Manually rendered form fields do not save data
I really wanted to figure this out myself and I spent over 4 hours on the subject but I give up now. I have a form that is supposed to save data, and if I lay out the form with the {{ form }} tag everything works great. If I put in to form with individual tags like {{ form.client_email }}, the form data is not saved to the database. I need to render these fields manually for front end purposes but I just couldn't figure out how to do it. I appreciate your help a lot. Here is my code. views.py def client_list_view(request): if request.method == 'POST': form = ClientModelForm(request.POST) if form.is_valid(): client_title = form.cleaned_data["client_title"] client_email = form.cleaned_data["client_email"] client_turkishid_no = form.cleaned_data["client_turkishid_no"] client_tax_no = form.cleaned_data["client_tax_no"] client_tax_office = form.cleaned_data["client_tax_office"] client_contactperson = form.cleaned_data["client_contactperson"] client_phone_number = form.cleaned_data["client_phone_number"] Client.objects.create( client_title=client_title, client_email=client_email, client_turkishid_no=client_turkishid_no, client_tax_no=client_tax_no, client_tax_office=client_tax_office, client_contactperson=client_contactperson, client_phone_number=client_phone_number ).save() return redirect("books:client-list") else: form = ClientModelForm() client_list = Client.objects.all().order_by("client_title") context = {'client_list' : client_list, "form": ClientModelForm} return render(request, 'clients/client_list.html', context=context) Working template <div id="clientModal" class="modal bottom-sheet"> <div class="modal-content"> <form method="POST"> {% csrf_token %} {{form}} <button class="btn">Ekle</button> </form> </div> </div> Not Working Template <div id="clientModal" class="modal bottom-sheet"> <div class="modal-content"> <div class="row"> <div class="col s12"> <ul class="tabs"> <li class="tab … -

Django + nginx security in production
I recently found a big security breach in a project I did with django.

Delete db item in Django Python via Javascript button
I have written a small application in which want to build in a function which provides the possibility to delete database items (stored earlier) via a html button and Jinja (dynamic link building). Models.py Forms.py Views.py Etc. Have all been updated correctly. However the problem in building the link to delete a certain item gets triggered by the fact that i can't seem to succes in passing the db item (item.id) to the dynamic link because i have decided to put a javascript pop-up in between that asks for a confirmation before deleting the item. All attempts have failed until now. After endless searching for a solution i hope anyone can help me with this... First i generated a for loop that displays all the items in the db to which i have added a button "delete". This buttons triggers a javascript pop-up which works fine asking if the item must be deleted or the command should be cancelled. i don't seem to succeed in putting the dynamic link behind the last confirmation button. Python > Django > HTML > HTML Jinja > Javascript > HTML Jina For the moment the link has been build (lacking any better solution) as … -

How would you write an `is_pdf(path_to_file)` function in Python?
I have a Django project that creates PDFs using Java as a background task. Sometimes the process can take awhile, so the client uses polling like this: The first request starts the build process and returns None. Each subsequent request checks to see if the PDF has been built. If it has been, it returns the PDF. If it hasn't, it returns None again and the client schedules another request to check again in n seconds. The problem I have is that I don't know how to check if the PDF is finished building. The Java process creates the file in stages. If I just check if the PDF exists, then the PDF that gets returned is often invalid, because it is still being built. So, what I need is an is_pdf(path_to_file) function that returns True if the file is a valid PDF and False otherwise. I'd like to do this without a library if possible, but will use a library if necessary. I'm on Linux. -
Upload multiple images with Django Rest Framework
I am trying to upload multiple images from a Vue app to a Django Rest Framework api. Works fine for one image and thanks to this post I made it work for multiple images. But it feels like I missed something and I was wondering how I could improve this code. It feels like hacky code because: the serializer only returns one serialized object (and although it works the serialized object seems odd) I now need to create another serializer for simple get requests with one single image Should I split the images at view level a call a simple serializer with many=True? In create method or perform_create method? Tried a couple of things but without success Thanks for any help you may provide! models.py class Photo(models.Model): project = models.ForeignKey(Project, on_delete=models.CASCADE, related_name='photos') owner = models.ForeignKey(User, on_delete=models.CASCADE, related_name='photos') image = models.ImageField(upload_to=upload_path) view.py class PhotoViewSet(viewsets.ModelViewSet): serializer_class = PhotoSerializer permission_classes = (IsOwner,) parser_classes = (MultiPartParser, FormParser,) def perform_create(self, serializer): serializer.save(owner=self.request.user) def get_queryset(self): user = self.request.user project = self.request.query_params.get('project') if user.is_authenticated: return Photo.objects.filter(owner=user, project=project) raise PermissionDenied() serializers.py class PhotoSerializer(serializers.ModelSerializer): image = serializers.ListField( child=serializers.ImageField(allow_empty_file=False) ) class Meta: model = Photo fields = ['id', 'image', 'project'] def create(self, validated_data): images = validated_data.pop('image') for image in images: … -
Django 2.2 and Rest Framework 3.11 - partial updating model "owner" field (ForeignKey) with owner's username string instead of pk
Django 2.2 and Rest Framework 3.11 I have an Alarm model. Every alarm instance can optionally have an owner (the standard django User model). I want to be able to partially update (PATCH) an alarm by setting its owner just using his/her username (string) instead of the pk. Right now, I can update an alarm's owner only by using his/her pk. I tried various things, like: override the update() method in the AlarmSerializer class but whenever I use the owner's username string instead of the pk in the PATCH call, I get back: { "owner": [ "Incorrect type. Expected pk value, received str." ] } play with nested serializers and lookup_field but no luck so far. The api call (PATCH) should look like this: url: /api/alarms/{alarm_id}/ Payload: { "owner": "owner_username" } How can I do that? Thanks models.py from django.db import models from django.conf import settings class Alarm(models.Model): """ this class is meant to represent a network alarm (a.k.a. event or ticket) coming from some monitoring system (Zabbix, Nagios, etc.) """ customer = models.CharField(max_length=50) owner = models.ForeignKey( settings.AUTH_USER_MODEL, models.SET_NULL, blank=True, null=True, ) managed = models.BooleanField(default=False, blank=False, verbose_name="Managed ?") device_type = models.CharField(max_length=150) ... serializers.py from django.contrib.auth.models import User from rest_framework import … -
Django permission not working when variable in Axios request
I ran into a really strange error today while setting up restrictions on some of my Vue pages. I'm attempting to make this GET request: try { let actors = await $axios.$get(`/api/v1/users/${loggedInUser.id}/`); return { actors }; } catch (e) { return { actors: [] }; } }, I get back an empty actors [] object, but if I swap out ${loggedInUser.id} with just 1: try { let actors = await $axios.$get(`/api/v1/users/1/`); return { actors }; } catch (e) { return { actors: [] }; } }, I get back the actors: [] object I want. ({{loggedInUser.id}} returns 1 in the template). In Django I have the permission for this user's group set to myapp|user|Can View user Is there some reason that the variable in the Axios call is messing with the perms? I've tried already something like : const id = loggedInUser.id and await $axios.$get(`/api/v1/users/id/`) -

