These days I have been working in the assign tickets to the person in charge section. To do this I had to make some methods:

AssignTicketsForm: This one goes in forms.py.

AssignTickets: This one goes in views.py.

In general, the function of these methods is to set the person in charge of selling these tickets. A screen with all the current tickets of the event will appear and a field where the user can write the name of the seller. This will be saved in the seller variable of the ticket. The user can select all the tickets that will be under his charge by using the Ctrl key.
