How can I choose which choice to show up in django form field?
I am trying to dynamically change the viewable choices in a django form choice field depending on the user. Here is my form: SubmitForm(forms.ModelForm): class Meta: model = Lesson fields = ( "status", ) Here is my models.py for Lesson: CLASS_STATUS = ( ('Attended', 'Attended'), ('Absent', 'Absent'), ('Teacher Postponed', 'Teacher Postponed'), ('Student Postponed', 'Student Postponed'), ) status = models.CharField( max_length=30, choices=CLASS_STATUS, null=True, blank=True, ) So, basically I want to be able to select which choices to show for each type of user. In order to do this, I hope you guys could also show how I could access the request.user information in my form. Thank you, and please ask me any questions you have. -
post request 413 Error django with gunicorn
class test(BaseListView): def post(self,request): data=json.loads(request.body.decode('utf-8')) url = 'other server API' res=requests.post(url, json=json.dumps(data)) print(res.status_code) return 'ok' This is the code. 'data' i put as a request body to send this data to other server. and when i printed res.status_code i got 413 error. It's because the data size is big.(1GB) the size of the request body depends on the platform or webserver. I think this is the problem in gunicorn. i found this solution on docs but i don't know how to use it. https://docs.gunicorn.org/en/latest/settings.html#limit-request-line If anyone has other solution or how to use --limit-request-line INT command line i would be thankful. Currently, i put my gunicorn.service on /etc/systemd/system and to start the server i command "sudo systemctl restart gunicorn" this is how gunicorn.service looks like [Unit] Description=gunicorn daemon After=network.target [Service] User=ubuntu Group=www-data WorkingDirectory=/home/ubuntu/django-boilerplate/mysite ExecStart=/home/ubuntu/django_env/bin/gunicorn \ --workers 3 \ --bind 0.0.0.0:8000 \ mysite.wsgi:application [Install] WantedBy=multi-user.target -
Django: how to access field attributes in a template
I have a form for updating an object with an image field styled with bootstrap. And right now it just looks ugly: is there a way to access individual html elements like form.image.label_tag, so i can style them? I would definitely like to remove this line break in the middle. django template: <div class="input-group"> <span class="input-group-text"> <label for="{{ form.image.auto_id }}"><i class="{{ form.image.label }}"></i></label> </span> {{ form.image|add_class:"form-control" }} </div> html i am getting: <div class="input-group"> <span class="input-group-text"><label for="id_image"><i class="bi bi-image"></i></label></span> Currently: <a href="/media/dishes/27.jpg">dishes/27.jpg</a> <input type="checkbox" name="image-clear" id="image-clear_id"> <label for="image-clear_id">Clear</label> <br> Change: <input type="file" name="image" accept="image/*" class="form-control" id="id_image"> </div> -
NginX location management with Django&Vue.js setup
I have a Django backend and Vue.js frontend served by the same machine. I want a specific path to be directed to the django API and admin panel, while the rest should load Vue index.html and be passed to Vue router. My problem is, that while the base path is passed on to Vue.js, and my selected path does go through to Django, any other path results in 404, which means that if I want to revisit a path generated though Vue router, it's impossible to do so. I figured the problem must be somewhere in the NginX config file: # the upstream component nginx needs to connect to upstream myproject { server unix:///tmp/myproject .sock; } server { listen 80; listen [::]:80; server_name serverurl.com; return 301 https://serverurl.com$request_uri; } server { listen 443 ssl; listen [::]:443 ssl; ssl_certificate /home/projects/myproject/ssl/ANY.serverurl.com.crt; ssl_certificate_key /home/projects/myproject/ssl/ANY.serverurl.com.key; server_name serverurl.com www.serverurl.com; access_log /home/projects/myproject/logs/nginx_access.log; error_log /home/projects/myproject/logs/nginx_error.log; location / { root /home/projects/insights/vue/dist; try_files $uri $uri/ /home/projects/myproject/vue/dist/index.html =404; } location /backend/ { include /etc/nginx/uwsgi_params; uwsgi_pass myproject; } location /static/ { alias /home/projects/myproject/static/; } location /media/ { alias /home/projects/myproject/media/; } } So the "/" path results in correctly rendering Vue index.html And "/backend/" correctly loads django urls But, for example, if the … -

How to add pagination to a django ReadOnlyModelViewSet or ListAPIView?
I have a Django Restframework project. Here is my view: class JobView(viewsets.ReadOnlyModelViewSet): queryset = Job.objects.all() serializer_class = JobSerializer filter_backends = [filters.OrderingFilter, DjangoFilterBackend, filters.SearchFilter] search_fields = [...] ordering_fields = ['jobId'] ordering = ['-jobId'] filterset_fields = ['jobId', 'status'] pagination_class = StandardResultsSetPagination and my pagination class: class StandardResultsSetPagination(LimitOffsetPagination): page_size = 1 The view is registerd in a router: router.register(r'jobs', JobView) The problem is, it does not paginate at all. It just ignores the pagination_class attribute. I also tried: class JobView(generics.ListAPIView) And registered the view without the router. But the problem is the same. It does not paginate and just returns a json list with all jobs. How can achieve pagination in this view without defining it for the project in settings.py globally? -

Django login not working. Page just refreshes a new login page
I have a project called django_swing. Within this project i have 2 different app. One is interface and the other is users. Within the django_swing folder for urls.py, I have the following: path('login/', auth_views.LoginView.as_view(template_name='users/login.html'), name='login'), Within the interface folder for urls.py, I have the following: path('', views.home, name='interface-home'), Within the interface folder for views.py, I have the following: def home(request): return render(request, 'interface/home.html', {'title':'Home'} ) I have the file for home.html. As it is very long, I cant paste here. When i run the project, 127.0.0.1 loads the page for home.html. Lastly, within the django_swing folder for settings.py, I have the following at the bottom of the file: STATIC_URL = '/static/' LOGIN_REDIRECT_URL='interface-home' LOGIN_URL = 'login' But when i access 127.0.0.1/login and key in with a account i just made followed by pressing the login button, the page refreshes with the same login page and the url becomes http://127.0.0.1:8000/login/?#. It is not jumping to interface-home as declared in settings.py. Can anyone advise me on how to solve this? I am a beginner at this. Thank you very much! -
