[jeremysteerio]

UHF-10259

Add backend files for curated event list paragraph.

Sketch: https://www.figma.com/design/v5YC5vwdlXr1N8RaZ9SMPO/Hel.fi-Ajankohtaissis%C3%A4ll%C3%B6t-(Uutiset)?node-id=3261-57157

What was done

• Add new paragraph: curated_event_list
• Add new external entity for Linked Events events
• Add new storageclient for retrieving events
• Add custom constraint and validator
• Add translations

How to install

Install this branch:

• composer require drupal/helfi_platform_config:dev-UHF-10259-curated-event-list
• Run drush updb -y. This should install the new paragraph module.
• Run drush cr

Install the HDBT branch:

• composer require drupal/hdbt:dev-UHF-10259-curated-event-list
• Run drush cr

Import translations:

• Run drush locale:check && drush locale:update
• Run drush cr

How to test

Known issues / deviations from the sketch

• Link icon within the event title/link is the one we usually use. Discussion about this / possible jira ticket upcoming
• Time is displayed in the format we use, d.m.Y H:i and JS locale string format as in sketch. Confirming with design / writing a ticket about this as well.

Event testing:

• Add a new landing page. You should see curated event list option in the list for available paragraph types for content field.
• Add events to the paragraph. You may do this by searching a name and letting autocompletion find the for you. You may also search event by ID. See field instructions for more info.
• View the page. The paragraph layout should match the sketch.

Try you some event combinations. These restrictions should apply:

• You can't add and event that is past its end time. You can test the validation by typing elo:32916e77-a2fc-4b4b-a605-c84b680bd4c5 in the event search field and choosing the event found. If you try to save the page with this selection, the validation fails it and shows an error message.
• Only the top 3 events should be displayed, based on how you order them in the admin
• This is hard to test, but once an added event is past its end time, it should be hidden in the view

Multilingual support:

• Translations of events are loaded dynamically IF those are present in the source data. This is a bit confusing to test since source data has "translations" that are actually the same title in fi, sv and en. You can add event helsinki:agif33o4ui to the list and translate the node to fi / en versions. When viewing the page and switching between translations, you should see event name change accordingly.

Also:

• View all -link should work with default settings. You should be able to change the link text and href.
• Check that code quality matches our standards.

Continuous documentation

• This feature has been documented/the documentation has been updated

Functionality works nicely, needs someone with more backend expertise to review the code.
