Filter data in related_name loop

[tango ward]

Hi guys, I've been scratching my head on this one. I want to know if it's possible to filter the data of models class with related_name in a foor loop? Basically, I want to show the members info associated to a Team.

models.py

class Team_Region(models.Model):
    name = models.CharField(max_length=50)


    # String representation
    def __str__(self):
        return self.name





class Team_Name(models.Model):
    team_name = models.CharField(max_length=150)
    logo = models.ImageField(upload_to='team_logos', blank=True)
    region_member = models.ForeignKey(Team_Region, related_name='region_mem')


    def __str__(self):
        return self.team_name + ' - ' + str(self.region_member)




class Team_Member(models.Model):
    member_name = models.CharField(max_length=150)
    position = models.CharField(max_length=50)
    member_of_team = models.ForeignKey(Team_Name, related_name='team_mem')


    def __str__(self):
        return self.member_name + ' - ' + str(self.member_of_team)

views.py

# Listview of Regions
class TeamRegionListView(ListView):
    context_object_name = 'region_name'
    model = Team_Region
    template_name = 'dota_teams/team_region_list.html'



# DetailView of Regions
class TeamRegionDetailView(DetailView):
    context_object_name = 'team_names'
    model = Team_Region
    template_name = 'dota_teams/team_region_detail.html'



# DetailView of Teams. Will show team members
class TeamDetailView(DetailView):
    context_object_name = 'team_members'
    model = Team_Region
    template_name = 'dota_teams/team_detail.html'

urls.py

    url(r'^$', views.TeamRegionListView.as_view(), name='region_list'),
    url(r'^(?P<pk>\d+)/$', views.TeamRegionDetailView.as_view(), name='region_detail'),
    url(r'^(?P<pk>\d+)/(\d+)/$', views.TeamDetailView.as_view(), name='team_detail'),

Problem is, in my team_detail.html, for me to access the members' info, I have these loops:

    <div class="row">
        {% for team in team_members.region_mem.all %}
            {% for member in team.team_mem.all %}
                <div class="col-xs-12 col-lg-3">
                    <div class="thumbnail">
                        <h4>{{ member.member_name }}</h4>

                        <div class="caption">
                            <h5>{{ member.position }}</h5>
                        </div>
                    </div>
                </div>
            {% endfor %}
        {% endfor %}
    </div>

All members info will appear if i click a team which is not the way I want it. I only want to show the members info associated to a team that I clicked. This happens because I hae the team.team_mem.all in my loop which basically shows all members data including those who are not part of the team. Is there a way to filter this? My apologies for the long email.

TIA,
