Django Picture showing as broken when referenced in template
I am trying to create a settings page for user profiles and I have hit a roadblock. I included a profile image inside of my User model and when trying to reference said ImageField in my profile template the image shows up as broken. Firstly, everything else related to the storing of a profile image works. When an account is created, the default image saves and same with using the upload picture form. The issue comes when trying to display the current profile picture through the model's url and the image shows up as broken. models.py class Profile(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) id_user = models.IntegerField() bio = models.TextField(max_length=300, blank=True) profileimg = models.ImageField(upload_to='profile_images', default='blank-profile.jpg') verified = models.BooleanField(default=False) def __str__(self): return self.user.username views.py def settings(request): user_profile = Profile.objects.get(user=request.user) if request.method == "POST": if request.FILES.get('image') == None: image = user_profile.profileimg bio = request.POST['bio'] user_profile.profileimg = image user_profile.bio = bio user_profile.save() if request.FILES.get('image') != None: image = request.FILES.get('image') bio = request.POST['bio'] user_profile.profileimg = image user_profile.bio = bio user_profile.save() return redirect('settings') return render(request, 'settings.html', {'user_profile': user_profile}) Section of html file that tries to show image <img width="100" heigh="100" src="{{ user_profile.Profileimg.url }}" /> I have also added all of the necessary MEDIA_URL/root settings and have tried … -
Django form not showing errors but redisplays new form
I have a Insert view which displays model data from one primary and one related model. Once finished displaying the data a form is appended to the table to add a new related item. This works fine - however if I enter invalid data (like a invalid time to be exact), and hit one of the submit buttons, it simply refreshes the page with a blank entry form for the related data again. It doesn't display the data I entered, and it doesn't display an error message even though the form includes the error fields. I have tried adding form_invalid to my CBV and calling the form but I can see that it just calls the InserView again with no context (which basically does the get_context_data call again and give me a new blank form). How do I get it to put up the form with my data from before and the errors as well. See code below: views.py class SegmentAddView(LoginRequiredMixin,CreateView): login_url = reverse_lazy('login') model = Segment template_name = 'segment_add_view.html' form_class = SegmentForm def get_context_data(self, **kwargs): context = super(SegmentAddView,self).get_context_data(**kwargs) program_info = get_object_or_404(Program, pk=self.kwargs['pk']) context['program_info'] = program_info last_segment = program_info.segments.last() if last_segment: add_sequence_num = last_segment.sequence_number + Decimal(1.00) else: add_sequence_num = Decimal(1.00) … -
Django: Display data from other table

Parse &-character in GET query using Django and Vue
We are using axios to pass GET request to our django instance, that splits it into search terms and runs the search. This has been working fine until we ran into an edge case. We use urlencode to ensure that strings do not have empty spaces or others So generalize issue, we have TextField called "name" and we want to search for term "A & B Company". However, issue is that when the request reaches django. What we expected was that name=A%20&%20B%20Company&field=value would be parsed as name='A & B Company' and field='value'. Instead, it is parsed as name='A ' 'B Company' and field='value'. The & symbol is incorrectly treated as separator, despite being encoded. Is there a way to indicate django GET parameter that certain & symbols are part of the value, instead of separators for fields? -

Relational queryset not showing properly in template
