Django - how to perform delete object using a view

Question

This is my code in my html

{% for summary in psummary %}
<tr>
<td colspan="3" class="tdcell">{{summary.Description}}</td>
<td colspan="2" class="tdcell">{{summary.Start_Grading_Period}}</td>
<td colspan="2" class="tdcell">{{summary.End_Grading_Period}}</td>
<td colspan="2" class="tdcell">{{summary.Method}}</td>
<td colspan="3" class="tdcell"><span style="text-align: right;font-weight: 600;" class="close" onclick="deleteRow(this)"><a href="url:delete_view">&times;</a></span></td>
</tr>
{% endfor %}

this is how it looks like

this is my views.py

def function(request,part_id =None):
    object = gradingPeriodsSummary.objects.get(id=part_id)
    object.delete()

    print(object)
    return render(request, 'admin/Homepage/view.html')

urls.py

path('delete/(?P<part_id>[0-9]+)/$', Homepage.views.function, name='delete_view'),

i just want that if the teacher click the close button it will delete the record in the database

i followed the instruction here, but its not working Django - How to delete a object directly from a button in a table

You will get an error on print(object) as it's .... deleted. Beside that, your code looks correct, what's the matter? — Julien Kieffer

You are not passing the id to the URL. Try adding the id to your link:

<a href="{% url "delete_view" summary.id %}" >&times;</a>

You can try the above, change the url definition but still pass the id

Update your href attribute to the example in the code above.

wrong url definition href="url:delete_view" must be href="{% url "delete_view" summary.id %}", use this

<td colspan="3" class="tdcell"><span style="text-align: right;font-weight: 600;" class="close" onclick="deleteRow(this)"><a href="{% url "delete_view" summary.id %}">&times;</a></span></td>

instead of using

<td colspan="3" class="tdcell"><span style="text-align: right;font-weight: 600;" class="close" onclick="deleteRow(this)"><a href="url:delete_view">&times;</a></span></td>
