Description

Add event management in homepage with CRUD option when a user is connected to admin.

A user can select a created event and this will open a session with the event id to manage. Once an event is selected, the project pages change to be linked to this event.

One event is linked to a lot of part of the project, schedule part has been updated to be linked to specific event management, but there is still a lot to do to complete the event management ( to be made in other issues as this one issue embark too many changes already)

• Add speakers attending to an event. => issue #155
• Add organizations sponsoring an event. => issue #156
• Link all sponsorship part to one event only. => issue #157
• Be able to link an organization to become a sponsor with a specific level.

NB: this list can be updated.

I also have an error when trying to go on Schedule page after having selected an event: NoEventSelectedException

This is thrown here, in src/Service/Event/EventService.php (line 68):

    public function getSelectedEvent(): Event
    {
        if ($this->session->has(self::EVENT_ID)) {
            throw new NoEventSelectedException(); // <---
        }

Yeah, missing a "!" :( Commited
