Django Inlineformset not saving in class based updateview
I have a Book and Chapter model with one-to-many relationship. In my views.py I have two classes ChapterEdit and ChaptersManage, to update one Chapter and all Chapters respectively. I am using inlineformset for the ChaptersUpdate view to edit all the chapters that belong to a book. But when I update, the POST request doesn't do anything. The view is not saving the changes to the DB. I don't see any errors either. views.py class ChaptersManage(LoginRequiredMixin, UpdateView): login_url = reverse_lazy('login') model = Book fields = ["title", "order"] template_name_suffix = '-manage' #book-manage.html slug_field = 'slug' slug_url_kwarg = 'book_slug' def get_context_data(self, **kwargs): context = super(ChaptersManage, self).get_context_data(**kwargs) if self.request.POST: context['formset'] = ChapterFormSet(self.request.POST, instance=self.object) context['book'] = self.get_object() else: context['formset'] = ChapterFormSet(instance=self.object) return context def form_valid(self, form): context = self.get_context_data() formset = context['formset'] with transaction.atomic(): self.object = form.save() if formset.is_valid(): formset.instance = self.object formset.save() return super(ChaptersManage, self).form_valid(form) forms.py class ChapterEditForm(ChapterForm): def __init__(self, *args, **kwargs): super(ChapterEditForm, self).__init__(*args, **kwargs) class Meta(ChapterForm.Meta): fields = ChapterForm.Meta.fields ChapterFormSet = inlineformset_factory( Book, Chapter, form=ChapterEditForm, fields=('title', 'order'), extra=0) What am I missing? -

Using multiple dropzones in one form and sending data to django which takes only one request
First I am a beginner in dropzone and javascript. I have one html form, 3 instances of dropzone and the view.py. I want to send with each instance of dropzone different types -> Pictures, documents and videos. There are also data like char and int which I packed in the picture instance by using formData.append. So far I am able to get data from the first instance (picture) by using mydropzone.processQueue() when I fire the submit button on my form. How do I get the other files from the other dropzones into that request? Here the html part: <form id="postform" action="" method="POST" enctype="multipart/form-data" > {% csrf_token %} {{ form.media }} {% include 'Admin/includes/customformfield.html' %} <div id="dropzoneBild" class="dropzone"></div> <div id="dropzoneVideo" class="dropzone"></div> <div id="dropzonePdf" class="dropzone"></div> <div class="row-6"> <button class="btn btn-primary btn-round" type="submit" name="Submit">Submit</button> </div> </form> Here the dropzone instance for picture. The other two dropzones are the same except that the paramName is different and there is no formData.append for the char and int, also the acceptedFiles is different: (function () { var postform = document.getElementById('postform'); Dropzone.autoDiscover = false; var myDropzonebilder = new Dropzone("div#dropzoneBild", { url: postform.action, paramName: "filebilder", autoProcessQueue: false, uploadMultiple: true, parallelUploads: 50, maxFiles: 50, addRemoveLinks: true, acceptedFiles: ".jpeg,.jpg,.png", init: … -

making a battle royle result sheet. (django)
I have made a model class Results. It stores 'position' of a team and 'kills' secured by team during a tournament. The model class is as follows:- class Results(models.Model): teams=models.ForeignKey(Teams,null=True,on_delete=models.CASCADE) position= models.IntegerField(blank=True,null=True) kills=models.IntegerField(blank=True,null=True) matches=models.ForeignKey(Matches,null=True,on_delete=models.CASCADE) placement_point=models.IntegerField(null=True,default=0) kill_points=models.IntegerField(null=True,default=0) total_points=models.IntegerField(null=True,default=0) now, the team which get 1st postion gets 10 placement points, 2nd get 8, 3rd get 6, 4th get 5, 5th get 4 and all other teams get 0 placement points. Also each kill give 1 kill points(ex 15 kill-> 15 points). This position vs position points is also stored in table class PointsTable(models.Model): position=models.IntegerField(null=True) placement_point=models.IntegerField(null=True) kill_points=models.IntegerField(null=True,default=1) here teams represent individual team like fnatic, cloud9 etc. You can ignore matches field in Results class. All i want to automatically calculate and fill total_points, placement_point, kill_points. Example :- if fnatic get 2nd position with 15 kill then placement_point=8, kill_points=15*1,total_points=8+15=23. actually i m trying to solve this problem using django signal. But i m stuck.Kindly help me out, Thanks. -

Why is my Django form returning the QueryDict without the submitted data?
The issue I'm having is that my form data returns not None nor the form values I entered, but simply just the usual csrf_token string and the button's value. I verified this by printing Form(response.POST).data, which returns a QueryDict with just the csrf_token value and the value of the submit button: <QueryDict: {'csrfmiddlewaretoken': ['the token string'], 'save_customer': ['save_customer']}> Contrast this with the other working form's output that works. (I happen to be executing both procedures nearly identically): <QueryDict: {'tail': ['aasdf'], 'aircraft': ['asdf'], ...it's all here... 'csrfmiddlewaretoken': ['the token string'], 'add': ['add']}> So basically, my HTML file includes 2 forms. One form works, and the other doesn't. Having more than one form shouldn't be an issue, especially considering one form is in it's own separate container, and the other form resides in a modal. They do not share any "divs" with each other, nor any "parenting". However, it should be noted that the 2nd form's corresponding view is automatically executed on page load and without any prior doing. The simple existence of the second form causes this to happen. I've deleted the javascript files, removed all traces of javascript functionality within the second form, and yet the view still gets called … -

Custom Token Authenticating for external microservices in Django DRF
I am using a CustomTokenAuthentication class which extends Django rest framework's Token authentication. class CustomTokenAuthentication(TokenAuthentication): keyword = 'Bearer' def authenticate_credentials(self, key): # username = get_username() username = self._fetch_authorized_user(key) User = get_user_model() user = User(username=username) return user, key _fetch_authorized_user(key) uses an external login client to login users. Question: How do I extend this for external system authentication i.e. Allowing other microservices to authenticate and access these APIs as well. The external login client can't be touched so _fetch_authorized_user(key) will not find a valid username. I'm thinking of adding a fallback when that happens but what would that be? Is it Django's own authentication? (Creating a db and creating profiles for valid external microservices). Can both even work in parallel? Open to other suggestions -
django get filtered by parameter
The site I am building has 6 profiles (desks) and these are accessed via buttons at the top of the page using: path('home/<slug:slug>/', HomeView.as_view(), name='homepage') and is accessed by a button with: {% url 'homepage', slug=desk.slug %} So is filtered in the queryset. How can I access what that value so I can use it in the template for styling purposes? basically I want to highlight the desk button on the page so the user has visual feedback on where he is. Is there a way to do this nicely, as currently the only way I can think of doing this is to use: {% request.url %} and then split off the end of the url, but that seems like a nasty hack to me. Unfortunately google can't get past the word filter so all I get is django-filter documentation and issues.
