Django - what is the best way to avoid doing repetitive queries in a dynamic navbar?
I'm currently developing a project which has two apps. When the user logs into the system, the navbar will show the links according to what permissions the user has in the database. If the user only has permissions for app 1, the links it will show will only correspond to this app, the same if it only has permission for app2. If the user has permission for both the navbar will show all the links of both apps. Being dynamic the navbar has to make queries to the database. so I want to avoid making a query every time a page is loaded. I have thought that an option is, in the view, to make the query a first time and then store it with request.session: Try: #If the query has already been made, it accesses the saved value query = request.session['navbar'] Except: # If the query has not been made, makes it and saves it in request.session['navbar'] request.session['navbar'] = #QUERYCODE This is a good way to handle the problem? is there another better way? -
How to filter a query on Django ORM
I know this should be pretty basic but somehow I don't quite get it. I want to get all users which age is lesser than 18 so the query should be something like this User.objects.filter(age < 18) what Im doing wrong? -
Django - If i put 2 formsets together in my view, the function to add multiple times the same views doesnt work
I have this code bellow. Im using formset to add multiple times the same form. But if i put this 2 formsets together, like in my view, just the first data for each form is saved. And if i put just 1 formset in my def, it works, all datas for i put to the form is saved. Someone have any idea why this is happening? (sorry for my eng) Forms.py class InsereIdioma(forms.ModelForm): class Meta: model = Idioma fields = '__all__' exclude = ['usuario'] InsereIdiomaFormset = formset_factory(InsereIdioma, extra=1) class InsereTecnologia(forms.ModelForm): class Meta: model = Tecnologia fields = '__all__' exclude = ['usuario'] InsereTecnologiaFormset = formset_factory(InsereTecnologia, extra=1) Views.py def cadastro_curriculo(request): if request.method == 'GET': formset_idioma = InsereIdiomaFormset(request.GET or None) formset_tecnologia = InsereTecnologiaFormset(request.GET or None) elif request.method == 'POST': formset_idioma = InsereIdiomaFormset(request.POST) formset_tecnologia = InsereTecnologiaFormset(request.POST) if formset_idioma.is_valid(): for form in formset_idioma: idioma = form.cleaned_data.get('idioma') fluencia = form.cleaned_data.get('fluencia') if idioma and fluencia: Idioma( idioma=idioma, fluencia=fluencia, usuario=request.user ).save() if formset_tecnologia.is_valid(): for form in formset_tecnologia: sistema = form.cleaned_data.get('sistema') nivel = form.cleaned_data.get('nivel') if sistema and nivel: Tecnologia( sistema=sistema, nivel=nivel, usuario=request.user ).save() return render(request, "personal/curriculo.html", { 'formset_idioma': formset_idioma, 'formset_tecnologia': formset_tecnologia, }) -
Post HTML input tag file data to another input tag file and retrieve in Django views
I'm trying to send one <input type="file"... value to another <input type="file".. using Javascript. I've created an HTML form and after filling it, I want to review the form. Then submit that form in my FormFill model through views.py. So far what I have done is creating 2 different Divs for the same work. In div1, I'm sending my form data using action="javascript:reviewForm()" and in reviewForm(), I'm setting all the form data of div1 to div2 form using document.getElementById('cfname2').value = document.getElementById('cfname1').value; It's setting all the values and then posting it to views.py successfully except my <input type="file" name="pic2".. data. Since python retrieves form POST data using request.FILES['pic2'], in div2 I don't have file data to Post. So far what I've tried is: document.getElementById('pic2').value = document.getElementById('pic1').value; where, In div1 I have <input type="file" id="pic1"... and in div2, <input type="file" id="pic2"... My models.py class FormFill(models.Model): pic = models.ImageField(upload_to='candidates/pics/') ... How can I post the div2 image data to views and then to Django models? Note: I don't want to Post the div1 data directly to Django models since I want my users to first review the form that they have filled. And that's why using the concept of 2 Divs. Thanks in … -
Chaining querysets in managers
I am looking for a way to reuse this abstract model/manager with queryset on the models that require soft delete but some of my models already have custom managers/querysets. Ideally I would like all of those other managers to use SoftDelete manager/queryset so that they would always return only undeleted items. Is there a way to achieve this in Django 1.10? class SoftDeleteQuerySet(QuerySet): def delete(self): for obj in self: obj.is_active = False obj.save() def undelete(self): for obj in self: obj.is_active = True obj.save() class SoftDeleteManager(Manager): def get_queryset(): return SoftDeleteQuerySet(self.model, using=self._db).filter(is_active=True) class SoftDelete(Model): is_active = m.BooleanField(default=True) objects = SoftDeleteManager() class Meta: abstract = True def delete(self): self.is_active = False self.save() def undelete(self): self.is_active = True self.save() -

pytest, How do you break up rather long test?
I'm writing my first pytest test, and it is rather long (currently 120 lines) It tests the store's checkout process, What it does is roughly following: grab product info add_to_cart add purchaser information (phone, name, address etc) (extra) add coupons or points to use create an order from cart handle payment (bypassing actual payment gateway, but still need to do something like stock decreasing, change order status etc) cancel the order (because created order data needs to be reused, I'm putting them together) How to break up pytest tests when many objects need to be shared.. -

How to figure out NoReverseMatch at / in Django
Hi and thank you for your time Im using Django and i've got a following issues: NoReverseMatch at /dashboard/. NoReverseMatch at /event/. When i try to go to the dashboard page or to the event_list page i get the error.

