Im trying to add a payment method.
I also add Getway and Get Success Message.
Now I want to show success message with cid and name in my template page.
When I want to get context data, I got This Error.
** Local variable 'cid' referenced before assignment. **
My code:
class CheckoutSuccessView(View):
model = Transaction
template_name = 'success.html'
def get(self, request, *args, **kwargs):
# return render(request, self.template_name,{'transaction':transaction})
return HttpResponse('nothing to see')
def post(self, request, *args, **kwargs):
data = self.request.POST
try:
Transaction.objects.create(
name = data['value_a'],
cid = data['value_b'],
tran_id=data['tran_id'],
val_id=data['val_id'],
amount=data['amount'],
card_type=data['card_type'],
card_no=data['card_no'],
...
...
)
messages.success(request,'Payment Successfull')
name = data['value_a'],
cid = data['value_b'],
except:
messages.success(request,'Something Went Wrong')
context = {
'cid': cid,
'name' : name
}
return render(request, 'success.html', context)
You may miss block or put extra indentation.
Define it before try block.
You may try this:
class CheckoutSuccessView(View):
model = Transaction
template_name = 'success.html'
def get(self, request, *args, **kwargs):
# return render(request, self.template_name,{'transaction':transaction})
return HttpResponse('nothing to see')
def post(self, request, *args, **kwargs):
data = self.request.POST
name = data['value_a'],
cid = data['value_b'],
try:
Transaction.objects.create(
name = data['value_a'],
cid = data['value_b'],
tran_id=data['tran_id'],
val_id=data['val_id'],
amount=data['amount'],
card_type=data['card_type'],
card_no=data['card_no'],
...
...
)
messages.success(request,'Payment Successfull')
except:
messages.success(request,'Something Went Wrong')
context = {
'cid': cid,
'name' : name
}
return render(request, 'success.html', context)
I think you are using sslcommerz-lib for SSLCOMMERZ PAYMENT GATEWAY.

I use a CB ListView for displaying objects. I want to add a session variable based on another models' PK during the execution of my ListView:
views.py
class ProduitListView(LoginRequiredMixin, ListView):
model = Produit
context_object_name = "produits"
paginate_by = 10
template_name = 'products/produits.html'
ordering = ['-mageid', ]
def get_context_data(self, *args, **kwargs):
context = super(ProduitListView, self).get_context_data(
*args, **kwargs)
# used for incoming products (sourcing cf URLS)
supplier_pk = self.kwargs.get('pk', None)
if supplier_pk:
set_incoming_supplier(self.request, supplier_pk)
context['avail_warehouses'] = Warehouse.objects.all()
context['js_warehouses'] = serialize(
'json', Warehouse.objects.all(), fields=('code', 'id', ))
context['title'] = 'Produits'
return context
set_incoming_supplier (in another APP)
#login_required
def set_incoming_supplier(request, pk):
supplier = Supplier.objects.filter(pk=pk).first()
supp = SupplierSerializer(instance=supplier).data
rs = request.session
if 'income' in rs:
if 'cur_supplier' in rs['income']:
prev_supplier = rs['income']['cur_supplier']
if supp != prev_supplier:
return render(request, 'sourcing/alert_supplier_change.html',
{'prev_supplier': prev_supplier, 'cur_supplier': rs['income']['cur_supplier']})
rs['income'] = {'cur_supplier': supp}
I thought the return render(request, 'sourcing/alert_supplier_change... could "break" my ListView and render my alert page but it doesn't. ListView seems to continue and finally renders my ProduitListView page.
Why doesn't this work ?
Finally found a solution that consists in using get() method within my CBV. In it, I evaluate my supplier with set_incoming_supplier() that returns a context or None. According to this evaluation, I render either the regular template or my alert template.
ProduitListView(LoginRequiredMixin, ListView):
class ProduitListView(LoginRequiredMixin, ListView):
model = Produit
context_object_name = "produits"
paginate_by = 10
template_name = 'products/produits.html'
ordering = ['-mageid', ]
def get_context_data(self, *args, **kwargs):
context = super(ProduitListView, self).get_context_data(
*args, **kwargs)
context['avail_warehouses'] = Warehouse.objects.all()
context['js_warehouses'] = serialize(
'json', Warehouse.objects.all(), fields=('code', 'id', ))
context['title'] = 'Produits'
return context
def get(self, request, *args, **kwargs):
supplier_pk = self.kwargs.get('pk', None)
if supplier_pk:
context = set_incoming_supplier(self.request, supplier_pk)
if context:
return render(request, 'sourcing/alert_supplier_change.html', context)
return super().get(request, *args, **kwargs)
set_incoming_supplier()
def set_incoming_supplier(request, pk):
supplier = Supplier.objects.filter(pk=pk).first()
supp = SupplierSerializer(instance=supplier).data
rs = request.session
if 'income' in rs:
if 'cur_supplier' in rs['income']:
prev_supplier = rs['income']['cur_supplier']
if supp != prev_supplier:
return {'prev_supplier': prev_supplier, 'cur_supplier': supp}
rs['income'] = {'cur_supplier': supp}
Maybe not the best way but it works well.
