Django - File remove button for InlineFormSet not working
I have 2 models, OwnerListing and OwnerListingPhoto, the latter is a ForeignKey to the former. I'm using InlineFormset to allow the user to edit an existing OwnerListing with all of its respective OwnerListingPhoto's. On the site, the formset is shown like this. Everything else is working fine, except the delete function. When you check the 'Delete' checkbox and submit the form, the form is successfully submited, but the photo is not deleted. What's going on in my code that is causing this? def fsbo_edit_listing(request): listing = OwnerListing.objects.get(id=int(request.GET.get('id'))) PhotoFormSet = inlineformset_factory( OwnerListing, OwnerListingPhoto, fields=('photo',), widgets={ 'photo': ClearableFileInput(attrs={'class': 'btn btn-outline-secondary form-control'}) } ) if request.method == 'POST': form = OwnerListingForm(request.POST, instance=listing) photo_formset = PhotoFormSet(request.POST, request.FILES, instance=listing) if form.is_valid() and photo_formset.is_valid(): form.save() for i in photo_formset: if i.instance.pk and i.instance.photo == '': i.instance.delete() elif i.cleaned_data: temp = i.save(commit=False) temp.listing = form.instance temp.save() return redirect('dashboard') else: if listing.user == request.user: form = OwnerListingForm(instance=listing) photo_formset = PhotoFormSet(instance=listing) else: raise Http404('Not a valid request') return render(request, 'fsbo_create_listing.html', {'form': form, 'photo_formset': photo_formset}) HTML: {{ photo_formset.management_form }} {% for form in photo_formset %} <div class="col-sm-6 col-xl-4 mb-3 p-1" style=""> <div class="col-12 border border-dark rounded p-2"> {{ form }} </div> </div> {% endfor %} -

Parent page option keeps appearing
I'm working on a Python/Django/Wagtail project. At some point when creating an Article it could go under the Articles index model or the Partners index model. I deleted all of the Partners traces in the code, and the Article model only has this: parent_page_types = ['btcmag.ArticleIndexPage'] However when creating an Article, I still get the same screen showed above. Am I missing some step? -

Incomplete json structure - no count/next/previous/results field
like many times before, im trying to send data from my Django backend to my Ionic mobile app. This time, however, for some reason, the .jsons im parsing are coming out incomplete. A complete .json: {"count":1,"next":null,"previous":null,"results":[{"codigo":"qwe","area":"ewq","especies":[],"id":1}]} My incomplete .json: [{"nome_ficheiro":"1520529086252.jpg","id":26,"especie":"Ameijoa Branca","zona":"L6","data":"09/06/2018"}] IONIC is struggling with identifying what I'm parsing as a .json, which makes sense since there is no "results" field. Here are the relevant snippets of my django code: Views.py (both Views are doing the same thing! This is just me trying out different approaches!) class resultUploadViewSet(viewsets.ViewSet): def list(self, request, nome_ficheiro): queryset = labelResult.objects.all() nome = nome_ficheiro answer = queryset.filter(nome_ficheiro=nome) serializer = resultSerializer(answer, many=True) return Response(serializer.data) class resultUploadView(APIView): serializer_class = resultSerializer def get(self, request, nome_ficheiro): queryset = labelResult.objects.all() nome = nome_ficheiro answer = queryset.filter(nome_ficheiro=nome) serializer = self.serializer_class(answer, many=True) return Response(serializer.data) Models.py class labelResult(models.Model): nome_ficheiro = models.CharField(max_length=120) especie = models.CharField(max_length=120) zona = models.CharField(max_length=120) data = models.CharField(max_length=120) Urls.py urlpatterns = [ url(r'results/(?P<nome_ficheiro>.+)/$', resultUploadViewSet.as_view({'get': 'list'})), url(r'results1/(?P<nome_ficheiro>.+)/$', resultUploadView.as_view())] Serializers.py class resultSerializer(serializers.ModelSerializer): class Meta: model = labelResult fields = ('nome_ficheiro','id','especie','zona', 'data') Any idea why my .jsons are coming out incomplete? -
Django - How can I open multiple stored files and render them as HTML?
I have a user account that can create a model called experiment. Within this model, it can store files: HTML, JS, and CSS. It stores them in the server. My issue right now is trying to figure out how to approach this problem of rendering the HTML file on a page. Do I try to create a view that has an HTTP response of the file? Is there a better way? -

How to save images from RTF editor in Django project?
I have been able to use Alloy Editor (a fork of CKEditor) and save the formatted texts in Django model. I have used AJAX to capture the input and save the data with the following code. $(document).ready(function() { $('#create_form').on('submit', function(e) { e.preventDefault(); $.ajax({ url : '/create/', type : 'POST', data : { title : $('#id_title').val(), body : $('#id_body').html() }, success : function() { $(location).attr('href', '/'); } }) }); }); However, when I select an image in the editor and hit the save button I am shown a 400 bad request error in the console. I am guessing that for the image to be used within the article I am trying to save I have to upload the image in the media folder and put a link to that uploaded image in the place where I have placed the image in the RTF editor. How can I do this? -

Setting DEFAULT_FILE_STORAGE in settings.py triggers "TypeError: Unicode-objects must be encoded before hashing"
I'm setting up my app to work with AWS.

