Add Radio button in default Django form:
I think I have written the correct code. But this gender radio button is not appearing in my form. This is my model view. class Charter(models.Model): CHOICES = [('M', 'Male'), ('F', 'Female'), ('O', 'Others')] Gender = forms.ChoiceField(label='Gender', widget= forms.RadioSelect(choices=CHOICES)) created_at = models.DateField() First_name = models.CharField(max_length=200, unique=True) Last_name = models.CharField(max_length=200, unique=True) address = models.CharField(max_length=200, unique=True) Cell_no = models.CharField(max_length=200, unique=True) created_at = models.DateField() This is my forms.py from django.forms import ModelForm from .models import * class CharterForm(ModelForm): class Meta: model= Charter fields = '__all__' widgets = { 'Gender': forms.RadioSelect() } -

Elastic search in Django with no query, only filter
I have a Django project for which I'm converting the regular DB search to elastic search. What currently happens is that there is a select to retrieve data from the DB based only on a date, basically to retrieve the most recent items. I'm trying to reproduce this behaviour with the django_elasticsearch_dsl but it keeps failing. I need a queryset because of how the whole app is structured. The method to_queryset() works just fine if I have a query term, but I get an error object of type 'Search' has no len() if I there is no query term. Something I tried: search = document.search() if query: search = search.query("multi_match", query=query, fields=["title", "body", "excerpt"]) search = search.filter("range", modified_at={"gte": date_from}) search = search.filter("range", modified_at={"lte": date_till}) object_list = search.to_queryset() This is inside a django arctic app, if that's relevant. I also tried using search = search.query() (with no params) and then adding the filters, but I get the same error. It sounds silly but is this possible to do? -

Why Django form_valid is calling twice?
I am using form_valid() to save my data from form and redirecting to specific page using a condition in get_success_url but form_valid() is calling twice. i saw some people resolved with: return HttpResponseRedirect(self.get_success_url()) and return HttpResponseRedirect(self.request.META['HTTP_REFERER']) But found no help with my condition.

How to add an attribute to the form tag itself and not just a field in Django?
I am having trouble stopping bots filling in spam while letting through legit users. I have a honeypot field with autocomplete="off" attribute but it doesn't seem to be working. From what i've read, the best cross browser solution is to add autocomplete="false" to the main form tag itself, e.g. <form autocomplete="false">...</form>. What is the best way to do this in Django? -
Django - create submodels of a model
I want to create submodels(I do not know if this is the correct term to use) of a model. For example, let's say I have a model called Post. But I want this model's fields changable by users. Like users select their Post type. Right now I want to create a two different types: first is a class TextBasedPost(models.Model): title = models.CharField(max_length=100) content = RichTextField() # which has been imported from ckeditor.fields author = models.ForeignKey(User, on_delete=models.CASCADE) datePosted = models.DateTimeField(default=timezone.now) def __str__(self): return self.title def get_absolute_url(self): return reverse('post_detail',kwargs={'pk':self.pk}) Other one is a post with only image attachment: class ImageBasedPost(models.Model): title = models.CharField(max_length=100) image_attachment = models.ImageField(default='default.png', upload_to='profile_pics') # there will not be a usage of default.png author = models.ForeignKey(User, on_delete=models.CASCADE) datePosted = models.DateTimeField(default=timezone.now) def crop_image(self): img = Image.open(self.image.path) # Image imported from PIL if img.height > 600 or img.width > 600: output_size = (600,600) img.thumbnail(output_size) img.save(self.image_attachment.path) def __str__(self): return self.title def get_absolute_url(self): return reverse('post_detail',kwargs={'pk':self.pk}) But like you see this is not good way to use since there are same fields and same functions in both models(only one fields and one function is different). But this is not a good practice. So is there a way to do this with better way? -
model obj is returning same object

How to disable automatic URL parameter decoding in Django?
I have a viewset with a retrieve view, which takes one parameter, which is a string url encoded, as it often has '/' in it. Now when I send a request to my local development server with the url encoded (every / replaced by %2F) I get a 404 from my server and in the "Request URL" I see my string but decoded - so it makes sense that there is no such route. The route shows up correctly in this debug view with api/ ^topic/(?P<pk>[^/.]+)/$. This is my viewset: class TopicAPI(viewsets.ViewSet): def retrieve(self, request, pk=None): if '%2F' in pk: pk = pk.replace('%2F', '/') # Data retrival which works (independently tested) return Response(topics) I tried different words and different replacement methods, i.e. '--' instead of '2%F' which works but isn't nearly as stable as url encoding.
