Model Does Not Insert Record; Instead Updates Multiple Records With Date

[octopusgrabbus]

My problem is I create a model object and then save it. The data I put
in the model, which is not added. Instead an update of all similar
part numbers with the date occurs. I know about the override that
forces an insert. Is that what I should do?

Here is a sample of the data:
part_num,"ept_type","inv_id","load_date"
VWP-1602-201,43,80556338,"2011-02-15"                                           
                                                        I'm

Here is the web template:

 {% extends "base.html" %}

{% block content %}
    <h2>Load Single Inventory Unit </h2>

    {% if errors %}
        {% for error in errors %}
            {{ error }}
        {% endfor %}
        <br></br>
    {% endif %}

    <form action="." method="post"> {% csrf_token %}
    Inventory Part Number:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
<input type="text" name="part_num" size="12">
    <br></br>
    Inventory Type: &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
    <input type="text" name="ept_type" size="2">
    <br></br>
    Inventory Serial Number (ID): <input type="text" name="inv_id"
size="8">
    <br></br>
    <input type="submit" value="Load Inventory Unit">
    </form>
    <a href="/">AMR Application Main Page</a>
{% endblock content %}

Here is the view subroutine to handle the request from the web page
(partial listing):

from amr.inventory_add.models import EptInv

from funcs import *

from util_lib import *
from util_class_lib import *

def load_inv(request):
    errors = []
    if request.method == 'POST':
        if not request.POST.get('part_num', ''):
            errors.append('Please enter a valid inventory part
number.')
        else:
            if not request.POST.get('ept_type', ''):
                errors.append('Please enter a valid inventory type.')
            else:
                    requested_serial_number =
request.POST.get('inv_id', '')

                    try:
                        temp_ept_id =
EptInv.objects.get(inv_id=requested_serial_number)
                        errors.append('Endpoint is present in
inventory.')

                    except ObjectDoesNotExist:
                        # element was not found - it is OK to add to
database.
                        gd = createGlobalData(getMySQLDateTime())
                        load_date = gd.getMySQLDate()
                        inv_obj = \
 
EptInv(part_num=request.POST.get('part_num'), \
 
ept_type=request.POST.get('ept_type'), \
 
inv_id=request.POST.get('inv_id'), \
                                       load_date=load_date)
                        inv_obj.save()

  Here is the model:

from django.db import models

class EptInv(models.Model):
    part_num = models.CharField(max_length=60, blank=True)
    ept_type = models.IntegerField(primary_key=True)
    inv_id = models.IntegerField(primary_key=True)
    load_date = models.DateField(null=True, blank=True)
    class Meta:
        db_table = u'ept_inv'
