Show values in dropdown list in Django - django

Question

I want to add documents about different parts of my facility in my Django app.
So, I have the following models in my models.py:
class Parts(models.Model):
Name = models.CharField(max_length=50)
class Docs(models.Model):
Date = models.DateField(default=date.today)
Type = models.CharField(max_length=50)
Part = models.ForeignKey(Parts)
Link = models.FileField(upload_to='Docs/%Y/%m/%d')
forms.py:
class DocsForm(ModelForm):
class Meta:
model = Docs
fields = ['Date', 'Type', 'Part', 'Link']
class PartsForm(ModelForm):
class Meta:
model = Parts
fields = ['Name']
views.py:
def adddocs(request):
if request.method == 'POST':
f = DocsForm(request.POST, request.FILES)
if f.is_valid():
f.save()
return HttpResponseRedirect('')
else:
form = DocsForm()
return render(
request,
'adddocs.html',
{'form': form}
and the following fragment in my template:
<form action="{% url 'adddocs' %}" method="post" enctype="multipart/form-data">
{% csrf_token %}
<p> {{form.Date}} </p>
<p> {{form.Type}} </p>
<p> {{form.Part}} </p>
<p> {{form.Link}} </p>
<p><input type="submit" value="Add" /></p>
</form>
And everything works fine except one problem. Now I have two parts of my facility, for example 'tubes' and 'storage'. But if I want to choose them in dropdown list, I see the following variants in my browser:
Parts Object
Parts Object
What should I change to see names of parts like this
tubes
storage
?

You need the str() method in your Models.
The str() method is called whenever you call str() on an object. Django uses str(obj) in a number of places. Most notably, to display an object in the Django admin site and as the value inserted into a template when it displays an object. Thus, you should always return a nice, human-readable representation of the model from the str() method.
class Parts(models.Model):
Name = models.CharField(max_length=50)
# call to return name
def __str__(self):
return self.Name
