Get all items with all properties using django multi-table inheritance and django rest framework (Cart Product)
I'm using PostgresSQL as DB, Django as backend and HTML, CSS, Javascript as Frontend. I have refer this question link but doesn't help me. Let me explain the whole scenario about my website. 1.

Get a value from the url to set it as a value of the form?
I'm making a poll app where you have 2 options yes or no (Boolean), I want to save not only a number of votes but also who voted so I decided to make a "pivot" model connecting the User model and the Poll model like this: models.py # Vote choices BOOL_CHOICES = ((True, 'Yes'), (False, 'No')) class PollVotes(models.Model): user = models.ForeignKey(userModels.User, on_delete=models.CASCADE, blank=True) vote = models.BooleanField(choices=BOOL_CHOICES) poll = models.ForeignKey(Poll, on_delete=models.CASCADE) Its easy to set the user value using form.instance.user = self.request.user this way: (views.py) class PollVote(CreateView): model = PollVotes form_class = VoteForm template_name = 'poll_vote.html' success_url = reverse_lazy('polls') def form_valid(self, form): form.instance.user = self.request.user form.instance.poll = ????? return super(PollVote, self).form_valid(form) I'm thinking of getting the poll pk from the URL, but don't know how to do it. Right now the URL gets a int value this way: path('poll/vote/<int:poll>/', PollVote.as_view(), name='poll-vote'), How to relate that int:poll to a PK of some Poll? And then setting the form.instance.poll as a Poll with the PK of the URL? Maybe it's the wrong approach, it's just what I think will be the easiest way. forms.py class VoteForm(forms.ModelForm): class Meta: model = PollVotes fields = ['vote'] widgets = { 'vote': forms.RadioSelect } -

Form created dynamically always gets 403 forbidden on a django rest framework api POST
I have multiple text posts on my website. On clicking the edit button I dynamically create a form replacing the div to a form element. I have my POST api set up on the django side to get this form submit and edit the existing post. But my POST request always gets 403. First i assumed not having a csrf token is causing the problem. So i edited my js code to this- //form create const post_content_element = post.querySelector('div .text-content'); const post_content = post_content_element.innerHTML; let edit_form = document.createElement('form'); // Here I added the csrf token as a hidden input let inputElem = document.createElement('input'); inputElem.type = 'hidden'; inputElem.name = 'csrfmiddlewaretoken'; inputElem.value = '{{ csrf_token }}'; edit_form.appendChild(inputElem); edit_form.setAttribute('id', 'edit-form'); edit_form.setAttribute('method', 'POST'); let text_content = document.createElement('input'); text_content.setAttribute('type', 'textarea'); text_content.setAttribute('id', 'edit-content'); text_content.value = post_content; let submit = document.createElement('input'); submit.setAttribute('type', 'submit'); submit.setAttribute('id', 'edit-submit'); edit_form.appendChild(text_content); edit_form.appendChild(submit); still it gets 403 forbidden. My api looks like this- @api_view(['POST']) def edit_post(request): if request.method == "POST": # do something return Response(status=status.HTTP_201_CREATED) Please note I am using my User(AbstractUser) model for authentication. I am out of ideas. What could be the other reasons for this problem? -

How do I remove the JWT Authentication requirements from certain models? Django Rest API / Axios
I have a few models, some of them just holds images and information I want to display on the screen (BEFORE the user logs in) I followed a guide to setup my JWT authentication for users, and I created the other models myself. I'm getting Unauthenticated messages when I try to do a .get() on my other models, which I do not want them to need to be authenticated. I want anyone to be able to login, and see that information. What is a simple way, I can remove the authentication requirements from these models? I never set up any JWT for these models, so I am surprised the user model which has JWT is effecting these.. but anyways. I'm pretty new to coding. I cannot find anything on google to answer this question. How can I send some information through my axios get request to say, "HEY THIS DOESN"T NEED TO BE AUTHENTICATED." Like, a master key to get me through that requirement. enter image description here enter image description here enter image description here enter image description here -

The problem I have currently is that all of my variable names essentially start with similar patterns and end with similar patterns. This ID is generated from somewhere else so I'm hoping I can do something to use it effectively. The pattern ID format essentially looks like... "#id_newbudgetlineitem_set-0-line_item_october" "#id_newbudgetlineitem_set-0-line_item_november" "#id_newbudgetlineitem_set-0-line_item_december" I want to essentially matching on the set-* but only if it's identical to the other ids in my array. Is this even possible without having to hard code anywhere from set-0 to set-1000? Unfortunately the class for each one is the same as is the name situation. Is there someway to say if the set numbers all match in a given array then add them up? I can't use starts with or ends with in this case...and don't want to hardcode 1000 possibilities. Thanks in advance for any ideas or thoughts. -
