Problem with follow button in django.

I have a web-site with database of some events. Registered users should be able to follow this events. I mean there should be a button "Follow" on an event page. Users who clicked it should see this event on their home page. But i just cant understand how it should work...

There is event model:

class Event(models.Model):name = models.CharField(max_length=26)second_name = models.CharField(max_length=60)description = models.CharField(max_length=200)type = models.CharField(max_length=3, default='cin')date = models.DateField()user = models.ForeignKey(User)image = models.ImageField(upload_to='images/',default='images/default.png')

And i have a view to output events on a page:

def home(request):all_events = Event.objects.all.order_by('date')return render(request, 'events/home.html', {'events': all_events})

in template -

{% block content %}<h1>{{ Event.name }}</h1><pre>{{ Event.date }}</pre><pre>{{ Event.description }}</pre>
{% endblock %}

I tried to use ManyToManyField like this but i dont understand exactly how it should work - what code should be in views.py, models.py and in template (button). Please help me

First step. I think, the relation should be ManyToMany . Event can be followed by multiple Users, and a User follow multiple Events.

model.py

class Event(models.Model):...users = models.ManyToManyField(User, blank=True)...

views.py user follow an Event

def follow(request,event_id):user = request.userevent = Event.objects.get(id=event_id)event.users.add(user)event.save()

urls.py

...
url(r'^event/(?P<event_id>\d+)/follow$', views.follow, name="event_follow"),
...

template.html

<a href="{% url 'event_follow' event.id %}">Follow</a>

or

<a href="/event/event_id/follow">Follow</a>
