I got an attribute error on my NarrateUpdate view. I want to edit/update a user submission from a form
Here's my views.py:
class NarrateUpdate(SuccessMessageMixin, UpdateView):
model = Narrate
fields = ['title', 'body']
template_name = 'narrate_update_form.html'
success_url = reverse_lazy('narrate-status')
success_message = "Narration successfully updated"
def get(self, request, *args, **kwargs):
footer = FooterLinks.objects.all()
context = self.get_context_data(**kwargs)
context['footer'] = footer
return self.render_to_response(context)
The urls.py
path('narration/<int:pk>/update/', NarrateUpdate.as_view(), name='edit-narration'),
And here's the models.py:
class Narrate(models.Model):
STATUS = (
('F', 'FOR REVIEW'),
('P', 'PASSED'),
)
title = models.CharField(max_length=255)
body = models.CharField(max_length=10000)
status = models.CharField(
max_length=25, choices=STATUS, default='for_review', blank=True)
def __str__(self):
return self.title
def get_absolute_url(self):
return "/narration/%i/" % self.title
class Meta:
verbose_name = "narration"
verbose_name_plural = "narrations"
What can I do to make this work?
Why are you overriding the get method? If you want to add footer better to do it in get_context_data() method:
class NarrateUpdate(SuccessMessageMixin, UpdateView):
model = Narrate
fields = ['title', 'body']
template_name = 'narrate_update_form.html'
success_url = reverse_lazy('narrate-status')
success_message = "Narration successfully updated"
def get_context_data(self, **kwargs):
context = super(NarrateUpdate, self).get_context_data(**kwargs)
context['footer'] = FooterLinks.objects.all()
return context

Hello asd you can add flags like this in your Profile Model like this
class Profile(models.Model):
user = models.ForeignKey(User,on_delete=models.PROTECT)
is_moderator = models.BooleanField(default=False)
is_editor = models.BooleanField(default=False)#you can add many more as you want
and you can validate user in template or in views like this
in views.py
def check_user(request):
moderator_profile = Profile(user_id=request.user.id,is_moderator=True)
editor_profile = Profile(user_id=request.user.id,is_editor=True)
if user_profile:
return redirect('url_for_moderator')
elif editor_profile:
return redirect('url_for_editor')
OR
you can pass data to the template and give certain functionality for certain user
like this
in your views.py
def get_post(request):
user_profile = Profile.objects.filter(user=request.user.id)
return render(request,"post.html",{"user_profile":user_profile})
and inside post.html
{% if user_profile.is_editor or user_profile.is_moderator %}
<button>Edit</button>
{% endif %}
if you don't like this way you can do it in better way check this post

order by not working on queryset no working at all and i dont know where is the mistake seems everything is okay !

I have a problem with the form in django. It uses the CheckboxSelectMultiple widget, but I need to set a list of possible choices only for posts created by the currently logged in user.
Any idea?
form:
class CycleForm(BSModalForm):
class Meta:
model = Cycle
fields = ['title', 'description', 'posts']
widgets = {
'posts': forms.CheckboxSelectMultiple(),
}
models
class Cycle(models.Model):
title = models.CharField(max_length=200, unique=True)
description = models.TextField(max_length=500, default="Brak opisu")
date_created = models.DateTimeField(default=timezone.now)
author = models.ForeignKey(User, on_delete=models.CASCADE)
posts = models.ManyToManyField(Post)
def __str__(self):
return self.title
class Post(models.Model):
title = models.CharField(max_length=50, unique=True)
content = MDTextField()
date_posted = models.DateTimeField(default=timezone.now)
author = models.ForeignKey(User, on_delete=models.CASCADE)
numbers_of_entries = models.IntegerField(default=0)
views
class CycleCreateView(BSModalCreateView, LoginRequiredMixin):
template_name = 'blog/cycle_form.html'
form_class = CycleForm
def form_valid(self, form, **kwargs):
form.instance.author = self.request.user
return super().form_valid(form)
def get_success_url(self):
reverse_user = self.request.user
return reverse('profile', kwargs={'username': reverse_user})
class CycleUpdateView(BSModalUpdateView):
model = Cycle
template_name = 'blog/cycle_update.html'
form_class = CycleForm
success_message = 'Success: Cycle was updated.'
def get_success_url(self):
reverse_user = self.request.user
return reverse('profile', kwargs={'username': reverse_user})
We can slightly alter the CycleForm form and add a user parameter. If that parameter is set, we filter the queryset of the posts field by only using Posts
class CycleForm(BSModalForm):
def __init__(self, *args, user=None, **kwargs):
super().__init__(*args, **kwargs)
if user is not None:
self.fields['posts'].queryset = Post.objects.filter(author=user)
class Meta:
model = Cycle
fields = ['title', 'description', 'posts']
widgets = {
'posts': forms.CheckboxSelectMultiple(),
}
Now we only need to pass the user to the form, we can override the get_form_kwargs method [Django-doc]:
class CycleCreateView(LoginRequiredMixin, BSModalCreateView):
template_name = 'blog/cycle_form.html'
form_class = CycleForm
def get_form_kwargs(self):
kwargs = super().get_form_kwargs()
kwargs.update(user=self.request.user)
return kwargs
def form_valid(self, form, **kwargs):
form.instance.author = self.request.user
return super().form_valid(form)
def get_success_url(self):
reverse_user = self.request.user
return reverse('profile', kwargs={'username': reverse_user})
You should do the same with the UpdateView. Note that your LoginRequiredMixin likely should be put first in the base classes.
I created an update screen for django. However, although it redirects to successURL, the data has not been updated. I don't know why.
I need your help.
I will post it if necessary.
#view
class RecordDetailEdit(UpdateView,LoginRequiredMixin):
template_name = 'records/detail_edit.html'
model = URC
form_class = RecordDetailEditForm
pk_url_kwarg = 'id'
success_url = reverse_lazy('person:home')
def get_object(self):
return get_object_or_404(User, pk=self.request.user.user_id)
def get_form_kwargs(self):
kwargs = super(RecordDetailEdit, self).get_form_kwargs()
# get users, note: you can access request using: self.request
kwargs['user'] = self.request.user
return kwargs
#form
class RecordDetailEditForm(forms.ModelForm):
class Meta:
model = URC
fields = ('UPRC','URN','UET','URT')
def __init__(self, *args, **kwargs):
user = kwargs.pop('user')
super(RecordDetailEditForm, self).__init__(*args, **kwargs)
self.fields['URN'].queryset = UPRM.objects.filter(user=user)
#model
class URC(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
UPRC = models.CharField(max_length=300)
URN = models.ForeignKey(UPRM, on_delete=models.CASCADE)
UET = models.DurationField(editable=True)
URT = models.DateTimeField(default=timezone.now,editable=True)
group = models.ForeignKey(group, on_delete=models.CASCADE, null=True)
def __str__(self):
return self.UPRC
#url
path('<id>/edit/', views.RecordDetailEdit.as_view(), name='record_detail_edit'),
I changed it to the following.
def get_object(self, queryset=None):
obj = URC.objects.get(id=self.kwargs['id'])
return obj
I am not good at English.
Please understand me.
I'm creating a blog in Django.
I am making it into class view, but I want to see a reple list and form in the post details view.
like this
enter image description here
POST detailview has already been implemented and I don't know how to add comments.
Should I be function view?
Give me some advice.

It's my first time writing, so I don't know how to Indent. Sorry
And if my code is not effective, tell me how to fix it.
thank you!
It might be easier to write the view from scratch as a function, but you can also override the existing post method to return additional data.
