.

Description

This part of the SDS Modernization (SDSM) document enumerates a not necessarily exhaustive list of pending changes or improvements that were made to SDS, made by Darren Duncan if by whom is not otherwise specified.

It is similar to the Historical Changes part but that it describes work which was prepared and published in Git feature branches that are longer lived and not yet merged to the trunk; in contrast, Historical is for work that was merged to trunk.

SDS Laravel: Removed Application Functionality

2024 Jun 25: Remove Screens For Application For Student Enrollment By Parents

This task removed the SDS Laravel screens that supported parents applications for student enrollment of their children directly in SDS. The functionality became obsolete and unused when Blackbaud started being used for applications instead, and applications were imported to SDS from Blackbaud by an automated process.

These 20 source files were simply removed:

  • app/Http/Controllers/Application/ApplicationController.php
  • app/Http/Controllers/Application/FamilyInfoController.php
  • app/Http/Controllers/Application/OtherController.php
  • app/Http/Controllers/Application/ParentInfoController.php
  • app/Http/Controllers/Application/ParentQuestionController.php
  • app/Http/Controllers/Application/StudentInfoController.php
  • app/Http/Controllers/Application/StudentQuestionController.php
  • app/Http/Controllers/System/EditBoardingQuestionController.php
  • resources/js/components/application/AddressInfo.vue
  • resources/js/components/application/FamilyStatus.vue
  • resources/js/components/application/GuardianHolder.vue
  • resources/js/components/application/GuardianInfo.vue
  • resources/views/application/home.blade.php
  • resources/views/application/index.blade.php
  • resources/views/application/parentinfo/index.blade.php
  • resources/views/application/studentinfo/index.blade.php
  • resources/views/includes/application_menu.blade.php
  • resources/views/system/boarding_question/create.blade.php
  • resources/views/system/boarding_question/edit.blade.php
  • resources/views/system/boarding_question/index.blade.php

These 3 source files were updated to remove references to the removed ones:

  • resources/js/app.js
  • resources/views/includes/menu.blade.php
  • routes/web.php

Note that Laravel Eloquent Models related to this functionality were explicitly left alone, so they can still thoroughly represent the actual database structure, and they can still be used by other processes. Likewise, references to student applications in other screens were left alone as they may still be relevant to the Blackbaud process or for history.
