(sorry for my bad english)
I need to delete an object, but directly from a list of the objects that y have in my template.
I have a work orders, that have spare parts but i don't know how to create the deleteview for the spare parts using only a buton in the detailview of the work order. The idea is that the user make click in the Delete button.
This is the model of the Spare Parts
class OrderSparePart(models.Model):
# Relations
workorder = models.ForeignKey(
WorkOrder,
verbose_name=_('order'),
)
# Attributes - Mandatory
spare_part = models.CharField(
max_length=80,
verbose_name=_('spare part'),
)
# Attributes - Optional
price = models.DecimalField(
max_digits=6,
decimal_places=2,
null=True,
blank=True,
verbose_name=_('price'),
)
# Object Manager
# Custom Properties
# Methods
def get_absolute_url(self):
return reverse('work_orders:detail', kwargs={'order_id': self.workorder.id})
# Meta and String
class Meta:
verbose_name = _("order spare part")
verbose_name_plural = _("order spare parts")
This is where is showed in the template
{% if spare_parts %}
<table class="table">
<thead>
<tr>
<th>{% trans "Spare Part" %}</th>
<th>{% trans "Price" %}</th>
<th>{% trans "Delete" %}</th>
</tr>
</thead>
<tbody>
{% for part in spare_parts %}
<tr>
<td><i class="fa fa-gear"></i> {{ part.spare_part }}</td>
{% if part.price %}
<td>$ {{ part.price }}</td>
{% else %}
<td></td>
{% endif %}
<td><a href="#"><i class="fa fa-trash"></i></a></td>
</tr>
{% endfor %}
</tbody>
</table>
{% else %}
<p>NO HAY REPUESTOS ASENTADOS AÚN</p>
{% endif %}
The the idea is use the to delete the spare part.
how i have to make the deleteview and the link to this???
Thanks!
here in fa fa-thrash pass the id and the URL as I did it:-
{% if spare_parts %}
<table class="table">
<thead>
<tr>
<th>{% trans "Spare Part" %}</th>
<th>{% trans "Price" %}</th>
<th>{% trans "Delete" %}</th>
</tr>
</thead>
<tbody>
{% for part in spare_parts %}
<tr>
<td><i class="fa fa-gear"></i> {{ part.spare_part }}</td>
{% if part.price %}
<td>$ {{ part.price }}</td>
{% else %}
<td></td>
{% endif %}
<td><a href="url:delete_view" part.id><i class="fa fa-trash"></i></a></td>
</tr>
{% endfor %}
</tbody>
</table>
{% else %}
<p>NO HAY REPUESTOS ASENTADOS AÚN</p>
{% endif %}
ur url would be sonething like that:
url(r'^delete/(?P<part_id>[0-9]+)/$', view.function, name='delete_view'),
in ur view:
def function(request,part_id =None):
object = YourModel.objects.get(id=part_id)
object.delete()
return render(request,'ur template where you want to redirect')
In your html template inside for loop use the form tag inside <td>
to create delete button as below (css class will work if you are using bootstrap3):
<form action="{% url 'delete_view' pk=part.pk %}" method="POST">
{% csrf_token %}
<input class="btn btn-default btn-danger" type="submit" value="Delete"/>
</form>
add urlpattern in urls.py
url(r'^delete-entry/(?P<pk>\d+)/$', views.DeleteView.as_view(), name='delete_view'),
delete view will be like below in views.py
class DeleteView(SuccessMessageMixin, DeleteView):
model = OrderSparePart
success_url = '/'
success_message = "deleted..."
def delete(self, request, *args, **kwargs):
self.object = self.get_object()
name = self.object.name
request.session['name'] = name # name will be change according to your need
message = request.session['name'] + ' deleted successfully'
messages.success(self.request, message)
return super(DeleteView, self).delete(request, *args, **kwargs)
Note: import necessary imports shown in links or you need not to worry if you are using IDE such as pyCharm it will prompt you which import to make.
