I am new in programming and trying to make a website for Todo by using Python-django. I am using Django Class Based Update View to make edit in datas. But while I am click on submit button its not get saved.

models.py

class Task(models.Model):
name=models.CharField(max_length=25)
details=models.CharField(max_length=750)
priority=models.CharField(max_length=500)
date=models.DateField()
user=models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)

def __str__(self):
    return self.name

views.py

class TaskUpdateView(UpdateView):
model = Task
fields = "__all__"
template_name = 'update.html'
context_object_name = 'task'
success_url = reverse_lazy('cbvhome')

urls.py

path('update/<pk>',views.TaskUpdateView.as_view(),name='cbvupdate')

update.html

<form method="post"  enctype="multipart/form-data">
                    {% csrf_token %}
                    <div >
                      <label for="task-id" >Task</label>

CodePudding user response：

By default if nothing is given in url params, so it is considered as str type, so define it as int:

path('update/<int:pk>/',views.TaskUpdateView.as_view(),name='cbvupdate')

It will be better if you give action="{% url 'cbvupdate' %}" in form tag of HTML although not necessary as Django always takes current page route.

Note: Always add / at the end of every route.
