django-filter using filter class in another filter class
I use django-filter I have two models named Person and Member. Person has been defined as foreign key in Member. As an example here, I added less fields, normally the PersonModel model has a lot more fields. What I want to do here is to use all the filter fields I created for person in the filter class I created for Member. models.py class PersonModel(models.Model): name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) class MemberModel(models.Model) register_no = models.CharField(max_length=20, unique=True) person = filters.ForeignKey(PersonModel, on_delete=models.PROTECT, related_name='members') filters.py class PersonFilter(filters.FilterSet): name= filters.CharFilter(field_name='name') last_name= filters.CharFilter(field_name='last_name') class MemberFilter(filters.FilterSet): register_no = filters.CharFilter(field_name='register_no') # # I want to use PersonFilter here # for example: person = PersonFilter(lookup_expr="person") or how? # # I don't want to do it this way: # person_name = filters.CharFilter(field_name='person__name') # person_last_name = filters.CharFilter(field_name='person__last_name') -

Deploying Django on Heroku smart-open Causing Failure
Trying to deploy Django project to Heroku I get the following error: python setup.py egg_info did not run successfully. exit code: 1 error in smart_open setup command: 'python_requires' must be a string containing valid version specifiers; Invalid specifier: '>=3.6.*' note: This error originates from a subprocess, and is likely not a problem with pip. error: metadata-generation-failed Tried multiple versions of smart-open and tried removing it from requirements.txt, the invalid specifier is NOT in my requirements.txt (this is: smart-open==4.1.0) or I have tried multiple other versions, all break the build. I’ve tried changing setup tools on Heroku to eg setuptools==40.3.0, no dice (same errors). -
Django app not loading with DisallowedHost error even after adding IP to ALLOWED_HOSTS
I'm facing an issue with my Django web application deployment on an Amazon EC2 instance. The app is running using Gunicorn and Nginx as a reverse proxy. However, when I try to access the app using the public IP address (ipaddress:8000), it's not loading, and I keep getting a "DisallowedHost" error. Here are the steps I've taken so far: In my Django settings.py, I've added the public IP address to the ALLOWED_HOSTS setting: python Copy code ALLOWED_HOSTS = ['ipaddress:8000'] I've confirmed that Gunicorn is running and bound to ipaddress:8000 . Nginx is configured as a reverse proxy with the following settings: nginx Copy code server { listen 80; server_name ipaddress:8000 location / { proxy_pass http://ipaddress:8000 proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; } } Despite these configurations, the app still does not load, and I receive the following error in my Django logs: css Copy code [2023-08-02 17:28:00 +0000] [#] [INFO] Starting gunicorn 21.2.0 [2023-08-02 17:28:00 +0000] [#] [INFO] Listening at: http://ipaddress:8000 (#) ... DisallowedHost at / Invalid HTTP_HOST header: 'ip address'. You may need to add 'ipaddress' to ALLOWED_HOSTS. It seems like Django is still considering the request host as 'ipaddress', even though I've explicitly added it to ALLOWED_HOSTS. Any … -
Prevent custom django admin url from redirecting to change view
I have defined a custom django admin url that I am using as a custom action link in the changelist view and will also be used by the form posted in that custom view. # used in the overridden changelist.html <a href="{% url 'admin:get_monthly_report' %}">Get Monthly Report</a> # in the model admin def get_urls(self): urls = super().get_urls() urls += [ path( 'get_monthly_report/', self.admin_site.admin_view(self.get_monthly_report), name='get_monthly_report' ), ] return urls Problem is clicking on the link keeps trying to redirect the change view (doesn't make sense why Django is trying to guess instead of using the actual view defined for the URL). Given that what am doing is close enough to what is suggested in the documentation, either the documentation left this problem out or am doing something wrong -
Error when changing project server from Django to Azure
When I converted the website I have from Django storage to Azure, I got some errors I cant seem to fix.

Problem with picture tags in Django templates
I'm getting some issues with a picture tag in a Django template. The goal is easy, I'm just trying to add to my website an image which may be in Avif, Webp or JPG/PNG format. I've written my HTML as I've done several times before, but somehow it's not working as expected. So the problem is as follows: in a first try, the AVIF version (which corresponds to the first source tag) is well loaded 👌🏻, but if I delete it from the server (or change its name), I was expecting WebP version to be loaded, though the alt message is shown. This is my code: <picture> <source srcset="{% static 'my_app/img/' %}{{ topic.image|avif_image }}" type="image/avif"> <source srcset="{% static 'my_app/img/' %}{{ topic.image|webp_image }}" type="image/webp"> <img src="{% static 'my_app/img/' %}{{ topic.image|original_image }}" alt="{{ topic.name }} image" loading="lazy"> </picture> Note: avif_image, webp_image and original_image are just some custom filters I've created to return each image's name, while topic is the field sent from the view to the template. I realized that the browser is always trying to load the first source tag, I mean, if I reorder the code and set WebP as the first one, I get the same problem but the … -
How to sort by letter in Django
On my website, there are different listings arranged as (a-e), (e-j), (j-o), (o-t), and all.

how do I access a previously created from a page on a different page
I am trying to open a modal i created that shows a team member's info. I want this same modal to be linked to the team members' names on a differnt page so that the same info pops up when the name is clicked. the modal works fine in the team page, but I just can't seem to figure out how to have the same modal pop up on the other page.

Handle UploadedFile in csv.reader
I am trying to read an uploaded file without saving it: def import_file(request): if request.method != 'POST': form = UploadForm() else: form = UploadForm(request.POST, request.FILES) if form.is_valid(): rdr = csv.reader(request.FILES["file"], delimiter=',') for row in rdr: print(row) ... But I get iterator should return strings, not bytes (the file should be opened in text mode) If i was reading a file with open function, I could have opened it with 'rt'. But in this case I am dealing with InMemoryUploadedFile class if I'm not mistaken. So I can't re-open it. What is the correct aproach here? Based on simpilar topics I've tried using read() and decode("UTF-8") and decode("ISO-8859-1") on the InMemoryUploadedFile, but so far nothing worked. -
Django run raw sql on existing queryset
I'm using Django 3.2 and Django Rest Framework 3.12.2. We have some custom OrderingFilters that override OrderingFilter and manipulate the received queryset. We override the get_ordering() function of the OrderingFilter: def get_ordering(self, request, queryset, view): So far we used some of the django queryset abilities. Now, I want to run a raw sql as part of the ordering process. As far as I know, we can do something like - MyModel.objects.raw("select * from my_model.....") The problem is that as I see, we can only select from the whole table (my_model in that case) and not from the already prepared queryset. What I would like to be able to do is something like - query_set = MyModel.objects.filter(created_at='2023.03.07') raw_query_set = query_set.raw("select * from query_set ...") Is it possible in some way? -

Django why function can't be stopped with redirect to a specific URL
