How to have Django templates display slugs
Hi guys i am new to django...i been watching youtube videos and reading books on Django but am still struggling with templates.

django.db.utils.OperationalError: no such table - after deleting all Django migrations
I had some issues with my database(design) and deleted all migrations, but not the db.sqlite3 file. I then rewrote my models.py, re-registered them inadmin.py and ran python3 manage.py makemigrations and python3 manage.py migrate. Both seemed to work fine and create the tables.

Django access fields of model with many to many relationship
So I have the following models: class Image(models.Model): image=models.ImageField(upload_to='postimages') id=models.UUIDField(default=uuid.uuid4, editable=False, unique=True, primary_key=True) class Post(models.Model): title=models.CharField(max_length=500) created_date=models.DateField(auto_now=True) id=models.UUIDField(default=uuid.uuid4, editable=False, unique=True, primary_key=True) images=models.ManyToManyField(Image) user=models.ForeignKey(get_user_model(), on_delete=models.CASCADE, null=True, related_name='posts') In my views I have created a post object like this: post=Post(title=title) post.save() post.images.add(image) Now I need to diplay the image field of the Image model in my homepage.

'NoneType' object has no attribute 'nazev_zanru' although it should have
Good day community, I need your help as I cannot proceed with my project. Django model.py returns an AttributeError: 'NoneType' object has no attribute 'nazev_zanru' My models.py is as follows; from django.db import models class Zanr(models.Model): nazev_zanru = models.CharField(max_length=80, verbose_name="Žánr") def __str__(self): return "Nazev_zanru: {0}".format(self.nazev_zanru) class Meta: verbose_name = "Žánr" verbose_name_plural = "Žánry" class Film(models.Model): nazev = models.CharField(max_length=200, verbose_name="Název Filmu") rezie = models.CharField(max_length=180, verbose_name="Režie") zanr = models.ForeignKey(Zanr, on_delete=models.SET_NULL, null=True, verbose_name="Žánr") def __str__(self): return "Nazev: {0} | Rezie: {1} | Zanr: {2}".format(self.nazev, self.rezie, self.zanr.nazev_zanru) class Meta: verbose_name = "Film" verbose_name_plural = "Filmy" As far as I understand, the def __str__(self): return "Nazev: {0} | Rezie: {1} | Zanr: {2}".format(self.nazev, self.rezie, self.zanr.nazev_zanru) code refers through zanr = models.ForeignKey(Zanr, on_delete=models.SET_NULL, null=True, verbose_name="Žánr") to class Zanr(models.Model): nazev_zanru = models.CharField(max_length=80, verbose_name="Žánr") def __str__(self): return "Nazev_zanru: {0}".format(self.nazev_zanru) ` which is therefore defined.

saving in stages in a django view
I am trying to get a field value from the database and modify it by getting the value from the page when it is rendered, The main issue is that I need to keep updating and savings the seconds every time the user refreshes the page. I want to do that on the same view where the user post his final response, I keep getting this error : IntegrityError: NOT NULL constraint failed: study_answer.completion_time although the field in the answer model has a default value: completion_time = models.FloatField(default=30) Completion time should be saved when the user finally submits the answer that comes from a different AJAX post call. views.py def attention_view(request): participant = get_object_or_404(Participant, user=request.user) attention_question = Question.objects.get(id=13) answer, created = Answer.objects.get_or_create(participant=participant, question=attention_question) seconds_left = int(answer.seconds_left) if request.method == 'POST': selected_choice = request.POST.get('selected_choice') completion_time = request.POST.get('completion_time') seconds_left = request.POST.get('left') seconds_left.answer=seconds_left if answer.answer is not None: return HttpResponseRedirect('/study/attention_view') print('already submitted') else: answer.answer = selected_choice answer.completion_time = completion_time answer.save() context = {'attention_question': attention_question, 'seconds_left':seconds_left, 'answer':answer} return render(request, 'study/AttentionCheck.html', context) I tried to save seconds_left in another view and it works but I want to save it in the same view where I have the GET request
