I am trying to make a ToDoList for every user.
I am using class based views and the auth User model.
For Every User, there is a List model, consisting the List Name, and a Task
model which is a child to the List.
I am having problem when I am updating a Task under a List.
I have my models.py, urls.py, views.py and the templates as follows.
models.py:
from django.db import models
from django.contrib.auth import get_user_model
from django.utils.text import slugify
from django.urls import reverse
User = get_user_model()
# Create your models here.
class List(models.Model):
LIST_TYPES = [('daily','Daily'),
('weekly','Weekly'),
('monthly', 'Monthly'),
('lifelong', 'Life Long')]
list_type = models.CharField(max_length = 10, choices = LIST_TYPES)
user = models.ForeignKey(User, related_name = 'list', on_delete =
models.CASCADE)
title = models.CharField(max_length = 32)
slug = models.SlugField(allow_unicode = True, unique = True)
created_at = models.DateTimeField(auto_now_add = True)
def __str__(self):
return self.title
def save(self, *args, **kwargs):
self.slug = slugify(self.title)
super().save( *args, **kwargs)
class Meta():
ordering = ['title']
class Task(models.Model):
list = models.ForeignKey(List, related_name = 'tasks', on_delete =
models.CASCADE)
user = models.ForeignKey(User, related_name = 'tasks', on_delete =
models.CASCADE)
name = models.CharField(max_length = 64)
task_slug = models.SlugField(allow_unicode = True)
completed = models.BooleanField(default = False)
created_at = models.DateTimeField(auto_now_add = True)
complete_before = models.DateTimeField()
class Meta():
ordering = ['complete_before']
def __str__(self):
return self.name
def save(self,*args, **kwargs):
self.task_slug = slugify(self.name)
super().save(*args, **kwargs)
def get_absolute_url(self):
return reverse('listApp:detail', kwargs={'slug':self.slug})
urls.py:-
from django.urls import path
from . import views
app_name = 'listApp'
urlpatterns = [
path('', views.ListListView.as_view(), name = 'all'),
path('create', views.ListCreateView.as_view(), name = 'create'),
path('<slug:slug>', views.ListDetailView.as_view(), name = 'detail'),
path('<slug:slug>/createtask', views.TaskCreateView.as_view(), name =
'createtask'),
path('<slug:slug>/updatetask/<slug:task_slug>',
views.TaskUpdateView.as_view(), name = 'updatetask'),
path('update/<slug:slug>', views.ListUpdateView.as_view(),
name='update'),
path('delete/<slug:slug>', views.ListDeleteView.as_view(),
name='delete'),
]
