Django if statement in DetailView returns False - django

The main problem for me was: If a user is the owner of the prime then it should return True. But it always returns False.
My models.py:
from django.db import models
from django.contrib.auth.models import User
from django.core.urlresolvers import reverse
class Prime(models.Model):
prime_owner = models.ForeignKey(User, null=True)
prime_name = models.CharField(max_length=100)
prime_address = models.CharField(max_length=250)
My views.py:
class PrimeDetails(generic.DetailView):
template_name ='prime/primedetails.html'
model = Prime
def get_context_data(self, **kwargs):
context = super(PrimeDetails, self).get_context_data(**kwargs)
user = self.request.user
prime_owner = Prime.prime_owner
if user == prime_owner:
owner = True
else:
owner = False
context['owner'] = owner
return context
primedetails.html
{% extends 'prime/base.html' %}
{% block content %}
<div class="container">
<h1>{{ owner }}</h1>
<h1>{{object.prime_name }}</h1>
<h3>{{object.prime_address}}</h3>
</div>
{% endblock %}

Prime is a model, not the object.
Try change the Prime to self.get_object(), like this:
def get_context_data(self, **kwargs):
context = super(PrimeDetails, self).get_context_data(**kwargs)
user = self.request.user
prime_owner = self.get_object().prime_owner
if user == prime_owner:
owner = True
else:
owner = False
context['owner'] = owner
return context

Django form fields required and optional configuration

I am in a middle of a project. I have a model :-
class CustomersModels(models.Model):
def servChoices(servs):
lst = [x.serv_name for x in servs]
ch =()
for a in lst:
ch += (a,a),
return ch
customer_name = models.CharField(max_length=100)
comp_name = models.CharField(max_length=100)
ph_no = models.CharField(max_length=12)
webs_name = models.URLField(max_length=200)
service_insterested = models.OneToOneField(ServiceModel, on_delete = models.CASCADE)
def __str__(self):
return self.customer_name
I have a corresponding form for this model.
Now what i want is the fields customer_name, comp_name, webs_name
to be optional in one page. And required in another page.
Please guide me to establish the task in the most convenient manner
Deleted in 'def servChoices', service_insterested because I don't have access to them in the model. I also made it to return a string with the name of the class return 'CustomersModels', so that you can edit, delete records with empty values.
The field class 'customer_name', 'comp_name' ,'webs_name' are set to blank=True to make them optional.
In the NoForm, the required field is 'ph_no'. YesForm requires all fields to be filled in. For this, a validator (clean) is used, which will display a message on the page which field is not filled in (the form will not be sent until all fields are filled). You can read about clean here:
In the bboard views, replace with your folder where you have the templates (this is the string template_name = 'bboard/templ_yes.html').

Unable to connect model to user in django

So i have a model called folder, i want to show all the folder created by current user on HomeView, but somehow it's not working, what i think is that folders are not getting connected to user who created them.
models.py
from django.db import models
from django.contrib.auth.models import User
from django.db.models.deletion import CASCADE
from django.core.validators import MinValueValidator
from django.core.exceptions import PermissionDenied
# The Folders Model.
class Folder(models.Model):
name = models.CharField(max_length = 250)
parent = models.ForeignKey('self', on_delete = CASCADE, null = True, blank = True )
cr_date = models.DateTimeField(auto_now_add = True)
user = models.OneToOneField(to=User, on_delete=CASCADE, null=True, blank=True)
def __str__(self):
return "%s" % self.name
view.py
class HomeView(TemplateView):
template_name = "ahmed_drive/home.html"
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
user = self.request.user
home_folders = Folder.objects.filter(user=user).order_by('-cr_date')
home_files = Fileshare.objects.filter(uploaded_by=user).order_by('-id')
context['home_folders'] = home_folders
context['home_files'] = home_files
return context
#method_decorator(login_required, name="dispatch")
class FolderCreate(CreateView):
model = Folder
fields = ["name", "parent"]
def formvalid():
if form.is_valid():
form.save()
return redirect('home.html')
else :
return render(request,{'form': form})
home.html
{% extends 'base.html' %}
{% block content %}
{% for Folder in home_folders %}
<h1> {{Folder.name}} </h1>
{% endfor %}
{% endblock %}
when you create folder you don't connect user to it.
you need to do it before saving form
def form_valid(self, form):
folder = form.save(commit=False)
folder.user = request.user
folder.save()
return redirect('home.html')