i want that a form is prepoluate with data
my model:
TYPE = (("S",'Swing'),
("R","Rapide"))
class valuation(models.Model):
stock = models.ForeignKey("stock",on_delete=models.CASCADE,related_name='valuation',)
date = models.DateField(auto_created=True)
val_type = models.CharField(choices=TYPE, max_length=1,default='R')
user = models.ForeignKey("users.User", on_delete=models.CASCADE)
def __str__(self):
return f"{self.stock} - {self.date} - {self.val_type}"
my view:
class valuationCreateviewSwing(CreateView):
template_name = "evaluation/evaluation_create.html"
form_class = valuationModeform
def get_form_kwargs(self): # prepopulate form
kwargs = super(valuationCreateviewSwing, self).get_form_kwargs()
stck = get_object_or_404(stock, pk=self.kwargs['pk'])
kwargs['user'] = self.request.user
kwargs['val_type'] = "S"
kwargs['stock'] = stck
return kwargs
def get_context_data(self, **kwargs):
# we need to overwrite get_context_data
# to make sure that our formset is rendered
data = super().get_context_data(**kwargs)
if self.request.POST:
data["val_detail"] = ChildFormset1(self.request.POST)
else:
data["val_detail"] = ChildFormset1()
data.update({
"typeVal": "Swing",})
return data
def form_valid(self, form):
context = self.get_context_data()
val_detail_Swing = context["val_detail_Swing"]
self.object = form.save(commit=False)
# add data info neede about valuation model
self.object = form.save()
if val_detail_Swing.is_valid():
val_detail_Swing.instance = self.object
val_detail_Swing.save()
return super().form_valid(form)
def get_success_url(self):
return reverse("stock:stock-list")
I've a child form in my view (this part works ok):
ChildFormset1 = inlineformset_factory(
valuation, val_detail_Swing, form=valuationSwingModelform, can_delete=False)
I tried to use ge_for_kwargs but it seems not working as I've an error message :
init() got an unexpected keyword argument 'user'
You can use get_initial() method:
class valuationCreateviewSwing(CreateView):
template_name = "evaluation/evaluation_create.html"
form_class = valuationModeform
def get_initial(self):
query = self.request.GET
return {
'user': self.request.user.pk
'val_type': "S",
'stock': self.kwargs.get('pk')
}
...
Or you should override __init__() method and stay to use get_form_kwargs()
class valuationModeform(ModelForm):
class Meta:
model = Valuation
fields = '__all__'
def __init__(self, *args, **kwargs):
user = kwargs.pop('user', None)
val_type = kwargs('val_type', None)
stock = kwargs.pop('stock', None)
super().__init__(*args, **kwargs)
# assign initial values
self.fields['user'].initial = user
self.fields['val_type'].initial = val_type
self.fields['stock'].initial = stock
Here all My codes and I haven't set it yet, just a regular auth
class login(View):
template_name = "admin/page.html"
context = {}
def get(self, *args, **kwargs):
next = self.request.GET.get('next')
forms = adminForm()
if next :
self.context['next'] = next
self.context['forms'] = forms
return render(self.request, self.template_name, self.context)
def post(self, *args, **kwargs):
forms = adminForm(self.request.POST or None)
next = self.request.POST.get('next')
if forms.is_valid() :
user = authenticate(username=forms.cleaned_data.get('username'), password=forms.cleaned_data.get('password'))
login(self.request, user)# authenticate(username=forms.cleaned_data.get('username'), password=forms.cleaned_data.get('password')))
if next :
return redirect(next)
return redirect('/admin/users')
if not forms.is_valid() :
self.context['errors'] = 'Invalid Username or Password'
self.context['forms'] = forms
return render(request, self.template_name, self.context)
I am wondering how to run a reality check to decide which template file to use. How do I access agency_count from AgencyFullView? What I currently have returns type object 'AgencyFullMixin' has no attribute 'agency_count'
class AgencyFullMixin(ContextMixin):
def get_context_data(self, pk, **kwargs):
context_data = super(AgencyFullMixin, self).get_context_data(**kwargs)
agency = Agencies.objects.filter(pk=pk)
context_data["agency"] = agency
agency_count = agency.count()
context_data["agency_count"] = agency_count
return context_data
class AgencyFullView(TemplateView, AgencyFullMixin):
if agency_count != 0: **<<<--- What to put here?**
template_name = 'community_information_database/agency_full.html'
else:
template_name = 'community_information_database/not_valid.html'
def get_context_data(self, **kwargs):
context_data = super(AgencyFullView, self).get_context_data(**kwargs)
return context_data
If you want to access agency_count in another method, then you'll have to set it as an attribute. You could do this in the dispatch method.
