PipeDrive - how to avoid loops when using WebHooks?
I'm working with PipeDrive API and I've started to use their webhooks. The problem is that it cause loops. Simple example: There is a model Deal which has two methods - Deal.sync(), Deal.backsync() Deal.sync() sends updated or created Deal object to the PipeDrive Deal.backsync() fetches Deal object from the PipeDrive But the problem is that when I call sync, the Deal object is sent to the PipeDrive which invokes webhook so my server receives this webhook and automatically invokes Deal.backsync() etc. I have some ideas but maybe there is some elegant way I don't know. Ideally, for example sync would send some uuid which would be sent in webhook so I know it was caused by sync. Do you know how to make this work? -

CKeditor incorrect display in Django admin panel

Is it a bad idea to save POST information without using django Forms?
I am currently developing a student survey app. when the student clicks the submit button on the form, activate the view with the following code: for key, value in request.POST.items(): if key != 'csrfmiddlewaretoken': # I don't want to save the token info item = Item.objects.get(pk=key) # I get the question(item) I want to save if item == None: return render(request, "survey/error.html") Answer.objects.create(item= item, answer=value, user = request.user) Since all the fields in the form are obligatory, I use the required value attribute in html. This code works and stores the information in the DB. However, I am concerned that because it is very "manual", it may generate errors when it is in production. However I do not know how to use django forms, so I would like to avoid having to learn it, if it is not necessary. -

JavaScript/jQuery downloading PDF file returned from Django view
I have a celery task that creates PDF files on the click of a button. When the button is clicked, the javascript side will keep checking until the task is done, and when it is, it will download the file.

Django RelatedObjectDoesNotExist After Upgrade to 2.2

All other ForeignKey relations in the application work as expected except for this one. This is quite puzzling and all help is appreciated. Thanks! -

Python requests inside a view hags out and needs timeout
I'm seeking help for this rather strange behaviour. I have a view that gets called after a button click @require_http_methods(['GET', 'POST']) @login_required @transaction.atomic def create_key(request, slug): #some unrelated code try: r = requests.post( some_url, data={ #some_data }, auth=(client_id, client_secret), timeout=(req_to, res_to) ) if r.status_code == 200: return True else: return False except ReadTimeout as to: # handle exception return True except Exception as e: # handle exception return False #some unrelated code that basically calls an API endpoint to create a key. Now the request with Postman works fine, taking out that python snippet and running it alone also works, but when put inside this Django view it hangs until reaches response timeout. Does anybody has any idea or pointer on where the problem might be? Thank you in advance! -

Django error "Reverse for 'x' not found. 'x' is not a valid view function or pattern name.", but x is a pattern name

How do I pass query parameters to the django rest api javascript client

And in that model i want the some fields from Cur_Payroll as default value like employee number,payperiod. What good way to approach this problem? class OvertimeCreate(LoginRequiredMixin,CreateView): model = Cur_OT template_name = 'payroll/transaction/otcreate.html' fields = [ 'empno', 'dtpay', 'cd_ot', 'ot_hrs', 'ot_amt', 'ty_ot', ] def get_context_data(self,**kwargs): from Home.models import hrm,t_pay context = super(OvertimeCreate,self).get_context_data(**kwargs) context['m_tpay'] = t_pay.objects.get(pk=self.kwargs['pk']) return context def post(self, request, *args, **kwargs): # What to put here? return super().post(request, *args, **kwargs) I tried to: <form method="post" href="{% url 'payrollTransactionUpdate' m_tpay.id %}"> in the createview for overtime. It redirects back to update but behavior is weird, updating doesnt work again. Tried this on Cur_OT model: def get_absolute_url(self): return reverse('payrollTransactionUpdate', kwargs={'pk': self.pk}) but this is not helpful since Cur_OT may have different pk than my Cur_Payroll Im thinking create a new form.Forms and do Formview instead, modify post method, import Cur_OT and Cur_Payroll … -
Dynamically add ProhibitNullCharactersValidator into the form's __init__ in Django. Need an advice
Quite a simple question for someone who knows the answer. Is it possible to dynamically add validator to a form’s field in froms init ??? I want to do something like this: class SomeForm(forms.ModelForm): def __init__(self, *args, **kwargs): self.pk = kwargs.pop("pk", None) forms.ModelForm.__init__(self, *args, **kwargs) if self.pk == some integer: self.fields[field].validator(s)…….. # and I don’t know what to type here else: do something else… Goal is to add ProhibitNullCharactersValidator dynamically depending on the self.pk to self.fields[field] (one field of the form) Thank you in advance and sorry if this questions is dumb.