How do I make and access regex capture groups in Django without RawSQL?
How do I annotate a Django queryset with a Regex capture group without using RawSQL so that I later can use that value for filtering and sorting? For example, in PostgreSQL I could make the following query: CREATE TABLE foo (id varchar(100)); INSERT INTO foo (id) VALUES ('disk1'), ('disk10'), ('disk2'); SELECT "foo"."id", CAST((regexp_matches("foo"."id", '^(.*\D)([0-9]*)$'))[2] AS integer) as grp2 FROM "foo" ORDER BY "grp2" dbfiddle -
Jquery POST in Django (continued)
I have read the 2 posts related to this subject. Can't make them apply to my case: I get a word that I pick from a radio button. I send that word via jquery ajax POST to a view function. That word should serve the purpose of filtering the query set like the WHERE in a sql query. Then the other issue is how I can get the proper content so that I can write it in the html template. I got that when I was not using jquery but now that I do, don't know how to use what I get from the view function. JQUERY $(document).ready(function(){ $('input[type="radio"]').click(function(){ var valor = $(this).val(); $.post('home', {valor:valor}, function(data)) $('#feedback').text(data); // this won't help. I actually need something like what I get with return //render(request, 'home.html', {'listoflanguages': listoflanguages}) }); }); VIEW FUNCTION def home(request): valor = request.POST.get('valor') listoflanguages = Language.objects.values('language','lesson', 'description', 'url').order_by('language', 'lesson').annotate(count=Count('lesson')) listoflanguages = listoflanguages.filter(valor) # I want to filter it here WHERE... return render(request, 'home.html', {'listoflanguages': listoflanguages}) AND THE TEMPLATE {% for item in listoflanguages %} <tr> <td class="align-middle">{{ item.language }}</td> // how can I implement what I get from the view? etc etc -
Django 2.2.x returns on specific computer: The requested resource was not found on this server

How Not Duplicate Submit Form - without JavaScript - DJango
The objective of this is create an input where the user introduce username, there are 2 buttons that submit the form with OK or NO. The problem is that when I submit the form everything is going well but when 'reload' button is pressed the form is sent it again and the username is written in the database. How can I avoid this? Just submit the form, save the username in database, and then show the success message Preventing POST on reloading a form? This is the code: view.py def notificationchecker(request): user = '' # comprobamos cookie de usr try: user = request.COOKIES['user'] except Exception as e: print("Not cookie found: " + str(e)) finally: if user is not '': form = CheckerForm(initial={'user': user}) else: form = CheckerForm() # comprobamos cookie de success notification try: success = request.COOKIES['success'] date = request.COOKIES['date'] response = render( request, 'notificationchecker/notificationchecker.html', {'form': form, 'success': success, 'date': date, 'user': user} ) response.delete_cookie('success') response.delete_cookie('date') return response except Exception as e: print("Not cookie found: " + str(e)) return render( request, 'notificationchecker/notificationchecker.html', {'form': form, } ) def notificationchecker_result(request): form = CheckerForm(request.POST) if request.method == "POST": if form.is_valid(): ntchecker = form.save(commit=False) ntchecker.device = request.user_agent.ua_string ntchecker.option_selected = request.POST['option_selected'].lower() date = timezone.now() ntchecker.checked_date … -

When to use form methods
I am reading the Django documentation and ran across a couple examples in the forms sections that I do not understand why they did something 2 separate ways.. In the first example I found they send email from the FBV. This makes a lot of sense to a beginner. from django.core.mail import send_mail if form.is_valid(): subject = form.cleaned_data['subject'] message = form.cleaned_data['message'] sender = form.cleaned_data['sender'] cc_myself = form.cleaned_data['cc_myself'] recipients = ['info@example.com'] if cc_myself: recipients.append(sender) send_mail(subject, message, sender, recipients) return HttpResponseRedirect('/thanks/') In the second example I found they use CBVs and apply methods to the form and call this method in the view: from django import forms class ContactForm(forms.Form): name = forms.CharField() message = forms.CharField(widget=forms.Textarea) def send_email(self): # send email using the self.cleaned_data dictionary pass from myapp.forms import ContactForm from django.views.generic.edit import FormView class ContactView(FormView): template_name = 'contact.html' form_class = ContactForm success_url = '/thanks/' def form_valid(self, form): # This method is called when valid form data has been POSTed. # It should return an HttpResponse. form.send_email() return super().form_valid(form) When should you apply form methods and call those methods in the view? Is there a benefit to writing the code this way? Also, in the second example they used pass in the send_email() … -

Connect two Django apps with same initial workflow
I have a django project whereby the initial workings of two apps is essentially the same. Therefore, I have split the initial workings (a couple of forms) into its own init application. The idea is then to continue the workflow in the application in one of the two apps (app1 or app2). The idea is to connect the success_url of the last FormView in the init app to the index url of the app to use. I have thought about using sessions to store the url from app1 and redirect to the init app but this has its own implications due to the use of sessions, ie expiry etc. How else could the 'bridge' be performed? -

Django M2M field in a Model Form?

How can I properly catch errors of a Node js script in Python using Naked?
I am using Naked library of Python mentioned here for executing a Nodejs script which is also available here too. The point is, whenever I run my python script(exactly taken from the above link) through the terminal I can able to see the output of the nodejs script. I included this python script into my Django server and running it whenever an API call is made. I couldn't able to catch the errors properly when the validation of the page fails. It always returns 'success'. I feel this is because Nodejs is asynchronous. If it is so, how can I make the function 'amphtmlValidator.getInstance().then(function(validator)' mentioned in the npm website to synchronous? I am really very much new to Nodejs. Actually I just need to validate AMP pages from python script in Django and the only way I found is calling the node script through python. Everything is ok, but I couldn't catch the errors properly. Please help.