If I comment out DEFAULT_FILE_STORAGE = app.aws.utils.MediaRootS3BotoStorage the error message goes away. I've searched relentlessly but I haven't found anything to point me in the right direction.

Querying all objects including soft deleted ones of a SoftDeletableModel
I'm try to get rid of home-brew solution to favor more standard ones. My previous pattern: class MarkDeleteManager(models.Manager): use_for_related_fields = True def get_queryset(self): if "instance" in self._hints: return super(MarkDeleteManager, self).get_queryset() return super(MarkDeleteManager, self).get_queryset().filter(deleted=False) def all_with_deleted(self): return super(MarkDeleteManager, self).get_queryset() def deleted_set(self): return super(MarkDeleteManager, self).get_queryset().filter(deleted=True) def using(self, *args, **kwargs): ''' if a specific record was requested, return it even if it's deleted ''' return self.all_with_deleted().using(*args, **kwargs) I'd like to replace this with django-model-util's SoftDeletableModel but I don't see any all_with_deleted like functionality in the SoftDeletableManagerMixin - it only overrides get_queryset and that's it. My architecture is decentralized, and when I notify other nodes about soft deletions I need to access those. -

Test case data stays in Django development database Selenium

After little investigation I realized a user with credentials from test cases is already created in my database. Thus, when I ran test case for second time it failed to create a new user, as user with these details is already present. (I can see user from Django admin). I believe this is not the expected behaviour of LiveServerTestCase(or any type of test case). In setup, a temporary database is created, test case is ran on it, and destroyed in tearDown phase.

Here's what I have tried: From views.py: def payment_process(request): paypal_dict = { 'business': settings.PAYPAL_RECEIVER_EMAIL, 'amount': '5.00', 'item_name': 'Certificate from INC.', 'currency_code': 'USD', 'ret urn_url': 'http://127.0.0.1:8000/users/done', 'cancel_return': 'http://127.0.0.1:8000/users/cancel', 'isPayment': 'True', } valid_ipn_received.connect(show_me_the_money) form = PayPalPaymentsForm(initial=paypal_dict) return render(request, 'users/generateCert.html', {'form': form}) @csrf_exempt def payment_done(request): print(valid_ipn_received.connect(show_me_the_money)) return generate_certificate(request) @csrf_exempt def payment_canceled(request): return render(request, 'users/payment_canceled.html') def generate_certificate(request): template = get_template('users/certificate_template.html') minutes = int(request.user.tagging.count()) * 5 testhours = minutes / 60 hours = str(round(testhours, 3)) context = { "fullname": request.user.first_name + ' ' + request.user.last_name, "date": datetime.date.today(), "hours": hours, "today": "Today", } html = template.render(context) pdf = render_to_pdf('users/certificate_template.html', context) if pdf: response = HttpResponse(pdf, content_type='application/pdf') filename = "Invoice_%s.pdf" % "12341231" content = "inline; filename='%s'" % filename download = request.GET.get("download") if download: content = "attachment; filename='%s'" % filename response['Content-Disposition'] = content return response return HttpResponse("Not found") Here are my Templates: generateCert.html {% block content %} {% csrf_token %} … -
Trying to replace default HTML widgets
I'm making a framework to improve the development of an existing system. My main task was to make said system responsive, and we settled in using material design. we're using django version 1.9. We've tried a lot of existing frameworks (django material, grappelli, etc), but we decided to develop our own, because if we were to use an existing framework we'd have to hack the sh*t out of it, basically. The thing is, right now I need to be able to render HTML widgets so that materialize (the library we're using) displays them nicely. I know that, as far as what I've read (pretty much anywhere), this is not possible by default. So I've come up with two ways to do so (I implemented a quick and dirty version of the second and it works, kind of), but I find both of them to be extremely... not elegant. The first one consists on creating our own database fields, inheriting from the ones defined in django, overwriting the formfield method to use custom form fields (which we would create by inheriting from django's ones and making them use our custom widgets). I (clearly) haven't implemented this one because it seems to … -
How to pass custom elements list to the class attribute properly?
I have the line in my template: <div class="class1 class2 class3 {{ foo_classes }}"> If the foo_classes is empty I get class="class1 class2 class3 ". What I want to get is class="class1 class2 class3" with no additional space at the end of the classes list. <div class="class1 class2 class3{{ foo_classes }}"> If I delete the space (look at the line above) then I get class="class1 class2 class3class4 class5", which is no better. How do I pass additional classes to avoid getting unnecessary space at the end of the classes section if the foo_classes is empty?
