How to enable all lookups for all fields in django-filters library

Django Teamplate Tabs Not Showing
I have a Django website which you can think of as a blog. In there, I have a route where you can create a new post. There is also a list page and a detail page, where you can see all the posts published, and see the contents of the post respectively. When creating a new post, I have not added CKEditor or any other WYSIWYG editor. But if I have any tabs in the post, it doesn't render. For example, if I write some code in VSCode and paste it in the TextField, even though the tabs render in the TextField, the tabs don't appear in the detail page. For example, if I write this in the TextField: foo = "bar" if foo == "bar": print("baz") This, in the detail page looks like this: foo = "bar" if foo == "bar": print("baz") This is the part of my detail page that renders the above on the screen: <div class="contents"> {{ object.contents | linebreaks }} </div> Could you help? -
How to add extra key-value to QuerySet lists?
I am working with Django,i need to retrieve data from multiple database, which has different database name but with same table column structure. So I use model.using(database).all()to get queryset and merge them into one. I want to add extra databasename to indicate the data's database name, this is my code. model: class Sections(models.Model): apply_id = models.PositiveIntegerField() pathology_id = models.CharField(max_length=128) user_id = models.PositiveIntegerField() updated_at = models.DateTimeField(blank=True, null=True) get_queryset: def get_queryset(self): slideset = [] database_config = ['database1', 'database2', 'database3'] for i, x in database_config: slides = Sections.objects.using(x).all() #### I want to add extra databasename column in every query object. for x1 in slides: x1.databasename = x ###### slideset.append(slides) # merge QuerySet query = functools.reduce(lambda a, b: a|b, slideset) return query.order_by("updated_at").reverse() the one return will be : { "apply_id": 1123, "pathology_id": 1235, "user_id": 1, "updated_at": "202106011430", # add extra databasename. "databasename": "database1". } Because the column can't be modify, so I had to leave Sections model unchange, just add extra key-value to query, can someone help me on that? -

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 -

How can I fetch data by joining two tables in django?
Looking for help got stuck at a point, I am new to python and django. There ARE two payments corresponding to one order, one COLLECTION and multiple TRANSFER and i need the payment corresponding to an order whose direction is COLLECTION only NOT transfered yet so that i can initiate TRANSFER against that order models.py class Orders(models.Model): id= models.AutoField(primary_key=True) payment_gateway_code = models.CharField(max_length=20,choices=[('PAYTM','PAYTM')]) is_active = models.BooleanField(default=True) class Payments(models.Model): id = models.AutoField(primary_key=True) orders = models.ForeignKey(Orders, on_delete=models.CASCADE) direction = models.CharField(max_length=20,choices=[('COLLECTION','COLLECTION'), ('TRANSFER','TRANSFER')]) settlement_status = models.CharField(max_length=50,blank=True, null=True,choices=[('YES','YES'), ('NO','NO')]) is_active = models.BooleanField(default=True) qualified_orders = Orders.objects.filter(payment_gateway_code='CASHFREE', Exists(Payments.objects.filter(order=OuterRef('pk'), direction='COLLECTION', settlement_status='YES')), ~Exists(Payments.objects.filter(order=OuterRef('pk'), direction='TRANSFER'))) But above query is not working
