html python same value in 2 many to many -

this rather simple yet strange question.

i have 2 manytomany relationships in table pointing same other table (i need can know participated in event , finished it)

in html have table, , want field know if there , finished event.

the backend sending data html this:

for e in ev.event.all():   people.append(e) return render_to_response('event/review.html', {'event': people},  context_instance=requestcontext(request)) 

in html i've tried this:

{% p in event %}   {% if p.asistant in p.finish %}     <td>finish</td>   {% else %}     <td>       <form action="{% url ..... 

but nothing happens.

what i'm doing wrong?

my models this:

class event(models.model):   name = models.charfield(max_length=100, blank=true, null=true)   date = models.datetimefield(blank=true, null=true)   asistant = models.manytomanyfield(user, related_name='asistant_to_event', blank=true, null=true)   finish = models.manytomanyfield(user, related_name='finished_the_event', blank=true, null=true)
