def updateItem(request):

request.data is available in Django rest framework, but it doesn't exist in regular Django views.
Change the view to use request.body instead.
def updateItem(request):
data = json.loads(request.body)

i have two similar tests:
def test_group_posts_context(self):
response = self.author_client.get(
reverse('posts:group_posts', kwargs={'slug': self.group.slug})
)
self.assertEqual(response.context.get('group'), self.group)
def test_author_profile_context(self):
response = self.author_client.get(
reverse('posts:profile', kwargs={'username': self.user.username})
)
self.assertEqual(response.context.get('author'), self.user)
Both tests work fine but I am trying to merge them in one single subTest.
But construction, like this raises a ValueError: too many values to unpack (expected 2).
def test_both_profile_and_group_show_correct_context(self):
templates_page_names = {
reverse('posts:index'),
reverse('posts:group_posts', kwargs={'slug': self.group.slug}),
reverse('posts:profile', kwargs={'username': self.post.author}),
}
for reverse_name in templates_page_names:
with self.subTest(reverse_name=reverse_name):
response = self.author_client.get(reverse_name)
context_fields = {
'group': self.group,
'author': self.user,
}
for value, expected in context_fields:
with self.subTest(value=value):
context_field = response.context.get(value)
self.assertEqual(context_field, expected)
My reviewer says, that I should try to use a Tuple like (page_address, context name, expected object), but I actually cant figure out how to use it here :(.
Views.py:
def group_posts(request, slug):
group = get_object_or_404(Group, slug=slug)
page_obj = get_paginate(
request.GET.get('page'),
group.posts.select_related('author')
)
context = {
'group': group,
'page_obj': page_obj,
}
return render(request, 'posts/group_list.html', context)
def profile(request, username):
author = get_object_or_404(User, username=username)
page_obj = get_paginate(
request.GET.get('page'),
author.posts.select_related('group')
)
context = {
'author': author,
'page_obj': page_obj,
}
return render(request, 'posts/profile.html', context)
I'm working on a Django project where I want to use ajax jquery to complete my search in my search form.
Tried everything, but it does not seem to work.
Pls, where have I missed it?
used this tutorial
views.py
import json
def search(request):
if request.method == 'POST':
form = SearchForm(request.POST)
if form.is_valid():
query = form.cleaned_data['query']
catid = form.cleaned_data['catid']
if catid == 0:
products = Product.objects.filter(name__icontains=query)
else:
products = Product.objects.filter(name__icontains=query, category_id=catid)
category = Category.objects.all()
context = {
'products': products,
'category': category,
'query': query,
}
return render(request, 'shop/product/search.html', context)
return HttpResponseRedirect('/')
def search_auto(request):
if request.is_ajax():
q = request.GET.get('term', '')
products = Product.objects.filter(name__icontains=q)
results = []
for pl in products:
product_json = {}
product_json = pl.name
results.append(product_json)
data = json.dumps(results)
else:
data = 'fail'
mimetype = 'application/json'
return HttpResponse(data, mimetype)
<script>
$(function() {$("#query").autocomplete({
url: "{% url 'shop:search_auto' %}",
select: function (event, ui) {AutoCompleteSelectHandler(event, ui)},
minLength: 2,
});
});
function AutoCompleteSelectHandler(event, ui)
{var selectedObj = ui.item;}
</script>
path('search', views.search_auto, name='search_auto'),
Thanks.
Im new in Django,
I'm using xhtml2pdf for rendering data objects from template to PDF file , and i want to allow users to render only checked objects by checkboxes into pdf, is there anyway to filter that in Django ?
Thanks
views.py :
def render_to_pdf(template_src, context_dict={}):
template = get_template(template_src)
html = template.render(context_dict)
result = BytesIO()
pdf = pisa.pisaDocument(BytesIO(html.encode('ISO-8859-1')), result, link_callback=link_callback)
if pdf.err:
return HttpResponse('Error')
return HttpResponse(result.getvalue(), content_type='application/pdf')
class ViewPDF(View):
#method_decorator(login_required(login_url='livraison:login_page'))
def get(self, request, *args, **kwargs):
checked_objects = [i dont know how to get them]
queryset = Livraison.objects.filter(id__in=[checked_objects]) # i want something does that
data = {
'livraisons' : queryset,
'now' : f'Livraisons-{date.today()}'
}
pdf = render_to_pdf('pdf_template.html', data)
return HttpResponse(pdf, content_type='application/pdf')
use forms to get user data.
class LivraisonSelectForm(forms.Form):
livraison = forms.ModelChoiceField(label='select', queryset=Livraison.objects.all(), widget=forms.CheckboxInput())
then use it in your view:
class ViewPDF(FormView):
form_class = LivraisonSelectForm
template_name = 'path_to_template_with_html_to_filter_data'
#method_decorator(login_required(login_url='livraison:login_page'))
def form_valid(self, form):
checked_objects = form.cleaned_data.get('livraison', [])
queryset = Livraison.objects.filter(id__in=checked_objects) # i want something does that
data = {
'livraisons' : queryset,
'now' : f'Livraisons-{date.today()}'
}
pdf = render_to_pdf('pdf_template.html', data)
return HttpResponse(pdf, content_type='application/pdf')
and don't forget to show this form in your html {{ form }}
**
UPDATE
**
I Found a solution , i used Ajax code to collect every selected object
// check selected objects (#pdf is the id of the button which gonna generate the pdf file)
$('#pdf').click(function () {
var id = [];
$(':checkbox:checked').each(function (i) {
id[i] = $(this).val()
})
if (id.length === 0) {
alert('Please Select something..');
} else {
$.ajax({
url: '.',
method: 'GET',
data: {
id,
},
success: function (response) {
console.log('PDF is ready')
}
})
}
});
then i ad the variable into the view function to collect the selected objects and filter the queryset
myFunction.selected_ones = request.GET.getlist('id[]')
then filter queryset in the generated_pdf_func
queryset = MODEL.objects.filter(id__in=[x for x in myFunction.selected_ones if x != '0'])
NOTE : <if x != '0'> is important in case you want to select all because it returns 0 and you don't have any id = 0 in the DB
Can anyone please help me to fix this problem local variable 'intent' referenced before assignment i could not find out why client_secret in the context is triggered. to my knowledge if the code in if statement fails then else block will be executed but i have set a print statement and it does not appear in the teminal either. if someone can please help me in solving this issue.

