Why am I sometimes logged out of Django Admin?
Since the deployment of my Django website on Digitalocean with Nginx and Gunicorn I have the problem that I either can not log in to the admin panel and he jumps on the registration form again and again or when I am logged in, then only very briefly and then he jumps back again. In between, he also shows the error "Too many redirects" Nginx Config -
Cant upload pictures in django forms
I'm just getting started with Django and encountered the first problem that I can't solve. From the admin level, photos can be uploaded, but from the form on the website it is impossible. The only picture that can be uploaded is the default picture I set in the models file. If I delete the default picture from models and upload the photo from the form, an error pops up. Here are some of my files: models.py class Post(models.Model): author = models.ForeignKey('auth.User', on_delete=models.CASCADE) title = models.CharField(max_length=200) text = models.TextField() created_date = models.DateTimeField(default=timezone.now) publish_date = models.DateTimeField(blank=True, null=True) image = models.ImageField(upload_to='images/', blank=True, null=True, default='images/user.jpg') def publish(self): self.publish_date = timezone.now() self.save() def __str__(self): return self.title forms.py: class PostForm(forms.ModelForm): class Meta: model = Post fields = ['title', 'text', 'image'] views.py: class Image(TemplateView): form = PostForm template_name = 'blog/image.html' def post(self, request, *args, **kwargs): form = PostForm(request.POST, request.FILES) if form.is_valid(): obj = form.save() return HttpResponseRedirect(reverse_lazy('image_display', kwargs={'pk': obj.id})) context = self.get_context_data(form=form) return self.render_to_response(context) def get(self, request, *args, **kwargs): return self.post(request, *args, **kwargs) class ImageDisplay(DetailView): model = Post template_name = 'blog/image_display.html' context_object_name = 'image' def post_list(request): posts = Post.objects.filter(publish_date__lte=timezone.now()).order_by('publish_date') return render(request, 'blog/post_list.html', {'posts': posts}) def post_detail(request, pk): post = get_object_or_404(Post, pk=pk) return render(request, 'blog/post_detail.html', {'post': post}) def error_404_view(request, … -

500 IIS Internal server error near Fetch Api in django
I have deployed a django web application through Microsoft IIS. The deployment seems to be successful except for the error I am getting while submitting a form.

Multiple Sites with Django and Apache - Can't get both to work at the same time
We have two sites made in Django, one is a fork of the other (same project name) so we had issues with the wrong settings.py loading for the second site in mod_wsgi. So we put mod_wsgi into Daemon mode to hopefully separate the two more so this didn't happen. One works fine when the other is either disabled or configured incorrectly. Once the second site is made to what should work, it doesn't and it brings the first one down with it, giving us an Apache 500 Error. Here is the conf.d file we have for one of them: WSGIDaemonProcess {siteName}.co.uk python-home=/var/www/vhosts/{siteName}.co.uk/venv python-path=/var/www/vhosts/{siteName}.co.uk/website/{djangoProject} WSGIProcessGroup {siteName}.co.uk WSGIScriptAlias / /var/www/vhosts/{siteName}.co.uk/website/{djangoProject}/{djangoProject}/wsgi.py WSGIPythonHome /var/www/vhosts/{siteName}.co.uk/venv WSGIPythonPath /var/www/vhosts/{siteName}.co.uk/website/{djangoProject} <VirtualHost *:80> ServerName {siteName}.co.uk ServerAlias www.{siteName}.co.uk <Directory /var/www/vhosts/{siteName}.co.uk/> Options Indexes FollowSymLinks MultiViews AllowOverride All </Directory> <Directory /var/www/vhosts/{siteName}.co.uk/website/{djangoProject}/{djangoProject}> <Files wsgi.py> Require all granted </Files> </Directory> CustomLog /var/log/httpd/{siteName}.co.uk-access.log combined ErrorLog /var/log/httpd/{siteName}.co.uk-error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

Can't display the children items (packets) that contain the same dev_address as the selected parent item (device) in React.js
(Please check below for screenshots) I have a relational DB where every packet belongs to only one device (through a foreign key dev_address) and a device can have many packets (many-to-one rel). I've been trying to display the packets that belong to the selected device which is in a mapped list. I'm using context to load packets and devices from the API. The stack is React-Django-MySQL. Can someone please direct/help me on the method I should use to resolve this?

Render a string containing a django template, form and svg
I'm new to django and I have a problem, I want to render a string like httpresponse does but the problem is that the string is the content of an html file containing a django template and an svg code. Httpresponse does not interpret the django template and the django csrf_token. IT just copies them as text. For example: def mysresponse(request): ch= " {% extends 'base.html' %} {% block content%}form django and svg content {%endblock%}" return httpResponse(ch) This code copies the templates {% extends 'base.html' %} {% block content%}, {%endblock%} but interprets the svg and form content except the csrf_token. Is there a way to do this please? Thank you very much -

How can we override Dango ModelAdmin queryset over ModelForm queryset?
Requirement is to display M2M instances in a dropdown for different logins. Each login will be able to see only instances belonging to their own domain. Since this dropdown is a dynamic list of table row values, I want to use widget = forms.CheckboxSelectMultiple which is part of the ModelForm where we need to pass the queryset. This queryset overrides the M2M form field definition: def formfield_for_manytomany(self, db_field, request, **kwargs): It doesn't filter as per the login and displays all the objects. I don't want to use the default <Ctrl +> for selection from the dropdown. Not very good with any JS related code. Please quide.

Java Script accordion functionality problem
Im making a app in django which needs a accordion. This is the following HTML code {% load static %} {% for comp in comps %} <script src="{% static 'main/app.js' %}"></script> <div class="accordion-body"> <div class="accordion"> <div class="container"> <div class="label"> {{comp.name}} {{comp.country}}, {{comp.city}} </div> <div class="content">{{comp.descr}}</div> <hr> </div> </div> </div> {% endfor %} This is the css which actually hides the content. Note Ive taken out a lot of uneccessary css like font-size and colors. .accordion .label::before { content: '+'; top: 50%; transform: translateY(-50%); } .accordion .content { text-align: justify; width: 780px; overflow: hidden; transition: 0.5s; } .accordion .container.active .content { height: 150px; } Finally this is javascript which is meant to add a Event Listener const accordion = document.getElementsByClassName('container'); accordion.addEventListener('click', function () { this.classList.toggle('active') }) The active class isnt being added. There might be a problem with linking the js with the HTML doc since when I run the app this is what I get in the command line. GET /static/main/app.js HTTP/1.1 The location is definitely correct -
