Goals

Definitions:

• event: a faire, convention, congress or any other kind of meeting
• registered person: someone who said it will attend at the event
• attendee: a person who actually show up (checked in) at the event

Requirements:

• create a new event (DONE)
• create a new registered person manually (DONE)
• associate to an event a list of registered persons, creating them if needed (manually and importing from external sources) (DONE)
• mark registered persons as present (including them in the list of attendees) (DONE)
• execute actions when an attendee shows up or enters/leaves the event (DONE)
• show information and statistics about registered persons, attendees and events (DONE)

Paths

Webapp

These are the path you see in the browser (AngularJS does client-side routing: no request is issued to the web server, during navigation, if not for fetching data and issuing commands):

• /#/events - the list of events
• /#/event/new - edit form to create a new event
• /#/event/:event_id - show information about an existing event (contains the list of registered persons)
• /#/event/:event_id/edit - edit form to modify an existing event
• /#/persons - the list of persons
• /#/person/new - edit form to create a new person
• /#/person/:person_id - show information about an existing person (contains the list of events the person registered for)
• /#/person/:person_id/edit - edit form to modify an existing person
• /#/import/persons - form used to import persons in bulk

Web server

The paths used to communicate with the Tornado web server:

• /events GET - return the list of events
• /events POST - store a new event
• /events/:event_id GET - return information about an existing event
• /events/:event_id POST - update an existing event
• /events/:event_id DELETE - delete an existing event
• /persons GET - return the list of persons
• /persons POST - store a new person
• /persons/:person_id GET - return information about an existing person
• /persons/:person_id POST - update an existing person
• /persons/:person_id DELETE - delete an existing person
• /events/:event_id/persons/:person_id PUT - update the information about a person related to a given event (e.g.: if the person attended)
• /persons/:person_id/events GET - the list of events the person registered for
• /ebcsvpersons POST - csv file upload to import persons

Triggers

Sometimes we have to execute some script in reaction to an event.

In the data/triggers we have a series of directories; scripts inside of them will be executed when the related action was performed on the GUI or calling the controller.

Available triggers:

• update_person_in_event: executed every time a person data in a given event is updated.
• attends: executed only when a person is marked as attending an event.

update_person_in_event and attends will receive these information:

• via environment:
  • NAME
  • SURNAME
  • EMAIL
  • COMPANY
  • JOB
  • PERSON_ID
  • EVENT_ID
  • EVENT_TITLE
• via stdin, a dictionary containing:
  • dictionary old with the old data of the person
  • dictionary new with the new data of the person
  • dictionary event with the event information
  • boolean merged, true if the data was updated

In the data/triggers-available there is an example of script: echo.py.

Database layout

Information are stored in MongoDB. Whenever possible, object are converted into integer, native ObjectId and datetime.

events collection

Stores information about events and persons registered for a given event.

Please notice that information about a person registered for a given event is solely taken from the event.persons entry, and not to the relative entry in the persons collection. This may change in the future (to integrate missing information), but in general it is correct that, editing (or deleting) a person, older information about the partecipation to an event is not changed.

Main field:

• title
• begin-data
• begin-time
• end-date
• end-time
• persons - a list of information about registered persons
  • persons.$.person_id
  • persons.$.attended
  • persons.$.name
  • persons.$.surname
  • persons.$.email
  • persons.$.company
  • persons.$.job
  • persons.$.ebqrcode

persons collection

Basic information about a person:

• persons.name
• persons.surname
• persons.email
• persons.company
• persons.job

TODO

Next to be done

• handle datetimes (on GUI with a calendar and on the backend deserializing ISO 8601 strings)
• modal on event/person removal

Nice to have

• a test suite
• join the page used to add persons/events into the lists (shown when the filter field returns nothing and/or when a button is pressed)
• notifications for form editing and other actions
• authentication for administrators
• i18n
• logging and debugging code