Using primary keys in Django and connecting multiple CBVs in database
I am incredibly new to Django and I'm struggling to get something to work in my project even after extensive research (I've been trying this over and over for about 2 days straight now and I'm sure I'm not finding the right answer because I'm probably not looking for the right question).

Recently I've been using AWS S3 for file storage (primarily hosting on Heroku) via ImageField uploads. I feel like there's a better way to store files than what I've been doing. For some things (like for the examples above) I think it would make sense to actually just get an image url from a more publically available url than take up space in my own database. For the experts in the Django community who have built and deployed really professional projects, do you typically store files directly into the Django media folder via ImageField? or do you normally use a URLField and then pull a url from an API or an image link from the web (e.g., go on any Google image, right click and copy then paste image URL)? Hope this makes sense. Thanks in advance! -
Instead of form.save() update entry if already exists
So I'm building an auction site where users can bid on active listings. The lister can then choose to close the listing and all the bids that have been placed will appear and they can choose a winner. After a lot of tweaking, I've managed to get my placebid view set up and I'm quite happy with how it is working. The problem is if a user has already placed a bid, rather than a new bid is placed I want that existing bid to be located and then updated. What is currently happening is when I click to close the bid I am seeing several bids placed all by the same user which isn't very helpful. My functioning views.py looks like this: def placebid(request, id): listing_bid = get_object_or_404(Listing, id=id) highest_bid = Bid.objects.filter(bid_item_id=id).aggregate(Max('bid_input'))['bid_input__max'] or Decimal('0') currentHighest = Bid.objects.filter(bid_item_id=id).aggregate(Max('bid_input'))['bid_input__max'] listing = Listing.objects.get(pk=id) if request.method == "POST": bidform = BidForm(request.POST) if bidform.is_valid() and highest_bid == 0: bid_placed = bidform.cleaned_data['bid_input'] if bid_placed <= listing.start_price: messages.error(request, 'Make sure your bid is greater than the start price') return HttpResponseRedirect(reverse("listing", args=(id,))) else: newbid = bidform.save(commit=False) newbid.bidder = request.user newbid.bid_input = bidform.cleaned_data['bid_input'] newbid.bid_item = listing_bid newbid.time = timezone.now() newbid.save() messages.success(request, 'Bid placed succesfully') return HttpResponseRedirect(reverse("listing", args=(id,))) if … -
How can I change the name(s) of folders in my Django project without destroying its ability to find its own parts?
I'm reading through Two Scoops of Django and the authors note that best practices involve having a config folder and an apps folder. I've been building a Django project for the last few months here & there and want to get in the habit of complying with these practices, but when I change the name of my <project_name> folder (with the wsgi, settings, etc.), Django can't seem to find the contents of the folder anymore. How do I change this folder name and put the project apps into an app folder without breaking the connections they have?
