Mapping a foreign key value in a Django template

Here is my problem. I am new to python / django (about 2 months). I have 2 tables, project and status. I have a foreign key pointing from status to project, and I'm trying to show the value of the foreign key (status) in the project template instead of the foreign key address.

Here are my models.py

from django.db import models
from clients.models import Clients
from django.contrib.auth.models import User
from settings import STATUS_CHOICES

from django.db import models
from clients.models import Clients
from django.contrib.auth.models import User
from settings import STATUS_CHOICES

class Project(models.Model):
   client = models.ForeignKey(Clients, related_name='projects')
   created_by = models.ForeignKey(User, related_name='created_by')


#general information
   proj_name = models.CharField(max_length=255, verbose_name='Project Name')
   pre_quote = models.CharField(max_length=3,default='10-')
   quote = models.IntegerField(max_length=10, verbose_name='Quote #', unique=True)
   desc = models.TextField(verbose_name='Description')
   starts_on = models.DateField(verbose_name='Start Date')
   completed_on = models.DateField(verbose_name='Finished On')

   def __unicode__(self):
      return u'%s' % (self.proj_name)   


class Status(models.Model):
  project = models.ForeignKey(Project, related_name='status')
  value = models.CharField(max_length=20, choices=STATUS_CHOICES,                     verbose_name='Status')
  date_created= models.DateTimeField(auto_now=True) 

  def __unicode__(self):
     return self.value

  class Meta:
      verbose_name = ('Status')
      verbose_name_plural = ("Status")

My views.py

@login_required
 def addProject(request):
 if request.method == 'POST':
      form = AddSingleProjectForm(request.POST)
      if form.is_valid():
        project = form.save(commit=False)
        project.created_by = request.user  
        project.save()
        project.status.create(
                value = form.cleaned_data.get('status', None)
        )            
        return HttpResponseRedirect('/project/')
 else:
    form = AddSingleProjectForm()

 return render_to_response('project/addProject.html', {
 'form': form, 'user':request.user}, context_instance=RequestContext(request))

And finally, my template:

{% if project_list %}
<table id="plist">
    <tr id="plist">
        <th>Quote #</th>
        <th>Customer</th>
        <th>Date</th>
        <th>Project Name</th>
        <th>Status</th>
        <th>Contact</th>
    </tr id="plist">
    {% for p in project_list %}
    <tr id="plist">
        <td><a href="/project/{{ p.id }}/view">{{ p.pre_quote }}{{ p.quote }}</a></td>
        <td>{{ p.client }}</td>
        <td>{{ p.starts_on }}</td>
        <td>{{ p.proj_name }}</td>
        <td>{{ p.status_set.select_related }}</td>
    <td>{{ p.created_by }}</td>
    </tr>
     {% endfor %}
    </table>

{% else %}
    <p>No projects available.</p>
{% endif %}

Any help would be greatly appreciated. Thank!

I assume what you mean here:

<td>{{ p.status_set.select_related }}</td>

. select_related - , . , p.status_set.all.

ForeignKey "". , "" "_set".

ForeignKey (ManyToOne), , . .all, , . .

, , OneToOne ForeignKey.