If your method == "POST": is true then the intent variable is not assigned any parameter.

Hence, the intent in last section is not assigned anything.

---> intent = stripe.PaymentIntent.create(

intent is assigned inside the else block, but it is referenced outside the else block
context = {
'order_form': order_form,
'stripe_public_key': stripe_public_key,
---> 'client_secret': intent.client_secret,
So if the else block is not executed there is no intent variable.
Thanks every one for your valuable input I found the problem and fixed it. Actually I was not returning anything if the form is valid! Thus I was missing the redirect to checkout_success page at the first for loop level before 1st else.
That is why even if the form is valid it's still trying to return the render() statement at the bottom which was causing this error. Thus I created a checkout_success view and and also checkout_success.html and redirected to it. like this and fixed this error.
return redirect(reverse('checkout_success',
args=[order.order_number]))
I'm using Stripe for my django site to accept one-off payments. The following code works fine and the charge is successfull:
def pay(request):
# Set your secret key: remember to change this to your live secret key in production
# See your keys here: https://dashboard.stripe.com/account/apikeys
stripe.api_key = "sk_test_exhH8mdKfkXkaxzvtVphJOBZ"
# Token is created using Checkout or Elements!
# Get the payment token ID submitted by the form:
if request.POST.get('stripeToken'):
print(request.POST)
token = request.POST.get('stripeToken')
charge = stripe.Charge.create(
amount=999,
currency='usd',
description='Boosted Post',
source=token,
)
print('Charge:', charge)
return HttpResponseRedirect('/')
else:
print('NO')
context = {
'amount': 999,
}
return render(request, 'advertising/pay.html', context)
however if I add context to this view, it doesn't work (if request.POST.get('stripeToken') doesn't fire):
def post_ad(request):
boost_form = AdvertisePostForm(request.POST or None, request.FILES or None)
if boost_form.is_valid():
instance = boost_form.save(commit=False)
instance.total_price = ad_price(instance.position, instance.duration)
instance.ad = True
instance.save()
context = {
'hash': instance.hash,
}
return pay(request, context)
else:
pass
context = {
'boost_form': boost_form
}
return render(request, 'advertising/post_ad.html', context)
def pay(request, context):
ad = get_object_or_404(AdvertisePost, hash=context['hash'])
amount = ad.total_price * 100
# Set your secret key: remember to change this to your live secret key in production
# See your keys here: https://dashboard.stripe.com/account/apikeys
stripe.api_key = "sk_test_exhH8mdKfkXkaxzvtVphJOBZ"
# Token is created using Checkout or Elements!
# Get the payment token ID submitted by the form:
if request.POST.get('stripeToken'):
print(request.POST)
token = request.POST.get('stripeToken')
charge = stripe.Charge.create(
amount=amount,
currency='usd',
description='Boosted Post',
source=token,
)
print('Charge:', charge)
return HttpResponseRedirect('/')
else:
print(request.POST)
print('NO')
context = {
'amount': amount,
'ad': ad
}
return render(request, 'advertising/pay.html', context)
Any idea why this is and how I can fix it?