class AgencyFullMixin(ContextMixin):
def dispatch(self, request, *args, **kwargs):
agencies = Agencies.objects.filter(pk=self.kwargs['pk'])
self.agency_count = agencies.count()
return super(AgencyFullMixin, self).dispatch(request, *args, **kwargs)
def get_context_data(self, **kwargs):
"""
Add the agency count to the context
"""
context = super(AgencyFullMixin, self).get_context_data(**kwargs)
context['agency_count'] = self.agency_count
return context
You can then access self.agency_count in other methods. To change the template name dynamically, you should override get_template_names.
class AgencyFullView(AgencyFullMixin, TemplateView):
def get_template_names(self):
if self.agency_count != 0:
template = 'community_information_database/agency_full.html'
else:
template = 'community_information_database/not_valid.html'
return [template] # nb get_template_names must return a list
Fixed: Here's the solution I am using:
class AgencyFullMixin(ContextMixin):
def get_context_data(self, pk, **kwargs):
context_data = super(AgencyFullMixin, self).get_context_data(**kwargs)
agency = Agencies.objects.filter(pk=pk)
context_data["agency"] = agency
agency_count = agency.count()
context_data["agency_count"] = agency_count
return context_data
class AgencyFullView(TemplateView, AgencyFullMixin):
def get_template_names(self, **kwargs):
agency = Agencies.objects.filter(pk=self.kwargs['pk']).filter(pk__isnull=False)
if agency:
return 'community_information_database/agency_full.html'
else:
return 'community_information_database/not_valid.html'
def get_context_data(self, **kwargs):
context_data = super(AgencyFullView, self).get_context_data(**kwargs)
return context_data
I want to pass variable appuser to template and I don't understand how to do it.
I have tried to use kwargs.update but it still doesn't work.
I have a view:
class CausesView(AjaxFormView):
appuser = None
causes = []
cause_allocation_set = None
def prepare_request(self, request, *args, **kwargs):
self.causes = Cause.objects.filter(is_main_cause = True)
self.appuser = AppUser.get_login_user(request)
self.cause_allocation_set = set([r.cause_id for r in self.appuser.current_cause_save_point.cause_allocations_list])
def prepare_context(self, request, context, initial):
initial.update(
causes = self.cause_allocation_set,
appuser = self.appuser,
)
def prepare_form(self, request, form):
form._set_choices("causes", [(r.id, r.title) for r in self.causes])
def custom_context_data(self, request, **kwargs):
kwargs.update(
special_test = "dsf"
)
return kwargs
def process_form(self, request, form):
data = form.cleaned_data
try:
with transaction.atomic():
if self.cause_allocation_set != set(data.get('causes')):
self.appuser.save_causes(data.get('causes'))
except Exception as e:
message = "There was an error with saving the data: " + str(e.args)
return AjaxErrorResponse({'title':"Error", 'message':message})
return AjaxSuccessResponse('Causes Saved')
And I have a form:
class CauseForm(AjaxForm):
causes = forms.TypedMultipleChoiceField(label="Select Causes", choices = (), required = False, coerce = int,
widget = forms.CheckboxSelectMultiple())
def clean(self):
cleaned_data = super(CauseForm, self).clean()
causes = cleaned_data.get('causes')
validation_errors = []
if not causes is None and not len(causes):
validation_errors.append(forms.ValidationError("At least one Cause is required"))
if len(validation_errors):
raise forms.ValidationError(validation_errors)
return cleaned_data
How can I get variable appuser in temlpate?
For example:
{{ appuser.name }}
doesn't work.
