first of all thanks for your time.
i've just learned CreateView UpdateView and DeleteView models. and them i got all of them working. i can change my object i can delete them but after deleting an object i try to create another and creates one like the before hasn't been deleted. giving me the following pk of the deleted before

it still creates de object although the pk at the moment should be 3, i think after i click de delete button and confirm delete it isnt deleting from data.

Those are my models:

> from django.db import models from django.urls import reverse

> 

> 

> 

> class Dreams (models.Model):

>     titulo = models.CharField(max_length=100)

>     objetivo = models.CharField(max_length=100)

>     imagem = models.CharField(max_length=100)

> 

>     def get_absolute_url(self):

>         return reverse ('webdeve:index', kwargs={'pk': self.pk})

> 

>     def __str__(self):

>         return self.titulo + ' - ' + self.objetivo

> 

> 

> class Wich (models.Model):

>     lets = models.ForeignKey(Dreams, on_delete=models.CASCADE)

>     make = models.CharField(max_length=100)

>     it = models.CharField(max_length=100)

>     favorite = models.BooleanField(default=False)

> 

>     def __str__(self):

>         return self.make

my views.py:

from django.views import generic

from django.views.generic.edit import CreateView, UpdateView, DeleteView

from .models import Dreams, Wich

from django.urls import reverse_lazy





class IndexView (generic.ListView):

    template_name = 'index.html'



    def get_queryset(self):

        return Dreams.objects.all()



class DetailView (generic.DetailView):

    model = Dreams

    template_name = 'detail.html'



class DreamCreate (CreateView):

    model = Dreams

    fields = ['titulo', 'objetivo', 'imagem']

    template_name = 'dreams_form.html'





class DreamUpdate (UpdateView):

    model = Dreams

    fields = ['titulo', 'objetivo', 'imagem']

    template_name = 'dreams_form.html'



class DreamDelete (DeleteView):

    model = Dreams

    template_name= ('dreams_confirm_delete.html')

    success_url= reverse_lazy('webdeve:index')

my urls.py:

from django.conf.urls import url

from webdeve import views



app_name = 'webdeve'



# Dreams



urlpatterns = [

    url(r'^$', views.IndexView.as_view(), name='index'),



# Dreams/detail



    url(r'^(?P<pk>[0-9]+)/$', views.DetailView.as_view(), name='detail'),



# Dreams/detail/add

    url(r'^dream/add/$', views.DreamCreate.as_view(), name='dream-add'),



# Dreams/detail/Update



    url(r'^dream/(?P<pk>[0-9]+)/$', views.DreamUpdate.as_view(), name='dreams-uptdate'),

# Dreams/detail/detete



    url(r'^dream/(?P<pk>[0-9]+)/delete/$', views.DreamDelete.as_view(), name='dreams-delete'),



]

And my index.html with delete button:

<!-- linkando css no html -->

{% extends 'base.html' %}

{% block nav %}



      <ul>

        {% for Dreams in object_list %}

            <a href="{% url 'webdeve:detail' Dreams.id %}"><img src={{ Dreams.imagem }}></a>

            <li><a href="{% url 'webdeve:detail' Dreams.id %}"> {{ Dreams.titulo }} - {{ Dreams.objetivo }} </a><li>



            <!--delete BUTTON-->



              <form action="{% url 'webdeve:dreams-delete' Dreams.id %}">

                {% csrf_token %}

                <input type="hidden" name="dreams_id" value="{{ Dreams.id }}" method="post" style="display: inline" >

                <button type="submit" class="btn btn-default btn-sm">

                  <span class="glyphicon glyphicon-trash"></span>

                </button>

              </form>

        {% endfor %}

      </ul>

{% endblock %}

DeleteView only deletes your object on POST, not GET. As a result, you need to use method="post" in your form since GET would render this confirm_delete.html again.

<form method="post" action="">

...

</form>

If you can get into DeleteView on GET, action="" is all you need to POST.