Django 2.2.9 - unexpected results from timedelta()

Please forgive me if this has already been asked
I am following a course online, albeit 3 years old, so somethings have been updated since then
However datetime seems to be roughly the same from what I can see.
The problem arises when we use timedelta to filter all the sales in the last month
I have added some test sales over the weeks and when I tried to filter it down to the last 48 hours, nothing
with a bit of testing i went back 12 days (as of this question and a list of items sold back on the 20th February showed up but nothing sooner.
I went into the admin and updated one of them and refreshed the page. and it disappeared completely
Can anyone provide any insight as to what i am missing?
If you need more information please say:

In your filter by_date method you are using a filter on the day not the date. This won't help as it'll return the day of the month. So if the date was 2020-03-11 it would return 29 for now.day. If you change .day for .date() as well as updated__day__gte for updated__date__gte it should be okay
def by_date(self):
now = timezone.now() - datetime.timedelta(days=12)
return self.filter(updated__date__gte=now.date())
The following should work fine:
now = timezone.now().date() - datetime.timedelta(days=12)
return self.filter(updated__date__gte=now)

This is the url mapping for the view.

HTML template
This is the template I used.
{% block sidebar %}

{% else %}
<p>Login to vote for this movie</p>
{% endif %} </div> {% endblock %}
Your UpdateVote view is using VoteForm and the queryset on that view is from Vote model, so that the object field inside that view is the instance of Vote model, not Movie model.
This code movie_id = context['object'].id also not work because context might not included object of UpdateVote view, that caused the error KeyError, Exception Value: 'object'. You could get movie_id via kwargs field inside UpdateVote view because you've already defined movie_id in the path.
With this:
path('movie/<int:movie_id>/vote/<int:pk>', UpdateVote.as_view(), name='UpdateVote'),
Your view can get the values by using kwargs like so:
class UpdateVote(LoginRequiredMixin,UpdateView):
form_class = VoteForm
queryset = Vote.objects.all()
def get_object(self,queryset=None):
vote = super().get_object(queryset)
user = self.request.user
if vote.user != user:
raise PermissionDenied('can not change another user vote')
return vote
def get_success_url(self):
movie_id = self.kwargs.get('movie_id')
return reverse('core:movie_detail', kwargs={'pk':movie_id})
def render_to_response(self, context, **response_kwargs):
movie_id = self.kwargs.get('movie_id')
movie_detail_url = reverse('core:movie_detail',kwargs={'pk':movie_id})
return redirect(to=movie_detail_url)

It is not displaying specific user value means it is displaying me everything.
can anyone tell me how to show specific user values/data?
You need to update your model so that it contains a field to store the user -
from django.contrib.auth.models import User
class IgaiaContent(models.Model):
#...
user = models.ForeignKey(User)
Then you need to create a ModelForm as described here.
class IgaiaContentForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
self.request = kwargs.pop('request', None)
return super(MyModelForm, self).__init__(*args, **kwargs)
def save(self, *args, **kwargs):
kwargs['commit']=False
obj = super(MyModelForm, self).save(*args, **kwargs)
if self.request:
obj.user = self.request.user
obj.save()
class Meta:
model = IgaiaContent
Now update your view so that that you use your new ModelForm
def create_page(request):
if request.method == 'POST':
form = IgaiaContentForm(request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect('/thanks/')
else:
