Я только начинаю работать с django и не понимаю, что делаю не так.
Вот мой models.py
class Task(models.Model):
project = models.ForeignKey(Project, null=True, on_delete=models.CASCADE)
title = models.CharField(max_length=300, null=True)
complete = models.BooleanField(default=False)
deadline = models.DateField('Deadline of the task (year, month, day)', default=date.today)
created = models.DateTimeField(auto_now_add=True,null=True)
lookup_id = models.UUIDField(default=uuid.uuid4, editable=False, db_index=True)
order = models.IntegerField(blank=False, default=100_000)
def __str__(self):
return self.title
def deadline_func(self):
days = self.deadline - date.today()
return days
Вот мой urls.py
from django.urls import path
from . import views
urlpatterns = [
path('' , views.projects_list, name="list"),
path('create_project/' , views.createProject, name="create_project"),
path('deadline_project/' , views.deadlineProject, name="deadline_project"),
path('update_project/' , views.updateProject, name="update_project"),
path('delete_project/' , views.deleteProject, name="delete_project"),
path('create_task/' , views.createTask, name="create_task"),
path('save-group-ordering/', views.save_new_ordering, name='save-group-oldering'),
path('deadline_task/' , views.deadlineTask, name="deadline_task"),
path('update_task/' , views.updateTask, name="update_task"),
path('delete_task/' , views.deleteTask, name="delete_task"),
]
Вот мои представления.py
@require_POST
def save_new_ordering(request):
form = OrderingForm(request.POST)
if form.is_valid():
ordered_ids = form.cleaned_data["ordering"].split(',')
with transaction.atomic():
current_order = 1
for lookup_id in ordered_ids:
group = Task.objects.get(lookup_id__exact=lookup_id)
group.order = current_order
group.save()
current_order += 1
return redirect('/')
Вот мой файл form.py
class TaskForm(forms.ModelForm):
class Meta:
model = Task
fields = '__all__'
class OrderingForm(forms.Form):
ordering = forms.CharField()
Вот мой HTML
{% for task in project.task_set.all %}
{% if task.complete == True %}
{% else %}
{% endif %}
{{task.title}}
{% endfor%}
{% csrf_token %}
Save ordering
